Bioeconomic modelling for the sustainable exploitation of three key marine species in Morocco

This study aims to deepen the understanding and optimise fishing activity in Morocco by holistically integrating biological and economic aspects. We develop a biological equilibrium model in which these competing species present their natural growth by logistic equations, taking into account density and competition between them. The integration of human intervention adds a realistic dimension to our model. A company specifically targeting the three species thus influences population dynamics according to their fishing activities. The aim of this work is to determine the fishing effort that maximises fishing's profit, taking into account the constraints associated with conserving ecosystem equilibrium.
