Abstract

In this study, different produced extruded commercial Fish feeds in Chaharmahal-V-Bakhtiari Province investigated with the aim of determining Growth indices and carcass composition of fingerlings Rainbow trout. Total of 3600 Rainbow trout Juveniles with initial average weight of 80± 2. 4 gr, were subjected in triplicate to four diets of 1, 2, 3 and 4 and in a completely randomized design for 130 days. At the end of experiment, 10 fish (294. 7 7. 3 g) from each tank were randomly sampled and chemical carcass composition (i. e. protein, lipid, ash and moisture) were measured. The highest body weight gain and daily weight gain were calculated in treatment 1 compared to others (p<0. 05). Food conversion ratio (FCR) were lower in both 1 and 3 treatments than other groups (p<0. 05). The maximum crude protein of fish fillet was obtained in treatment 1 and the lowest was measured in treatment 2 (p<0. 05), but the fat content had not any significant differences among treatments (p>0. 05). The highest and lowest fillet ash percent was seen in treatments 1 and 2, respectively (p<0. 05). Treatments 1 and 2 were contained the highest and lowest amount of calcium and phosphorous, respectively (p<0. 05). In conclusion, Growth performances and carcass chemical composition of Rainbow trout were not similar which could be related different levels of crude protein of commercial diets, which produced in Chaharmahal-V-Bakhtiari feed factories.
