This paper deals with the problem of softwaresensor (state estimation) to study the continuous age structured model of a harvestedfishpopulation,in order to get an estimation of the biomass of fishes by age *** our case the fishing effort is considered as a control term,the age classes as a states and the quantity of captured fish as a measured *** continuous non-linear model is first represented by a Takagi-Sugeno ***,we develop a technique for designing a multimodelsoftwaresensor (called also observer) corresponding to this system and show its asymptotic *** design conditions are given in linear matrix inequalities (LMI) terms which can be solved efficiently using existing numerical *** simulation results demonstrate the effectiveness of the proposed method.
