Author(s): John Amadi, Sorbari Victory, Bob Manuel3, Fayeofori G
Abstract: A trial feed was formulated to substitute fish meal with blood meal in the diets of Clarias gariepinus fingerlings. Five iso-nitrogenous diets containing crude protein with four replicates in which blood meal was boiled, sundried and mixed with other available materials at varying inclusion levels (10%,15%,20%,25% and 30%) respectively. The analysis of the fish carcass revealed that the diet E with 30% substitution of fish meal with blood meal had the highest protein (52.31%) followed by diet D (blood meal only) 50.43% and finally diet F (control fish meal only) 49.79. In weekly weight increase, diet E with 30% inclusion level had the highest mean weight value of 41.28g followed by diet F (control fish meal only) and diet D with 25% (37.96g), while in weekly increased in length, diet E had the highest increase mean with 8.39cm>diet F 8.13cm > diet D 7.94cm > diet C 6.93cm> diet A 4.95cm. The result therefore are indicative of the fact that the blood meal can serve as fish meal replacers at 30% substitution level without adverse effect on the fish weight, length increase and improve carcass protein.
