  Citation × Citation Citation Abstract Copy Title: What is the demand for farmed fish on the European markets? Author: Mariojouls, Catherine, Girard, Sophie This paper analyses what are the potential outlets on European markets for new farmed fish. In the first part, the main striking features about the structure and evolution of the European fish trade over the last decade are presented. The analysis of fish imports and exports provides comprehensive data to characterize the EU fish demand per commodity categories, per species groups, per country, and to estimate price trends for both wild and farmed fish imports. Then, the second part is dedicated to an in-depth analysis of the fresh fish trade, as main outlet for farmed fish. The evolution of the balance trade for the main species groups showing a deficit (salmon, gadoids, other demersal fish, completed by an analysis of the price segmentation of fish imports, highlight the substitution phenomena between farmed and wild fish which occurred over the last decade, while providing an assessment of the fish demand for the different market segments. These results are utilized to analyse the potential outlets on European markets for new farmed species issued from an aquaculture diversification, taking into account the increasing competition from well-established and concentrated fish farming industries (salmon, seabass and seabream), as well as the more recent introduction of low-priced freshwater tropical fish (ex. pangasius). A particular attention is paid to the red drum (Sciaenops ocellatus), a tropical marine fish farmed in the French overseas territories. Future prospects for farmed fish diversification are also discussed as regards the consumer expectations towards image and quality attributes (including environmental).

  Citation × Citation Citation Abstract Copy Title: The Trade Liberation and Fish Consumption Author: Honkanen, Asmo, Setälä, Jari, Saarni, Kaija Finland became a member of the European Union (EU) in 1995. After that the food market has changed radically. At the same time the eating away from home has become increasingly common. The aim of this paper is to describe the development of fish consumption in the Finnish catering service sector. The focus is to evaluate the period during rapid market changes. The estimation of fish consumption was based on a statistical sample and the data was collected in 1988, 1991, 1994 and 2005. It was found that the fish consumption has increased 30 per cent during the last ten years. The growth is exclusively based on imported fish. All types of imported fish products were used for meals more than earlier, but the consumption of fresh fish products has grown most extensively. The consumption of salmon and salmon trout increased most, while domestic caught Baltic herring is considerably less important than earlier. The frequency of serving fish meals has also increased. The abolition of national trade restrictions on fresh fish has inevitably had an impact on the consumption of fish in the catering sector.

  Citation × Citation Citation Abstract Copy Title: Co-management and Labor Stickiness in Fishing Communities: Determination of the Optimal Number of Vessels Author: Lee, Yao-Hsien, Chuang, Ching-Ta Year: 2001 In the recent years, resource depletion of inshore and coastal fisheries has seriously impacted Taiwan. Local fishing communities’ economic profits in these fisheries have declined and resulted in lower earned incomes for the fishermen. These phenomena have lead many scholars, government agencies and fishing communities to evaluate the optimal number of operating vessels in these fisheries. This study has explicitly applied the concepts of community-based co-management, fish market concentration and labor stickiness to an economic model that can be used to determine the optimum number of fishing vessels in a fishing community. One corollary of this approach is that we modify the traditional assumption regarding labor mobility in a fishing community and explore here how labor stickiness to the extent that it exists in Taiwan’s fishing communities might bias traditional fishing management policies and influence the determination of optimal number of vessels. In addition, the Herfindahl index (H), which measures the degree of concentration in the structure of a fishery market, will also affect the final determination of the optimal number of vessels. Results suggest that when there are no labor mobility barriers, then with flexible fishing operation costs, the optimal number of vessels and the fish stock would be smaller. Larger values of H (i.e., Herfindahl index) and greater differentials in the fishing efficiency index in the fishing community also result in relatively fewer vessels and fish stock. Finally, as to the impacts of changing fish stock growth rate and fish price on the optimal vessel number and fish stock are also discussed.

  Citation × Citation Citation Abstract Copy Title: Simulation Model Evaluation of Some Fisheries Balance Indicators Author: Scott, Robert, Sampson, David Chronic overcapacity has been identified as a major cause of the overfishing of Europe’s fish stocks and the poor economic performance of the European fishing fleets. Mechanisms are needed to ensure that the capacity of European fishing fleets remain proportionate to available fish stocks. To that end, the European Commission developed “Guidelines for an improved analysis of the balance between fishing capacity and fishing opportunities”, which specify a minimum set of fleet-based technical, biological, economic, and social indicators that purportedly measure the balance between fishing fleets and fish resources. A bioeconomic simulation model was developed to assist in the evaluation of some of these balance indicators. The model is age-structured, like standard single-species stock assessment models, but accommodates multiple independent fish stocks that are harvested by multiple independent fishing fleets. The fish stocks occupy multiple spatial regions with diffusion of fish between regions. The fishing fleets choose where and how to fish based on anticipated profits. Randomness is included in the simulated system in the annual fish recruitments and their spatial distribution. The model was used to generate a series of balance indicators that were then compared against the true conditions in the simulated fisheries to evaluate whether the indicators provide accurate signals of system status. The simulations showed that randomness in recruitment propagates directly into randomness in the balance indicators implying that it will be difficult to detect meaningful signals from any short time series of balance indicator values.

  Citation × Citation Citation Abstract Copy Title: International fish trade and fish product security in Viet Nam Author: Kim, Anh Nguyen Thi, Hien, Thi Tran, Petersen, Elizabeth In 2006, Viet Nam’s fishery sector contributed about 6.1 percent to the GDP of the country and the value of aquatic products in export turnover was about US$ 3.3 billion. This accounted for 9-10 percent of the country’s total export value (MOFI/USDAFAS, 2007). Home consumption of fish has increased from 11.8 kg per capital year in 1993, to 13.5 kg per year in 1995 and is now estimated at more than 19 kg per year (FAO/MOFI, 2003). Fish is the most important source of animal protein contributing 40 percent to the total animal protein intake, and is supporting the people’s food security (MOFI, 2007). This paper shows how international fish trade impacts on fish product security in Viet Nam and presents ideas to improve fish product security for domestic and overseas markets. It focuses on how the Viet Nam Government can influence domestic fish product security in the following ways: 1) policies, 2) support activities contributing to fish security and sustainable development, and 3) encouraging international cooperation in the sector of fish product security.

  Citation × Citation Citation Abstract Copy Title: Simulating the Effect of Seasonal Fishing Moratorium on the Pearl River Estuary Coastal Ecosystem for Fisheries Strategies Exploration Author: Failler, Pierre, Duan, Lijie, Christensen, Villy, Liu, Yu, Li, Shiyu, Moreau, Jacques, Wang, Ying The coastal ecosystem of the Pearl River Estuary (PRE) has been overfished and received a high level of combined pollution in the past decades. The fisheries stock assessments have shown a declining population and have led to a number of management measures, including fishing moratorium. This study evaluated the effect of the fishing moratorium on the sustainability of PRE fisheries through an ecosystem approach. Then, a series of 100 years dynamics simulations were examined in light of five scenarios on the basis of the 1998 Ecopath model to explore better strategies on the fishing moratorium. S0: the present fishing moratorium continuation, S1: No fishing moratorium executed, S2: extending the duration of the moratorium (i.e., 1 June to 1 September), S3: banning all fishing operations in the moratorium season, S4: No fishing moratorium executed but reducing the fishing effort of all fishing gears by 50%. The results show that the fishing moratorium did benefit the ecosystem protection. Comparative analysis among different scenarios indicates that the largest increase (28.0%) in the fish stocks could be obtained in S4. Moreover, it incurred an increase (43%) in total landings. There seemed to be no differences between S0 and S3.

  Citation × Citation Citation Abstract Copy Title: Effect of Trade and Agriculture Policies on Fish Trade and Production in Nigeria Author: Alabi, Reuben Adeolu, Erie, Otasowie Gladys The fishery sector is important in Nigeria’s development matrix. The sector not only provides employment for the citizens but also contributes more than 40% of animal protein consumed by average Nigerian. However, over the years the role of providing animal protein for the populace dwindled to the extent that fish demand outweigh fish production, which created trade imbalance. In order to reverse decline in fish production and curtail fish imports, Government of Nigeria put up agricultural and trade policies to boost fish production and move Nigeria toward self sufficiency in fish. In this study we examined if these policies have influenced fish production, import and export from 1961-2006 in Nigeria. We applied statistical and econometric techniques to relevant time series data generated from Central Bank of Nigeria Statistical Bulletin and Food and Agricultural Organisation Statistical Database. The results of the analyses indicate that SAP has significant effect on fish export, but it has not significantly increased fish production and decreased fish importation in Nigeria. The implication of these findings is that although SAP may increase fish export in Nigeria; because of price incentives associated with SAP. However, price incentives may not be enough to stimulate domestic fish production in Nigeria. The country should think of production inputs incentives as done during Pre-SAP era. The government needs to set in motion other sustainable sector specific strategies and policies in order to fully exploit the potentials of Nigeria’s fishery sector. One of these sustainable strategies is the proper harnessing of aquaculture.

In order to reverse decline in fish production and curtail fish imports, Government of Nigeria put up agricultural and trade policies to boost fish production and move Nigeria toward self sufficiency in fish. In this study we examined if these policies have influenced fish production, import and export from 1961-2006 in Nigeria. We applied statistical and econometric techniques to relevant time series data generated from Central Bank of Nigeria Statistical Bulletin and Food and Agricultural Organisation Statistical Database. The results of the analyses indicate that SAP has significant effect on fish export, but it has not significantly increased fish production and decreased fish importation in Nigeria. The implication of these findings is that although SAP may increase fish export in Nigeria; because of price incentives associated with SAP. However, price incentives may not be enough to stimulate domestic fish production in Nigeria. The country should think of production inputs incentives as done during Pre-SAP era. The government needs to set in motion other sustainable sector specific strategies and policies in order to fully exploit the potentials of Nigeria’s fishery sector. One of these sustainable strategies is the proper harnessing of aquaculture. Close

  Citation × Citation Citation Abstract Copy Title: Modelling adoption of rice-fish systems with fuzzy logic Author: Dang Kieu, Nhan, Udo, Henk, Kaymak, Uzay, Bosma, Roel Most current models analyzing technology adoption are based on a function that assumes farmers make decisions upon utility maximization but ignores cultural or social factors. The traditional production systems of the Mekong Delta were based on floating rice varieties and fish harvested both from rivers and rice fields. Since 1980 the presence of fish in the rice fields decreased and research developed the socalled concurrent rice–fish system to capture the advantages of the synergy. Whether this is a feasible option depends on the farmers’ drives and motives for taking-up the technology. In 2000 we made an inventory among 60 farmers who adopted the rice–fish system in four districts to describe their resources and motivations. In 2006 we repeated this survey among 94 farmers including potential adopters, in order to evaluate the take-up potential of the rice–fish system in the Mekong Delta. Income/person and income/ha of the farm households with a rice–fish system were close to double, while their land area (2.5ha) was not significantly larger than those farms without a rice–fish system (1.95ha). Usually farmers integrating also pigs and fish had the smallest land area. The farmers’ non-adoption of the rice–fish system was mainly due to low availability of capital and land, and to inappropriate location of the field in relation to the homestead, water availability, and agro-ecological conditions. To create space for more upland crops was an important argument for the construction of a rice–fish system. Modeling confirmed that under appropriate agro-ecological conditions the take-up of rice–fish systems can be stimulated by increasing know-how on fish and on system component integration. The sensitivity of the fuzzy logic simulation did not confirm the importance of land size and wealth ranking for the take-up.

  Citation × Citation Citation Abstract Copy Title: DISPLACE: a dynamic, individual-based model for spatial fishing planning and effort displacement: Integrating underlying fish population models Author: Nielsen, J. Rasmus, Bastardie, Francois, Miethe, Tanja We previously developed a spatially explicit, individual-based model (IBM) evaluating the bio-economic efficiency of fishing vessel movements between regions according to the catching and targeting of different species based on the most recent high resolution spatial fishery data. The main purpose was to test the effects of alternative fishing effort allocation scenarios related to fuel consumption, energy efficiency (value per litre of fuel), sustainable fish stock harvesting, and profitability of the fisheries. The assumption here was constant underlying resource availability. Now, an advanced version couples the vessel model to selected size-based population models and considers the underlying resource dynamics in the distribution and density patterns of the targeted stocks for the cases of Danish and German vessels harvesting the North Sea and Baltic fish stocks. The stochastic fishing process includes direct and local depletion by stock that is specific to the vessel catching power, which is proportional to the encountered size-based population on the visited ground and is based on stock assessment and research survey data. The impact of the potential fishing effort displacement by vessels on the fish stocks, with resulting fishing mortality, and the vessels’ economic consequences are evaluated on high spatial and seasonal disaggregation levels by simulating different individual choices of vessel speed, fishing grounds and ports. All tested scenarios led to increased overall energy efficiency, except for the fishing closures that increased fuel consumption and costs for most of the vessels due to increased travel distance. On an individual scale, the simulations led to gains and losses due to either the technical interactions between vessels exploiting the same stocks or to the alteration of individual fishing patterns. We demonstrate that integrating the spatial activity of vessels and local fish stock abundance dynamics allow for interactions and more realistic predictions of fishermen behaviour, revenues and stock abundance.

  Citation × Citation Citation Abstract Copy Title: The mixed bless of modern fishing technology Author: Skonhoft, Anders This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that more modern fishing technology has a two-sided profitability effect, and where the direct, short-run, positive effect is counterbalanced by a negative, long-run, indirect effect that slows down the stock growth and increases the harvesting costs. In the steady state, it is shown that more modern technology dissipates the rent under already high exploitation pressure, while the opposite occurs if the fish stock is initially little, or moderately, exploited. This is the mixed bless of modern fishing technology. Title: The mixed bless of modern fishing technology Author: Skonhoft, Anders This paper formulates a simple biomass growth model of a fishery.

  Citation × Citation Citation Abstract Copy Title: Why and When Joint 'Exploitation-Ecosystem Dynamics' Models Should be Used Author: Laloë, Francis Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics is represented “conditionally to” fishing mortality. This mortality must be therefore primarily defined in reference to the definition of the resource Such models can be used to make stock assessment from historical data and to find which fishing mortality values could lead to some objective that can be some optimal or acceptable situation. If the values of fishing mortality can be decided by some unique institution, this knowledge of “best or acceptable mortality values” is of great interest for decision support. If not, it becomes insufficient to identify which decision of which institution could lead to obtain some given set of fishing mortalities. This situation may arise if there is a high number of fishing units belonging to various fishing fleets that may decide to generate fishing mortalities distributions among several available possibilities, according to their own interest. Examples of such problems will be presented from a Senegalese case study where several fishing fleets harvest on a common multispecies resource. Some other examples will be given from case studies identified in the context of the program ECOST with the development of a generic model which represents the joint dynamics of fishing activity and resource.

  Citation × Citation Citation Abstract Copy Title: The Role of Fish-Markets in the Icelandic Value Chain of Cod Author: Klemensson, Ólafur, Gestsson, Helgi, Knútsson, Ögmundur The two main pillars of the Icelandic fishing industry are the large vertically integrated fishing companies and the SMEs, specialised in fishing, producing or marketing. In order to understand how they are able to function side by side and at the same time secure a relatively high value added for the domestic part of the Icelandic value chain of cod, a closer look at the functions and operations of the Icelandic fish markets is needed. In the authors’ recent studies on structural changes in the fisheries value chain in Iceland from 1990 to 2007, six dissimilar main operational strategies were identified. Common to all of those was the need for an efficient use of the Icelandic fish markets. Three distinctive effects of fish markets were identified: firstly, specialisation, where large and small fisheries companies use the fish markets to swap or sell all other species than needed in their specialised production (usually to SMEs producers specializing in those species); secondly, to gain stability in sourcing, where companies source raw material from the fish markets and top-up when there is lack of certain species (or sizes) from the companies’ own boats and; thirdly, the market driven function or effect (market orientated value creation). To study this facilitating and supporting effect of fish markets on the on the progress of the Icelandic fisheries sector further, the focus is now the importance of fish markets from the time of their establishment in Iceland in 1987. The research is based on semi-structured and in-depth interviews with managers of a number of Icelandic fishing and processing companies and is a part of an ongoing research on the value chain structure and on organisational- and productivity changes in the Icelandic fisheries sector.

More than 70% of the total Thai fishing vessels had been using this fishing gear, as well as push net which was restricted targeting for demersal resources. Due to the 2.5 cm fine mesh size, juvenile economic species had been caught and sold as trash fish.

Von Bertalanffy growth function and length-weight relationship were employed in estimating the economic losses of these by catches of juvenile economic species. The loss of these economic species was estimated to be 10.82% of the usual fishing cost in case of anchovy purse seiner while it could be as high as 25.55% in case of light luring anchovy purse seine. For otter board trawler, this loss was estimated as high as 90.42% of the fishing cost, while they were 19.64% and 816.84% in case of push netters.

Even after six decades of planned development nearly 62 per cent of the fisherfolk families do not possess crafts. Resource constraints coupled with absence of fishing and other related infrastructures in most of the fishing villages compel fishermen households to migrate to earn their livelihood. Migrant fishermen formed a new village and follow simple method of fishing, which are eco-friendly, economical in the use of fuel and gears. Their responsible fishing is useful for fishing without any by-catches and wastage of marine resources. With this theoretical background, this paper is framed in such a way to analyze the factors that contribute to the transition of small-scale fisheries to sustainable and responsible fishing in Tamil Nadu, India. Factors which hamper small-scale fisheries development have been discussed.

Most of the consumers responding prefer to eat fish, although the per capita consumption of fish was stagnant. Some demographic factors and consumer preference for food attributes were identified to affect preferences for fish. The older, white collar worker, those who believed in the religion of Daoism, those who paid more attention to food nutrition, to food taste, and/or to food quality had higher odds of preference for fish, while the unmarried, the female, those who believed in the religion of Yi-Guan-Daoism, those who lived in eastern, middle, or southern Taiwan had lower odds of preference for eating fish. The results implied that fish had an overall good perception in Taiwan. However, the fact that younger consumers and/or female consumers had lower odds in preference for fish implies a risk for future development. Further exploration of characteristics of food preference of these groups may be needed to illuminate information of marketing and product development for the fishery industry to further development.

The aim of this paper is describe how much fish consumption varies between different types of catering outlets and what is the importance of kitchen personnel’s opinions to fish consumption. The data was collected in 2005 with telephone survey in interviewing persons, which were involved in managing or procuring operations in the outlets. The results showed that the fish consumption per served portion varies considerably between different outlet types. The consumption was two times higher in restaurants or hotels than in schools or hospitals. Moreover restaurants purchased most of fish as fresh whereas public kitchens preferred frozen products. Staff’s opinions concerning fish price or origin had impact on the fish consumption. However opinions about healthy aspects or the risk of environmental pollutants did not have impact of fish consumption in catering outlets.

The consumption was two times higher in restaurants or hotels than in schools or hospitals. Moreover restaurants purchased most of fish as fresh whereas public kitchens preferred frozen products. Staff’s opinions concerning fish price or origin had impact on the fish consumption. However opinions about healthy aspects or the risk of environmental pollutants did not have impact of fish consumption in catering outlets. Close

  Citation × Citation Citation Abstract Copy Title: Indicators for Ecosystem Externalities in Fishing Author: Andersen, Ken H., Vestergaard, Niels, Ravn-Jonsen, Lars Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem. We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon general ecological principles and is calibrated to the North Sea. Two fleets are considered: a `forage fish’ fleet targeting species that mature at small sizes and a `large fish’ fleet targeting large piscivorous species. Based on the marginal analysis of the present value of the rent, we develop a benefit indicator that explicitly divides the consequences of fishing into internal and external benefits. This analysis demonstrates that the forage fish fleet has a notable economic impact on the large fish fleet, but the reverse is not true. The impact can be either negative or positive, which entails that for optimal economic exploitation, the forage fishery has to be adjusted according to the large fish fishery. With the present large fish fishery in the North Sea, the two fisheries are well adjusted; however, the present combined exploration level is too high to achieve optimal economic rents.

To our knowledge, no approach has focused on the perceived impact of fishing on the halieutic resources. More precisely, we seek to analyze the perceived impact on the marine environment of fishing activities in 5 European countries. Basing on a European sample, we examine the determinants of individual perceptions of the fishing impact on halieutic resources. Moreover, in order to put forward common and national specificities, we estimate the perceived impact for the five countries separately. We evidence that sociodemographic characteristics do not show significant effects on the perception except for age where young people seem to be more sensitive to this ecological issue. However, the perceived impact of fishing on halieutic resources is positively associated to the extent of fishing activities, whereas pollution and global warming surprisingly do not exert significant influence: this result implies that only fishing activities are perceived as having an impact on the biomass. In addition, our estimates show that the subjective impact on halieutic resources is positively influenced by the perceived level of fishing regulation, while an increasing time spent in seaside reduces it. Finally, we show the existence of important national differences in the way in which individuals apprehend the impact of fishing activities on the marine environment. Whereas Italy occupies an intermediate position, Denmark and France are characterized by a more favourable awareness of the perception of the fishing impact than Belgium and the Netherlands.

  Citation × Citation Citation Abstract Copy Title: Economic Impacts of Catch Allocation from Commercial Fishery to Recreational Fishery in Hawaii Author: Sharma, Khem R., Leung, PingSun Year: 2001 The recent expansion of the longline commercial fishery has heightened the conflicts among various fisheries in Hawaii, especially between longliners and non-longline commercial (troll and handline) and recreational fishing boats. The recent court ruling against longline fishing on some waters around Hawaiian islands may provide an impetus for the expansion of the non-longline commercial activities, which in turn may give rise to conflicts between non-longline commercial and recreational fisheries. This study examines the economic impacts of the allocation of catch from one nonlongline commercial fishing trip to recreational fishing using the 1992 input-output model of the state of Hawaii. The results show that the total impact on value added per unit of fish landed is greater for recreational fishing than commercial fishing, while total impacts on income and employment are greater for commercial fishing. When forward-linked trade and distribution services of final demands are also included, total value added, income, and employment impacts are all higher for commercial fishing and hence net impacts of allocation of the commercial fishery to the recreational/expense fishery are all negative. Furthermore, when the effects of an equivalent decrease in personal consumption expenditures (PCE) of other sectors due to an increase in expenditures in recreational fishing are also included, total losses on value added, income, and employment become more significant. However, relative to direct impacts indirect impacts on value added, income and employment are higher for recreational fishing than for commercial fishing such that the corresponding net indirect effects are positive in all cases.

  Citation × Citation Citation Abstract Copy Title: Markets, Marketing and Production Issues for Aquaculture in East Africa: The Case of Uganda Author: Jagger, Pamela, Pender, John Year: 2001 Aquaculture is currently responsible for an insignificant proportion of total fish production in Uganda. However, given increasing demand for fresh fish in urban and peri-urban areas, and threats to the supply of fish from natural catch fisheries there seems to be a potentially strong market for fish and fish products produced by aquaculturalists. Small-scale fish farmers that are relatively close to markets or all season roads, and can supply consistent and high quality produce, will have the widest range of marketing opportunities, and will likely be within the scope of potential traders and intermediaries that deliver fish to markets. Fish farmers that are not close to roads, or produce unreliable quantities and quality of product may face high transactions costs of marketing their product, decreasing net returns to production. We also find that significant on-farm labor, and access to input markets are important factors leading to positive net returns to fish production. Areas with high population density and relatively low wage rates will be well suited to labor intense aquaculture. We conclude that aquaculture development has good potential in certain areas of Uganda and should therefore be pursued as a potential development pathway. However, policy makers should consider the importance of the price of fresh fish relative to the cost of labor, as well as other factors including the importance of smallholder credit and access to extension services when directing investments in aquaculture technology.

  Citation × Citation Citation Abstract Copy Title: Structural Performance of Artisanal Fish Marketing in Ondo State, Nigeria Author: Ojo, Sylvester Oluwadare, Oparinde, Lawrence Olusola Fish is an important source of protein which is highly needed for human beings to experience necessary growth and development. This is the reason for the phenomenal rise in the consumption of fish in order to meet up with the body nutritional requirements. Therefore, marketing of this source of protein is inevitable as its distribution depends largely on the structure of the marketing system. This study examined the structural performance of artisanal fish marketing in Ondo State, Nigeria. Data collected from 250 artisanal fish sellers selected using multistage sampling technique were analysed using descriptive statistics, marketing and gross margin, Gini coefficient and Lorenze curve analyses. The results showed that artisanal fish marketing was profitable with a mean net return of N137.10/kg ($0.85/kg). The estimated value of the Gini coefficient determined was 0.64, indicating the presence of inequality in the share of the artisanal fish market in the study area. It was realized that all the respondents in the study area, mentioned poor transport network, high transport cost, inadequate fund and inadequate storage facilities as major problems confronting artisanal fish market in the study area. Therefore, programmes that will improve fish marketing should be organized for fish marketers by the relevant government parastatals, extension workers, Non Governmental Organizations and the artisanal fish marketers should be sensitized on the formation of better organized fish marketing cooperative societies where they can solve some of their problems themselves.

Author: Janmaat, John, Ruijs, Arjan In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries model can introduce hysteresis impacts, impacts that affect both the evolution of the fish stock and the fishery harvesting it. We demonstrate that harvest and effort taxes are not equivalent instruments for controlling this externality. We also show that if the fishery is sufficiently degraded, it may not be optimal to move the system back to a healthy environment. Title: Fishing in a Shallow Lake: A Case for Effort Controls?

The paper proposes some methods for estimating the value of commercially exploited fish stocks and the cost of exploiting them. The paper uses data on some important fish stocks in Icelandic waters to give examples of results from using the proposed methods and indicate the degree of uncertainty involved in the estimations. The values of the fish stocks are estimated by using the prices of share quotas and by using direct estimations of the sum of discounted expected future profits. Estimations of fixed-price value of the fish stocks are also discussed.

  Citation × Citation Citation Abstract Copy Title: New Paths in the Raw Material Flow Author: Bendiksen, Bjorn Inge, Dreyer, Bent The Norwegian fish processing industry is an old industry and organising of production has been solved by fishing vessels catching fish and selling it fresh directly to processing plants located on shore close to the richest fishing areas. During the last decade an increasing part of the catch has been frozen on board. This change in supply, from fresh to frozen fish, has triggered investments in new cold storage plants along the Norwegian coast. These changes are about to change the entire market for raw materials and also the fish processing industry itself. Technological changes among the suppliers have created a totally new competitive position for the processing plants. In the new competitive setting one of the most valuable resources among the processing plants, i.e. a location close to fishing areas, is devaluated. The bargaining power to the local processing plants is decreased mainly because new entrants have achieved easier access to the local raw material market.

  Citation × Citation Citation Abstract Copy Title: A Stackelberg Analysis of the Potential for Cooperation in Straddling Stock Fisheries Author: Flaaten, Ola, Long, Le Kim To ensure the long-term conservation and sustainable use of straddling fish stocks, the 1995 United Nations Fish Stock Agreement calls for the establishment of regional fisheries management organizations to manage such stocks. This paper studies the potential for cooperation in straddling stock fisheries when the cooperative coalition of countries acts as a Stackelberg leader against the remaining singleton countries. It is demonstrated that an increase in the cooperation level leads to an increase not only in the steady-state fish stock, but also in the total rent of the fishery. Further, the outlook for cooperation is better within the Stackelberg game, where the cooperative coalition acts as a leader, than in the Cournot game. At the stable equilibrium of a Stackelberg game, not only is the steady-state fish stock higher, but also the total resource rent, participants’ rent and non-participants’ rent are higher than those of the Cournot–Nash stable equilibrium. The new-entrant issue is also a problem for the conservation of the fish stock in the Stackelberg game. According to the present research, the prospects of cooperation in utilizing a straddling fish stock are not unlikely if the cooperative coalition acts as a leader. This is an important implication for policymakers when discussing an agreement for establishing a regional fisheries management organization (RFMO) to manage a straddling fish stock.

  Citation × Citation Citation Abstract Copy Title: Motivation to consume fish (seafood) in Vietnam Author: Olsen, Svein Ottar, Nguyen, Tien Thong This study extends Theory of Planned Behavior (TPB) to investigate the motivation to consume fish in a representative survey of Vietnamese individuals. The emperical study is based on using the structural equation approach to test construct valitidy of measures and the emperical fit of theoretical model. The results show that the TPB is signficantly applicable to the Vietnam situation. The 23% of the variation of eating fish frequency is signficantly explained by motivation and perceived behavioral control. The motivation to consume fish as measured by intention is signficantly determined by subjective norms and attitude toward fish as meal; the two constructs explained for 35% of the motivation variation. At the specific level, the study found that negative affect, perceived quality and price are significant indicators that explains for 60% of the variation of the attitude construct; perceived price, time using to cook and prepare fish as meal and availability of fresh fish are important factors explaining for 63% of the variation of the perceived control over fish consumption. As one of the first attempts, the study provide some managerial suggestions for seafood sector to expand the domestic markets and also raise some recomendations for future research.

  Citation × Citation Citation Abstract Copy Title: The Business of Fishing: Queensland, Australia 1997-98 Author: Burger, Elisa, Bibby, Jeff, Switala, John, Taylor-Moore, Noel, Dexter, John, Norris, Wez, Henderson, Tracy Year: 2001 Commercial fishing in Queensland, Australia, involves a diversity of fishing activities such as trawl, line, net and crab. Due to a complex licensing arrangement (Licence Packages), most fishers are endorsed to operate in more than one fishery providing flexibility for commercial fishing operations. The aim of this paper is to document the economic performance of Queensland’s fishing businesses based on a comprehensive survey. Business performance was analysed using the following economic indicators: receipts, costs, boat operating surplus, boat business profit, gross returns index, rate of return to capital and fishery rent. The analysis characterised fishing businesses based on scale of operation, type of fishery accessed, degree of specialisation and geographical location of fishing business base. Each group had differing levels of economic performance: at least half of the surveyed fleet were not covering all of their economic costs. Fishers were asked their view on a range of issues effecting their economic performance and were pessimistic about the viability of the fishing industry and their future.

  Citation × Citation Citation Abstract Copy Title: Accessibility of Aquaculture Products in Thailand Author: Piumsombun, Somying Year: 2001 The paper first reviews the aquaculture sector in Thailand and focuses on the development of freshwater fish. The government has promoted freshwater fish culture mainly to supply domestically. The development policies that influence markets and access have been stated. It then highlights fish consumption by region. As a result of increased demand for freshwater fish, marketing plays an increasing vital role and is left in the hand of private sector. Marketing practices including market structure, marketing channel and marketing margins are analyzed and discussed. It is found that the private assembly markets as well as the retail outlets have been developed significantly to serve the increase in both the supply and the demand of cultured freshwater fish. Marketing margin varies among species. Obstacles to market access is not observed apparently. The shift in production centers close to the big consuming center with high purchasing power in the past two decades may benefit some group of consumer. However, the consumer in other regions can access to freshwater fish through the effective and efficient marketing system. The paper concludes with the discussion and analyzes of future domestic market potential in view of existing and evolving consumption pattern and marketing development, and measures required to realize the potential.

  Citation × Citation Citation Abstract Copy Title: Fishing Versus Farming in a Fresh Water Swamp in Trinidad in the Caribbean Author: Fridie, Marsha L., Pemberton, Carlisle A. Year: 2001 This paper compares the status of fishing to farming in the Nariva Swamp, on the eastern coast of the island of Trinidad, in the country of Trinidad and Tobago. This swamp is one of international significance, since it is a home to the endangered animal, the manatee (Trichecus manatee). Also the swamp has a large population of two aquatic species of economic importance in Trinidad and Tobago - the armored cat-fish or cascadura (Hoplosternum littorale) and the ampulariid snail or black conch (Pomacea urceus). Residents of the area include in their diet the consumption of these species, as well as exploit them commercially. The paper is based on two surveys in the swamp, one was of 99 occupiers of plots, to determine their economic activities and the other survey was of 33 households, to determine the importance of fish from the swamp in their diets. The analysis in the paper showed that farming was now the dominant economic activity in the swamp, both in terms of income received as well as the amount of labor utilized. The residents did consume fish from the swamp, but this fish was not the major source of protein. Poultry and poultry products, especially chicken were the preferred protein sources. Farming was seen as a threat not only to fishing, but also to the native flora and fauna of the swamp and the paper called for urgent studies of the impact of such extensive farming on the ecology of the swamp.

The aim of DOGMATIS was to investigate the questions raised by the use of transgenesis on an animal, and the possible answers in case of application at economic scale. As for socio-economic aspects, we studied the risk of fortuitous imports (see IFET 10), and we studied the perception of the public through two methodologies : (i) consumers focus groups organised in 2007 and 2010 (see IIFET 10), and (ii) 35 comprehensive interviews with economic actors (wholesalers, retailers, supermarkets, fish farmers) and NGO. This poster presents the key-points of our results issued from those interviews. If GM Fish is for all actors a “remote object”, interviewees accept to fully project their reflexion in a possible future situation of the use of transgenetic fish in farms and the arrival on the market. For economic actors, the raised questions are related to their activities but also to general questions, as for those observed in the consumers focus-groups. For NGO, GM Fish are hardly considered specifically, but nevertheless would require positions and actions if present.

  Citation × Citation Citation Abstract Copy Title: Fish Marketing and Food Security in Nigeria Author: Agbebi, Funmilola Omolara Fish is an important source of protein for the middle-class and elites across Nigeria. The handling, processing, and marketing of fish products are essential complementary functions of all food production systems. Additionally, the fish trade offers substantial employment opportunities in many coastal and inland areas where fish is caught. The importance of fishery products and its marketing had always been an important discourse among scholars due to its contributions to Gross National Product and the per capital income of fishermen in Nations with fishing capabilities. In Nigeria, however, given increasing demand for fish, there seems to be a potentially strong market for the product. And markets determine marketing policies. So, markets have to be considered before policy making can start. This study proffer solutions to some key questions in the study of marketing of fish products in Nigeria such as: Key questions on: commodity chains/networks, trader roles, control of market space, market information, credit provision, transportation questions, consumption pattern, food safety regulation, Key questions around legislation, standardization of weights and measures, trader associations, Pricing, the role of traditional authorities, and alternatives to traditional intermediaries/ forms of supply. This paper therefore focuses on fish marketing and food security in Nigeria. Its various stages of development were considered. The study also shows some major findings that will assist policy makers. It also revealed the key roles of storage and processing as main factors aimed at improving fish marketing in Nigeria.

  Citation × Citation Citation Abstract Copy Title: Global Change in African Fish Trade: Engine of Development or Threat to Local Food Security? Author: Lawton, Rebecca, Béné, Christophe Today fish is the most traded food commodity in the World. This situation is not without generating potential issues. On the one hand, fish trade is said to support economic growth processes in developing countries by providing an important source of cash revenue. On the other hand, fish trade is also said to lead to a decline in food security and a decrease in the availability of fish for the local population. In this paper we explore more thoroughly those two opposite views in the specific case of sub-Sahara Africa. For this we consider a range of eight national development indicators that encapsulate both economic and well-being of sub-Sahara countries over the last decade and correlate them against four indicators reflecting the country-specific importance of fish trade, industrial and small-scale fisheries in the economy of Sub-Sahara Africa. Our statistical analysis shows that when sub-Sahara countries’ data are considered at the macro-economic level the fear that fish trade may affect negatively fish food security is not substantiated by any statistical evidences. At the same time the analysis also shows no evidence to support the claim that international fish trade contributes effectively to national economic development and/or wellbeing. The last section of the paper discusses the various possible reasons for this apparent lack of correlation and highlights the respective flaws underlying the two opposite discourse about the role of fish trade in national development and food security.

  Citation × Citation Citation Abstract Copy Title: The Value of Fish Quality Author: Jaffry, S., Pickering, H., Frere, J., Roth, E., Nielsen, M., Wattage, P., Whitmarsh, D. Year: 2001 This paper aims to reveal consumers’ preferences for quality graded fish products based upon existing data on first-hand sales in Denmark. The data represents the value of fish for consumption as a non-differentiated private good. The objective is to measure the welfare gains to society of an increase in “quality” for major fish species. The demand for Quality Extra and quality A-fish is estimated using an Inverse Almost Ideal Demand System (IAIDS-model) as the functional form of demand on first-hand sales data following the European Union established trade norms for quality-grading and sizecategories. Secondly the possibility of estimating changes in consumer surplus as the welfare gained by society of a general increase in quality of landed fish is discussed. However, the estimates on consumer surplus are not yet completed. The model adopted is a pricing model for the implicit price of the characteristic “quality” which necessarily is part of the product i.e. fish for consumption. Today the Danish market for fish does not explicitly state the “quality” of fish in the consumers market. This is generally a credence parameter. There are no objective verifiable standards available to the consumer and this is an element of trust in the word of the fish retailer. This paper shows the first results of adopting a revealed preference model for indirect benefit estimation on existing quality differentiated fish at first-hand sales. We explicitly discuss the assumptions of “weak complementarity” and “derived demand” necessary to run the model.
