Social Economic Determinants of Adoption of Fish Farming in Gem Sub-County, Siaya County, Kenya

The demand for fish in Kenya has been steadily increasing, prompting the exploration of alternative methods such as fish farming to address this rising demand. However, the adoption of fish farming in Gem Sub-county, Siaya County, Kenya, has faced several challenges, resulting in a low success rate of only 13.9% in fish farming projects, leading to insufficient fish supply. This study aimed to analyze the factors influencing the adoption of fish farming in Gem Sub-county. The research was guided by four objectives; determining whether training influence farmers’ adoption of fish farming, determining the availability of fish farming resources on the adoption of fish farming, investigating the availability of fish markets on the adoption of fish farming and assessing fish farmers' attitude on the adoption of fish farming in Gem Sub-county, Siaya County, Kenya. The study employed the theory of innovation diffusion and a descriptive survey research design to investigate the adoption of fish farming in a specific area. The target population included 140 fish farmers, 9 area Chiefs, and 9 Officials from the Fishery Department, totaling 158 individuals. To form a representative sample, 3 out of 9 locations (30%) were selected, resulting in 42 respondents (30% of 140 fish farmers). Purposive sampling was used to select these locations, with the Area Chiefs and Fishery Department Officials coming from these sampled areas due to their expertise on fish farming projects. Data collection methods varied: questionnaires were used for fish farmers, while interviews were conducted with officials from the Fishery Department and Area Chiefs. To validate research instruments, a pilot study involving 4 fish farmers from a specific location was conducted to ensure reliability and validity. The data analysis process began with identifying common themes, assigning codes and labels to relevant data, and then calculating frequencies to provide descriptive information about the respondents. Quantitative data was analyzed using descriptive statistics like frequencies and percentages, as well as inferential analysis employing Pearson's Product Moment Correlation Analysis, with the aid of Statistical Packages for Social Science (SPSS 23). The findings were presented using tables and charts. Qualitative data was analyzed qualitatively, aligned with the specific research objectives, and presented in narrative forms. The study established that there was a positive association between the frequency of farmers' training and the number of farmers who adopted fish farming (r = 0.991 and a significant level (p-value) of 0.000. In addition, correlation between the frequency with which the government markets fish and fish products and the number of farmers who have undertaken fish farming was positive (r = 0.976 and a significant level (p-value) of 0.000). Lastly, the association between fish farmers' interest in fish farming and the number of farmers who adopted fish farming was positive (r = 0.948 and a significant level (p-value) of 0.014. The study concluded that fish farmers in the studied area lacked meaningful training, negatively impacting their ability to adopt fish farming due to a lack of necessary skills and knowledge. Additionally, the unavailability of essential resources hindered effective fish farming implementation, while the limited access to fish markets, marked by intense competition, both locally and internationally, further discouraged fish farming adoption. In response to these findings, the study recommended that the Fishery Furthermore, it advised that the government, particularly through the Ministry of Agriculture and Fisheries, allocate more funds to support fish farming and explore new markets for local fish farmers, as incentives for the wider adoption of fish farming practices.

Review on Status of African Catfish Aquaculture in Nigeria

World aquaculture production continues to grow to meet increasing demand for fish, especially as the fish catch has stabilized and is boosting aquaculture production as the only hope of meeting demand for fish. The aquaculture industry involves the farming of many species of fish of fresh or brackish origin and important freshwater fish species include the North African catfish, also called the African catfish (Clarias gariepinus). Its production is increasing as total aquaculture production is also increasing and its culture is spreading globally, with Nigeria officially declared as producing the largest annual aquaculture quantity of African catfish (clarias garipenous) globally at 3% of the total world production rate per year. There is a significant culture of African catfish in Ghana, currently approaching several decades with 1% of total world production. Ghana has been one of the largest producers of tilapia, pike, and catfish. This review focused on African catfish aquaculture in Ghana and Nigeria, comparing production and industry prospects in the two countries. This review indicates that Nigeria had a higher production rate of African catfish from the 1980s to 2018 than Ghana at the ratio of 3:1. Nigeria's catfish aquaculture industry has shown more significant advancements and expansion over the past two decades, Ghana has also experienced steady growth. Nigeria has established itself as a major player in the African catfish market, both in terms of production volume and international trade. Ghana's industry, although smaller, focuses on meeting local demand and has the potential for further development and expansion.

Eustrongylides spp. (Nematoda: Eustrongylidae) em Polypterus endlicheri na região central do Rio Grande do Sul, Brasil

Abstract The demand for ornamental fish has increased in recent years in Brazil, however, the aquatic environment of artificial breeders facilitates the invasion of pathogens, including parasitic zoonoses, which are a limiting factor for production causing economic losses in creations. Knowledge of the distribution of agents causing parasitic diseases is important so that we can intervene in breeders, therefore, the objective of the present work is to report the occurrence of infection by Eustrongylides spp. (Nematoda: Eustrongylidae) in Polypterus endlicherii (Polypteriformes: Polypteridae) in central Rio Grande do Sul, Brazil. The nematode was identified after being released a cyst in the scales, of a fish of the species P. endlicherii. It can be concluded that this is the first record of the occurrence of Eustrongylides spp. larvae in fish in Rio Grande do Sul, showing that the parasite is present in the central region of the state. Therefore, further studies should be carried out in order to verify the presence of the parasites in fish intended for human consumption. It should also be noted the need to be more careful when feeding fish with oligochaetes, especially those intended for human consumption.

Импортные потоки стран Азиатско-Тихоокеанского региона: место товаров дальневосточного экспорта

Based on the analysis of import flows of the Asia-Pacific (NEA-3 and ASEAN) in the period 2015–2021, it is shown that a stable commodity-geographical structure of supplies has developed in the region. About half of the volume of imports in USD falls on computers, communications equipment, parts and components used in their production; mineral fuels, mineral oils and products of their distillation; bituminous substances; mineral waxes; iron ores and concentrates. At the same time, there is a high level of interdependence of mutual trade flows within the region. Such an import structure is based on the complementarity of the supply and demand of the Asia-Pacific countries. It is shown that only the USA, Australia and Saudi Arabia are large-scale external exporters for ASEAN+3. Of the traditional exports of the Far Eastern Federal District (FEFD), only fuel and energy products had a stable niche with a steady but small-scale demand for fish, forestry and metallurgical products. Thus, for the NEA-3 countries, the Russian Federation was an important supplier of energy resources, and Japan and the Republic of Korea got about half of fuel and energy products from the Russian Far East. Russia was also the largest supplier of fish and seafood for China and the Republic of Korea. Moreover, almost all Russian exports of fish products to the ASEAN+3 countries were supplied from the FEFD. Despite the fact that since 2007 the Russian Federation has gradually increased export customs duties on round wood, which had strong demand in the region, during the study period, Russia remained a key supplier for China, and for Japan it was in the top ten. Approximately 25% of Russian exports of wood and articles of wood to the Asia-Pacific were supplied from the Russian Far East

Exploring the potential of fish waste (Sardinella fimbriata) through pyrolysis: A study of kinetics and thermodynamics using isoconversional methods

The growing global demand for fish has led to an increase in fish waste (FW) production, necessitating efficient waste management strategies. Pyrolysis is a promising way to convert fish waste into high-value products. To achieve optimal waste mass reduction and gain insights into the pyrolysis process, estimating kinetic parameters is essential. This study investigated the pyrolysis of FW, Sardinella fimbriata, a previously unexplored waste source, using a thermogravimetric analyser. The study determined an average activation energy value of 84–124 kJ/mol using model-free isoconversional methods including Flynn-Wall–Ozawa, Kissinger–Akahira–Sunose, and Starink, whereas pre-exponential factor values were predicted to be between 102 and 1011 s−1. Further analysis using Criado's reduced master-plot approach showed that the experimental curves for pyrolysis coincided with many different theoretical plots for reaction mechanisms, with a concentration on reaction-order models. The analysis of thermodynamic parameters showed positive values of enthalpy change and Gibbs energy change for S. fimbriata FW pyrolysis, suggesting that the process is endothermic and non-spontaneous, while negative values of entropy change were observed across all conversion degrees as a result of the breakdown of complex organic molecules into simpler compounds. This study provides insights into the feasibility of thermal processes and offers new guidance for FW waste management and resource recovery, expanding the understanding of pyrolysis kinetics and thermodynamics for fish waste treatment.

Protein Alternatives for Use in Fish Feed – Life Cycle Assessment of Black Soldier Fly, Yellow Mealworm and Soybean Protein

Abstract More production is needed as fish consumption increases. The increasing demand for fish also has implications for fish feed, the efficiency of its production and sustainability. Three protein alternatives – Black Soldier Fly, Yellow Mealworm, and Soybean – are compared to assess the sustainability of raw materials and their environmental impact. Each alternative has advantages and disadvantages. The advantages of Black Soldier fly and Yellow Mealworm are a valuable source of protein, sustainable growth (as the feed can be used in food waste) and no need for arable land. The disadvantages of Black Soldier fly and Yellow Mealworm are cost, unbalanced diets can adversely affect growth, and the nutritional impact on fish varies depending on the species of fly or mealworm. The advantages of soybeans are price, availability, and high protein content, while the disadvantages are the lack of essential amino acids, which affect the quality of the fish, and poor taste. An LCA study has been carried out on the proteins of black soldier fly, yellow mealworm and soybean. The most important impact categories from the PEFCR are climate change, particulate matter, acidification, land use, terrestrial eutrophication, and water use. The total single point value for the Black Soldier fly protein is 1.43E+01 µPt, the Yellow mealworm protein is 3.89E+02 µPt and the Soybean protein is 9.72E+01 µPt. The significant effect is due to the electricity consumption and the ingredients used in the feed. Sensitivity analysis was carried out for Black Soldier fly protein and Yellow Mealworm protein production where feed formulation was varied. In both sensitivity analyses, the lower environmental impact is from the new feed structure, which may be due to the use of food waste and wheat as feed ingredients in the new feed structure.

Establishment of Local Fish Farm “La’ Prestige Agro” LLC in Nigeria

This project aims to create a unique and most efficient large-scale farming of freshwater fish for daily consumption in Nigeria. According to the CGIAR African Fish Research Program 2019. Nigeria has one of the highest levels of fish consumption in Africa. In Nigeria, Africa's most populous country, fish is an important part of the household diet. Fish makes up about 40% of the protein consumed in the country, with fish consumption at 13.3 kg per person per year [17]. According 2021 Fish Information and Services report, Nigeria spends 250 billion naira approximately (US$560 million) annually on fish importation [6, 7]. The mainly import fish from Japan, Norway, Russia, United States and Netherlands. Nigerian’s population fish demand is approximately 3.3 million metric tons but the country is only able to produce 1.1 million metric tons locally. With a report on this study and as a Nigerian citizen who has lived in Nigeria and has a family living there, with current updates on the Nigerian fish market and its economic status. It is estimated that Nigeria lacks 60 percent of the fish production capacity equivalent to the country's fish consumption needs. Thus, investing in fish production in Nigeria is profitable and comes with the least investment risk of bankruptcy as consumers are always available to buy once you have a successful production [8, 9]. Thus, our company has enough market space and high demand for fish to succeed in the Nigerian fish market. This will allow our company to earn enough profit to repay the investment loan and interest on it within the agreed time frame agreed with our investors.

Freshwater fish parasite diversity in West Bengal – A review

Aquaculture has the potential to meet the need of growing demand of fish in an affordable price. But in capture and in culture fisheries the fishes face diseases that interfere in the production of fish. The occurrence of disease causes the reduced production in aquaculture or reduce the marketable value of fish because of change of flesh quality, thus hampering the production. Freshwater fishes whether they are cultured or wild face different types of diseases in their skin, gills, fins, blood, and internal organs. The parasites that cause the diseases may be protozoans or metazoans.The main protozoan freshwater fish diseases are ichthyophthiriasis, trichodiniasis, costiosis, chilodonellosis. The most common metazoan parasitic diseases of freshwater fishes are dactylogyrusis, gyrodactylosis, argulosis, myxosporidiasis, ligulosis, ergasilosis, lernaesis, etc. The focus of this review is to screen the research studies that takes place on freshwater fish parasites of West Bengal. The review also aims to study the diversity of freshwater fish parasites in West Bengal, so that it will helps the researcher to get an idea about the freshwater fish parasites and their mode of infection in the fishes. The research work that takes place in different regions of West Bengal. Some of them reveal new species of parasites in fishes. Protozoan, cnidarian, acanthocephalan, nematode, cestode, trematode, crustacean parasites are identified in freshwater fishes of West Bengal. Among the protozoans cailiates, flagellates are identified. Trichodinids are very common protozoan fish parasites in most districts. Parasites under genus Myxobolus, Dactylogyrus, Gyrodactylus, Argulus, Lernea are common among the metazoans.

Blockchain Applications in Fisheries

Urbanization has led to increasing fish consumption, resulting in high demand for fish and fish products. Challenges in this sector, include fraudulent fish supply, overfishing, unscientific handling, quality concerns, etc. Blockchain-based systems in the seafood sector could provide traceability access to the seafood for the consumers and authorities to know if the seafood consumed/sold is legal, ethical, hygienic, economic, etc. Blockchain platforms like Ethereum promote secure digital collaboration of the actors across the supply chain eliminating the intermediaries. The literature documents a very limited number of blockchains that operate in the fisheries sector. Pacifical Atato is designed to promote and develop yellowfin tuna supply chains of Pacific island nations. Project Provenance Limited seeks to bring an end to the unsustainable fishing practices. Tuna distribution through transparent, novel chains is the goal of TraSeable solutions. Treum explored the investments to develop the supply chains of fisheries in the South Pacific. IBM’s Food Trust traces food supplies, including farmed shrimp from India, and is affiliated with retailers like Walmart, Nestle, etc. OpenSC is a World Wildlife Fund (WWF) project that ensures ethical product sourcing and uses QR (Quick Response) code scanning and RFID (Radio Frequency Technology) to track fish.

FISH INDUSTRY: A DISCOURSE ANALYSIS OF THE FUTURE PERSPECTIVE OF PAKISTAN

The research article outlines Pakistan's fisheries industry output from 1950 to the recent past and fishery product trading from 1980 to 2011. Based on economic research, the findings show that fish output and export continuously rose year after year. Despite this, the pace of development in fish output over the previous two decades has been quite modest compared to other emerging nations. The research also shows that inland aquaculture output in Pakistan is quickly outpacing marine aquaculture. On the contrary, no marine aquaculture methods exist or are supported to improve fish output. The article discusses and measures fisheries sector security and future development potential for coastal and non-coastal regions. In Pakistan, aquaculture has emerged as the most promising option to address fish demand, food security, livelihood, employment, and national GDP. Furthermore, it is critical to focus on marine aquaculture to restore marine fishing resources, which may generate livelihoods in coastal communities. Finally, the main idea of this article is to provide developmental techniques for authorities to grow and expand the aquaculture industry, which might provide numerous options for livelihood support in Pakistan. The research uses methodological triangulation to evaluate the on-ground reality from a broader perspective. Moreover, an online survey will be presented to evaluate the output of the fish industry of Pakistan.

The status and challenges of aquaculture development in Dodoma, a semi-arid region in Tanzania

Demand for fish is growing rapidly in Tanzania due to population growth and rising incomes. However, as fewer wild fish are being caught, there is a gap in fish supply. Aquaculture is a viable alternative source to meet the gap in fish demand. Tanzania has the perfect climate and land for fish farming. Aquaculture in fresh and salt water has grown quickly, yet the potential is not being fully tapped. Thus, the study assessed the growth of aquaculture in Dodoma, a rapidly developing semi-arid region of Tanzania, in order to determine its potential, challenges, and solutions. Thirty-six fish farmers from Dodoma urban district were visited and interviewed. The interviews gathered information about management practices, fish yield, and challenges. The findings show that aquaculture in the region began around 9 years ago, when the region began to expand. The aquaculture includes small-scale pond farming of Nile tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus). Fish yield was about 1925 kg ha−1 per culture cycle, and fish customers are definitely available. The main challenges were limited supply and high prices of fish feed and seeds, and limited water supply. Use of commercial feed, pond fertilisation, access to extension services, and ownership of a borehole were related to high fish yields in both species. Expansion of aquaculture in the region is possible with the improvement of extension services and training of farmers in proper breeding, feeding, and water management. To decrease water demands, integrated aquaculture, water recycling, and aquaponics should be encouraged.

Red de valor de los comerciantes del mercado del mar de Zapopan, Jalisco, México

Given the growing importance of the fishing and aquaculture sector (in 2021 the activity generated approximately 300,000 directjobs and 2 million indirect jobs) and the high demand for fish and shellfish, the value network was identified (The value networkallows analyzing to the economic and non-economic actors that participate) of the merchants of the sea market of Zapopan, Jalisco,whose purpose was to identify the leading company, as well as carry out an analysis of the parts of the network, recognize themembers and roles of each one of her. The methodological process consisted of in-depth interviews with important actors withinthe network, as well as the application of the mystery shopper technique within the sea market and self-service stores, in order toobtain information, data, which were later, captured, processed and analyzed. The results indicate the existence of an interesting andcomplex regional and national articulation, due to the number of intermediaries (at least four and up to seven) that touch the productand that have a utility. Eight types of well-defined local clients and from 14 states of the country were determined and classified.The national supply such as sea fishermen, riverside fishermen, estuary fishermen, fish farmers, etc... provide gutted, scaleless andfrozen fish or shellfish. For its part, the international supply supplies seafood or fish fillets, nuguets, in boxes or marquetas by kilos,with a quality certificate, traceability, prepared with some fine herbs or styles and vacuum packed, whose origin is: Vietnam, China,Indonesia. Finally, the degree of duplicity that international suppliers have (for the seafood market and self-service stores) must beconsidered, since in a decade the roles can be reversed and they are left out of the market.

IUU Fishing, Permasalahan Dan Upaya Pencegahannya Di Perairan Indonesia

IUU Fishing is a global issue in the world of fisheries, especially in Indonesian waters. The factors that cause IUU Fishing in Indonesian often occur are inseparable from the statement that Indonesian has potential and a strategic environtment in the global world, especially the condition of fisheries in other countries that have sea borders and fishery management systems in Indonesian. Factors causing IUU Fishing include the need for increased world fish demand, disparities in world fish prices, and overfishing. Losses experienced as a result of IUU Fishing in Indonesian can have social, economic, political and environmental impacts. In order to realize security in the marine and fisheries sector, orderly and uphold the law and human rights, it’s necessary to have efforts prevent and combat IUU Fishing, namely efforts to prevent, and take action.

Musical folklore as a tool for social-ecological change in the Colombian Caribbean

Large herbivorous fishes, such as parrotfishes, play a critical role in coral reef ecosystems by limiting the coverage of macroalgae. Yet, in the Colombian Caribbean, parrotfishes are being increasingly targeted for human consumption as the demand for fish increases with tourist numbers. The Colombian Caribbean is dominated by Afro-descendant communities, and music is a deeply rooted form of expression and communication. ‘Champeta’, the local music folklore, is heard at all times of day and danced continuously in the islands off the coast of Cartagena. We conducted a survey of local tourist and fisheries stakeholders to characterise the parrotfish fishery, and designed a contextualised awareness-raising campaign of the ecological role of parrotfish and the need for management in the Islands of the Corales del Rosario and San Bernardo National Park. In doing so, we test if Champeta could be used as a mechanism for social-ecological change in Caribbean coastal communities in the context of coral reef conservation. Locals were engaged in every aspect of the campaign, especially with the song, as the campaign was a process rooted in their culture, interests and idiosyncrasies. Surveys of restaurants illustrated the size of the fishery and the extent of misinformation surrounding the consumption of parrotfish by tourists. We found that both locals and tourists held misconceptions about the ecological role of parrotfish and were supportive of efforts to protect them.

Integration of geospatial technologies with multi-criteria decision analysis for aquaculture land suitability evaluation: The case of Fincha'a River Sub-basin, Western Ethiopia

Assessment of physical land suitability for aquaculture is a prerequisite for promoting fish farming and enhancing food security as increase in global population and fish demand is tremendously rising. In addition, our country is also riches in enough water resources and conducive environments. Despite these facts, the vast majority of the local communities in Ethiopia are not benefited from aquaculture due to limited information and infrastructures. This study intended to assess land suitability for aquaculture using geospatial techniques in Fincha'a river sub basin, western Ethiopia. In the present study, slope, river, road, market, land use land cover (LULC), soil types, land surface temperature (LST), rainfall, lakes and reservoirs were performed using multi criteria Evaluation (MCE) based Pairwise Comparison Matrix to evaluate land suitability for aquaculture. The results revealed that, about 51.4km 2 is highly suitable, while 843.5km 2 categorized under moderately suitable. About 1483.5km 2 were categorized under marginally suitable, while 56.5km 2 is not suitable for aquaculture. Based on the result, we recommend that, community awareness is required to utilize maximum potential of aquaculture farming, that may contribute towards poverty eradication and food security in Ethiopia. • Warm area and wetland areas were highly suitable for fish farming. • Analytical hierarchy process is a powerful method to generate land suitability for aquaculture. • Land suitability assessment can indicate the potential of particular land for different purposes. • Utilizing maximum potential of aquaculture farming, that may contribute towards poverty eradication and food security in Ethiopia is forwarded.

Response of Blood Glucose of Brek Fish (Puntius Orphoides) on Stocking Density Stress

This research was conducted with the aim to evaluate the performance of blood glucose of brek fish (Puntius orphoides) in response to stocking density stress. Fish weighing an average of 2.21 g with a weight of 27 individuals were given stocking density stress by inserting them into 9 cylindrical containers of 200.96 cm2 width and 3 L volume of peat water with stocking differently for 72 hours. These stocking density treatments are A (2 fishes/0.02 m2), B (3 fishes/0.02 m2) and C (4 fishes/0.02 m2) with three replicates. Blood glucose collected from 1 fish per container at 72 hours. The preliminary test was conducted to determine the oxygen demand of fish through the oxygen consumption level test which can then be calculated oxygen demand from the fish in accordance with the density used. The average value of blood glucose levels of brek fish that were given the stress of stocking density 2 fishes / 0.02 m2, 3 fishes / 0.02 m2 and 4 fishes / 0.02 m2 tends to be low, that is 53 mg / dL, 52.67 mg / dL and 49.33 mg / dL respectively. The response of blood glucose to stocking density stress results in stocking recommendations for culture brek fish ranging from 100-200 fish / m2.

Are Chilimira Fishers of Engraulicypris sardella (Günther, 1868) in Lake Malawi Productive? The Case of Nkhotakota District

An ecological shift has populated Engraulicypris sardella as a livelihood and economic drive among fishers in Malawi. However, the paucity of biological information regarding E. sardella limits the effective monitoring and sustainable management of the fishery. This has created a heavily invested fishery in terms of the effort put into fishing, but it is poorly managed. Moreover, the current production capacity from the fishery has a negligible impact on lessening the shortfall of the national fish demand, indicating its underperformance. Therefore, the productive efficiency of Lake Malawi Chilimira fishers in exploiting E. sardella was analysed. A multi-stage sampling technique was used to sample 355 Chilimira fishers between July and October 2021. Results from the translog stochastic frontier model revealed that Chilimira fishers had an overall mean technical efficiency of 60% that ranged between 21% and 92%. This indicates that Chilimira fishers are 40% technically inefficient in exploiting E. sardella. The fishing inputs of bunt area, light emitting diode (LED) bulbs, and mesh size significantly contributed to technical efficiency, whereas boat size, fishing depth, number of hauls, and mosquito net lining significantly reduced the technical inefficiency. On average, the Chilimira fishery is operating with increasing returns to scale with bunt area, the quantity of fuel (litres), and the number of LED bulbs having positive input–output elasticity. This means that new developments in the fishery, including LED bulbs, increased bunt area, and boat size, are key factors that will improve fishing efficiency for sustainable fishery exploitation. In contrast, illegal fishing units of small bunt mesh size and mosquito net lining at the bunt threaten the sustainability of the fishery. It is, therefore, important that relevant stakeholders put policy measures in place that promote sustainable fishing effort approaches in exploiting the virgin offshore fishery to maximise catch.

Small pelagic marine fisheries for food sovereignty? The case of the dagaa fishery at three coastal sites in Tanzania

To implement effective ocean governance, development of policies and management strategies needs to incorporate input from communities that will be impacted by the decisions. People engaging in small-scale fisheries and aquaculture mobilize themselves in anticipation of various challenges, for example, food sovereignty. Food sovereignty is the right for people to access healthy and culturally appropriate food that is produced through ecologically sound and sustainable methods. Little attention has been paid to documenting and understanding the struggles and efforts of small-scale fishers to ensure their own food sovereignty. In the Western Indian Ocean region, and Tanzania in particular, there has been a limited number of initiatives among coastal fishers that seek to transform food systems. To better understand these initiatives, this study was designed to examine collective actions undertaken in pursuit of food sovereignty among small pelagic fishers at three landing sites on the coast of Tanzania. Collection of primary data involved a survey of 206 individuals, 25 key informant interviews, 3 focus group discussions and participant observation. Secondary data was also collected from official fisheries records and published materials to supplement the primary data. The study revealed limited current capacity of the small pelagic fisheries to satisfy local demand of fifish for food security and sovereignty purposes due to increased fish trade supplying markets beyond the study sites. The prospects of satisfying an increasing fish demand from existing production systems are limited. Small pelagic fisheries need to be linked to the global food system through appropriate mechanisms to allow them to contribute meaningfully to food security and sovereignty.

The seafood basket: Application of zero-inflated model to fish count purchase

The study analyzed demand for fish in the United States by the number of species purchased from a basket of species, rather than the usual approach focusing on one single species. The basket includes largemouth bass, hybrid striped bass, bluegill, walleye, yellow perch, rainbow trout, Great Lakes whitefish, lake trout, barramundi, and tilapia. These results largely confirm that consumers purchase different fish species or a combination of them from time to time and that consumers pay little attention to green factors such as sustainability, 3rd party certification and hormone-free when purchasing seafood. It appears that the effects of green credence attributes may not apply generically to a collection of fish or that the utility of green characteristics to seafood demand may be declining. As for production systems, although a higher percentage of consumers indicated preference for wild-caught fish, the importance of farmed fish to them was found to increase fish purchased.

Analysis of Procurement and Demand for Raw Materials of Dried Fish Making Business in Bengkulu City

This study is intended to analyze the source of fresh fish and the quantity of fresh fish used in the business of making dried fish in Bengkulu City and analyze what factors affect the quantity of demand for fresh fish in the business of making dried fish in Bengkulu City. This research was conducted from January to February 2022 in Bengkulu City, more precisely, Sumber Jaya Village, Kampung Melayu District. The research location was determined purposively, and 86 dried fish makers were selected using the census method. The data used are primary and secondary, and the data analysis used is qualitative and quantitative. Sources of raw materials in dried fish are divided into three: self-catch, buy, and self-catch and buy. The largest percentage of sources of raw materials is to buy, where the place to get the most comes from fishermen directly. The quantity of raw material used is 10,563 Kg per production process. The factors that partially affect the quantity of demand for fresh fish by dried fish makers are the price of ice and the dummy of the business scale at the 95% confidence level.
