Aquaculture is increasingly important for the future supply of fish because of steadily increasing demand while supply from fisheries is stagnating. In the EU aquaculture production has grown strongly in some countries, such as Spain and Greece, but was flat at a low level in others, such as in Germany,...
When weak and strong fish stocks are caught in the same fishery, managing for the protection of the weak
stock may result in foregone economic benefits from harvest of the strong stock, while managing for the
strong stock may result in overfishing of the weak stock. A particular complication arises...
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...
Real options models arguably provide a useful framework for understanding individual fishermen's investment decisions, which play an important role in fisheries management issues ranging from capacity reduction to stock assessment. While these models appear to predict actual behavior reasonably well, one important difficulty in applying them is that the salvage...
Economic performance of different fleet segments varies considerably from year to year, with some segments experiencing increased profitability while others experience decreased profitability. This variation is generally considered to be a consequence of the stochasticity in the industry. However, there is growing evidence that fisheries may not be as stochastic...
Chronic overcapacity has been identified as a major cause of the overfishing of Europe’s fish stocks and
the poor economic performance of the European fishing fleets. Mechanisms are needed to ensure that the
capacity of European fishing fleets remain proportionate to available fish stocks. To that end, the
European Commission...
An important subset of natural resource management addresses preserving and/or harvesting biological resources. Examples are policies that derive from the Endangered Species Act including habitat conservation plans, the U.S. Forest Service’s logging practices, and fishery management councils’ decisions regarding catches. To understand the effectiveness of management policies requires an understanding...
Economists and biologists have recognized that spatial and temporal area-closures may provide an effective means of managing the impact that fisheries have on one another and upon threatened species. To date, however, little work has been done to estimate the economic impact of protected areas on commercial fishing. One significant...
Though long a standard technique in engineering and medical research, duration or survival analysis has
become common in economics only in recent decades, and in fisheries economics we are aware of only
one previous study. In this paper, we demonstrate the usefulness of duration analysis to understanding
fleet dynamics, specifically...
