Creator:: McDonald, David
Abstract:: Structural time series methods are applied to modeling endogenous fishing effort in the German North Sea shrimp fishery. The effects on fishing effort of shrimp price, catch per unit effort and environmental variation are examined. Preliminary results suggest that fishing firms do not respond much to price changes but they...

Abstract:: 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...

Creator:: Gasca-Leyva, Eucario, Hernandez, Juan M., and Veliov, Vladimir M.
Abstract:: The optimal harvesting time in a fish farm is analyzed in the paper. Fish population is assumed to be heterogeneous with respect to weight, so a distributed parameter dynamic model is considered. Theoretical and numerical results are obtained and compared with the ones concerning homogeneous fish cultures only. The results...

Abstract:: When dealing with time, a fishery manager faces a major difficulty. On an N-period time horizon, should he follow several short-run objectives for every n sub-period, or should he consider only the long-run objective? If a European manager trying to implement a stock recovery plan prefers to achieve the long-run...

Abstract:: A higher dependence on the resources motivates to community participation on resources management. Uses of common property resources are not benefit to each and every person in equal rate of resources since magnitude of the resources extraction depend on the number of criterion. Selecting of the interest group for the...

Abstract:: ICES – the International Council for the Exploration of the Sea – was founded more than a century ago out of concern for overfishing. However, today’s global marine ecosystems are for the most part in a degraded state, many alarmingly so. Why is the science used so little to make...
