Abstract

Knowing the diet composition of a fish species provides a key to understanding their place in the marine food web. Between May 2021 and September 2022, 120 stomachs of horse mackerel with sizes between 8.0 and 15.5 cm (average length 11.43±1.35 cm), were sampled and analyzed. The identified prey were: fish (Engraulis encrasicolus - anchovy), copepods (Acartia clausi, Calanus euxinus), molluscs and annelids polychaetes. Regarding the value of the Relative Importance Index (RII), the copepod group dominated. This prey is probably characteristic of small size individuals that dominated the samples. Their diet was similar between years. The analysis of Fullness Index (FI) highlights an increase in the index according to length. There are no significant FI differences between the stations, month and years.
