Fish Population Dynamic and Stock Assessment (2+1)

2.2.1. Introduction

Data on age specific mortality and fertility are organized in a life table. The life table has an important role in fish population.

The structure of a population is specific of a species or subspecies and the environment. The population structure of a species or groups within species has certain stability. Once the environmental condition changes, the population of a species changes continuously, hence the structural resemblances and other features of the species show changes.
