| Abstract | ||
| Animal protein was replaced by plant protein ( lemna sp.) ) in proportions of 30% , 60% and 100% in the diet of the common carp (cyprinuscarpio ) fingerlings under experimental conditions ,four treatments were used , T1 represents control , T2 30% replacement of lemna sp., T3 60 % replacement of lemna sp. , T4 100 % replacement of lemna sp. Results showed that the final weigh gain were (196 , 185 , 172 , 95) g the four treatments respectively . While the daily growth rate was (0.26 , 0.25 , 0.23) g / day / fish , the specific growth rate was (1.17 , 1.13 , 1.08) % g / day . Statistical analysis showed there were no significant differences in the food conversion rate between the control treatment with the treatments of partial replacement (T1 , T2 , T3 ), they were (3.4 , 3.5 , 3.7) respectively , while the parameters values decreased in the total replacement treatments above mentioned were daily growth rate (0.16) ) g/day/fish , specific growth rate (0.82) %g /day , food conversion rate (4.6) .Hence these percentage could be recommended for replacement to reduce the cost of the diet . However the total replacement of 100 % is not recommended because of the high statistical differences in the growth parameters between the control and T4 of the common carp fingerlings | ||
