Growth performance, haematological and biochemical study of <i>Clarias gariepinus</i> (Burshell) fingerlings fed formlulated <i>Rana galamensis</i> (Galam) meals

Abstract

A 56-­‐day feeding experiment involving Clarias gariepinus fingerlings was conducted to investigate the growth response, serum and biochemical parameters of the fingerlings to formulated feed from Rana galamensis at 0%, 10%, 20%, 30% and 40% inclusion levels. 180 fingerlings were divided into 5 treatment groups containing 36 fingerlings and each group was further replicated 3 times. A significant difference (P<0.05) was established in the growth parameters determined in the C. gariepinus fingerlings fed with the four frog formulations, namely, final weight, total weight, and mean feed gain, mean weight gain and feed conversion ratio The 40% R. galamensis ration elicited higher growth values than all other rations. Similarly, significance difference (P<0.05) was established in the serum (Total protein, Albumin and Cholestreol) and biochemical (Na+. K+ and HCO3 -­‐) parameters determined in the blood samples collected from the fingerlings fed with the four frog formulations. The increasing values observed in the growth factors, serum and biochemical parameters of the fingerlings when increasing level of R. galamensis protein was incorporated into the fish diet is an indication that the formulated feed can serve as growth promoter as well as rich sources of mineral supply to the fish; hence, a potential protein source for aquacultural practices.
