There is great concern at present that fish stocks are being depleted by over-fishing. Part of the problem of over-fishing is caused by the common property nature of the fishery resources. In particular, high seas fishery resources, such as highly migratory fish stocks (HMFS) and straddling fish stocks, suffer from...
Plankton feeding fish populations on high latitudes have a strong seasonal growth as food only is available when the sun is above the horizon. The rest of the year the biomass will be reduced as a result of natural mortality and reduced weight on each individual. Prices and costs per...
This paper begins by outlining the history of the Rules of Origin negotiations in the World Trade Organization (WTO), unfinished business from the Uruguay Round that is separate from the current Doha Round. The treatment of products of the sea is one of a large number of unresolved issues; progress...
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...
The objective of the European POORFISH project (2005-2008) is to create an advisory system (assessment, advice, and/or management) approach based on methods able to deal with data poor systems (utilizing both expert knowledge and published information in addition to existing data sets). There are basically at least three types of...
Whilst the study of resource extraction under uncertainty has a long history in resource economics, there has been less attention paid to endogenous efforts to reduce uncertainty through learning and information acquisition. An unresolved empirical question is the degree to which individual extractors learn from the behavior of other extractors....
Nearly 75% of the stocks in the waters of the European Union are overused. Therefore, recovery programs
are both necessary and urgent. However, the decisions made by the fisheries ministers rather seem
to prolong the overuse situation instead of putting an end to it.
From an overall perspective, it would...
Two successful cases of sea urchin enhancement activities were considered using the experiences of two neighboring provinces in Ilocos Sur and Ilocos Norte, both located in Northwestern Luzon, Philippines. One case was done at the coastal waters of Nagabungan Bay in Pasuquin, Ilocos Norte, which experienced a decline in sea...
Since MSC certification of the Gulf of Alaska and Bering Sea pollock fisheries in the U.S., anecdotal evidence suggests that products from these fisheries have benefited in the marketplace relative to products
from the Russian pollock fishery. In particular, a testable hypothesis is that certified U.S. pollock has achieved a...
The red king crab (Paralithodes camtschaticus) is an alien invasive species in the Barents Sea representing a value as well as a potential pest. A bio-economic model is applied analysing the costs that traditional fisheries incur as a result of the king crab invasion, as well as the income from...
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...
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...
This paper analyses the management strategy that was adopted by a local fishers organisation in order to promote a restocking/sea-ranching program concerning a small-scale shellfish fishery, the scallop fishery of the bay of Brest (France). Two main topics are addressed: space management and access regulation, in a context dominated by...
The Working Group on Fisheries Systems of the International Council for the Exploration of the Sea (ICES) has identified the production and the use of knowledge in policy and management decision-making as one of the critical processes to be analyzed in the evaluation of the performance of fisheries systems. Many...
Like many global pelagic fisheries, the Hawaii-based longline fishery continues to face increased pressure to reduce the incidental catch of endangered sea turtles and/or other sensitive species. Aggregation and
movement of both sea turtles and fish are directly associated with climatic variations and oceanographic conditions. As a result, both targeted...
The cod stock in the North Sea is threatened by overexploitation. To recover this fishing stock, pressure needs to be reduced. This implies that catch compositions with small amounts of cod are preferred by public policy makers. The present analysis assesses the technological efficiency of fishing trips, considering landings of...
At a hearing about the Green Paper (an analysis of the EU fisheries policy over the last 10 years and an outlook for the next decade) the following statement was given by an economist: „The Ecosystem Approach is the fata morgana of the fisheries biologists.“ Indeed, a lot of biologists...
This study was commissioned by OWET to determine the possible economic benefits to Oregon and Oregon’s coastal communities from having a thriving wave energy industry. While wave energy industry growth will proceed along a continuous path, this study examines the economic impacts at three distinct stages: Research and Development Stage;...

The Norwegian government has recently put forward a white paper concerning the management of the red king crab in the Barents Sea. The crab is an introduced species in the Barents Sea. The motive of the introduction was to improve the economy of the Russian coastal fisheries, as the crab...
Fishing activities within the Galapagos Marine Reserve (GMR) are restricted to small-scale levels by national law. The fishing sector has relied on just two fisheries, sea cucumber and spiny lobster, and a
strong Asian export market. Despite a series of input and output controls and a co-management scheme, stocks have...
