Contribution of Studying the Assessment of Fish Stocks Using Length Structured Model


Abstract in English

Most of the fish stocks in the world are threatened by overfishing and/or degraded environmental conditions, stock assessment of marine resources is therefore worldwide recognized as a major matter. This study aims at highlighting the analytical models used in the stocks assessment, which depend on the cohort analysis using information on the length based method which used when only length composition data for fishery.
