dc.description.abstractThe aim of this study was to investigate seasonal variations of growth performance and biochemical composition, fatty and amino acids profiles of cage-cultured gilthead sea bream (Sparus aurata) in the Black Sea. The research was carried out on a yearly basis in the offshore cage systems of a commercial fish farm located on the coast of Samsun province, Turkey. Fish with an initial average weight of 2.44 +/- 0.03 g reached a harvest weight of 474.60 +/- 8.64 g with a survival rate of 94.26 +/- 0.60% in 14 months. The average specific growth rate and feed conversion rate were 0.92 +/- 0.30% and 1.45 +/- 0.05 respectively. Seasonal variation of total essential and total non-essential amino acids and EAA/NEAA ratios ranged between 7.80 +/- 0.00-11.22 +/- 0.02 g/100 g, 8.19 +/- 0.00-9.94 +/- 0.01 g/100 g and 1.01 +/- 0.00-1.18 +/- 0.01 respectively (p < 0.05). The average of total omega-3, omega-6 and omega-9 values were 11.63 +/- 0.68%, 24.29 +/- 0.84% and 28.78 +/- 0.17% respectively. It was determined that gilthead sea bream showed a remarkable growth performance over the 14 months period under offshore marine conditions in the Black Sea. Growth performance, biochemical composition, fatty and amino acids profiles in fish were influenced by seasonal changes of water temperature and nutritional value of the used diets. Findings of the present study provide remarkable information in terms of the year-round growth performance and meat quality of cage-cultured gilthead seabream based on a long-term evaluation throughout the full-cycle of 14-month production period of a commercial cage farm operating in offshore conditions in the Black Sea area.
