Effect Of Water Temperature On Growth Of Hatchery Reared Black Sea Turbot, Scophthalmus Maximus (Linnaeus, 1758), Temel Şahi̇n
Effect Of Water Temperature On Growth Of Hatchery Reared Black Sea Turbot, Scophthalmus Maximus (Linnaeus, 1758), Temel Şahi̇n
Turkish Journal of Zoology
A rearing experiment was carried out to examine the effect of water temperature on the growth of the Black Sea turbot, Scophthalmus maximus, at ambient temperature (mean 15.2±0.6°C), 18, 20, 22 and 24°C with fish of 34.4±9.9 g initial body weight. The experiment lasted 30 days and the fish were fed to satiation three times a day with a commercial pelleted diet. Survival rates starting with the control group were 100, 83.4, 68.4, 3.4, and 1.7%, respectively. Although the mean weights of the groups were very similar at the beginning of the experiment, they had become markedly varied by the …
Larval Rearing Of The Black Sea Turbot, Scophthalmus Maximus (Linnaeus, 1758), Under Laboratory Conditions, Temel Şahi̇n
Larval Rearing Of The Black Sea Turbot, Scophthalmus Maximus (Linnaeus, 1758), Under Laboratory Conditions, Temel Şahi̇n
Turkish Journal of Zoology
To establish a seed production technique for Black Sea turbot, Scophthalmus maximus, eggs and larvae were observed under artificial rearing conditions. Larvae were obtained artificially from eggs of tank-held broodstock. The egg fertilization was 27.6% and the fertilized eggs were 1.213±0.063 mm in diameter, were spherical pelagic and had one oil globule. From an initial length of 3.12±0.14 mm on day 0, the larvae grown to 167.28±15.32 mm in the normal group and to 159.98±12.25 mm in the abnormal group on day 246. The feeding regime consisted of Nannochloropsis oculata, Brachionus plicatilis, Artemia, and granule feed. The survival rates were …
