Abstract

The knowledge on size class of yellow mule (Mugil cephalus) is essential to describe a mathematical model on the growth of the species. The objective of this study is to test the growth model of Mugil cephalus population cohort structured in length class frequency. The cohort diet is generally based on plankton at its first stage of growth in the estuary of the River Senegal. A growth software, developed under the FreeFem ++ software has allowed to describe the growth of the population of M. cephalus. The model depicted that the size is the most effective indicator to monitor the growth of yellow mules. The study aims at building a flexible mathematical model that could be used to describe other communities of fish and insects assemblages in order to better understand the growth dynamics of their populations. It is concluded that the use of less variable in the model may make it easier for utilization/application in fisheries management.
