Abstract
This study presents a bioeconomic model of prey-predator interactions incorporating the presence of refuges for prey species to mitigate predation. The main objective is to assess the impact of prey refuges on prey biomass, predator biomass, catches, fishing effort, and profits for fishermen exploiting these marine species. The model analyzes system positivity and boundedness, examines equilibrium points and their stability, and conducts numerical simulations by varying the refuge availability parameter (m) to interpret the effects on fishing effort, catches, and profits across different scenarios. The findings shed light on the dynamics of the ecosystem and highlight the importance of refuge availability in sustainable fisheries management, supporting the conservation of marine resources and the well-being of fishermen.
期刊介绍：
The Journal of Coastal Conservation is a scientific journal for the dissemination of both theoretical and applied research on integrated and sustainable management of the terrestrial, coastal and marine environmental interface.
A thorough understanding of both the physical and the human sciences is important to the study of the spatial patterns and processes observed in terrestrial, coastal and marine systems set in the context of past, present and future social and economic developments. This includes multidisciplinary and integrated knowledge and understanding of: physical geography, coastal geomorphology, sediment dynamics, hydrodynamics, soil science, hydrology, plant and animal ecology, vegetation science, biogeography, landscape ecology, recreation and tourism studies, urban and human ecology, coastal engineering and spatial planning, coastal zone management, and marine resource management.
