In this study, the age-dependent reproductive performance of 4 th generation of hatchery-origin Black Sea trout (Salmo labrax Pallas, 1814) females was determined with the aim of understanding breeding characteristics of ideal broodstock management plan for Black Sea trout.The 2 + , 3 + , 4 + and 5 + years old females (n=131, 104, 63 and 28, respectively) with weights ranging from 919.45±36.22g to 2439.21±139.28gwere used.Reproductive rates of females (2 + , 3 + , 4 + and 5 + years old) were determined as 22.14%, 60.30% and 17.56% for 2 + , 17.47%, 72.82% and 9.71% for 3 + , and 19.05%, 68.25%, and 12.70% for 4 + years old in November, December and January, respectively.Fertilization rates were obtained 94.31%, 95.02%, 96.03% and 93.39%, respectively.The total fecundity was positively correlated with the age and weight (r=0.84)but negatively with the relative fecundity (r=-0.24).The difference between 2 + and 3 + age groups' total fecundities was insignificant, and the 4 + and 5 + age groups were different from all groups.In addition, there was no significant difference in fertilization rates among all age groups' rates but the 5 + age group had slightly lower value (P<0.05).For ideal broodstock management in Black Sea trout production, based on the results of this study, it is recommended to use 3 + and 4 + years old females with high breeding efficiency and remove 5 + years and older females from the broodstock.with the first sexual maturity length of 44.76 cm in their natural environment in eastern parts of the Black Sea, they started to spawn in November and continued until mid-December.Bio-ecological and cultivation characteristics of Black Sea trout has been studied by Central Fisheries Research Institute (CFRI) researchers since 1998.According to these studies; Black Sea trout eggs were hatch approximately in 38-40 days at 10°C in fresh water (Firidin, Cakmak, & Aksungur, 2012).Subsequent to hatching, larvae consume their yolk sac and constitute pedestal digestive structures within 30 days (Cankiriligil, Cakmak, & Ozcan Akpinar, 2016).
