Pla Tubtim (Oreochromis sp.) was a new fish species for aquaculture in Thailand. It was an improved breeding from tilapia and expected to be a common fish dish for the Thais while being an important source of income earning for fish farmers in this country. Logit model was applied to...
Combating illegal fishing is one of the major difficulties the International Law of the Sea faces. The European Community is aware of this problem and has taken some measures to fight against illegal fishing, amongst which there are those related to the effective exercise of jurisdiction and control of the...
Fishing overcapacity has lead to unsustainable harvesting and rent dissipation in global fisheries. Only government intervention of some kind can lead to a reduction in capacity. If efficiency is the primary objective for the regulator, then the least efficient vessels should be decommissioned. Here we analyze the Swedish fishery using...
In marine resource management, spatial policy instruments, including Marine Protected Areas, are becoming increasingly important. The economic motivation for spatially explicit policy is that renewable resources generate, in addition to the conventionally recognized incentives to over-harvest in the face of insecure property rights, spatial externalities that distort the spatial distribution...
The high ecological, social and economic value placed on Western Australia’s aquatic environment creates a significant obligation on the WA Department of Fisheries to develop and implement appropriate and sustainable resource management strategies for the State's fisheries and fish habitats. Historically, fisheries management in Western Australia has been based on...
In this paper we analyse different econometric procedures of technical efficiency to estimate fishing capacity. These procedures are then applied to the purse seine fishery located in the Gulf of Cádiz. The target species of this fishery has changed quite a lot over the past few years. It used to...
M_ori rights over fishing resources in Aotearoa/New Zealand are being dramatically affected by ongoing changes in legislation and socio-economic factors. Although rights over natural resources were guaranteed to M_ori, the country’s indigenous people, by Article 2 of the Treaty of Waitangi 1840, those rights have subsequently been eroded. Historically, fishing...
Over the past 50 years, most efforts to regulate fishing and conserve our oceans and seas only have had limited success in preventing the on-going problems of over-fishing, degradation of the marine environment, and irreversible loss of marine biodiversity. Ecosystem-Based Management (EBM) of the oceans is an approach that is...
Factors influencing the emergence of collective action are studied using survey data from individual boat owners from Barka, Masn’a and Suwaiq. Fishermen who adopt a cooperative strategy tend to be more risk averse and have high economic dependence on the common property resources. Social identity as a fisherman also appears...
The fish market in Finland has changed dramatically since the removal of trade barriers to the importation of fresh salmon in 1993. Imported salmon has rapidly captured markets from domestically produced salmon trout. Another clear trend has been increased concentration at the wholesale and retail level, which in turn has...
This study reviews patterns of consumption and expenditure of fish at home at disaggregate level and analyzes demand for nine different fish species/species group. The analysis is based on the household consumption survey in inland provinces of Thailand conducted during 1998-1999. Result shows that the annual per capita fish consumption...
Marine ecosystems are generally more extensive and complex than terrestrial ecosystems. Our understanding of the ecological relationships and biological processes within marine ecosystems is rudimentary but improving. In addition, our appreciation of the range of goods and services available from the marine environment and demand for competing economic uses of...
New Zealand’s fisheries legislation generally sets out a centralised and prescriptive management framework, predominantly based on annual decisions on both management measures and service delivery. A recent amendment provides for the Minister of Fisheries to approve fisheries plans, but does not specify what needs to be included in a plan...
Management of the Danish protein fisheries in the North Sea has during recent years become increasingly politicised, as various stakeholder groups are seeking influence on the decision-making process. In relation to management of the sand eel and Norway pout fisheries, two different issues are debated. In the sand eel fishery,...
The fish markets in Finland were formerly protected from international competition. The markets were gradually
opened to free competition in the 1990s due to the EEA agreement and EU membership. As a consequence, the importation of fresh salmon from Norway rapidly increased, and imported salmon captured the markets from domestic...
In many estuarine and ocean areas, aquaculture is seen as an alternative to traditional commercial fish harvesting practices. A significant problem hindering the emergence or the continuing growth of aquaculture in many areas is the conflict that arises among it and other competing ocean uses. Real world examples include the...
Rights-based management in federally managed fisheries off Alaska has evolved rapidly over the past decade. While license limited entry and individual quotas (with rights assignments to vessel owners) were the principle tools under consideration in the early 1990s, in 2002 a wider range of programs and program options are under...
There is an increasing realisation among fisheries managers that fisheries management must include participatory approaches, because fisheries management need to address complex issues including many interests, disciplines and issues. It is also becoming generally accepted that fisheries management cannot be based on simple predictability of nature and fisheries behaviour, but...
The Irish Sea, being an area fairly discrete and partially isolated from adjoining fishing grounds, lends itself well to research studies. The area is fished by Ireland and the United Kingdom, with limited effort by France and Belgium, and has been known to be overfished for quite a long time....
Despite current advances in aquaculture practices, microbial diseases are still being increasingly incriminated as a significant constraint to regulate sustainable aquaculture production, trade and economic development of this sector. A systematic research to identify various infections which induce morbidity and mortality among trout and carps was undertaken in Himachal Pradesh,...
In British Columbia “co-management agreements” are improving the sustainable management of many commercial fisheries. While some fisheries have fairly extensive co-management agreements which outline cost recovery, joint and separate roles and responsibilities for enforcement, science, and management, most do not. There are a number of important factors which have limited...
A dynamic game model is used to predict the strategic behavior of harvesters engaged in a non-cooperative fishery on a common property resource. The model predicts that an increase in the current number of harvesters in a common property fishery will reduce both the equilibrium harvest level and the current...
The main objectives of this paper are, in the first place, to review the international efforts carried out during the last ten years for fighting against illegal, unreported and unregulated fishing. In this field, the keystone is the 1982 United Nations Law of the Sea Convention. But since the adoption...
Fisheries affect fish stocks through their exploitation rate and exploitation pattern. Both influence the economic yield from the fish stock. In regulated fisheries, the exploitation rate is determined either by the acceptable level of fishing effort or catch, whereas the exploitation pattern is determined by selectivity of gears and/or regulatory...
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...
New Zealand’s quota management system, the QMS, has for years been considered as one of the most successful rights-based fisheries management system in the world. Although the hard evidence is at best patchy, New Zealand’s fishing industry is performing well ahead of most competitors, both in economic, biological and administrative...
After joining the WTO, easier access to Taiwanese market due to tariff reductions and deregulation of import restriction is expected to have substantial impacts on the fishery sector in Taiwan. Comparing to the tariff rates in 2001, the average tariff rates of fishery products will decrease 35.5%, in 2004. Especially,...
Loligo gahi (Patagonian longfin squid) has been the target of a major trawl fishery in the waters around the Falkland Islands since the early 1980s. The catch of this short-lived species can fluctuate markedly due to variation in seasonal recruitment. Ex-vessel prices of loligo are also variable due to international...
The extent to which demand and supply shocks are transmitted in the value chain is an important topic. As many value chains cross international borders exchange rate pass through is an important element in this context. In this paper a multivariate system that allow us to test different hypothesis with...
Management of individual species in a multi-species fishery poses a number of challenges for fishery management systems, including the problem of managing fish bycatch. Fish bycatch is sometimes identified as a particular problem associated with management systems based on individual transferable quotas (ITQs) but this has not always proven to...
The objective of this paper is to present a parsimonious forecasting model for the fishmeal price. The focus is on the soybean meal market’s impact on the fish meal price through the soybean meal futures price together with the stocks-to-use as an indicator of demand and supply conditions. A salient...
Although the 1982 UNCLOS endeavoured to establish EEZs and assist coastal states in being able to manage the resources throughout their range to some extent, it became obvious that further agreements were necessary to expand upon states’ international obligations in relation to conservation and management of living resources on the...
This paper is a study of the production technology and relative efficiency of vessels harvesting tiger prawns in the northern prawn fishery (NPF), one of Australia’s largest and most lucrative fishing areas. It is based on a unbalanced panel data set of 228 observations among thirty-seven vessels for the years...
Until recently the execution of the fisheries management schemes in the Netherlands was to a large extend centralized. In 1993, however, part of the executionary responsibilities was delegated to the fishing industry. In this new system, responsibilities in the management of individual transferable quota (ITQs) has been devolved to groups...
In this paper an extended version of the well-known Faustmann model is developed for solving the rotation problem in fish farming. Two particularly important aspects of the problem are emphasized: namely first, the possibilities for cycles in relative price relationships and second, the problem with limitations in release time for...
Recent increases in the volume of canning grade tuna caught in the Western and Central Pacific Ocean (WCPO) has led to concern about the increasing catching capacity of the fleet of purse seine vessels operating in the fishery. In this paper Data Envelopment Analysis (DEA) is used to examine the...
This paper explores the issue of using marine reserves in combination with quotas as fisheries management tools. The underlying biological dynamics are described by a patchy environment model, in which a metapopulation is built up by linked sub-populations that are distributed across a set of spatially discrete habitats or patches....
Globalization may affect companies in the fish-processing industry in many ways. For some, globalization poses new threats, for others it represents new opportunities. Some companies see their benefit of being located close to the resources vanish, as resources are brought out of the region, processed in low-wage countries, and distributed...
Current fisheries management approaches based on centralised government intervention have proven inadequate to deal with the present management and cannot meet its objectives including reverting stock depletion, resolving user group conflicts, increase profitability and prevent social disruption. There is no easy solution to this problem. New institutions enabling fishing communities...
Main research question: How is seafood consumption influenced by overweight and health beliefs in a region of traditional high-level fish consumption? Materials and methods: A randomly drawn sample of women aged 45-69 years who live in Northern Norway answered a self-administrated questionnaire about eating habits, socioeconomic factors and questions related...
Atlantic salmon aquaculture is a growing industry in the Bay of Fundy on Canada’s Atlantic coast. The vast majority of aquaculture sites are concentrated in a relatively small coastal region of the province of New Brunswick (NB) where the industry is viewed as a major component of regional economic development....
In 1998, the National Marine Fisheries Service (NMFS) launched a series of marine recreational angler expenditure survey in the Northeast (NE) management region (Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, and Virginia). This series was extended to the Southeast (SE) management region (North Carolina,...
The French Norway lobster (Nephrops norvegicus) fishery situated in the Biscay Bay is composed by about 250 costal trawlers. These boats are registered in harbours located in South Brittany (Le Guilvinec, Lorient, Concarneau) and in the Vendée (Sables d'Olonnes, La Cotinière). The main particularity of the fishery is that lobsters...
