Özet

Spawning period, total fecundity, egg size, and fertilization and hatching rates of wild and hatchery-reared Black Sea salmon (Salmo trutta labrax Pallas, 1811) were investigated. Wild brood-stock consisted of 15 females (4-5 years old) with a mean weight of 1773.2 +/- 1014.4 g. Hatchery-reared broodstock consisted of 28 females (3 years old) with a mean weight of 869.5 +/- 319.6 g. The spawning period lasted from mid-November to the beginning of January. Mean total fecundity was 3524.6 +/- 2106.9 and 1931.3 +/- 915 eggs/female for wild and hatchery-reared broodstock, respectively, and mean egg diameters were 5.2 +/- 0.20 and 5.0 +/- 0.24 mm. Fertilization and hatching rates were 98.4 +/- 1.71% and 88.1 +/- 8.78% for wild broodstock and 97.9 +/- 1.84% and 83.1 +/- 15.77% for hatchery-reared. The reproductive parameters of wild and hatchery-reared Black Sea salmon in northeastern Turkey were similar to those of other salmonid species.
