Tilapia is one of the fastest growing aquaculture species in the world. It is produced and consumed in all continents and in more countries than most other species, making the market more heterogeneous than for other successful aquaculture species such as salmon and shrimp. This paper investigates the degree of...
Globalisation in the retail sector is transforming food value chains by driving consolidation in the industry and extending supply chains across the globe. Globalisation enables retailers to benefit from economies of scale and cheaper production in foreign locations. However, food markets themselves are increasingly responding to local consumer preferences. In...
Vietnam is in the club of countries gifted with the long coastal line, and strong in marine features accordingly. Fishing operations are artisan characteristic and the management method is primarily open – access. Since the past few years, the yellow fin tuna long- lining fishery has become one sub-sector experiencing...
Fisheries management is complicated in nearly all fisheries by various types of uncertainty. Numerous economics and fisheries science publications prescribe adjustments to harvest strategies in the face of uncertainty. The conclusions and recommendations from this body of work are conflicting in many cases, are often dependent on critical but unrealistic...
As compared to other countries, France has been involved very lately in the discussion about fisheries ecolabelling. Reluctant to adopt the existing ecolabels, the professional organisations, the Ministry of
food, agriculture and fisheries and the European Commission itself tend to create their own label guidelines to take into consideration other...
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...
The majority of monitored fish stocks globally is fully or over exploited, that is, at or below their maximum sustainable yield stock levels. Despite this resource situation international trade in fish products have been increasing for a long time. An export tax on fish and fish products, as an alternative...
The Mekong River Delta plays an essential role to Vietnam’s economy in terms of both rice and fish production. Annual flooding water and a rich level of aquatic resources strongly affect about 10 million
local people, as well as extend beyond the boundaries of wetland itself. Flooding water and wild...
Van Chai are traditional fishing associations in Binh Dinh province, mainly distributing in coastal areas. In spite of experiencing many ups and downs, suffering great impacts of market economic and cultural integration, these villages still exist until now. However, many cultural features of the Van Chai have been gradually lost...
Promoting shrimp culture industry is one of the effective ways to earn foreign currencies and reduce rural
poverty for developing countries. However, there is a question if rising wage rates might be a constraint for further development. Thailand, for example, has established a firm position in the industry, but its...
Outputs and inputs during 1994-2006 in the USA Northeast Multispecies (groundfish) fishery—including days fished for a group of 47 otter trawl vessels fishing out of New Bedford, Massachusetts, USA—were analyzed to test the hypothesis that restricting the annual days-at-sea (DAS) of individual fishing vessels increased Technical Efficiency (TE). The results...
In agriculture there has been a long history of using a levy or an insurance premium to create mutual funds to mediate economic risks to growers due to environmental variability and quarantine pests. In the United States the federal government, through the USDA, continues to underwrite funds (collected by private...
Over the past fifteen years, the market for bluefin tuna has evolved in an attempt to further enhance the economic value of bluefin tuna landings. Historically, the US East Coast has been a major supplier of high quality bluefin tuna to Japan, the primary market for sashimi grade tuna. To...
The aim of this paper was to compare the nutritional value of some low price fish (Sardina pilchardus, Engraulis encrasicholus, Anguilla anguilla, Salmo trutta, Mugil chepalus) to high price fish with high consumption rate (Sparus aurata, Merluccius merluccius, Dicentrarchus labrax).In general, the commercial values of several fish species in Greece...
The potential for achieving sustainable and efficient harvesting of three species of migratory tuna in the
Western and Central Pacific Ocean is examined. The stocks reside in exclusive economic zones (mainly those of Pacific island countries) and in the high seas. Most harvesting is carried out by distant water fishing...
The processing industry is playing an increasingly important role in Vietnam’s overall economy. A study on the restructure in this sector across the Coastal Central South has demonstrated the dominating part that middlemen are taking in connecting the supply, represented by fishers and farmers, to demand, represented by processing enterprises....
Local community in the Mekong Delta is said to be “fish eating society” where 70% of their animal protein relies on fish products. The Mekong Delta contributes more than 60% of total aquaculture production and 40% of total wild fish catch of Vietnam. Among a large number of fishing boats,...
Over fishing is one of the obstacles faced in managing sustainable fishery resources. Even though various management instruments to control fishery resources have been in place, most of the time these instruments are not effective to curb over fishing especially in developing countries where poverty in coastal communities is still...
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...
This paper is focussed upon the marketing implications and adoption responses from a 3 years multidisciplinary Research Councils UK project which has examined the prospects for UK (agricultural) farmers to diversify into production of warm-water tilapia. The proposed production process and product characteristics abound with green credentials, consistent with emergent...
Fisheries are increasingly important in the world with growing demand for fish in China, Western, African and Asian countries. Many people depend on fisheries and will be benefited from fisheries. Many governments took fisheries promotion policies after the 1970s when the UN 3rd Law of the Sea Conference developed. However,...
The year 1990 saw the introduction of individual transferable quota rights to the NZ rock lobster fishery. This paper presents an analysis of the evolution of profitability in five different quota management areas over the period 1990-2001. The bio-economic model of an optimal fishery provides the basis for econometric analysis....
Khanh Hoa, featured by advantageous conditions from both nature and humans, has long enjoyed great potentials for fisheries development. The most immediate evidence can be cited is that the fisheries industry
made significant contributions to the local economic growth during the recent period of 2001- 2006, and impressive figures in...
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...
The Finnish food service outlets can be categorized as commercial foodservice operators, public kitchens
or staff restaurants. 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...
Marine Protected Areas (MPAs) can be considered as one of powerful conservation tools of fishery resource management in the literature. However, due to continuing environmental awareness and mismanagement, the Philippine government has decentralized the power of legislation and management of its MPAs since the early 2000. This encouraged participation of...
Under the reauthorized Magnuson-Stevens Act (MSRA), US fisheries management councils must specify an annual catch limit (ACL) for each managed species and institute accountability measures (AMs) to ensure that actual harvest will not cause the stock to be overfished. While the details of implementation are still being developed, a set...
This paper comparatively examined resource-use and technical (TE) efficiencies of aquaculture farms in the Southwest Nigeria. A total of 160 farms were randomly selected from four states across the region. Econometric applications of the stochastic frontier models provide measure of the farm’s technical efficiency. The results of regressions specified for...
There is growing recognition worldwide that the impacts of fishing on non-targeted components of marine ecosystems should be included in the assessment of fisheries sustainability. This leads to the inclusion of new constraints in evaluations of the long-term bio-economic performance of fisheries. In this paper, we analyze the implications of...
There has been a long-standing interest in local knowledge in fisheries research and management. Much of this interest has been in terms of how local knowledge can be interpreted scientifically and used by fisheries experts and managers. Local knowledge becomes the property of scientists, wrapped up in a format and...
Despite potential advantages of rights-based management over competitive fisheries, there has been significant political resistance to rights-based management from many fishermen, which has slowed the
adoption of rights-based management. This paper explores the concept of voluntary transitions to rights-based
management, under which fishermen may choose between an allocated fishery (with...
The paper analyzes the recent behavior of the Peruvian Anchoveta Sector, the largest single stock fishery in the world. It describes the different phases of boom and contraction that it has undergone since the 1960s, and how the lack of adequate regulation allowed –and even fostered– over-investment in the sector...
Unlike the North and the South where abundance of freshwater, the marine capture fisheries is underdeveloped, the Central Coast, especially South Central Coast with little freshwater fisheries resources, but high amount of shrimps, fishes at sea, thus local fishermen have exploited this resource for living early. Together with this living...
The Social Sciences Branch (SSB) of NOAA’s Northeast Fisheries Science Center (NEFSC) uses economic data to estimate the economic impacts of fisheries regulatory actions. Since 1995, the Northeast Fisheries Observer Program has collected trip cost information from commercial fishing vessels on which observers have been deployed. However, the allocation of...
This paper estimates current resource rents being generated in the Icelandic cod fishery and compares them to the maximum sustainable attainable ones. For this purpose a simple aggregative model of the cod fishery is specified and empirically estimated. It is found that in spite of the cod stock being in...
Although the share of total fish supply which is traded internationally is fairly stable, the patterns of trade flows are in constant change. China and Viet Nam are increasingly emerging as processors and suppliers of value-added products to world markets, but also within the world’s various regions new players are...
Since January 2008, the fishing agreements between the European Union and ACP (African, Caribbean, Pacific) countries have changed to comply with WTO rules and improve the management of the fisheries. However, the poor countries depend perhaps too heavily on foreign aids to impose any management system to the distant water...
This report presents the results of bio-economic assessment studies of the Bohai Sea & the Yellow Sea and the associated fisheries management. The studies, which were facilitated through workshop with the participation of international experts, included fisheries resources rent assessments and causal chain analysis to determine the rent losses in...
In order to provide a rationale and mechanism for implementing responsible fisheries in practice, this paper examines the effect of establishing Regional Fishery Management Organisation (RFMO) with effective enforcement on cooperative possibilities in shared fisheries. The result shows that an increase in cooperation level is a social welfare improvement, and...
The long history of the van chai system of Vietnam began several centuries ago with their establishment mainly in the lower and middle reaches of rivers northern Vietnam and in coastal lagoons in Central Vietnam, whereas those in marine embayments, like Ha Long Bay, and in enclosed coastal areas, like...
A plant community classification was developed describing the comprehensive variation of oak vegetation currently occupying the Willamette Valley Ecoregion of western Oregon. Multivariate statistical analyses were used to classify field collected floristic and habitat data. Field sampling targeted minimally managed, homogenous vegetation stands with a significant oak component occupying at...
Basic research on semantic interoperability is just beginning to address support for spatial data and information. This is clearly important for data portals containing geographic information system (GIS) layers, as well as supplemental information, often with cartographic and decision support tools. Agreements on content/semantic interoperability of these resources can help...
Motivated by a real-world problem, we study a novel setting for budgeted optimization where the goal is to optimize an unknown function f(x) given a budget. In our setting, it is not practical to request samples of f(x) at precise input values due to the formidable cost of experimental setup...
