The effect of water current on nutrient components of rainbow trout (Oncorhynchus mykiss)

In this study, the effects of water current on nutrient components of trout (Oncorhynchus mykiss) were investigated. One year old fish averaging 550+/-0.06 g were used in the experiment which lasted for 3 months. In the experiment, the fish were reared in two tank of 1800 I each in the first tank (group A), water current was 1.5-2 fish length (25 cm)/sn while in the second tank (group B) there was no water current. In group A while the fillets contained 68.89+/-1.47 % dry matter, 19.71+/-0.66 % protein, 9.91+/-1.81 % lipit, the fillet of group B had 69.32+/-1.15 % dry matter, 19.37+/-0.58 protein and 9.84+/-1.32 % lipit. There was significant difference between Groups in term of protein (P<0.05) but not between the other nutritional components (P>0.05).
