Abstract

A study was carried out in the Department of Fisheries and Aquaculture hatchery, Faculty of Agriculture, Prince Abubakar Audu University, Anyigba, Kogi State to determine the effect of different protein level diets on the growth performance of the African catfish (Clariasgariepinus) juveniles. Four experimental diets with various crude protein levels 25, 35, 45 and 55% were formulated using trial and error method. One hundred and eighty juveniles of African catfish of initial weight of 8.75g were distributed in twelve circular plastic containers: each container stocked with ten fishes fed with the four formulated diets for six weeks and each treatment replicated thrice. The result showed that the fish fed with highest protein (55%) level had the highest final weight (18.24 g) and weight gain (1.94g), while the fish fed with lowest protein (25%) level had the lowest final weight (13.55g) and weight gain (1.29g) The specific growth rate, protein efficiency ratio and food conversion ratio were recorded as 0.62 ± 0.24, 0.79 ± 0.03, and 5.08 ± 0.35respectively. The result showed an increase in growth indices with increase in dietary protein levels. Most of the growth indices such as mean weight gain (MWG) specific growth rate, (SGR), mean daily weight gain (MDW) and food conversion ratio (FCR), were higher (P>0.05) in juveniles fed with 55% crude protein. Higher dietary protein level was observed to give higher growth rate in this study and it is therefore recommended that juveniles of the African catfish are ought to be fed with higher protein level (55%) diet for optimum production.
