"A Modelling Framework for the Conceptual Design of Low-Emission Eco-Industrial Parks in the Circular Economy: A Case for Algae-Centered Business Consortia."

Full textAbstract:
This article describes a unique industrial symbiosis employing an algae cultivation unit (ACU) at the core of a novel eco-industrial park (EIP) integrating fossil-fuel fired power generation, carbon capture, biofuel production, aquaculture, and wastewater treatment. A new modelling framework capable of designing and evaluating materials and energy exchanges within an industrial eco-system is introduced. In this scalable model, an algorithm was developed to balance the material and energy exchanges and determine the optimal inputs and outputs based on the industrial symbiosis objectives and participating industries. Optimizing the functionality of the ACU not only achieved a substantial emission reduction, but also boosted aquaculture, biofuel, and other chemical productions. In a power-boosting scenario (PBS), by matching a 660 MW fossil fuel-fired power plant with an equivalent solar field in the presence of ACU, fish-producing aquaculture and biofuel industries, the net CO2 emissions were cut by 60% with the added benefit of producing 39 m3 biodiesel, 6.7 m3 bioethanol, 0.14 m3 methanol, and 19.55 tons of fish products annually. Significantly, this article shows the potential of this new flexible modelling framework for integrated materials and energy flow analysis. This integration is an important pathway for evaluating energy technology transitions towards future low-emission production systems, as required for a circular economy.

An investigation was made to ascertain heavy metals concentration in effluent samples collected from textile industries located at Bhaluka industrial area, Mymensingh, Bangladesh during August to November, 2013. Atomic absorption spectrometer (AAS) was used to evaluate the concentration of Zinc (Zn), Copper (Cu), Nickel (Ni), Cadmium (Cd), Chromium (Cr) and Lead (Pb) in the samples. The study revealed that heavy metals were present in variable amounts, where the concentrations of Cu (0.0405 ppm) and Pb (0.0003 ppm) were found lower than recommended level for industrial waste water. Among the present trace metals, the highest concentration (0.2-1.0 ppm) was found in Zn. Although the concentration is suitable for irrigation, it is unsafe for aquaculture. Besides, all of the wastewater samples possessed no Cr, Cd and Ni, which comprised less of the minimum acceptance level, indicating no possibility of contamination. However, comparing findings of this study with the safe limits for industrial wastewater, it can be concluded that the waste water of the study area except some sampling sites can be used for irrigation and aquaculture.

Full textAbstract:
Abstract Aquaculture is currently one of the most rapidly growing food production industries in the world. The increasing global importance for this industry stems primarily from the fact that it is reducing the gap between the supply and demand for fish products. Commercial aquaculture contributes significantly to the economies of many countries since high-value fish species are a major source of foreign exchange. This review looks at the aquaculture industry, the issues raised by the production of fish through aquaculture for food security, the sustainability of the practice to agriculture, what the future holds for the industry in the next 10-20 years, and why there is a need to have available analytical procedures to regulate the safe use of chemicals and veterinary drugs in aquaculture.

Full textAbstract:
Integrated rice field aquaculture, a practice normally used by rural small-scale farmers, is not only supporting farms and livelihoods but is also reducing poverty and is playing a more and more important role in China. It is also becoming one of the main freshwater aquaculture systems, in addition to ponds, lakes, reservoirs, streams, and other aquaculture systems. During the past 40 years, both the production and areas of integrated rice field aquaculture in China have significantly increased from 0.13 million t and 0.74 million ha in 1990 to 3.25 million t and 2.56 million ha in 2020, respectively. Advances in ecology research on integrated rice–fish aquaculture were one of the main contributors to this achievement. In this paper, we systematically reviewed the advances in ecology research on three major integrated rice field aquaculture systems in China, namely rice–fish, rice–crab, and rice–crayfish coculture systems, the contribution of the research, and future prospects. We found that progress in ecology research on theories, biological studies, models, and eco-engineering techniques, coupled with policy support promoted the development of the rice field aquaculture industries. This review could assist individual small-scale farmers to make better use of rice field space to produce safer aquatic and rice products at a lower cost and help aquaculture scientists to further study the ecology of integrated rice field aquaculture systems.

Textile industries consume high quantity of water and release it as toxic effluents after some colouring processes. However, some wastewater may be recycled as fertilizers in aquaculture and agriculture, horticulture after dilutions. But industrial effluent of synthetic products like azo dyes may be harmful for germination and growth performance of crop seeds. The present paper deals with the physico-chemical parameters of textile industrial effluents and its impacts on germination and growth performance of Wheat, Triticum aestivum (Family: Gramineae/ Poaceae). Seeds were found more tolerant against 25% concentrated effluent.

Full textAbstract:
Aquaculture production is projected to expand from land-based operations to the open ocean as demand for seafood grows and competition increases for inputs to land-based aquaculture, such as freshwater and suitable land. In contrast to land-based production, open-ocean aquaculture is constrained by oceanographic factors, such as current speeds and seawater temperature, which are dynamic in time and space, and cannot easily be controlled. As such, the potential for offshore aquaculture to increase seafood production is tied to the physical state of the oceans. We employ a novel spatial model to estimate the potential of open-ocean finfish aquaculture globally, given physical, biological and technological constraints. Finfish growth potential for three common aquaculture species representing different thermal guilds—Atlantic salmon (Salmo salar), gilthead seabream (Sparus aurata) and cobia (Rachycentron canadum)—is compared across species and regions and with climate change, based on outputs of a high-resolution global climate model. Globally, there are ample areas that are physically suitable for fish growth and potential expansion of the nascent aquaculture industry. The effects of climate change are heterogeneous across species and regions, but areas with existing aquaculture industries are likely to see increases in growth rates. In areas where climate change results in reduced growth rates, adaptation measures, such as selective breeding, can probably offset potential production losses.

Full textAbstract:
The increase in partial pressure of CO2 in the oceans directly affects the productivity and survival of coastal industries and ecosystems. For marine aquaculture, the decreased alkalinity of seawater results in reduced availability of carbonates for marine organisms to build their shells, leading to decreased aquaculture quality and productivity. The industry has been implementing recirculating aquaculture systems (RASs) to reduce CO2 in feedwaters, but recent interest in ocean-based CO2 capture has led to additional strategies that may be relevant. The new methods in addition to CO2 removal offer capture options for enhanced aquaculture sustainability. Here, we review and compare early-stage and commercially available technologies for deacidification of seawater and their suitability for aquaculture. Most methods considered rely on a voltage-induced pH swing to shift the carbonate/bicarbonate equilibrium toward the release of CO2, with subsequent capture of the released CO2 as a gas or as solid mineral carbonates. The modular design and distributed deployment potential of these systems offers promise, but current demonstrations are limited to bench scale, highlighting the need for sustained research and development before they can be implemented for marine aquaculture.

Full textAbstract:
Marine Spatial Planning (MSP) provides a process that uses spatial data and models to evaluate environmental, social, economic, cultural, and management trade-offs when siting (i.e., strategically locating) ocean industries. Aquaculture is the fastest-growing food sector in the world. The United States (U.S.) has substantial opportunity for offshore aquaculture development given the size of its exclusive economic zone, habitat diversity, and variety of candidate species for cultivation. However, promising aquaculture areas overlap many protected species habitats. Aquaculture siting surveys, construction, operations, and decommissioning can alter protected species habitat and behavior. Additionally, aquaculture-associated vessel activity, underwater noise, and physical interactions between protected species and farms can increase the risk of injury and mortality. In 2020, the U.S. Gulf of Mexico was identified as one of the first regions to be evaluated for offshore aquaculture opportunities as directed by a Presidential Executive Order. We developed a transparent and repeatable method to identify aquaculture opportunity areas (AOAs) with the least conflict with protected species. First, we developed a generalized scoring approach for protected species that captures their vulnerability to adverse effects from anthropogenic activities using conservation status and demographic information. Next, we applied this approach to data layers for eight species listed under the Endangered Species Act, including five species of sea turtles, Rice’s whale, smalltooth sawfish, and giant manta ray. Next, we evaluated four methods for mathematically combining scores (i.e., Arithmetic mean, Geometric mean, Product, Lowest Scoring layer) to generate a combined protected species data layer. The Product approach provided the most logical ordering of, and the greatest contrast in, site suitability scores. Finally, we integrated the combined protected species data layer into a multi-criteria decision-making modeling framework for MSP. This process identified AOAs with reduced potential for protected species conflict. These modeling methods are transferable to other regions, to other sensitive or protected species, and for spatial planning for other ocean-uses.

Aquaponics is a hybrid food growing technology that combines the best of aquaculture (growing fish in an artificial aquatic environment and hydroponics (growing plants without soil in an aquatic nutrient environment). It is completely organic because the fish produces natural fertilizers used by the plants, which means no exogenous chemicals. Aquaculture has been around for a long time. Throughout the civilized world, aquaculture is one of the most dynamically developing industries, it is considered as a way to ensure food security and a means to combat poverty. Due to the need to provide the world population with high-quality and healthy fish and vegetable products, aquaponics, which is already one of the fastest growing agricultural and food sectors, has great potential for future development.

Finfish aquaculture is one of the quickly developing food industries in the world. But, the major drawbacks of this industry are the frequent outbreak of infectious diseases due to elevated stress in an intensive culture system. Antibiotics are extensively used to combat these diseases. Prophylactic administrations of antibiotics in aquaculture lead to the emergence and spread of antibiotic-resistant pathogens which indirectly cause a risk to health of human. Therefore, hard rules and regulations have been established in various countries to minimize or ban the application of antibiotics in finfish aquaculture. Recently probiotics have garnered significant attraction as an alternative measure for disease prevention in aquaculture. Probiotics increase health status, disease resistance, growth performance and feed utilization through improving hosts microbial balance. This review presents the summary and discussion of the results of the effects of probiotic administration in the culture of commercially important finfish. Besides, the current study attempts to explore the gap in present scientific information as well as suggests concerns that worth further research.

Full textAbstract:
Tourism has been growing and diversifying in recent years to become one of the fastest growing sectors of the economy in the world. Modern tourism is closely linked to economic development and is embracing an increasing number of new destinations. Such dynamics have transformed tourism into a key driver of socioeconomic progress. As for recreational tourism as one of the key species, it not only covers most of the related industries directly or indirectly, including transport, construction, trade, catering, agriculture, housing and communal services, culture, art, sports, etc., but also stimulates their development. The focus of recreational tourism on the sea and ocean coasts has expanded the range of tourism services. Aquaculture, which is becoming more relevant in the context of ecosystem conservation, is one of these areas of activity. Since aquaculture and tourism require certain requirements for water quality and the environment, there is an inevitable conflict of interest between entrepreneurs. And as research has shown, such conflicts have arisen in many countries. It has been found that solving this issue may not be the same for everyone. Only individual management, strategic planning and continuous monitoring will allow the effective development of coastal areas and profit for the country. Independent research conducted by the Scottish Research Forum found no evidence of a negative relationship between aquaculture and recreation. In many cases, aqua farms are of cognitive and gastronomic interest to tourists. The study also does not consider the development of aquaculture to be incompatible with tourism, but on the contrary it is an integrating process. Both industries are important to the economies of the countries, so in every territory where aquaculture and recreation can be mutually beneficial, a balance must be struck between them. The aim of the study is to analyze the specific aspects of aquaculture in Ukraine and in the world. The main objectives of our research are: to explore the role and importance of aspects of the introduction of recreational tourism in aquaculture; to analyze the current state of tourism in the world and its economic indicators; to identify the problems of intensification of recreational tourism in the coastal regions of the world; to offer the own vision of the prospects of integrating aquaculture into recreational tourism. Research methods. To achieve this goal there are used general scientific and special research methods in the work, such as: statistical method is for systematizing economic and statistical information on the development of tourism and aquaculture; methods of analysis and synthesis are for studying the functioning of aquaculture in general and its individual aspects; regional method is for studying the functioning of the industry in regional development; method of economic analysis is implemented in identifying trends, patterns and prospects of tourism and aquaculture.

SUMMARYParasites have a major impact on global finfish and shellfish aquaculture, having significant effects on farm production, sustainability and economic viability. Parasite infections and impacts can, according to pathogen and context, be considered to be either unpredictable/sporadic or predictable/regular. Although both types of infection may result in the loss of stock and incur costs associated with the control and management of infection, predictable infections can also lead to costs associated with prophylaxis and related activities. The estimation of the economic cost of a parasite event is frequently complicated by the complex interplay of numerous factors associated with a specific incident, which may range from direct production losses to downstream socio-economic impacts on livelihoods and satellite industries associated with the primary producer. In this study, we examine the world's major marine and brackish water aquaculture production industries and provide estimates of the potential economic costs attributable to a range of key parasite pathogens using 498 specific events for the purposes of illustration and estimation of costs. This study provides a baseline resource for risk assessment and the development of more robust biosecurity practices, which can in turn help mitigate against and/or minimise the potential impacts of parasite-mediated disease in aquaculture.

Korea is one of the most advanced countries in kelp aquaculture. The brown algae, Undaria pinnatifida and Saccharina japonica are major aquaculture species and have been principally utilized for human food and abalone feed in Korea. This review discusses the diversity, population structure and genomics of kelps. In addition, we have introduced new cultivar development efforts considering climate change, and potential carbon sequestration of kelp aquaculture in Korea. U. pinnatifida showed high diversity within the natural populations but reduced genetic diversity in cultivars. However, very few studies of S. japonica have been conducted in terms of population structure. Since studies on cultivar development began in early 2000s, five U. pinnatifida and one S. japonica varieties have been registered to the International Union for the Protection of New Varieties of Plants (UPOV). To meet the demands for seaweed biomass in various industries, more cultivars should be developed with specific traits to meet application demands. Additionally, cultivation technologies should be diversified, such as integrated multi-trophic aquaculture (IMTA) and offshore aquaculture, to achieve environmental and economic sustainability. These kelps are anticipated to be important sources of blue carbon in Korea.

AbstractRecent developments in food industries have attracted both academic and industrial practitioners. Shrimp as a well-known, rich, and sought-after seafood, is generally obtained from either marine environments or aquaculture. Central prominence of Shrimp Supply Chain (SSC) is brought about by numerous factors such as high demand, market price, and diverse fisheries or aquaculture locations. In this respect, this paper considers SSC as a set of distribution centers, wholesalers, shrimp processing factories, markets, shrimp waste powder factory, and shrimp waste powder market. Subsequently, a mathematical model is proposed for the SSC, whose aim is to minimize the total cost through the supply chain. The SSC model is NP-hard and is not able to solve large-size problems. Therefore, three well-known metaheuristics accompanied by two hybrid ones are exerted. Moreover, a real-world application with 15 test problems are established to validate the model. Finally, the results confirm that the SSC model and the solution methods are effective and useful to achieve cost savings.

The aquaculture economy of the Republic of Crimea is examined from the point of view of bioeconomics. Possibilities for growing, breeding and territorial distribution of aquaculture products have been identified. The main task is to study the possibilities for the production of marketable products of industrial mariosystems, both marine and freshwater, existing on the territory of the peninsula. Mapping in the ArcGis environment of the territorial distribution of enterprises engaged in fishing and fish farming was carried out. The biodiversity of autochthonous invertebrate breeding is estimated within the framework of a number of restrictions related to the conservation of biomass stocks, a set of key commercial species of aquaculture products. This approach allows you to scientifically substantiate the mechanisms for optimizing and developing this industry with different management strategies. A set of measures, both biological and economic in nature, is proposed for the implementation of the concept of inexhaustible fisheries, which will provide the population with a variety of indigenous products available to wide layers of the population with different income levels and satisfy the needs of adjacent industries for technical products, and will also be aimed at preserving biodiversity of aquatic ecosystems of the Black and Azov Seas by normalizing loads in the organization of recreational fishing.

Abstract Introduction More eco-friendly aquaculture technology is required to reduce environmental pollution which has become a major issue in aquaculture industries in the last few decades. Aquaponics system is a culture technology to solve this waste issue. Thus, this study aimed at comparing growth performances, feed utilization efficiency, and nutrient recovery in aquaponics and conventional aquaculture system. Materials and methods Twenty-four juveniles of Nile tilapia (Oreochromis niloticus) weighing 1.12 ± 0.1 g were cultured in either aquaponics systems or conventional aquaculture systems for 30 days. Each system had three culture systems as replicates. The fish were fed the same amount with a commercial pellet three times a day. Results The result showed that the Nile tilapia reared in the aquaponics system had a significantly higher specific growth rate than that of fish reared in the conventional system, 7.5 and 6.3% BW/day, respectively. Similarly, the feed utilization efficiency of fish reared in the aquaponics was also significantly better than that of fish in the conventional system. Furthermore, the total biomass harvested from the aquaponics system was nearly eight times higher than the total biomass harvested from the conventional system. Conclusion Growth, feed utilization efficiency, and total nutrient recovery in terms of biomass were higher in the aquaponics system. These results suggest that aquaponics is not only an eco-friendly aquaculture system, but also could produce more biomass than a conventional aquaculture system, and therefore, could be scaled up in a commercial scale.

Worldwide increased demand for offshore renewable energy (ORE) industries and aquaculture requires developing efficient tools to optimize the use of the offshore space, reducing anthropic pressure. The synergetic development of marine renewable energy infrastructure with mariculture has been hypothesized as a way to reduce costs through shared infrastructure. In the Irish Sea, blue mussels (Mytilus edulis L.) represent 40 - 50 % of the total gross turnover of Welsh shellfish industries and the industry has been operating sustainably for over 50 years in North Wales. However, the region is also attractive for tidal energy projects, with strong tidal currents (> 2m/s) occurring, and offshore wind farms, with shallow waters (approx. 50 m) and consistent winds. In this context, it is of scientific and economic interest to study the potential impact of ORE on shellfish larvae recruitment. A numerical approach has been developed using an Eulerian hydrodynamic model coupled with a Lagrangian particle tracking model, which allowed the simulation of tidal currents, wind-driven currents and larval dispersal. Results show: 1) interannual variability of density distribution of larvae; and 2) strong connectivity between commercial shellfish beds and ORE sites. This study shows the importance of ORE site selection in order to: 1) reduce biofouling on ORE infrastructures and 2) develop multi-use platforms at sea to combine needs for ORE and for mariculture.

Full textAbstract:
Odisha’s economy is predominantly agriculture driven. Exports from the mining industries remained a significant source of foreign exchange. However, over a period, aquaculture exports have also emerged as a lucrative possibility. It is a perfectly suitable sector considering the long coastline, rivers and water bodies, and labour intensive nature of the industry. From an individual or community level of operation, aquaculture developed the characteristics of the industry in the early 1970s.
This descriptive research paper investigates the history of the aquaculture industry in Odisha over the past 50 years. The aquaculture industry in Odisha started two decades later than Kerala (another southern state of India), in the form of an experiential learning and opportunity-seeking process by the early players. The subsequent dominance of local players, consolidation, and expansion of the export market proves the natural resource advantage of the State.
The study emphasises the contribution of the sector to the state economy. The adoption of healthy consumption habits, large untapped Indian market, value and values-addition in the product, and evolving traceability requirements for exports are some of the significant challenges facing the industry.
Despite being an important sector for the State, this sector has not received due attention from academic research. Technology adoption practices, productivity improvement, internal competitions, development of industry structure, and role of policy could be some areas for future research.

Aqua feeds have been considered as a major subsector in aquaculture. About 25 commercial fish feed industries in Bangladesh are now formulating over 1 million tones of commercial pelleted feed for the use by aquaculture farmers. A survey of different fish feed industries, their produced feed, used raw materials, machineries, distribution and marketing channel was carried out in 2015 at Noakhali of Bangladesh. Four fish feed industries were found having legal permission to produce fish feed in Noakhali. These were Globe-agro vet Ltd, Partex agro fish feed Ltd, Setu feed mills and R.P (Rasulpur) fish feed Ltd with an area of 9, 3, 2 and 3.5 acre, respectively. They used different types of machineries. Maximum machineries were found in Globe-agro vet Ltd. They used 19 types of raw materials where some were local and some were imported. Maximum raw materials were found in Globe-agro vet Ltd and they used 16 types of raw materials. Four types of fish feed were being produced in four fish feed industries and these are nursery, starter, grower, finisher. Square company was common of different raw materials supplier. Feed companies were linked with other business and take loan from local NGO and foreign organization. Their production capacity was not same rate all round the year. They like to produce feed from March to October. There was not so far difference in proximate composition of surveyed feed industries. Protein ranged at 28-35%, Lipid 5-8 %, moisture 10-12 % and Ash 12-18 %. The government should move forward with financial as well as technical support for the expansion and modernization of fish feed industries with a view to protecting the nature from incursive pollutants generated during feed manufacturing process.Asian J.

Energy facilities and water are inextricably linked. Accordingly, the issue of water quality, its transformation as a result of industrial use of energy facilities and the assessment of further use for aquaculture purposes is an urgent task of our time, especially in relation to weather and climate risks for industries. The article provides a classification of water according to the water supply technology of energy facilities by temperature factor and the possibility of using it for aquaculture tasks. In total, three classes of water are distinguished according to the temperature factor: waters with natural physical and chemical characteristics, where the temperature regime of reservoirs corresponds to the geographical zone in which the reservoir is located (cultivation of fish associated with fish-breeding zone in which the reservoir is located); water of bassin-coolers of energy facilities, characterized by the presence of a zone of increased temperatures as a result of the discharge of heated water (organization of flood-proof farms with polycyclic production); water of cooling ponds (cultivating fish capable to the fight against eutrophication).

The concept of bioeconomics covers all sectors of the economy, including agriculture, which supplies renewable resources: plants, animals, microorganisms and their processed products. The goal is a transition to an economy that is independent of fossil fuels and non-renewable resources. Agriculture and forestry, fisheries and aquaculture, as well as the conversion of biotechnological biomass and biological waste, are central to the multilateral new value chain. The processing industry uses renewable resources in various products, in particular, due to the industrial application of biotechnological and microbiological processes, especially in the chemical industry. This also applies to the food, woodworking, paper, construction, leather, and textile industries, as well as parts of the pharmaceutical and energy industries. Thus, the cyclic system and the storage of reusable waste are also included in the bioeconomic system. The aim of our study is to study the degree of development of sustainable value chains in bioeconomics.

The vast expanse of China’s land surface results in the country’s environment varying from region to region. Environmental changes impact on China’s industries, markets, and trade, indirectly affecting not only the country’s economy but also the people who depend on aquaculture resources. Regional differentiation leads to an imbalance that severely affects social fairness and equity, which becomes a key factor limiting the sustainable development of the economy and society. Analysis and assessment of the changes in environmental factors affecting aquaculture production and fisherfolk’s income in 31 regions of China between 2010 and 2020 aim to provide a reference for regional differentiation in the economic development of aquaculture in the different regions in China, representing an essential step towards achieving the coordinated development of rural regional areas. This study’s assessment and analysis procedures adopted the principal component analysis method. The findings suggest that regional differences in Chinese fisherfolk’s income and the environmental factors affecting China’s aquaculture production are veritable. There have been subtle changes in regional differentiation over a decade. It is necessary to implement contextualized environmental management measures, concessionary taxation, and additional subsidies to address the different characteristics of China’s different regions for the future development of environmental management and narrowing the income gap, to address both the income disparities in Chinese fisherfolk’s income and environmental factors affecting Chinese aquaculture production, to achieve the harmonious development of rural regional areas.

Nanotechnology is a rapidly developing field due to the emergence of various resistant pathogens and the failure of commercial methods of treatment. AgNPs have emerged as one of the best nanotechnology metal nanoparticles due to their large surface-to-volume ratio and success and efficiency in combating various pathogens over the years, with the biological method of synthesis being the most effective and environmentally friendly method. The primary mode of action of AgNPs against pathogens are via their cytotoxicity, which is influenced by the size and shape of the nanoparticles. The cytotoxicity of the AgNPs gives rise to various theorized mechanisms of action of AgNPs against pathogens such as activation of reactive oxygen species, attachment to cellular membranes, intracellular damage and inducing the viable but non-culturable state (VBNC) of pathogens. This review will be centred on the various theorized mechanisms of actions and its application in the aquaculture, livestock and poultry industries. The application of AgNPs in aquaculture is focused around water treatment, disease control and aquatic nutrition, and in the livestock application it is focused on livestock and poultry.

Full textAbstract:
Aquaculture is one of the fastest growing food producing industries in the world. Aquaculture effluent contains high concentrations of inorganic nutrients. Reduction of these inorganic nutrients in aquaculture effluent is crucial for fulfilling the effluent standards or reuse of aquaculture effluent. This study investigated the effective use of green macroalga Caulerpa lentillifera as a bioremediatory species for nutrient removal from aquaculture effluent by conducting an on-station experiment and measurements. The effluent of a fish culture unit was circulated through a macroalgal culture unit every four days for a total of 60 days, allowing 15 circulations. Concentrations of inorganic nutrients (NO2−-N, NO3−-N, NH3-N, and PO43−) were measured in the integrated system consisting of a fish unit, settling unit, macroalgal unit and extra tank for water circulation in triplicates. Multiple linear regression analysis revealed that the application of the bioremediation system led to a significant reduction in nutrient concentrations within one day, and slightly further in the following two days. On average over the 15 circulations, the first one day of application decreased the concentrations of NO2−-N, NO3−-N, NH3-N, and PO43− by 0.247 mg/L, 81.6 mg/L, 0.682 mg/L, and 0.352 mg/L, respectively. Furthermore, the C:N ratio of macroalgae decreased during the 60-day application period, providing evidence of the nutrient uptake by macroalgae. Based on the European Union (EU) standard and quality criteria of France and the Joint FAO/WHO Expert Committee (JFWEC), the macroalgae grown in the integrated system were at the safe level for human consumption in terms of contents of Cd, Pb, and As. The results of our study imply that recirculating aquaculture systems utilizing C. lentillifera for biofiltration have the potential for effective treatment of aquaculture effluent integrating fish and macroalgae production.

Fisheries and aquaculture industry, which provides a continuous and high-return market advantage to potential countries, is also one of the priority industries for Turkey. Although Turkey has important advantages with its geographic position and bio-diversity, the industry's contribution to foreign trade is not at an acceptable level. Accordingly, it is important to evaluate the capture fishery and aquaculture products, which provide the best contribution to the foreign trade of Turkey. Thus, the present paper aims to provide foreign trade executives with an intuition about the most appropriate products to invest in and contributing products to Turkish foreign trade within the scope of market strategies. Entropy-WASPAS, which is a hybrid multi-criteria decision-making method, is used for evaluating the contribution of fishery and aquaculture products to Turkish foreign trade. This model includes both criteria (production, import quantity, import value, export quantity, export value) and alternatives (trout, sea bream, sea bass, sprat, atlantic bonito, anchovy, horse mackerel, pilchard, sea snail, prawn, cuttle fish, mussel). Entropy is used to determine the criteria weights, and WASPAS is applied for ranking the fishery and aquaculture products. According to the results, export value is the most important criteria while Sea Bream is found as the most significant product for Turkey’s foreign trade.

Full textAbstract:
In aquaculture industry, fish, shellfish, and aquatic plants are cultivated in fresh, salt, or brackish waters. The increasing demand of aquatic products has stimulated the rapid growth of aquaculture industries. How to effectively monitor and control water quality is one of the key concerns for aquaculture industry to ensure high productivity and high quality. There are four major categories of water quality concerns that affect aquaculture cultivations, namely, (1) physical parameters, e.g., pH, temperature, dissolved oxygen, and salinity, (2) organic contaminants, (3) biochemical hazards, e.g., cyanotoxins, and (4) biological contaminants, i.e., pathogens. While the physical parameters are affected by climate changes, the latter three are considered as environmental factors. In this review, we provide a comprehensive summary of sensors, biosensors, and analytical technologies available for monitoring aquaculture water quality. They include low-cost commercial sensors and sensor network setups for physical parameters. They also include chromatography, mass spectrometry, biochemistry, and molecular methods (e.g., immunoassays and polymerase chain reaction assays), culture-based method, and biophysical technologies (e.g., biosensors and nanosensors) for environmental contamination factors. According to the different levels of sophistication of various analytical techniques and the information they can provide (either fine fingerprint, highly accurate quantification, semiquantification, qualitative detection, or fast screening), we will comment on how they may be used as complementary tools, as well as their potential and gaps toward current demand of real-time, online, and/or onsite detection.

Full textAbstract:
Irrational and inappropriate use of antibiotics in commercial chicken and aquaculture industries can accelerate the antibiotic resistance process in humans and animals. In Bangladesh, the growing commercial chicken and aquaculture industries are playing significantly important roles in the food value chain. It is necessary to know the antibiotic usage practices and antibiotic resistance in food animal production to design rational policies, guidelines, and interventions. We conducted a narrative review to understand the level of antibiotic usage and resistance in food animal production in Bangladesh. Information about antibiotic usage in different food animal production systems, including commercial chickens and aquaculture in Bangladesh is inadequate. Only a few small-scale studies reported that the majority (up to 100%) of the broiler and layer chicken farms used antibiotics for treating and preventing diseases. However, numerous studies reported antibiotic-resistant bacteria of public health importance in commercial chicken, fish, livestock, and animal origin food. The isolates from different pathogenic bacteria were found resistant against multiple antibiotics, including quinolones, the third or fourth generation of cephalosporins, and polymyxins. Veterinary practitioners empirically treat animals with antibiotics based on presumptive diagnosis due to inadequate microbial diagnostic facilities in Bangladesh. Intensive training is helpful to raise awareness among farmers, feed dealers, and drug sellers on good farming practices, standard biosecurity practices, personal hygiene, and the prudent use of antibiotics. Urgently, the Government of Bangladesh should develop and implement necessary guidelines to mitigate irrational use of antibiotics in food animals using a multi-sectoral One Health approach.

Based on previousweaknesses, the ideal model is the one that reflects an inclusive and holistic manner, suitable forvarious characteristics of industries in each typical areas and people of Indonesia, with the emphasison competitive advantage, untraditional, and commercial basis, especially in respect to thedevelopment of a strong fisheries business. This kind of model should also maintain harmonizedand coordinated programs and actions between involved related institutions. Research supportsare needed to develop and test the most appropriate model. Also, in technical basis, innovationson fish capture, aquaculture, as well as processing technologies are urgently needed as acomplement to the developed model of fisheries industries. One thing that should be kept in mindis the importance of management and conservation of natural resources, including resource forfisheries capture and aquaculture, germ plasms and genetic fish resources, as well as marinemicroorganisms, as these all are the main assets for the development of marine and fisheries inIndonesia.

This study explores the application and critical issues related to the implementation of blockchain technology (BT) to the aquaculture sector, in order to understand the possibilities of improving the relationship with the supply chain and the end consumer, with a view to a sustainability for the marine environment and circular economy. Starting from considerations of commercial and political challenges related to credibility and fairness for all parties involved—from producers, to retailers, to end consumers—the procedure adopted was applied to the case of an Integrated Multi-Trophic Aquaculture project, developed in the sea of Taranto (Italy). Furthermore, it considered two different end markets: the food market for farmed fish and the ornamental fish market for marine aquariums. The results of the study confirm that although the implementation of BT by industries and producers of marine species has the potential to lead to successful sustainability solutions, such adoption is feasible over time only if all actors in the supply chain, from aquaculture companies, to retailers, to consumers, are actively and consciously involved and can access common benefits.

Astaxanthin is a xanthophill pigment with commercial application in the aquaculture, pharmaceutical, food and cosmetic industries. The red yeast Xanthophyllomyces dendrorhous is one of the most promising microorganisms for its industrial production. However, astaxanthin content in wild yeast strains is low. Pigment production by X. dendrorhous can be improved by mutagenesis. The aim of the study was to assess the efficiency of four mutagens: UV radiation, benomyl, ethyl methanesulfonate and ethidium bromide in generating asthaxanthin-hyperproducing strains of the yeast Xanthophyllomyces dendrorhous DSM 5626. Mutations with benomyl, ethidium bromide and UV radiation generated a group of hyperpigmented mutants exhibiting increases up to 100% in astaxanthin content. Ethyl methanesulfonate turned out to be useless in this respect.

The use of marine sponges dates back thousands of years, and interest in these animals is increasing as new applications are discovered. Their potential is extensive, both in their ancient and still popular use as bath sponges for cosmetics and regarding the more recent discovery of bioactive secondary metabolites mainly of interest for the pharmaceutical industry and the less developed aquariology. Despite their proven biofiltration and ecosystem restoration ability and the biomass supply problem for the interested industries, few integrated multi-trophic aquaculture (IMTA) systems incorporate these invertebrates in their facilities. Therefore, in this brief review, the benefits that marine sponges could bring to rapidly growing IMTA systems are summarized, highlighting their suitability for a circular blue economy.

Full textAbstract:
Marine mollusc production contributes to food and economic security worldwide and provides valuable ecological services, yet diseases threaten these industries and wild populations. Although the infrastructure for mollusc aquaculture health management is well characterized, its foundations are not without flaws. Use of notifiable pathogen lists can leave blind spots with regard to detection of unlisted and emerging pathogens. Increased reliance on molecular tools has come without similar attention to diagnostic validation, raising questions about assay performance, and has been accompanied by a reduced emphasis on microscopic diagnostic expertise that could weaken pathogen detection capabilities. Persistent questions concerning pathogen biology and ecology promote regulatory paralysis that impedes trade and which could weaken biosecurity by driving commerce to surreptitious channels. Solutions that might be pursued to improve shellfish aquaculture health management include the establishment of more broad-based surveillance programmes, wider training and use of general methods like histopathology to ensure alertness to emerging diseases, an increased focus on assay assessment and validation as fundamental to assay development, investment in basic research, and application of risk analyses to improve regulation. A continual sharpening of diagnostic tools and approaches and deepening of scientific knowledge is necessary to manage diseases and promote sustainable molluscan shellfish industries.

Full textAbstract:
Most of the fish farmed by small scale Brazilian fish farmers in Brazil is sold directly to local markets without passing through a processing industry. The integration between small-scale fish farmers and the processing industry is restricted to few cooperatives, mainly in the southern region. Although many fish processing plants are operating in different regions, most producers do not have access to them. The lack of integration creates several problems, including low quality of fish due to the absence of sanitary control, informality, impossibility to access supermarkets, and low added value. This paper is based on a case study of aquaculture in the Brazilian state of Tocantins, by using the Global Value Chain approach. The methodology consists of a qualitative process based on face-to-face interviews with value chain agents. The main results indicate that the processing industries are increasing their own production and implementing supply contracts with large producers. More vertical governance is emerging with a high level of control by the industries. Thus, many small-scale fish farmers are being excluded from the value chain.

Atlantic salmon farming is one of the largest aquaculture industries in the world. A major problem in salmon farms is the sea louse ectoparasite Lepeophtheirus salmonis , which can cause stress, secondary infection and sometimes mortality in the salmon host. Sea lice have substantial impacts on farm economics and potentially nearby wild salmonid populations. The most common method of controlling sea louse infestations is application of chemicals. However, most farming regions worldwide have observed resistance to the small set of treatment chemicals that are available. Despite this, there has been little investigation of treatment strategies for managing resistance in aquaculture. In this article, we compare four archetypical treatment strategies inspired by agriculture, where the topic has a rich history of study, and add a fifth strategy common in aquaculture. We use an agent-based model (ABM) to simulate these strategies and their varying applications of chemicals over time and space. We analyse the ABM output to compare how the strategies perform in controlling louse abundance, number of treatments required and levels of resistance in the sea louse population. Our results indicated that among the approaches considered applying chemicals in combination was the most effective over the long term.

Full textAbstract:
Significant challenges to worldwide sustainable food production continue to arise from environmental change and consistent population growth. In order to meet increasing demand, fish production industries are encouraged to maintain high growth densities and to rely on antibiotic intervention throughout all stages of development. The inappropriate administering of antibiotics over time introduces selective pressure, allowing the survival of resistant bacterial strains through adaptive pathways involving transferable nucleotide sequences (i.e., plasmids). This is one of the essential mechanisms of antibiotic resistance development in food production systems. This review article focuses on the main international regulations and governing the administering of antibiotics in finfish husbandry and summarizes recent data regarding the distribution of bacterial resistance in the finfish aquaculture food production chain. The second part of this review examines promising alternative approaches to finfish production, sustainable farming techniques, and vaccination that circumvents excessive antibiotic use, including new animal welfare measures. Then, we reflect on recent adaptations to increasingly interdisciplinary perspectives in the field and their greater alignment with the One Health initiative.

AbstractSeaweed resources play an increasingly important role in European Blue Growth and Bioeconomy strategies and European production is anticipated to increase dramatically with the continued up-swing of global market interests in seaweed resources. As a consequence, there is a need to ensure the environmental sustainability of future aquaculture activities, as reported in the PEGASUS white paper. The present article summarizes the published PEGASUS guidelines developed in the framework of the COST Action Phycomorph, for the future development of this sector. This includes the advances made in this important arena of applied phycology taking into account scientific, technical, environmental, legal and socioeconomic dimensions. Challenges, bottlenecks and risks are identified and presented with a special focus on production issues regarding productivity, breeding, choice of appropriate cultivars, disease and pests and also the risk of using non-indigenous and invasive species as candidates for cultivation. The barriers for long-term, sustainable exploitation are also examined including harmony with the European “Nutrition and Health Regulations” necessary in order to ensure food safety. The PEGASUS guidelines provide scientific recommendations required to address the above issues and to provide science-based advice to policymakers, managers and industries for the sustainable development of industrial-scale seaweed aquaculture in Europe and beyond.

The Tasman Sea has been identified as a climate hotspot and has experienced several marine heatwaves (MHWs) in recent years. These events have impacted coastal regions of New Zealand (NZ), which has had a follow-on effect on local marine and aquaculture industries. Advance warning of extreme marine heat events would enable these industries to mitigate potential losses. Here we present an assessment of the forecast skill of the Australian Bureau of Meteorology’s seasonal prediction system, Australian Community Climate and Earth-System Simulator-Seasonal v1.0 (ACCESS-S1), for three key aquaculture regions around NZ: Hauraki Gulf, Western Cook Strait and Foveaux Strait. We investigate the skill of monthly sea surface temperature anomaly (SSTA) forecasts, and forecasts for SSTA exceeding the 90th percentile, which is an accepted MHW threshold. We find that the model has skill for predicting extreme heat events in all three regions at 0–2 month lead times. We then demonstrate that ACCESS-S1 was able to capture observed monthly SSTA exceeding the 90th percentile around coastal NZ during the 2019 Tasman Sea MHW at a lead time of 1 month. Finally, we discuss the relationship between SSTA in the Tasman Sea and SSTA in coastal regions of NZ, and thus the Tasman Sea as a source of model SSTA skill in the three key coastal regions. Results from this study show that skilful forecasts of ocean heat extremes in regional areas have the potential to enable marine operators in the aquaclture industry to mitigate losses due to MHWs, especially in a warming climate.

La zona costera del Noroeste de México cuenta con una gran cantidad de lagunas costeras, con características y condiciones favorables para el desarrollo de la industria de la acuacultura. Actualmente, el cultivo de camarón es una de las industrias con mayor crecimiento en el mundo. Esta industria ha tenido un crecimiento acelerado en Norte y Sudamérica, y particularmente en México en el Golfo de California. En 2010, 70.3% de la producción acuícola de México provino del litoral del Golfo de California, de la cual 97.7% fue de granjas de camarón. Sin embargo, se han documentado diversos efectos adversos de la acuacultura: conflicto con otras actividades económicas (por ejemplo agricultura, pesquerías y turismo), el cambio de uso de suelo, la deforestación de manglares y diferentes tipos de contaminación (principalmente asociada a la descarga y filtración de materia orgánica). Los isótopos estables de C y N son una valiosa herramienta para detectar los posibles impactos de la acuacultura en los ecosistemas, ya que ayudan a determinar la dinámica de la materia orgánica descargada y/o filtrada a los ecosistemas marinos. Estos estudios permiten evaluar y planear el desarrollo sustentable de la acuacultura. Este enfoque se relaciona con el uso de los fundamentos de la eco-tecnología, los cuales buscan la auto-regulación y el auto-mantenimiento de los ecosistemas, causando alteraciones ecológicas mínimas. ABSTRACTThe coastal zone of Northwest of Mexico has many coastal lagoons with characteristics and conditions for the development of aquaculture industry. Actually, shrimp aquaculture is one of the industries with the major development in the world. This industry has had an accelerate growth in North and South America, and in México, particularly around the Gulf of California. In 2010, around 70.3% of the aquaculture production came from the Gulf of California littoral, and 97.7% of this total was from shrimp farms. However, there are documented many adverse effects associated to aquaculture: conflicts with other activities (e.g. agriculture, fisheries and tourism), change of use of land, mangrove deforestation and different types of pollution (mainly associated to discharge and filtration of residual organic matter). The stable isotopes of C and N areis a valuable tool in studies to detect the possible impacts of aquaculture on ecosystems, because help to determine the dynamic of organic matter discharged and/or filtered to marine environments. These studies allow evaluate and plan the sustainable development of aquaculture. This approach is related to eco-technology fundaments which seeks auto-regulation and auto-maintenance of ecosystems, causing minimal ecological disruption.
