Abstract

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 x 10(3) per female for wild broodstock while it was 115.6 +/- 53.6 x 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 +/- 22.7% and 54.8 +/- 26.5% for hatchery-reared broodstock, respectively. The reproductive parameters of wild and hatchery-reared flounder in the Black Sea were similar.
