Harvest Strategies for an Ecosystem Approach to Fisheries Management in Western Mediterranean Demersal Fisheries
The serious overfishing of most Mediterranean stocks demands urgent reforms of the management measures aiming to guarantee the sustainability of resources, notably when compared with the improvement observed in other European areas. The new EU Common Fisheries Policy (CFP) constitutes an excellent opportunity to introduce the changes needed for such a reform. According to this CFP, all European...

متن کاملHarvesting fisheries management strategies with modified effort function
In traditional harvesting model a fishing effort E is defined by the fishing intensity and does not address the inverse effect of fish abundance on the fishing effort. In this paper, based on a canonical differential equation model, we developed a new fishing effort model which relies on the density effect of fish population. This study concludes that a control parameter β( the magnitude of the...
متن کاملEvolutionary models for, fisheries management
The potential use of functional evolutionary models and mechanistic ecological models as predictive tools in fisheries ecology is discussed. Evolution by natural selection is a force that leads to ecological adaptations of the individuals in the populations. By mechanistic modelling of the sense organs, we may model how individuals perceive their environment, and by life history theory we may p...
متن کاملToward Darwinian fisheries management
There is increasing evidence that fishing may cause rapid contemporary evolution in freshwater and marine fish populations. This has led to growing concern about the possible consequences such evolutionary change might have for aquatic ecosystems and the utility of those ecosystems to society. This special issue contains contributions from a symposium on fisheries-induced evolution held at the ...
