Turkish Journal of Zoology
The spawning period, total fecundity, egg size, and fertilization and hatching rates of wild and hatchery-reared flounder, Platichthys flesus luscus, are investigated in this report. Wild and hatchery-reared broodstock consisted of 18 females (452.8 ± 193.2 g) and 17 females (138.9 ± 47.4 g), respectively. The spawning period lasted 79 days, from 22 January to 10 April. Mean total fecundity was 285 ± 157.9 × 10^3 per female for wild broodstock while it was 115.6 ± 53.6 × 10^3 eggs for hatchery-reared broodstock. The fertilization and hatching rates were 38.2 ± 17.0% and 62.3 ± 24.1% for wild and 45.3 …

Turkish Journal of Zoology
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 x 10^3 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.
