The Effect of Water Current on Nutrient Components of Rainbow Trout (Oncorhynchus mykiss)


Abstract: 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 l 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 betwen Groups in term of protein (P<0.05) but not between the other nutritional components (P>0.05).
