The impacts of fishery management actions on shore-based fishing and fishing related infrastructure have received increased attention in the Northeast region of the United States. However, analyses of these impacts have generally focused on directly affected fisheries, ignoring changes in other fisheries and on other sea and land-based activities. Developing...
Fisheries management has been carried out on the assumption that a fish population is in equilibrium with the fishing effort under the average environmental conditions and hence there must be a maximum sustainable yield (MSY). However, since the simultaneous rise and fall of the interdecadal and global scale of sardine...
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,...
From 1991 to 2003, number of fishing boats increased from 43,940 to 83,122. The average power per boat increased from 18HP/boat to 49.3HP/boat. Fishing productivity seems to be gradually decreased from 0.89ton/HP to 0.35ton/HP. In this period, the yield of marine fisheries has been constantly increased with an annual average...
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....
Seven economic instruments including property right regime, tradable permit, bond and deposit refund, liability, fiscal instrument, financial instrument, and charge system were considered for rehabilitations of coastal resources including mangrove, coastal water, coral, sea grass and seaweed, tourism, and fishery resources. Criteria on selective economic instruments were previous practice, management...
Western Australia operates a diverse enforcement and education program aimed at achieving high compliance in a wide range of commercial and recreational fisheries managed using a mix of input and output controls. Since enforcement resources are invariably insufficient to totally eliminate non-compliance with fishery rules, it is important to ensure...
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,...
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...
This paper develops an option value model to examine vessel owners in deciding to participate or not in the vessel buyback program. The model accounts for the uncertainty generally involved in a decision to retire an aged vessel and the underlying value of waiting for new information about the profitability...
