The n-3 fatty acids have important
effects to modulate and prevent human diseases, particularly
coronary heart disease. Their effects upon the brain later in
life to prevent certain disorders such as Alzheimer's Disease
are unknown but are certainly worthy of study. Certainly the
evidence is now very strong that the...
Natural resource management is a challenging undertaking in the best of circumstances. However, managing living marine resources is frequently confounded by the vast, alien, and oft-times hostile physical environment within which the organisms reside. The subtleties and complexity of the marine life-web, which in important respects have come to include...
Dungeness crab stocks are healthy, with naturally occurring fluctuations in abundance. The fishing method is targeted and gear is selective. Bycatch mortality is minimal to non-existent. The issues facing this industry are not biological, but socioeconomic. The industry is working with the state management system to ensure a sound future...
Detailed economic analyses of fisher performance are critical inputs in improving the management of fisheries. The paper provides guidelines about the economic methodologies and the data required to monitor and assess the performance of individual transferable quota fisheries. In particular, it describes the methods of evaluation that could be applied...
This historical survey sweeps across a thousand years, divided into five very unequal stages. Over most of the stages property in tide-water fisheries was lost. Fishers lost control of the fishstock and of the markets they served. Governments responded with fishing regulations, which have served as a basis for regaining...
The Conference Program for IIFET, held July 10-14 in Corvallis, Oregon. Program lists the sessions by date and time and includes the session titles, speakers and paper titles.
The method of constructing scenarios is neither straightforward nor unproblematic. We propose first of all the term epistemic closure for representing the necessary methodological limitations of scenario construction. Whenever a particular kind of epistemic closure becomes a habit within some field of scenario-making, we use the term conventional scenarios. The...

A recent analysis of the potential for management cost recovery in the UK suggested that such a policy would be detrimental to UK fishers if other European countries did not implement a similar charging policy. Most of the waters exploited by UK fishers are also exploited by fishers from other...
Recently, Mediterranean lagoon environment, mainly in the North Adriatic area, has been threatened by the overexploitation of fishery. Fishing has been rapidly growing since clam (Tapes phippinarum) fishery has spread over several lagoons. Fishing growth has been accomplished by capital-intensive fishery equipments increasing harvesting beyond the sustainable biological growth. This...
A linear programming (LP) profit-maximization model and a Target MOTAD risk programming model were developed to identify optimal management strategies and associated risk levels for the aquaculture of penaeid shrimp in Honduras. Data for this study were provided by three cooperating shrimp farms and included complete production records of 1,004...
