Reproductive performance of turbot (Psetta maxima) in the southeastern black sea

Abstract

Spawning time, total fecundity, fertilization, and hatching rates of turbot (Psetta maxima) were investigated in 10 wild female broodstock (mean wt: 3809.7 ± 1238.4 g). Spawning lasted 37 days, from April 17 to May 23. Mean total fecundity was 2329 ± 1260 × 103 eggs per female. Fertilization and hatching rates were 30.6 ± 25.4% and 17.9 ± 16.1%, respectively. A significant positive correlation was observed between body weight and total fecundity (r = 0.637, P < 0.05). The timing and frequency of hand stripping, fecundity, fertilization, and hatching rates in turbot are presented. © TÜBİTAK.
