Fish Population Dynamic and Stock Assessment

5.1.1. Introduction

The fundamental objective of any responsible fishing operation is to give maximum return to the fishermen with minimum efforts on the fish populations and the environment. Minimizing effects of fishing on the environment and fish population is much more difficult for quantification. This is because of complex interaction between the fishing process, fish and the environment. Over the years, improvements to fishing gear and fishing techniques have made fishing more effective with little consideration given to their effects on fish population and fish habitat. The effect of fishing on the population could be considerably reduced by making the gear selective.
