 Abstract

This study aims to determine the seasonal feeding variation for Mugil cephalus caught from the estuary of the Senegal River. Random sampling using the creel survey on site was carried out in three fish catch landings (Goxumbathie, Gueth Ndar Diagne and Sor) of the Senegal River estuary. The results obtained from the analysis of stomach contents showed no significant difference in seasonal variation in the diet of yellow mule among age classes (0 +, I + II + III + IV + and V +). For 1478 examined stomachs, coefficients of emptiness were 7.62, 6.69 and 5.87%, respectively for the cold dry, hot dry and rainy seasons. Factorial Analysis of Correspondences (FCA) performed on the data of different prey ingested depicted that yellow mullet feed primarily on pinnate diatoms, cyanobacteria, detritus and centric diatoms with respective occurrence indices of 26.48, 24.27, 8.00 and 7.71%. Other occasional feeds such as sand and zooplankton are considered as secondary foods.
