abstract={This study aims to evaluate the food ecology of <i>Trichiurus</i><i> </i><i>lepturus</i>. 876 specimens of <i>Trichiurus</i><i> </i><i>lepturus</i> were collected monthly from January 2018 to December 2018 in Abidjan fishing port and their stomachs contents examined. The number of stomachs non-empty examined in this study is 176 stomachs out of the 876 obtained. The index of preponderance (%PI) showed that <i>T.</i><i> </i><i>lepturus</i> had a carnivorous diet piscivorous tendency. Twelve items grouped into three categories, Fishes (PI = 97.99%), Crustaceans (PI = 2.10%) and Molluscs (PI = 0.002%) were the major feed. Juveniles (Total Length (TL) &lt; the length at first maturity (L<SUB>50</SUB>= 48.02 cm)¡­) consumed crustaceans (PI = 59.18%) as main preys and fishes (PI = 40.18%) as secondary preys. In adults (Total Length (TL) > the length at first maturity (L<SUB>50</SUB>= 48.02 cm) ¡­), Fishes (PI = 97.59%) were the main preys eaten. According seasons, <i>T.</i><i> </i><i>lepturus</i> feeds Fishes (PI = 89.02 %) and Crustaceans (PI = 10.98%) during miner warm season and mayor cold season Fishes (PI = 94.26%) and Crustaceans (PI= 5.65%). They only feed on Fishes (PI = 99.91%) during the miner cold season (mcs) and mayor warm season (PI= 99.1%) (MWS). Bray-Curtis similarity showed no significant difference (p ? 0.05) between diet of juveniles and adults of <i>Trichiurus</i><i> </i><i>lepturus</i> in all seasons.},
