ABSTRACT

In our current research titled "Study of the Biology of Reproduction, Trophic Spectrum, and Fish Stocks of Migratory Fish Species Sillago suezensis (Forskal, 1775) (Sillaginidae) in the Marine Waters of Lattakia", we collected 338 individuals between June 23, 2022, and June 23, 2023, using local fishing methods, particularly gill nets, at depths ranging from 3 m to 50 m. While analyzing the gonads and stages of sexual maturity of these specimens, we identified hermaphroditism in some members of the fish species Sillago suezensis. Our findings, when compared to existing data indicating that this species is typically gonochoristic, reveal the presence of hermaphrodite individuals in the Syrian marine environment for the first time. Consequently, this research documents the first global observation of hermaphroditism in S. suezensis, classifying it as an early protandrous species.
