MODEL OF A SHRIMP POPULATION (PHILOCHERAS-TRISPINOSUS) .1. SIMULATION OF THE SIZE STRUCTURE
Résumé
This study describes a stochastic model simulating the kinetics of the size structure of a shrimp population (Philocheras trispinosus). The model incorporates relationships which constitute the main functions of the population: growth, mortality and reproduction. The observed and simulated data are compared by multifactorial analysis. Two values are used for the adult mortality. The survival coefficient of the larvae is corrected to stabilise the simulated populations. The kinetics of size structures is followed with a good agreement between the simulations and the observations.
