Stochastic Optimization in Population Dynamics: The Case of Multi-site Fisheries

Autor: Diaraf Seck, Sidy Ly

Publikováno v: Trends in Mathematics ISBN: 9783030573355

In this paper we build and study stochastic models governing fisheries activities. The evolution of population is described by stochastic differential equations derived from the proposed model. By using tools of dynamic programming we also derive som

A Bioeconomic Model of a Multi-site Fishery with Nonlinear Demand Function: Number of Sites Optimizing the Total Catch

Autor: Moussa Balde, Pierre Auger, Sidy Ly

Publikováno v: Acta Biotheoretica. 62:371-384

We present a mathematical model of a fishery on several sites with a variable price. The model takes into account the evolution during the time of the resource, fish and boat movement between the different sites, fishing effort and price that varies

A Model of a Multi-Site Fishery with Variable Price: from Over-Exploitation to Sustainable Fisheries

Autor: Fulgence Mansal, T. Nguyen-Huu, P. Auger, Moussa Balde, Sidy Ly

We present a mathematical model of a fishery on several sites with a variable price. The model takes into account the evolution during the time of the resource, fishes and boats movements between the different sites, fishing effort and price that var

We present a mathematical model of two competing marine species that are harvested. We consider three models according to different levels of complexity, without and with species refuge and density-independent and density-dependent species movement b
