Tujuan tulisan ini memaparkan hasil identifikasi dan potensi pemanfaatan limbah perikanan di Banda Aceh. Hasil kajian menunjukkan bahwa limbah yang dihasilkan dari usaha perikanan (penangkapan, budidaya, pengolahan) dan usaha non-perikanan sebagian besar belum dimanfaatkan secara optimal. Limbah yang dihasilkan dari usaha penangkapan adalah limbah padat berupa sisa ikan hasil pembongkaran dengan status sudah dimanfaatkan untuk pakan unggas. Limbah dari usaha pengolahan antara lain limbah padat berupa sisa ikan bagian kepala, isi perut dan tulang dengan status belum dimanfaatkan karena terbatasnya pengetahuan dan keterampilan dalam mengadopsi teknologi. Limbah dari usaha budidaya berupa padatan yang sudah dimanfaatkan sebagai pupuk kompos, sedangkan limbah dari budidaya kepiting soka belum dimanfaatkan. Jenis usaha yang berpotensi untuk dikembangkan dengan memanfaatkan limbah tersebut adalah: 1) usaha tepung ikan; 2) usaha pembuatan pakan ikan dan unggas; 3) usaha olahan makanan ringan (snack) tulang ikan; 4) usaha kerajinan aksesoris berupa tas atau dompet; 5) usaha pembuatan tepung bahan baku citosan.Title: Potential Use of Fisheries Waste in Banda AcehThis paper aimed to describe the identification of fisheries waste management in Banda Aceh. Results showed that waste from fisheries (catching, aquaculture, fish processing) and non-fisheries activities largely untapped optimally. Solid waste from marine captured fisheries is demolition of the remaining fish with status already used for poultry feed. Waste from processing businesses include solid waste such as leftover fish head, entrails and bone status untapped due to limited knowledge and skills in adopting technology. Waste from aguaculture in the form of solids that have been used as compost, while soft-shelled crab waste from aquaculture untapped. Type of business which have potential to be developed by utilizing the waste are: 1) business of fish meal; 2) business of making fish feed and poultry; 3) business of processed snack fish bone; 4) craft business accessories such as handbags or wallets; 5) business of making starch feedstock citosan.

Energy is a very fundamental necessity in human life. Current energy usage is highly dependent on the surrounding environment. Especially in remote areas, which require simple energy instruments such as batteries or fuel cells. The Fuel cell is an energy instrument that transfers electricity from a rechargeable source using external materials. Microbial Fuel Cell (MFC) is an alternative form of environmentally friendly energy that is commonly used as a source of energy in the future. MFC is an energy instrument that can convert chemical energy into electrical energy through catalytic reactions by utilizing microorganisms. Plant waste tofu and fishery waste is a waste that contains a lot of carbohydrates, proteins, and fats that usually cause heavy pollution to the waters. By utilizing the liquid waste itself is one way of solving problems in the environment and lack of energy by using the MFC system. For the experiment, this time aimed to compare the electrical energy generated between waste plant tofu and sewage fisheries. In a strong MFC experiment current on plant waste knows an increase as much as 1.47% of fisheries waste, while for voltages in the trial MFC waste fisheries have increased by 1.19% from tofu plant waste.

Abstract Chlorella sp. can growth in various media that contains enough nutrients, such as N, P, K and other micro-elements. Growth of Chlorella sp. requires the availability of nutrients that can be derived from the chemical decomposition and solution results or waste. Liquid fertilizer waste sardinella fish (Sardinella sp.) is wasted and without any economic value is a new breakthrough in utilizing any part in the fisheries sector so as to maximize the potential of fisheries. Utilization of this, one of which is to make Liquid fertilizer waste sardinella fish (Sardinella sp.) which serve as nutrients for the growth of Chlorella sp. with 7 treatments and repeated 3 times. The treatment used is the doses of liquid fertilizer waste sardinella fish (Sardinella sp.) differently, namely A (0,25 ml/L), B (0,5 ml/L), C (1,75 ml/L), D (1 ml/L), E (1,25 ml/L), F (1,5 ml/L), G (Walne), H (without fertilizer). The results showed that the addition of liquid fertilizer waste sardinella fish (Sardinella sp.) with different doses give a real impact (p<0,05) for growth population of Chlorella sp. The best doses of liquid fertilizer waste sardinella fish (Sardinella sp.) for the population growth rate of Chlorella sp. was 0.75 ml / L is the treatment of C with the highest population of 3500x103 cells / ml.

Fisheries management has evolved in Malawi from a traditional system to a centralized regime and lately to co-management fisheries systems, although, success stories about sustainability of the fishery resources are few. Open access nature of fisheries resources has posed a challenge to management regimes. Resource over exploitation has continued in a majority of fisheries worsened by large stretches of the shoreline manned by a single fisheries field staff, and limited capacity by DoF to monitor and manage the fishery. However, isolated localities have upheld management styles that have facilitated sustainable exploitation. Mbenji Island fishery ‘managers’ have ensured high compliance to fisheries rules and regulations among fishers through strict enforcement and maintained abundant fish stocks amid visibly declining levels of fish in vast localities of Lake Malawi and other water bodies in Malawi. There is,therefore, need to take the Mbenji Island success story to other fishing communities to learn from their fisheries management strategies. Information Communication Technology (ICT) as a powerful means in mobilizing communities to take charge of their own development should support ‘best practices’ and offer fishing communities access to the same type of services and advantages. If appropriately applied,ICT can provide for real-time monitoring of fisheries resources as fishers alarm law enforcers to move in at appropriate times. Fishers also strike deals on mobile phones for the day's catch even before landing at shore. This reduces post-harvest waste from delayed handling of fish. Computers have been used for data management, storage and analysis as well as accessing internet services. Studies have shown commonalities in fisher communities in terms of socio-economic and cultural characteristics. On the basis of such an advantage, more could be shared among such communities. Management success can be adopted by other communities of fishers through use of ICT such as radio programs (supplemented by phone-in sessions) undertaken by local-level resource users. These programs provide locally available information and knowledge on best practices aimed at sustainability with means within communities. This encourages community members in other localities to come together to seek the way forward on the basis of lessons from successful communities aired on local radio stations (both community or national radio stations). It is easier to adopt practices that have worked in near vicinities. After all,what is currently called co-management is seemingly based on indigenous knowledge of fishers and other resource users. Mbenji Island is one of the custodians of ICT option in small-scale fisheries management of Lake Malawi. Information Communication Technology provides opportunity for both the Malawi Department of Fisheries (DoF) and fishers with information about fisher community activities including catch and market regardless of distance.

In recent years, the problem of food waste has attracted considerable interest from food producers, processors, retailers, and consumers alike. Food waste is considered not only a sustainability problem related to food security, but also an economic problem since it directly impacts the profitability of the whole food supply chain. In developed countries, consumers are one of the main contributors to food waste and ultimately pay for all wastes produced throughout the food supply chain. To secure food and reduce food waste, it is essential to have a comprehensive understanding of the various sources of food wastes throughout the food supply chain. The present review examines various reports currently in the literature and quantifies waste levels and examines the trends in wastage for various food sectors such as fruit and vegetable, fisheries, meat and poultry, grain, milk, and dairy. Factors contributing to food waste, effective cost/benefit food waste utilisation methods, sustainability and environment considerations, and public acceptance are identified as hurdles in preventing large-scale food waste processing. Thus, we highlight the need for further research to identify and report food waste so that government regulators and food supply chain stakeholders can actively develop effective waste utilisation practices.

Critical land area in Indonesia was recorded 23.25 million ha in 2000, and increased to 77.8 million ha in 2007, efforts are needed to optimize it. However, the existence of agricultural waste, livestock waste and sewage abundant fishery potential to increase soil fertility has not been utilized to the maximum. This study aimed to determine the macro nutrient content available in waste after the fermentation process. This research is an experimental research conducted in a laboratory to find out the content of: N, P, K, C / N ratio. The method for making liquid organic fertilizer is fermentation for one month using EM4 effective microorganisms, then analyzed using Spectrometry and Titrimetry Kjeldahl. The results showed that the highest N content was in bio urine fermentation (0.126%), fish waste (0.035%) and mixed waste (0.028%); The highest P was found in cattle rumen (7.239 mg / L), bio urine (5.234 mg / L), and seaweed (4.689 mg / L), and highest K was found in fruit waste (7, 801 mg / L). The highest C / N ratio was found in seaweed (55,643%) and fruit waste (27,857%). The conclusion is that agricultural waste, livestock waste, and fisheries waste after 1 month of fermentation contain adequate nutrients for optimizing critical land.

Abstract Frid, C. L. J., and Paramor, O. A. L. 2012. Feeding the world: what role for fisheries? – ICES Journal of Marine Science, 69: 145–150. Fisheries (wild capture and aquaculture) deliver more than 110 million tonnes of food and around 15% of the dietary protein to the 7 billion people currently living on the planet. With the global population expected to peak at 9 billion by 2050, and >80% of global fish stocks currently fully or overexploited (and aquaculture is at least in part dependent on capture fisheries), the contribution of fisheries looks set to decline. The challenge is therefore determining how better management, an ecosystem perspective, and more efficient utilization of fisheries waste can support fisheries products continuing to contribute significantly to “feeding the world” up to and beyond the population peak.

Westland petrels Procellaria westlandica breed only near Punakaiki on the West Coast of New Zealand. About 80 km offshore from their breeding colony, New Zealand's largest commercial fishery (for hoki Macruronus novaezelandiae) operates from mid June to early September, coinciding with the Westland petrel's breeding season. It has been assumed that Westland petrels feed extensively on fisheries waste and that this habit has been at least partly responsible for the increase in the Westland petrel population. Some seabird biologists have expressed concern that if a species comes to depend on scavenging at fishing vessels, such a species could experience a food crisis if fishing operations changed in a way that reduced the quantity of waste discharged. The aim of this research was to assess how dependent Westland petrels have become on fisheries waste for food. Diet studies showed that during the hoki fishing season, waste accounts for more than half by weight of the solid food Westland petrels bring back to the colony to feed their chicks. After the hoki season, waste contributes only about a quarter of their diet as birds switch to more natural prey and scavenge a wider variety of fish species presumably from smaller, inshore fishing vessels. Much of the fisheries waste eaten by Westland petrels was flesh which could not be identified using traditional techniques. The electrophoretic technique iso-electric focusing increased the number of fish samples that could be identified and consequently the diet was interpreted differently than it would have been had only traditional diet analysis been used. The survey of Westland petrel distribution off the west coast of the South Island, found that although hoki fishing vessels influence the distribution of Westland petrels, only a small proportion of the Westland petrel population appears to utilise this food resource at any one time. Westland petrels were tracked at sea by VHF radio telemetry and then by satellite tracking. Satellite tracking showed that there is considerable variation in the amount of time Westland petrels spend in the vicinity of fishing vessels. On average, satellite tracked birds spent one third of their time near vessels, but they foraged over much larger areas than that occupied by the West Coast South Island hoki fishing fleet. Although fisheries waste is an important component of the Westland petrel diet, it appears that the situation is one of opportunistic use of a readily available resource, rather than one of dependence. Several features of the Westland petrel's breeding biology and foraging ecology suggest that Westland petrels could compensate for a reduction in waste from the hoki fishery by switching to other sources of waste and increasing their consumption of natural prey. Nevertheless, much remains unanswered concerning the role of fisheries waste in the Westland petrel's diet. In particular, quantifying the waste available to seabirds, and the success of Westland petrels in acquiring that waste compared to other scavenging species, is needed in order to better predict the effect of a reduction in fisheries waste on Westland petrel population size.

Waste rice in harvested fields and natural seeds in moist-soil wetlands are important foods for waterfowl in the Mississippi Alluvial Valley (MAV). Waste rice declines significantly between harvest and late autumn. I conducted experiments in 19 rice fields in Arkansas and Mississippi during autumns 2003 and 2004 to evaluate the ability of common post-harvest practices to conserve waste rice between harvest and late autumn. Greatest mean abundance of waste rice in late autumn occurred in standing stubble (x&95 = 105 kg/ha; CL = 72.84, 150.16 kg/ha) followed by burned (x&95 = 72 kg/ha; 49.57, 105.81 kg/ha), mowed (x&95 = 67 kg/ha; 46.65, 97.42 kg/ha), rolled (x&95 = 51 kg/ha; 35.54, 73.076 kg/ha), and disked stubble (x&95 = 48 kg/ha; 33.26, 68.41 kg/ha). I recommend leaving stubble or burning fields to create interspersion of stubble and water after flooding. Additionally, I estimated abundance of moist-soil seed in 72 management units on public lands throughout the MAV for autumns 2002-2004. Mean seed abundance was 496 kg/ha (SE = 62). I recommend increased active management of moist-soil wetlands to mitigate decreased availability of waste rice in the MAV.

ENGLISH ABSTRACT: Cape hake (Merluccius capensis and M. paradoxus) is commercially the most important trawl-caught fish off the South African, coastline and due to current intensive fish processing procedures Cape hake contributes the most to the total fishwaste production. Besides its commercial importance fish is also regarded as one of the single most important consumable natural resources, either in the raw or frozen form. Most of South Africa's commercially trawled demersal fish has already been partially cleaned (i.e. headed and gutted) before landing with non-marketable bycatch and hake-waste normally disposed of as discards, resulting in a waste of a potential protein source. This study was thus aimed at fulfilling several objectives namely: observing the current large-scale commercial Cape hake harvesting procedure; constructing prediction models for several morphological parameters (whole hake mass, headed & gutted hake mass, hake head mass, hake head length, hake head breadth and hake head height) of Cape hake (Merluccius ssp.), using whole hake length as the independent variable; and determining the chemical composition (moisture, protein, fat, ash, macro and trace elements) of several hake head sections (clean head, neck flesh, tongue, tongue cartilage, jaw, gills, heart, intestines, gut, kidney, kidney & kidney bone and gut & gall); determining the effect that storage has on the fatty acid profile of both the clean head and neck flesh sections. The results obtained would supply necessary data required for techno-economic investigations in the use of hake heads. For each of the six prediction models constructed, there was an increase in the variance of the data points of categories 3 (64-80 cm) and 4 (>80 cm) as opposed to categories 1 (30-46 cm) and 2 (47-63 cm). This could be attributed to a smaller sample set for both categories 3 and 4 or due to an expected increase in the variance when investigating larger biological samples. There was also a clustering of data in the three areas for each prediction model namely, within category 1 and across categories 2 and 3 and 3 and 4. This emphasised the latitudinal stratification of the Cape hake population by age, hence their stratification by size. The prediction models constructed for both boat trips 2 and 3 differed significantly (p<0.01) from that of boat trip 1, with the exception of the hake head length (cm) prediction model. The constructed prediction models, for each of the three respective boat trips, showed good predictive abilities as was indicated by the low Mean Square Error (MSE) values for the test sets, and high Pearson's correlation coefficient (r) values. These prediction models can be used in the fishing industry with confidence for Cape hake within the time frame each respective boat trip was carried out. The neck flesh could be regarded as the most important concerning chemical composition whereas the jaw could be seen as the most important when one considers mineral content. This therefore means that the jaw section, once appropriately processed is a potential Ca, Na and Fe source for supplementing diets of people suffering from a Ca, Na or Fe deficient diet. With regard to chemical status the neck flesh section is seen as a good potential source of both protein and fat, which could be attributed to the fact that hake muscle constitutes a major portion of this section. This section could thus be used to supplement the protein and fat of an existing food product, which is protein and fat deficient for people suffering from a protein and fat deficient diet. Similarly, a market could be created for the production of an economical food product with the neck flesh section being the main ingredient. Once this have been accomplished, fishing vessels may be persuaded to retain their Cape hake fish-waste for further processing due to the value of the prepared food products and thereby maintain profitability while abiding to governmental law. In conclusion non-government scientists should have more input in the decision-making process concerning matters affecting South Africa's marine biodiversity in order for future key policy and legislation drafts to be effective. Improvement of current fish preservation techniques and the known chemical composition of currently discarded material will result in informed decisions of future matters concerning its disposal.
AFRIKAANSE OPSOMMING: Kaapse stokvis (Merluccius capensis en M. paradoxus) is kommersieel Suid-Afrika se belangrikste vis spesie. Aangesien die Suid-Afrikaanse visprosesseringsbedryf baie intensief is, dra die Kaapse stokvis verwerkingsindustrie die grootste gedeelte by tot die totale visafval produksie. Die meeste van Suid-Afrika se visvangste word gedeeltelik skoongemaak voor landing terwyl nie-kommersiële byvangste en visafval gewoonlik oorboord gegooi word tydens die vangproses. Dit lei tot die vermorsing van 'n potensïele proteïen bron. Hierdie studie was dus gemik om: die huidige grootskaalse kommersiële Kaapse stokvis visvangsproses waar te neem; voorspellingsmodelle vir verskeie morfologiese parameters (heel vis massa, vis massa sonder kop en binnedele, stokvis kop massa, stokvis kop lengte, stokvis kop breedte en stokvis kop hoogte) vir Kaapse stokvis (Merluccius ssp.) te ontwikkel deur die hele lengte van die vis te gebruik as die onafhanklike veranderlike; die chemiese samestelling (vog, proteïen, vet, as, makro en spoor elemente) van verskillende dele van die viskop (skoonkop, nekweefsel, tong, tong kraakbeen, kaak, kiewe, hart, ingewand, derm, nier, nier & nierbeen en derm & gal); sowel as die effek van opberging op die vetsuurprofiel van beide die skoonkop en nekweefsel dele van die Kaapse stokvis kop. Hierdie resultate sal dan gebruik word vir die tegnies-ekonomies ondersoek in die gebruik van Kaapse stokvis koppe. Vir elk van die ses voorspellingsmodelle ontwikkel, was daar 'n vermeerdering in die variansie van die datapunte vir kategorieë 3 (64-80 cm) en 4 (>80 cm) teenoor kategorieë 1 (30-46 cm) en 2 (47-63 cm). Dit kan moontlik wees as gevolg van die kleiner monster trekking vir beide kategorieë 3 en 4 of as gevolg van verwagte toename in variansie wanneer groter biologiese monsters ondersoek word. Daar was ook 'n groepering van data in drie plekke vir elke voorspellingsmodel naamlik; binne in kategorieë 1 en oor kategorieë 2 en 3 en 3 en 4. Dit beklemtoon die geografiese breedte van die Kaapse stokvis populasie op grond van ouderdom, en dus die geografiese breedte op grond van grootte. Die voorspellingsmodelle ontwikkel vir beide die tweede en derde bootvangs het betekenisvol verskil (p<0.01) van die eerste bootvangs, behalwe die vir die stokvis kop lengte (cm) voorspellingsmodel. Die voorspellingsmodelle vir elk van die bootvangste het goeie voorspellingsvermoë getoon wat bewys is deur die lae Gemiddelde Kwadraat Fout waardes vir toetsgroepe en hoë Pearson's korrelasie koeffisiënt (r) waardes. Hierdie voorspellingsmodelle wat ontwikkel is, kan dus met vertroue in die Kaapse stokvis visvangsbedryf gebruik word mits dit ooreenstem met die periode waarin elke bootvangs uitgevoer was. Die nekweefsel gedeelte is die mees belangrikste met betrekking tot chemiese samestelling en die kaak die belangrikste in terme van minerale samestelling van die verskeie viskop dele. Die kaak is dus, as dit voldoende geprosesseer word, 'n goeie potensïele bron van Ca, Na en Fe en kan dus gebruik word om die dieet van mense wat 'n gebrek het aan hierdie minerale aan te vul. Met betrekking tot die chemiese samestelling van die nekweefsel gedeelte kan dit beskou word as 'n goeie potensiële bron van beide proteïen en vet, wat toegeskryf kan word aan die feit dat spierweefsel 'n groot deel uitmaak van hierdie viskop gedeelte. Hierdie viskop gedeelte sal dus uitstekend wees om die proteïen- en vetinhoud van 'n voedselproduk wat van nature 'n lae proteïen- en vetinhoud het te verhoog en hierdie produk sou dan geteiken word op daardie gedeelte van die gemeenskap wat 'n proteïen en vet tekort in hul dieet het. As dit eers alles in plek is, dan sal die visvangs bedryf hul Kaapse stokvis afval behou vir verdere prosessering deurdat dit gebruik word om die voedingsinhoud van bestaande voedsel soorte sal verbeter en terselfdertyd sal hulle aan wetgewing voldoen. Gevolglik sal nie-regerings navorsers meer betrokke moet wees by die besluitnemingsproses met betrekking tot sake wat die Suid-Afrikaanse mariene lewe affekteer en wat toekomstige wetgewing meer effektief sal maak. Die verbetering van huidige vis preserveringstegnieke gepaardgaande met die kennis van die chemiese samestelling van die Kaapse stokvis koppe sal lei na beter toekomstige besluite oor die afset daarvan.

This research looks at the change in ethical sensibilities towards a mangrove in a fishing colony in the periphery of Rio de Janeiro, Brazil, and at how they may have changed as the mangrove became a protected area and entered the environmental assemblage. Formerly called Z-1, this was the first of 800 cooperative fishing colonies founded along the Brazilian coast in 1920 as part of a government initiative. The study unveiled the following pattern around the mangrove: from being a source of livelihood and place for communal activities up until the 1970s, it became the locus of an environmental movement in the 80s and 90s after it was devastated by a big fire. The concrete outcome of the movement was the creation of the APARU, Area of Environmental Protection and Urban Regeneration, which meant that after more than seventy years under a system of tutelage by the Navy, the colony and the mangrove were subjected to an environmental form of governance administered by the City Council, and the mangrove went from being a taken-for-granted thing to an environmentally-oriented concept. It finally fell silent and isolated as it became increasingly polluted, even if ‘protected’ by a municipal decree. The main argument presented is that, as the mangrove passed from nature to environment, which implied a change in governance from the Navy to the Department of Environment, people found creative ways of holding on to its thingness, and to ethical values that at times conflict with the broader environmental assemblage. Those local ethics forge the links that sustain an ecological assemblage, and the ethics prescribed by the environmental governance currently in place can be undermined by more embedded values. That said, local knowledge and practices are environmentally informed, and different ways of being political emerge. This community was not only created literally on a mangrove, but it was also symbolically and politically reproduced through the mangrove, and even more so after it became a protected area. The dialectical outcomes of the relationships between human beings and the mangrove, and between human beings as they multiply, transform the landscape continuously, just as the mangrove in its perpetual unfolding impresses itself upon human matters and sustains the social ordering of things. As new elements are assembled around the mangrove, from discarded utensils to stories of environmental activism, the mangrove is enacted as heritage, as nature, as a biome, as culture, as pollution, as an institution, and as environment. This thesis hopes to contribute towards the broader body of literature on environmental anthropology, political ecology, and anthropology of moralities, by focusing on ‘human-disturbed environments’ (Tsing 2013) and bringing attention to the value of local perceptions in policy making.

Os resíduos sólidos orgânicos gerados pelas indústrias de pescado no Brasil, tradicionalmente são descartados ou encaminhados às fábricas de farinha de peixe. Alguns dados acerca desta atividade foram investigados neste trabalho por meio de um estudo exploratório de caráter quantitativo e qualitativo, descritivo quanto aos fins e bibliográfico e de campo quanto aos meios. A ferramenta utilizada foi um questionário estruturado que após submissão a um grupo focal formado por especialistas no tema, foi aplicado às empresas de pesca habilitadas pelo Serviço de Inspeção Federal SIF, afiliadas ao Sindicato das Indústrias de Pesca do Estado de São Paulo SIPESP. Finalizada a fase de adequação do instrumento de coleta de dados, efetuou-se contato via Empresa Brasileira de Correios e Telégrafos, com as indústrias de pesca habilitadas pelo SIF, em atividade nos cinco estados de captura mais expressiva da federação, com a finalidade de convidá-las a participar do estudo, através de um sítio na rede mundial de computadores. Após noventa dias, foram finalizadas as coletas via Internet. Novamente, as empresas foram contatadas via telefone e correio eletrônico, para o agendamento de visitas in loco. Uma empresa processadora de resíduos no Estado de Santa Catarina foi objeto de um estudo de caso que investigou o custo de transferência do resíduo entre indústrias geradoras e processadoras. Dentre as 114 empresas habilitadas pelo Serviço de Inspeção Federal - SIF foram contatadas 57, das quais 29 colaboraram com o estudo, sendo que 15 declaram-se na categoria de pequena empresa. Para análise dos dados utilizou-se estatística descritiva, na qual os mesmos foram apresentados em forma de figuras e tabelas. O beneficiamento, principalmente para obtenção de filés, é a atividade de maior geração de resíduos. A retirada de resíduo das instalações gera custos em 83% das indústrias avaliadas. Despesas com movimentação de resíduos influenciam pouco o equilíbrio econômico em 44% das empresas. O armazenamento em câmara refrigerada (64%) e o transporte para descarte (32%) são considerados os principais componentes do custo de gestão de resíduos. Das indústrias que colaboraram com a pesquisa, 44% destinam seus resíduos para aterros e lixões públicos. O transporte do resíduo da empresa geradora até o local de descarte ou processamento apresenta um custo de R$ 0,52 a t / km, excluídos impostos e seguro. Existe uma quantidade considerável de resíduo sendo gerada pelas indústrias de pesca e apenas uma pequena fração vem sendo aproveitada, fato que demonstra que o descarte ainda é a prática mais comum, e que evidencia a pouca inserção do setor de pesca brasileiro na busca pela sustentabilidade.
The organic solid waste generated by fish industries in Brazil, traditionally are discarded or forwarded for fish meal factories. Some data on this activity were investigated in this work through an exploratory study of quantitative and qualitative characteristics, descriptive as to the purposes and bibliographical and field as to the means. The tool used was a structured questionnaire after submission to a focus group composed of experts on the subject, it was applied in fishing enterprises authorized by the Federal Inspection Service - SIF, affiliated to the Fishing Industries Union of São Paulo State - SIPESP. Completed the phase of adequacy of the data collection tool, a contact via the Brazilian Post and Telegraph with the fishing industries authorized by the SIF active in five states capture more expressive of the federation was made to invite them to participate by providing information through a website on the World Wide Web. After ninety days, the collections via the Internet were completed. Companies were again contacted via telephone and email for the scheduling of in loco visits. A waste processing company in the state of Santa Catarina was the subject of a case study that investigated the cost of transferring the waste from generators to processing industries. Data analysis were performed with the use of descriptive statistics and these were presented in pictures and tables. Among the 114 companies qualified for the Federal Inspection Service - SIF, 57 were contacted, 29 of which collaborated with the study, being 15 declared themselves as small business. The processing, mainly for obtaining filet, is the largest activity of waste generation. The removal of the waste, generated cost on 83% of the industries studied. Costs on waste movement have a little influence on the economic balance to 44% of the companies. The refrigerated storage (64%) and transport to disposal (32%) are considered the main components of the cost of waste management. Of the industries that contributed to this survey, 44% send their waste to landfill and public dumps. The transfer of waste from the company generating to the disposal site has a cost of R$ 0.52 t / km, excluding taxes and insurance. There is a considerable amount of waste being generated by the fishing industries, and only a small fraction is being utilized, which demonstrates that the disposal is still the most common practice, and this is an evidence about the few insertion of the fisheries Brazilian sector to reach the sustainability.

Streszczenie:
Both liquid and solid wastes from Pacific whiting surimi manufacturing were characterized and value-added products were recovered. A proteinase in surimi wash water (SWW) was determined to be cathepsin L with Mr 54,200 on SDS-substrate gel. Heat treatment and acidification shifted the activity zone to M [subscript r] 39,500. No evidence of calpain, cathepsin B or H activity was found. Cathepsin L from SWW was recovered by ohmic heating (55°C for 3 min), ultrafiltration, and freeze-drying with overall yield of 0.83 g protein/L SWW and 78% recovery of activity. A 5.9 purification fold was achieved by these processes. The recovered enzyme had an optimum activity at pH 4.0 and showed preferable hydrolytic activity towards casein, acid-denatured hemoglobin and myofibrils. β-Mercaptoethanol, dithiothreitol and urea enhanced the enzyme activity. The recovered proteinase showed 18.5% residual activity after 7 wk storage at 4°C. Proteolytic activity in solid waste and digestive organs from Pacific whiting was investigated. Pepsin-like proteinase predominated in solid waste, while trypsin-like proteinase was predominant in viscera. Carboxypeptidase b was found in both viscera and solid waste. Protein hydrolysate was produced from Pacific whiting solid waste (PWSW) using commercial proteinase, Alcalase, under optimum hydrolysis conditions. Enzyme concentration, reaction time and waste/buffer ratio affected the hydrolysis and nitrogen recovery (NR). Correlation between the degree of hydrolysis (DH) and NR was high (R₂=0.978). Freeze-dried hydrolysate contained 79.97% protein and showed similar amino acid composition to PWSW and Pacific whiting muscle but tryptophan was reduced. With different DH (20, 30, 40, 50, 60%), surface hydrophobicity, total and surface sulfhydryl content decreased as the DH increased. The hydrolysate showed a high solubility over a wide pH range. Fat adsorption and fat binding capacity were reduced, while foam expansion was enhanced with an increased DH. Hydrolysate with DH of 30% showed highest emulsifying activity. Low emulsion stability and high foam stability were obtained in all hydrolysates tested. Hydrolysate showed antioxidant activity, but no obvious differences in activity were found with varying DH and hydrolysate concentrations.

Streszczenie:
Exploitation of aquatic natural resources contributes to important economic and social services to the world’s population. According to the latest FAO statistics, aquaculture production reached 167.2 million tons in 2014, representing values of nearly USD285 billion. Particularly, crustacean production represents 9% of the total, representing almost 7 Mt, which generates a great amount of waste, mainly from the exoskeletons. The increasing tendency toward a responsible and sustainable production that combines economic development and the conservation of natural resources has generated changes regarding production management. Within this framework, the biotechnological use of waste not only provides an added value to materials that have been traditionally discarded but also can reduce the environmental contamination resulting from their chemical processing. Thus, there is an opportunity for the preparation of substances with high aggregate value, such as chitin and its derivatives (chitosan, chito-oligosaccharides, and glucosamine), proteins, lipids, and carotenoid pigments. Byproducts resulting from the processing of crustaceans have potential applications in the food, pharmaceutical, textile, biomedical, and agricultural industries as well as in bio- and nanotechnology. In addition, the biomimetic of the structures, functions, and properties of the exoskeletons of crustaceans and the processes involved in their formation constitute the basis for the development of diverse structures, such as laminates or buildings, the creation of new materials that are potentially useful in diverse areas, and the adoption of novel modes of technologies.

<em>Abstract.—</em>As the United States has become increasingly urbanized, angling participation has declined. Urban fishing programs provide an opportunity to reverse this trend by effectively targeting new anglers while increasing fishing opportunities for current or recently lapsed urban anglers. There are three essential components in a successful urban fishing program: a resource with clean water and a quality fishery close to current or potential anglers, facilities to accommodate anglers, and advertisement of the fishery to inform and recruit anglers. Early in the development of an urban fishing program, urban anglers’ interests should be assessed and the program should be developed to meet these interests. Next, access to a quality fishery must be developed—either by creating new bodies of water or enhancing existing ones. Depending upon the level of fishing pressure and the species of interest to anglers, supplemental stocking and intensive management may be needed to maintain the fishery. Amenities such as restrooms, picnic areas, docks, and waste receptacles may also be important. Different angling groups may desire different amenities, so providing different sites to cater to these different groups is advisable. Once the facilities and amenities are in place, the resource must be marketed to targeted potential anglers. The marketing strategy should be tailored to each market segment being targeted. Lapsed anglers are the most easily recruited segment and should be a top priority for advertising. Minorities and children are also commonly targeted. As the U.S. population becomes more urbanized, urban fishing opportunities will continue to grow in importance. Without these opportunities, urbanites will likely be drawn toward the numerous other recreational activities that are conveniently available in urban centers, leading to further declines in angling involvement and concern for natural resource conservation and the environment.

This chapter gives a good grounding in view of the development of innovative technological solutions that enhance the valorisation and efficient use of marine resources through the integration of value chains, in a logic of circular economy, articulating food industry, biotechnology, and fisheries. Economy is a business model that extends the circular economy principles of sustainability and reuse to activities influencing the world's aquatic ecosystems, not only seas, oceans, and coastlines, but rivers and lakes, too. Both combine concepts of design out waste and pollution, keep products and materials in use, regenerate natural systems, sustainability, and share economy. However, the blue economy goes further to strengthen competitiveness by lowering costs and pursuing a more effective economy of scale. Consequently, the circular economy is becoming increasingly tinged with blue. The aim of this chapter was to present two case studies on sustainable business strategies for the circular blue economy.

Streszczenie:
This paper contributes to the comprehensive approach for sustainable and balanced development of bioeconomy as a cross-cutting economic sector and focuses on the drivers of Lithuanian bioeconomy strategy. Lithuanian bioeconomy strategy development can be motivated by country’s specialization and, compared with other EU member states, strong performance in terms of recent growth in all biomass production and fully bio-based manufacturing sectors. However, Lithuanian bioeconomy strategy depends not only on the current state and trends of its subsectors, but also on the drivers that will be forcing and shaping them in the future. The authors decomposed these drivers into global, European and national. Using content analysis of the EU, OECD and European countries’ legal acts, global drivers such as depletion of natural resources, growing population, increasing environmental pressures and climate change were identified. Applying content analysis of the EU and European countries’ bioeconomy strategies and analysis of case studies of good practices in European countries and regions, the following drivers at European level were identified: common EU bioeconomy policy, strategy and action plan; assurance of biomass availability and sustainability, as well as efficient biomass value chain; the need to strengthen markets and competitiveness of the bioeconomy subsectors; the necessity of close cooperation among all stakeholders, namely politicians, business people, scientists and the public; the need of the development of new technologies and processes, especially industrial biotechnology. The research revealed that the bioeconomy development in Lithuania has been regulated and promoted through certain sectoral policies: agriculture, forestry, fisheries, energy, environment (including waste management), scientific research, innovation and biotechnology development. In the future, the cross-sectoral links and interactions in the Lithuanian bioeconomy will increase due to the scarce biomass, applying the cascading principle in the biomass refinement, transition towards circular economy, and the development and implementation of innovations.

Until now, Korean aquaculture industry has been grown largely in quality and quantity. However, an increase of quantity has caused lots of problems like sea pollution lately. Nearly 82% of Korean aquaculture farms had been installed mainly at inshore of the southern sea, so, sewage, factory wastes, high density of farms at the limited area and autoinfection have deteriorated inshore fisheries. Now, the open sea has been on the rise for the solution to these problems since it has clear seawater that will expect to decrease the environmental pollution with much current. As a matter of fact, it is impossible to move the existing fish cages to the open sea due to the rough environmental conditions such as higher waves, strong currents etc.; therefore, it is necessary to develop new fish cage equipment that will fully meet the open sea conditions. In this research, the theoretical study and experimental analysis have been carried out for the structural fish cage design which is feasible for the open sea.

Like other Small Island Developing States (SIDS), Caribbean island economies have intrinsic characteristics that make them vulnerable to external shocks. The recent pandemic highlights the structural problems of small island economies. Due to their remote location and small size, islands lack economies of scale and rely on global supply chains, which are currently disrupted. Islands depend either on service-based economic activities like tourism, which are being affected during the current crisis, or on a single commodity, which makes them extremely vulnerable. Islands must rethink their approach to development, adopting one of sustainable development. The Sustainable Islands Platform aims to create a new approach that targets the needs of Caribbean islands and prescribes circular economy-inspired interventions in key areas such as sanitation, waste management, agriculture, fisheries, tourism, energy, transportation, and health. Traditional approaches have not proven successful in solving developing problems on SIDS. Therefore, a new concept that considers islands in a new way should be considered.
