The present study was conducted to investigate the effects of fenugreek seed meal ( FKSM ) on growth performance, blood haematological and biochemical factors, survival and stress resistance of the common carp (2.46 ± 0.06 g) fingerlings. Four practical diets containing 0 (control), 0.5%, 1% and 1.5% FKSM were used to feed fish. Fish were fed on the tested diets at a rate of 3% of body weight for 8 weeks. Results indicated that fish fed the control diet had a significantly lower weight gain, specific growth rate and condition factor compared to the other treatments ( P < 0.05). Feed conversion ratio decreased significantly in fish fed diets containing FKSM . There were no significant differences in glucose levels, red blood cell count, haematocrit and haemoglobin between treatment groups and the control group ( P > 0.05). Significantly lower white blood cells count was observed in fish treatment with FKSM when compared with the control group ( P < 0.05). The cholesterol level in group fed supplemented diet by 1% fenugreek significantly lower than other groups ( P < 0.05). Total protein levels were significantly higher in all treatments compared to the control ( P < 0.05). No mortality was recorded during the feeding trial. In salinity stress experiment, highest survival rate belong to fish fed supplemented diet by 1% fenugreek. These results indicate that FKSM can be considered as a beneficial dietary supplement for improving the growth performance and blood indices of common carp fingerling.
