Resumen

In the article, the global tendencies in healthy food on the basis of nutrition pyramids are considered. The revealed tendencies as well as an analysis of fish materials classification on fat and protein content allowed to develop a scheme named "The fish products guide". Such guide will allow to create a nutrition system individually and to strengthen the demand for fish products.

Resumen

As a result of the analysis of domestic experience over the past 10 years and foreign experience (on the example of 9 countries: Vietnam, India, Spain, Canada, China, Norway, the USA, Chile, Japan, which possess the most advanced technologies and equipment for the production of highly effective feed for fish ) in the development of innovative technologies and equipment for the production of highly effective feed for fish, it was found out that the methods of both dry and wet pressing are outdated and do not meet modern requirements for the production of feed for fish, as they do not allow to carry out deep physicochemical transformations in the protein-carbohydrate complex and to introduce fat components at 40% level. Modern fish technologies are based on the use of extrusion processing of a multicomponent mixture to impart different buoyancy and adjustable immersion speed of the resulting feed. Extrusion technology will allow to introduce a large amount of fat into the product - up to 35–40%, to achieve 100% starch cleavage level. Extruded product has high water resistance, keeps its shape. New generation developed compound feed formulations for tilapia with 60% protein content, 40% fat, with the introduction of growth stimulants, dietary supplements, etc., will increase the digestibility of compound feed by fish by 10-12%, increase of fish weight by 10-12%, reduce the cost of commercial fish farming by 10–15%, reduce feed conversion by 15%. The proposed technology will allow to create new generation compound feeds formulations for various fish species with a high content of protein-fat complex, which will increase the weight gain of fish by 12-17%, reduce the cost of final fish production by reducing the cost of feed by 10-15%. .

Resumen

This study was undertaken to investigate the suitability of using fish market wastes (viscera) as raw material for powder fish silage production. Fish viscera contained 14.01±0.68% protein, 20.00±1.04% lipid, 4.75±0.64% ash, 60.62±2.15% moisture and 0.62±0.08% Nitrogen Free Extract (NFE). The pH of fish viscera was 6.21±0.07. For liquid fish silage production, 2, 3, 4 and 5% formic acid were added in blended viscera, of which 4% formic acid was found better that had a pH value of 3.77±0.07. Liquid silage contained 12.00±0.89% protein, 17.26±1.49% lipid, 3.73±0.81% ash, 66.41±3.07% moisture and 0.60±0.09% NFE. For neutralizing liquid fish silage, various concentrations, viz. 1, 2, 3, 4, 5 and 6% Na2CO3 were added. The pH value (6.32±0.01) was better when mixing with 4% Na2CO3. To produce powder fish silage 20, 30, 40 and 50% rice bran were mixed in liquid fish silage. Powder silage made with 30% rice bran was found better to improve the nutritional quality of the product that contained 20.84±0.12% protein, 33.73±0.14% lipid, 14.05±0.27% ash, 10.83±0.19% moisture, 6.61±0.10% crude fiber and 13.94% carbohydrate. The pH value was 6.54±0.01. After preparation, powder fish silage was packaged. The packaged powder fish silage was then stored for 4 months at room temperature (20-300C). After four months of storage, the contents of protein, lipid, ash, moisture, crude fiber, carbohydrate and pH reached at 20.30±0.13, 32.41±0.16, 13.49±0.33, 10.98±0.28, 6.32±0.07, 16.50% and 6.76±0.09, respectively. It was found that nutritional value of powder fish silage was very high and can be used in fish feed to reduce feed cost and enhance aquaculture production.SAARC J. Agri., 13(2): 13-25 (2015)

Resumen

The present research work was conducted from July 2008 to June 2009 to investigate intensity of infestation of parasites in freshwater fishes and the impact of fish diseases on fish production in northern region of Bangladesh. Possibility of out break of diseases due to deterioration of environmental factors of water bodies was included in this study. The diseases identified were ulcer diseases, EUS (Epizootic Ulcerative Syndrome), Ichthyophthiriasis, Trichodiniasis, Chilodoneliasis, Myxoboliasis, Dactylogyrosis, Gyrodactylosis, Argulosis, Pernicious anaemia, Red spot disease, Red Pest of freshwater eel, Mouth fungus, Branchiomysis, Abdominal dropsy and whirling disease. The infestation more occurred in young fishes than in adult fishes. The overall water qualities of water bodies fluctuated from July 2008 to June 2009. Physicochemical parameters have more or less significant combined effect on the deterioration of water quality as well as fish diseases. Gills were the most affected sites and parasites damaged gill filaments by rupturing blood capillaries, causing necrosis, coagulation and hemorrhage. The present study revealed the prevalence of different organisms in fishes, which are potential pathogen for them. Fishes were infested by parasites and other pathogens. From overall study it was observed that the parasites, bacteria and fungus were most important pathogen for outbreak of diseases. It was also observed that there was a direct relation between disease outbreak among fishes and environmental factors. Low alkalinity reduces the buffer capacity of water and badly affects the pond ecosystem, which in turn cause stress to the fish and become more susceptible to diseases. In case of low aquatic environmental temperature fish reduces metabolic activities, which in turn makes the fish more susceptible during the winter period towards parasitic infection.

Resumen

In order to decrease the pollution of the marine environment from dumping fish waste and by-catch, alternative use for co-digestion with sludge in anaerobic condition was studied. The purpose of this project is to optimize the methane potential from adjustment of the proportion among mixed substrates. Ten groups of different proportions among fish waste, by-catch and sludge were conducted with AMPTS II instrument under mesophilic condition (37 ± 0.5 ºC), by means of the principle of BMP test. The ratio of inoculums and mixed substrate was set as 3:2. The optimal MP obtained after an experiment with 13 days digestion was 0.533 Nm3 CH4/kg VS from the composition of sludge, by-catch and fish waste as 33 %, 45 % and 22 %. It was improved by 6 % and 25.6 %, to compare with the previous studies by Almkvist (2012) and Tomczak-Wandzel (personal communication, February 2012) respectively.

Resumen

The role of autotrophic production in different coastal habitats in the production of fish in estuaries is an important consideration in coastal management and conservation. In the estuarine waters of the Australian east coast, many economically important fish species occur over mudflats lacking conspicuous vegetation. I used stable isotope analysis to examine where such fish ultimately derived their nutrition, in the subtropical waters of southern Moreton Bay, Queensland, Australia. I first tested traditional processing methodologies of autotroph samples, in this case of mangrove leaves, and examined variability in mangrove isotope values at different spatial scales. Mangrove leaves processed using time-consuming grinding showed no significant difference in isotope values than coarsely broken leaf fragments. Isotope values of green leaves were not meaningfully different from yellow or brown leaves that would normally be the leaves that actually dropped on to the sediment. Future analyses therefore can use green leaves, since they are more abundant and therefore more easily collected, and can simply be processed as whole leaf fragments rather than being ground to a powder. Carbon and nitrogen isotope values varied at several spatial scales. The proportion of variability partitioned at different scales varied depending on the species of mangrove and element (C or N) analysed. To properly represent a geographic area, isotope analysis should be done on leaves collected at different locations and, especially, from different trees within locations. The autotrophic source(s) supporting food webs leading to fish production on mudflats might be either in situ microphytobenthos or material transported from adjacent habitats dominated by macrophytes. I tested the importance of these sources by measuring ?13C values of 22 fish species and six autotroph taxa (microphytobenthos on mudflats, and seagrass, seagrass epiphytic algae, mangroves, saltmarsh succulents and saltmarsh grass in adjacent habitats) in Moreton Bay. I calculated the distribution of feasible contributions of each autotroph to fishes. All fish ?13C values lay in the enriched half of the range for autotrophs. For over 90% of fishes, the top three contributing autotrophs were seagrass, epiphytes and saltmarsh grass, with median estimates of approximately 60-90% from these sources combined. Seagrass was typically ranked as the main contributor based on medians, while epiphytic algae stood out based on 75th percentile contributions. The other three sources, including MPB, were ranked in the top three contributors for only a single fish. Organic matter from seagrass meadows is clearly important at the base of food webs for fish on adjacent unvegetated mudflats, either through outwelling of particular organic matter or via a series of predator-prey interactions (trophic relay). Modelling results indicate that saltmarsh grass (Sporobolus) also had high contributions for many fish species, but this is probably a spurious result, reflecting the similarity in isotope values of this autotroph to seagrass. Carbon from adjacent habitats and not in situ microphytobenthos dominates the nutrition for this suite of 22 fishes caught over mudflats. The ultimate autotrophic sources supporting production of three commercially important fish species from Moreton Bay were re-examined by further analysing carbon and nitrogen stable isotope data. Mean isotope values over the whole estuary for fish and autotroph sources were again modelled to indicate feasible combinations of sources. Variability in isotope values among nine locations (separated by 3-10 km) was then used as a further test of the likelihood that sources were involved in fish nutrition. A positive spatial correlation between isotope values of a fish species and an autotroph indicates a substantial contribution from the autotroph. Spatial correlations were tested with a newly developed randomisation procedure using differences between fish and autotroph values at each location, based on carbon and nitrogen isotopes combined in two-dimensional space. Both whole estuary modelling and spatial analysis showed that seagrass, epiphytic algae and particulate organic matter in the water column, potentially including phytoplankton, are likely contributors to bream (Acanthopagrus australis) nutrition. However, spatial analysis also showed that mangroves were involved (up to 33% contribution), despite a very low contribution based on whole estuary modelling. Spatial analysis for sand whiting (Sillago ciliata) demonstrated the importance of two sources, mangroves and microalgae on the mudflats, considered unimportant based on whole estuary modelling. No spatial correlations were found between winter whiting (Sillago maculata) and autotrophs, either because fish moved among locations or relied on different autotrophs at different locations. Spatial correlations between consumer and source isotope values provide a useful analytical tool for identifying the role of autotrophs in foodwebs, and were used here to demonstrate that organic matter from adjacent habitats, and in some cases also in situ production of microalgae, were important to fish over mudflats. Whilst recognising that production from several habitats is implicated in the nutrition of fishes over mudflats in Moreton Bay, clearly the major source is from seagrass meadows. Organic matter deriving from seagrass itself and/or algae epiphytic on seagrass is the most important source at the base of fisheries food webs in Moreton Bay. The importance of seagrass and its epiphytic algae to production of fisheries species in Moreton Bay reinforces the need to conserve and protect seagrass meadows from adverse anthropogenic influences.

Resumen

The major toxins and pathogens in fish meal were investigated because of food industry, public and animal health concerns. The effect of processing, the type of raw material used and storage conditions on the main toxin, histamine which causes gizzard erosion in poultry, and its formation in fish meal were investigated. The results showed that histamine and histamine-like amines in fish meal varied in levels between batches depending on the quality of raw material and type of fish used. The relationship between histamine and histamine-like amines levels was unclear. During laboratory processing of fish meal it was found that most histamine concentrated in the stickwater which had implications for the use of stickwater meal in feeds. Interestingly, histamine was detected in the stickwater meal of cod as well as mackerel. A decrease in histamine in mackerel meal and cod meal during processing was observed with respect to levels in raw material. The decrease maybe originated after the cooking stage especially in the stickwater meal (probably due to bacterial recontamination or enzymatic reactions). The decrease could be due to histamine either adhering to the equipment used or breakdown to its metabolites or derivitising to gizzerosine. Since very low levels of histamine were observed from meals produced from reasonably fresh fish, the control of histamine therefore is best achieved at the raw material stage of production. During storage trials, there was no increase in histamine levels but a decrease occurred gradually with time at 15°C, 70% RH. Rapid loss occurred at 25 and 30°C, 80% RH and heavy mould growth was also observed, although no mycotoxins were detected in analysed samples. Routine analytical methods were studied and compared for the requirements of the fish meal industry and poultry farmers. Problems occurred with the colorimetric method when applied to fish meal and fish samples containing bones due to the presence of calcium. It was modified for routine histamine analysis. Thin Layer Chromatography was the second alternative. Although High Performance Liquid Chromatography was suitable for analysing histamine and histamine-like amines together, it did lack in meeting industrial requirements. Since the modified colorirnetric method was labour intensive, despite its other advantages, there was still a need for a simpler and quicker method of analysis. For this reason, research work was carried out to develop an immunoassay for histamine analysis. The results showed that it was possible to raise antibody against histamine and suggested future research potential. Hygienic conditions of laboratory scale fish meal production were investigated. The presence of Salmonella, which leads to human salmonellosis, and E. coli 0157:H7 which also cause human food poisoning were studied. The results showed that the critical control point of fish meal production was after cooking, since recontamination can occur. Salmonella was present in several batches of commercial and laboratory processed samples, but no E. coli 0157:H7 was detected in analysed samples. Three rapid methods were compared to traditional method for Salmonella analysis particularly in fish meal. The immunoassay method introduced by Institute of Food Research, Norwich was found the most suitable because it was sensitive, specific and took about one day to complete.

The preparation of fish protein hydrolysates by a fermentative process is an alternative to classical preparation using added proteolytic enzymes, taking advantage of the wide spectrum of proteolytic enzymes produced by microorganisms and increasing the complexity of the peptide mixture obtained. Thus, the objective of this work was to prepare fermentative protein hydrolysates (FPH) from a commercial cod protein hydrolysate (CPH) using an indigenous marine proteolytic strain. The bacterial growth was performed in liquid culture media, containing three concentrations of CPH (1, 2 and 4%), yeast extract (0.5%) and sucrose (0.5%), with continuous shaking, at 30 ºC for 24, 50 and 72 hours. The parameters evaluated were the culture growth, enzymatic activity, protein content and recovery, peptide profile, degree of hydrolysis and antioxidant activity, measured by DPPH and ABTS radical scavenging activity, reducing power and metal chelating activity. Bacterial growth and enzymatic activity reached their maximums after 24 hours of fermentation, and all FPH showed the disappearance of peptides in the range of 200 – 400 Da. In the set of samples, 4 % FPH recorded the highest values of protein content and recovery, but 1 % and 2 % FPH were the samples that presented improved antioxidant activity.

Resumen

In the past, oceans have strongly influenced atmospheric CO2 levels through organic and inorganic carbon cycling. The inorganic carbon pump relies on the formation of calcium carbonate which releases CO2 into the surface ocean and traps alkalinity in solid form which sinks to deeper ocean layers and sediments. After sinking, calcium carbonate can either then become trapped in the sediments or dissolve increasing the alkalinity of deeper ocean layers. The net effect is of acidifying surface oceans and encouraging release of CO2 to the atmosphere. The present thesis focuses on marine teleost (bony) fish in temperate areas as previously poorly understood but potentially major producers of calcium carbonate in the ocean. Fish in temperate areas may be contributing to carbonate sediment production and as such the inorganic carbon pump. Prior to this thesis only tropical fish have been investigated as major piscine sediment producers. The present thesis describes the composition and morphology of carbonates produced by many different species of temperate fish providing a basis for the understanding the fate of these carbonates in the environments and their potential contribution to sediment production and the inorganic carbon cycle. Characteristics of carbonates produced by fish in the wild were fairly consistent within a species upon examination of carbonates produced by poor cod (Trisopterus minutus) over the course of a year. However, despite the likely consistent and distinct characteristics of fish carbonates, little evidence of them was found in temperate shallow sediments beneath pens of farmed Atlantic salmon (Salmo salar) where there theoretically should be very high production rates. Reduced salinity, often a feature of temperate areas compared to tropical areas, was found to reduce production rates of carbonate from fish compared to higher salinities. However, salinity reductions below the ocean average of 35 psu (practical salinity units) had less impact on production rates than increases above 35 psu. As such it is argued that production rates in temperate environments should still be relatively high considering high fish biomasses in some temperate regions and could still mean fish in temperate areas are an important source of carbonate production and potential sediment production.

Resumen

Ongoing climate change is predicted to increase water temperatures and export of terrestrial dissolved matter (TDOM) to aquatic ecosystems influencing ecosystem productivity, food web dynamics and production of top consumers. Ecosystem productivity is mainly determined by the rates of primary production (GPP) in turn controlled by nutrients, light availability and temperature, while temperature alone affect vital rates like consumption and metabolic rates and maintenance requirements of consumers. Increased level of TDOM causes brownification of water which may cause light limitation in algae and decrease GPP and especially so in the benthic habitat. Temperature increase has a been suggested to increase metabolic rates of consumers to larger extent than the corresponding effect on GPP, which suggest reduced top consumer biomass and production with warming. The aim of this thesis was to experimentally study the effects of increased temperature and TDOM on habitat specific and whole ecosystem GPP and fish densities and production. In a replicated large-scale pond experiment encompassing natural food webs of lotic ecosystems I studied population level responses to warming and brownification in the three- spined stickleback (Gasterosteus aculeatus). Results showed overall that warming had no effect on whole ecosystem GPP, likely due to nutrient limitation, while TDOM input decreased benthic GPP but stimulated pelagic GPP. In fish, results first of all suggested that recruitment in sticklebacks over summer was negatively affected by warming as maintenance requirements in relation to GPP increased and thereby increased starvation mortality of young-of-the-year (YOY) sticklebacks. Secondly, brownification increased mortality over winter in YOY as the negative effect on light conditions likely decreased search efficiency and caused lower consumption rates and starvation over winter in sticklebacks. Third, seasonal production of YOY, older, and total stickleback production was negatively affected by warming, while increased TDOM caused decreased YOY and total fish production. The combined effect of the two was intermediate but still negative. Temperature effects on fish production were likely a result of increased energy requirements of fish in relation to resource production and intake rates whereas the negative effect of TDOM likely was a result of decreased benthic resource production. Finally, effects of warming over a three-year period caused total fish density and biomass and abundance of both mature and old fish to decrease, while proportion of young fish increased. The main cause behind the strong negative effects of warming on fish population biomass and changes in population demographic parameters were likely the temperature driven increased energy requirements relative to resource production and cohort competition. The results from this thesis suggest that predicted climate change impacts on lentic aquatic ecosystems will decrease future densities and biomass of fish and negatively affect fish production and especially so in systems dominated by benthic resource production.

Resumen

AbstractFish and feed waste provide most of the nutrients required by the plants in aquaponics if the optimum ratio between daily fish feed inputs and the plant growing area is sustained. Thus, the fish feed needs to fulfil both the fish’s and plant’s nutritional requirements in an aquaponic system. A controlled fish waste production strategy where the nitrogen, phosphorus and mineral contents of fish diets are manipulated and used provides a way of influencing the rates of accumulation of nutrients, thereby reducing the need for the additional supplementation of nutrients. To optimize the performance and cost-effectiveness of aquaponic production, fish diets and feeding schedules should be designed carefully to provide nutrients at the right level and time to complement fish, bacteria and plants. To achieve this, a species-specific tailor-made aquaponic feed may be optimized to suit the aquaponic system as a whole. The optimal point would be determined based on overall system performance parameters, including economic and environmental sustainability measures. This chapter thus focuses on fish diets and feed and reviews the state of the art in fish diets, ingredients and additives, as well as the nutritional/sustainable challenges that need to be considered when producing specific aquaponic feeds.

Resumen

The secondary raw materials of fish can be used for various purposes in food industry, agriculture, etc. No less important way for usage of secondary raw fish, dead fish and fish farming sludge is the utilization of mentioned feedstocks for energy purposes, i.e. biofuels production. In this reearch, the possibilities of the consumption of dead fish and fish farming sludge for biodiesel and biogas production has been studied. The influence of the basic biodiesel production parameters, including the methanol to oil molar ratio, amount of catalyst, temperature and process duration on transesterification yield was determined. The guantitative and gualitative research of biogas production using different substrates such as fish waste, fish farming sludge and substrates composed of fish waste (de-oiled and non de-oiled biomass)+fish farming sludge and fish farming sludge+wastewater sludge was performed. The biodiesel yield higher than 96.5% could be achieved under the following process conditions: methanol/oil molar ratio – 4:1, amount of enzyme content – 7% from oil mass, temperature – 40 ° C, reaction time – 24 hours. The highest biogas yield (1224 ml/gVS) was determined using wet fish waste biomass and mixed substrates consisted of fish waste and fish farming sludge. The results of qualitative biogas research revealed, that biogas produced from both homogeneous and heterogeneous substrates contained more than 60% of methane. The highest calorific value (app. 70% of methane) had biogas gained from fish waste biomass.

Resumen

Aquaponics is an eco-friendly system for food production utilizing aquaculture and hydroponics to cultivate fish and crop without soil. It is an inexpensive symbiotic cycle between the fish and plant. In an aquaponic system, fish waste (ammonia) is fed into the plant bed which acts as a bio-filter and takes the nitrate which is essential to grow vegetation. The fresh new water is then returned to the fish enclosure to restart the cycle. A unique advantage of an aquaponic system is conserving water more effectively compared to traditional irrigation systems. Conservation of water is accomplished by recirculating water between the plant bed and the fish habitat continuously. Organic fertilization of plants using dissolved fish waste is the other benefit of aquaponics. Utilizing plants as a natural alternative to other filters, requires less monitoring of water quality. In our project, an aquaponics system was designed and built in Lyle Center for Regenerative Studies at California State Polytechnic University of Pomona. The future purpose of our project is finding an optimized situation for the aquaponics system to produce food and save water more efficiently and eco-friendly.

Resumen

EU countries have agreed on GREEN DEAL and have committed to achieve carbon neutrality by 2050. Very important role for achieving the goal is playing production and manufacturing industry. This article is devoted to fish production industry, which is as subdivision of food production industry. During past decades the amount of fish caught has increased multiple times. Fishing industry nowadays is being strongly regulated and monitored by various institutions including. Which sets environmental legislation for controlling and improving industries impact (energy efficiency, pollution, waste) on the habitat and environment. For EU to make right decisions on how the member states could develop their fish production industry, it is necessary to have overall evaluation which includes the development opportunities. The efficiency of the fish production company characterizes the amount of resources used, as well as energy efficiency, water usage, the possibility to implement of circular economy, and other criteria which must be evaluated from the perspective if environmental, engineering, economic and social aspects. The fish production company analysis in this article are analysed using Data envelopement analysis (DEA) multicriteria analysis. First results show that fish manufacturers must pay attention to the technological processes in order to move towards carbon neutral society.

Resumen

Objectives: To accomplish stable expression, inheritance of transgenes and growth improvement in transgenic channel catfish, Ictalurus punctatus, and common carp, Cyprinus carpio, containing growth hormone (GH) genes, develop transgenic fish with all fish constructs, determine the relationships between copy number, expression and growth, determine the combined affect of selective breeding and gene transfer and assess environmental risk of transgenic fish. To develop mechanisms of triploidization for transgenic carp. Results: Performance of transgenic channel catfish was made uniform by selection. Growth of channel catfish and common carp was improved 40-50% more by combining gene transfer of GH genes with selection and crossbreeding than with either selection of crossbreeding. Growth improvement of transgenic catfish was not strongly correlated with copy number and expression levels. Progress was made in producting triploid transgenic common carp. Insertion of salmonid GH gene did not alter reproductive performance in channel catfish. Transgenic channel catfish grew no faster than controls when they had to forage on natural food and transgenic individuals were slightly more vulnerable to predation indicating that fitness of transgenic individuals in natural conditions is less than or equal to non-transgenic channel catfish. Contribution to Agriculture: These experiments are the first to demonstrate that transgenic fish can increase aquaculture production in the aquaculture production in the aquaculture environment. This research also demonstrated that maximum benefit of gene transfer in farmed fish is attained when combined with traditional selective breeding.

Resumen

The FAO has projected a doubling in world demand for seafood during the 21 ed from aquaculture of marine fish and shrimps fed primarily on fishmeal-based aquafeeds. However, current practices of high intensity monoculture of shrimp in coastal ponds and fish in offshore pens have been strongly criticized as being ecologically and socially unsustainable. This view derives from un- checked eutrophication of coastal marine ecosystems from fish farm effluents, and the destruction of coastal estuarine ecosystems by shrimp farm constructions, plus aquaculture’s reliance on wild-caught small fish - which are excellent food for humans, but instead are rendered into fishmeal and fish oil for formulating aquafeeds. Fishmeal-sparing and waste- reduction aquafeeds can only delay the time when fed aquaculture product are priced out of affordability for most consumers. Additionally, replacement of fishmeal protein and fish oil by terrestrial plant sources such as soybean meal and oil directly raises food costs for human communities in developing nations. New formulations incorporating sustainably-produced marine algal proteins and oils are growing in acceptance as viable and practical alternatives. This BARD collaborative research project investigated a sustainable water-sparing spray/drip culture method for producing high-protein marine macrophyte meals for incorporation into marine shrimp and fish diets. The spray culture work was conducted at laboratory-scale in the USA (UCSD-SIO) using selected Gracilariaand Ulvastrains isolated and supplied by UCONN, and outdoors at pilot-scale in Israel (IOLR-NCM) using local strains of Ulvasp., and nitrogen/phosphorus-enriched fish farm effluent to fertilize the spray cultures and produce seaweed biomass and meals containing up to 27% raw protein (dry weight content). Auburn University (USA) in consultation with TAMUS (USA) used the IOLR meals to formulate diets and conduct marine shrimp feeding trials, which resulted in mixed outcomes, indicating further work was needed to chemically identify and remove anti-nutritional elements present in the IOLR-produced seaweed meals.
