Abstract :
The present study was carried out the effect of sex, length and weight on protein, fat, ash and fillets moisture content in Ctenopharyngodon idella. For this purpose, 10 fish were obtained from each of 20, 100 and 500 g weight groups and longitudinal groups of 10, 22 and 35 cm. The results showed significant differences in protein content, fat, moisture and ash content of fish fillets at different weights and lengths (P<0.05). Protein and fat levels were significantly higher in the 100 and 500 g groups than in the 20 g group (P<0.05) and there was no significant difference between the 100 and 500 g groups (P>0.05). Fillet moisture and ash content were significantly higher in the 20 and 100 g weight groups than in the 500 g group (P<0.05). Their values were 10 cm in the group (P<0.05) and there was no significant difference between groups 22 and 35 cm (P>0.05). Fillet moisture and ash content in the 10 and 22 cm lenght groups were significantly higher than those in the 35 cm groups (P<0.05). On the other hand, the results of analysis of fillet composition in male and female showed that protein, fat, moisture and ash content of fish fillets in male and female were not significantly different (P>0.05). In general, we can say that length and weight had significant effect on fillet composition in grass carp, but gender had no significant effect on fillet composition.
