Modelling the dissipative effect of fisheries

Abstract

When managing marine fish resources in the present context of world generalized exploitation of resources, in which many species are overexploited, management processes have to consider research theoretical results. In this paper, a model is proposed for fisheries in the context of chaos. It is shown how the theory of chaos and a model based on chaos may explain and model the fisheries. This model shows that fisheries may dissipate marine species in certain circumstances. The model permits to show that overfishing may cause a problem of irreversibility in several species recovering, after certain stages for the stocks.
