Effect of different dietary protein sources on the growth performance of clarias gariepinus fingerlings


Okon, Anifiokmpong O; Ekwu, Alice. O; Akpan, Godwill. I; Umoh, Anthony N.

Growth performance and body composition of catfish (Clarias gariepinus) Fingerlings fed diets containing different protein sources (maggot meal (T1), crayfish dust meal (T2), fish meal (T3), blood meal (T4), soybean meal (T5), a combine protein sources (T6), at a level of 45% were studied for a period of 42 days. Fish fed diet containing maggot meal and fish meal as protein concentrates showed the maximum weight gain, highest daily growth and specific growth rate of 0.80% 3.33, 3.53. Respectively. The optimal body condition (0.76) was observed for maggot meal. The diets containing soybean and the combined protein sources did not show any significant different (p<0.05) between each other. The blood meal diet showed the least value of daily growth rate (0.03), specific growth rate (2.16), feed conversion ratio (11.10): net protein retention (NPR) (87.67), while the diet containing crayfish dust showed the highest net protein retention (NPR = 101.78). The result did not differ significantly among soybean and combined protein sources (p>0.05). While maggot meal and fish meal based diets perform better when compared with soybean and combined protein sources. Fish fed with all diet containing protein sources did not show any significant different (p>0.05) in their body moisture and fat contents. The study indicated that the sources of protein used in the diet affected the crude protein ash content of fish (p>0.05) and also revealed that protein source from fish meal, maggot meal and crayfish dust at the 45% level of inclusion can be utilized in the diet of Clarias gariepinus fingerlings to achieve optimal growth performance.
