Navigating the Allee effect: unraveling the influence on marine ecosystems

Abstract

In this study, we delve into the complex interplay between the Allee effect and a tri-trophic marine ecosystem of zooplankton, sardines, and sharks in Moroccan waters, aiming to contribute to the field of coastal conservation, planning, and management. Our investigation focuses on understanding the impact of the Allee effect on catches, profits, and fishing efforts within the context of bioeconomic models. By analyzing the positive aspects, boundaries, and equilibrium points, we examine how the Allee effect influences the fishing efforts and overall performance of fishermen, providing valuable insights for sustainable fishing practices. The research outcomes shed light on the intricate interplay among the Allee effect, economic variables, and the abundance of diverse species, thereby offering crucial guidance for effective coastal conservation, planning, and management strategies.
