The Effect of Feeding Frequency on Growth Performance and Feed Conversion Rate of Black Sea Trout (Salmo trutta labrax Pallas, 1811)

Growth, feed consumption and conversion ratios of Black Sea trout (Salmo trutta labrax Pallas, 1811) subjected to daily feeding frequencies were evaluated. The trial performed using 360 fish with a mean weight of 155.9+/- 31.56 g was sampled, counted and divided equally to nine tanks. The three trea...

description Growth, feed consumption and conversion ratios of Black Sea trout (Salmo trutta labrax Pallas, 1811) subjected to daily feeding frequencies were evaluated. The trial performed using 360 fish with a mean weight of 155.9+/- 31.56 g was sampled, counted and divided equally to nine tanks. The three treatments (namely, daily feeding frequencies of one - F, two - F2 and three - F3) were each applied to three tanks. Mean live weights of the fish in trial groups reached 201.7+/-3.42 g, 202.7+/-3.18 g and 217.6+/-2.54 g at the end of the trial in groups F, F2 and F, respectively. Growth data indicated that, the final live weight and SGR values of group F3 were significantly higher than those of the other groups (P
