Abstract:: The vaquita, a critically endangered marine mammal, is a bycatch to shrimp strawl and gillnet fisheries in the upper Gulf of California. Reducing vaquita bycatch, however, is complex. The fisheries are smaller-scale and major contributors of income and employment to coastal communities. Although tourism is increasingly important, fishing remains an...

Abstract:: 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...

Abstract:: The optimal management of the European hake fishery (southern stock) is analysed. Since the activity of the fleets has different impacts on marine resource in this fishery, depending on the selectivity of their gears, the degree of selectivity is included in the analysis. Likewise the changes in the selectivity of...

Abstract:: Les graves atteintes aux équilibres des écosystèmes côtiers et littoraux sont devenues une préoccupation partagée par les chercheurs et les développeurs. La détérioration du bien-être des populations gui en sont soit la cause, soit la conséquence, impose la révision du discours économique prédominant dans les programmes de développement.

Abstract:: As early as 1491 in an Act of Parliament during the reign of Henry VII of England, overfishing and the capture of juveniles were recognized as root causes of declining fish catches, and since then, minimum capture sizes, closed seasons and areas, and gear restrictions have been implemented to address...

Abstract:: Under the provisions of the United Nations Convention for the Law of the Sea (UNCLOS), coastal states must provide for access to harvest the living resources within their EEZs. Where the state does not have the capacity to harvest the entire sustainable catch, it must grant other states access to...

Creator:: Mikkelsen, Eirik
Abstract:: Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish population-dynamics and production, coupled with an aquaculture production model, to investigate effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....

Abstract:: Fisheries resource is a great natural asset to this planet and ensuring the responsible use of these resources can enrich the lives of its people. However, global fishery resources are under high and mounting pressure which is severe, particularly in the developing countries. Until recently, traditional fisheries management has failed...

Abstract:: Atlantic Sea scallops have historically supported the second most valuable fishery in the northeastern United States. Intense fishing pressure during the early 1990s led to drastic decreases in population biomass and commercial landings. Total harvest, which exceeded 17,000 metric tons (MT) in 1990, declined to around 7,300 MT in 1993....

Abstract:: There has been a structural shift in the global supply, demand and trade in fish and fisheries products since the early 1980s that has shattered the traditional dominance of the developed nations. Despite a declining trend in the global exports of primary products, the percentage contribution of fish has been...
