Özet
The aim of this study was to determine the growth performance, meat quality and colour attributes of large rainbow trout (Oncorhynchus mykiss) in net cage systems in the southern Black Sea coasts of Turkey. In the study, large rainbow trout with an initial weight of 1,322.07 +/- 57.72 g were reached to 3,385.30 +/- 140.98 g and the survival rates were 95.69 +/- 1.32% in 5-month production period. Crude protein and crude fat values of fish meat were ranged between 16.75 +/- 0.07-20.18 +/- 0.90% and 9.22 +/- 0.15-12.29 +/- 0.42%, respectively (p < .05). The essential and non-essential amino acid values were between 12.92 +/- 0.02-13.09 +/- 0.01 g/100 g and 11.97 +/- 0.14-11.47 +/- 0.01 g/100 g, respectively (p > .05). C20:5n-3, C22:6n-3, 3 and 6 values in fish meat were between 4.32 +/- 0.02-4.30 +/- 0.08% (p < .05), 8.31 +/- 0.10-7.72 +/- 0.15% (p < .05), 13.41 +/- 0.10-12.93 +/- 0.23% (p < .05) and 21.85 +/- 0.06%-19.74 +/- 0.36 (p < .05), respectively. As a result, it can be concluded that large rainbow trout cultured in the southern Black Sea coasts of Turkey is a rich source of food in terms of fatty and amino acid compositions and atherogenicity index, thrombogenicity index and hypocholesterolaemic/hypercholesterolaemic values.
