Abstract

This study considered a non-linear mathematical model of skilling fishery management to understand the dynamics of lives in an aquatic system which involves two zones of unrestricted and restricted fishing zones. The model analysis showcased the existence of equilibrium points in line with the biological and bionomic, dynamical behaviour of equilibrium points and also derived the conditions for stability and instability of the system. The behaviour of this dynamical model of fishery management were illustrated using numerical simulations to establish the analytical results. The findings of this study showed that inadequate knowledge of the resource and ecosystem, lack of interaction between the government and stakeholders, inaccessibility of financial resources to meet specific needs, weak implementation of agricultural policies and programmes, inadequate practical advisory/extension services and lack of monitoring and evaluation of programme/project team led the system to be unstable which implies that the eigen values were greater than zero. This paper identified that management of fisheries is affected by climate change, human actions and population, shortage of food, poverty and lack of policy executions. Amongst all, the study suggested that there should be introduction of environmental impact assessment for fisheries policies to be implemented, skilled or trained fisheries administrators that will monitor and evaluate the policy/programme consistency, against specified goals need to be given more financial resources, and properly staffed and equipped to address effectively all aspects of sustainable fisheries development and management. should be adopted and their efficacy monitored and evaluated against specified goals. There should be better protection to environmental hazards, control of waste disposal and pollution. Finally, government at all levels should recognize its benefit and work towards integrating skilling fisheries management activities, including sharing of expertise and resources for education, research, technology, monitoring, control and surveillance activities and development of the relevant legislative framework.
