Abstract :In this study, the quality and reproductive success of wild Black Sea Trout insert ignore into journalissuearticles values(Salmo trutta labrax); were investigated. In total 32 wild trout insert ignore into journalissuearticles values(27.3±13.6 g and 13.9±2.3 cm); from the Bıçkı Stream in Kocaeli Province in the Marmara Region were kept in circular fiberglass outdoor flow-through tanks insert ignore into journalissuearticles values(1.5m ø); at the mean water temperature of 11.8±4.5 °C. In November 2016, when the water temperature was 8.4 °C, the first spawning of wild trout occurred. Sperm volume insert ignore into journalissuearticles values(ml);, Motility insert ignore into journalissuearticles values(%); and VCL insert ignore into journalissuearticles values(μm/sec); values were determined to be 7.5±2.5, 70.42±0.83 and 70.35±3.98, respectively. The weight insert ignore into journalissuearticles values(g);, total fecundity and egg diameter insert ignore into journalissuearticles values(mm); values of female fish were listed to be 513.75±78, 1.171±171, and 3.84±0.02, respectively. In the experiment, 5.859 wild Black sea trout eggs were fertilized. The eyed-egg stage occurred 24 days insert ignore into journalissuearticles values(288 day-degree); post fertilization and the survival rate from fertilization to the eyed-stage was 28%. Wild Black Sea trout larvae from P1 insert ignore into journalissuearticles values(Paternal Generation); hatched 48 days after fertilization with the hatching rate of 7%.
