Abstract :A total of 32 the European flat oyster insert ignore into journalissuearticles values(Ostrea edulis Linnaeus, 1758); on the rocky shores of 0-5 m depths in Ordu province in the southern Black Sea were carried out in order to evaluate morphometric aspects and growth parameters. The shell length insert ignore into journalissuearticles values(SL);, shell width insert ignore into journalissuearticles values(SWi);, shell thickness insert ignore into journalissuearticles values(ST); and shell weight insert ignore into journalissuearticles values(SW);, total weight insert ignore into journalissuearticles values(W); and meat weight insert ignore into journalissuearticles values(MW); were measured in this study. The mean SL of the collected individuals was measured as 69.49 ± 27.10 mm insert ignore into journalissuearticles values(min: 22.4, max: 145.8);. Moreover, the average body weight was estimated to be 66.19 ± 60.78 g insert ignore into journalissuearticles values(1.5–241.7);. The calculated “b” value of O.edulis is less than 3 and the growth was negative allometric. This study presents the first morphometric properties of European flat oyster in the southern Black Sea. In addition, this is the first study conducted for O. edulis in the Black Sea and the maximum sizes given for the Mediterranean, Aegean and Black Sea.
