Fishermen contribute to protection of marine reserves

How to model marine reserves ?

The safeguarding of resources is one of the principal subjects of halieutics studies. Among the solutions proposed to avert the disappearance of species, the setting in place of no take reserves is often mentioned. Most work on this subject, theoretical as well as applied, was undertaken in recent years. In this paper, we seek to compare two different models presented in existing literature by ...

The Economics of Marine Reserves

Marine reserves can be a useful supplement to other methods of fisheries management, but marine reserves alone are not likely to achieve a great deal in economic terms and perhaps not even in terms of conservation. The effects of marine reserves with open access elsewhere are analyzed, using a logistic model for a population with a patchy distribution. It is assumed that a marine reserve is est...

Marine reserves with ecological uncertainty.

To help manage the fluctuations inherent in fish populations scientists have argued for both an ecosystem approach to management and the greater use of marine reserves. Support for reserves includes empirical evidence that they can raise the spawning biomass and mean size of exploited populations, increase the abundance of species and, relative to reference sites, raise population density, biom...

Reply to Hilborn: Role of marine reserves depends on assumptions.

We appreciate the points made by Hilborn (1) that changing the assumptions we made could lead to different conclusions. In fact, our overall goal in developing the model in ref. 2 was similar to the goal in developing the model in ref. 3 to indicate how a model with clear assumptions would shed light on the role played by marine protected areas in spatial fishery management. Here we make three ...
