We report the first record of Hermaphroditism in Bullet tuna Auxis rochei caught in Syria – Eastern Mediterranean Sea When doing our current research entitled: "A Biological Study of economic marine fish species Auxis rochei in the marine waters of Lattakia and determining the concentrations of heavy elements in their tissue". The Bullet tuna Auxis rochei was sampled in purse seine from Ras Albasit – Eastern in Mediterranean Sea, between October 2021 - September 2022, we found a low prevalence of Hermaphroditism (one sample out of a total of 98 A. rochei) during studying the gonads and stages of sexual maturity for those individuals.
