Title: Reproductive Performance of Wild and Hatchery-Reared Black Sea Turbot, Psetta maxima, in the Southern Black Sea Coast
Abstract: In this study, spawning period, total fecundity, fertilization and hatching rates of wild and hatchery-reared turbot, Psetta maxima, were investigated.Fish were spawned over a 3-month period, from April to June.Wild broodstock consisted of sixteen females with a mean weight of 3742±1509 g.Hatchery-reared broodstock consisted of seventeen females with a mean weight of 3604±1398 g.Mean total fecundity was 2.4±1.71x10 6and 2.3±1.75x10 6eggs per female for wild and hatchery-reared broodstock, respectively.Fertilization and hatching rates were 59.2±17.07%and 67.3±30.67%for wild and 67.1±18.87%and 61.3±30.85%for hatchery-reared broodstock.The reproductive parameters of wild and hatchery reared turbot showed no significant difference, which warrants further investigation of both in provision of a sustainable fishery.
