Impact of feeding diets containing Luffa cylindrica seedmeal on the variable cost of production of African catfish, Clarias gariepinus (Burchell 1822)
This study investigates the use of Luffa cylindrica seed meal as soybean replacer in the diet of Clarias gariepinus. Five isonitrogenous diets containing soybean meal which was replaced by Luffa cylindrica at a rate of 0, 15,30,45 and 60% were made. The diets without Luffa cylindrical seed meal served as the control. Experimental diets were assigned randomly to the tanks and each group of fish was fed 5% body weight in equal proportion per day. The fish fed diet 1 had the highest incidence of cost, while the fish fed diet 4 had the lowest incidence of cost. There was no significant difference (P>0.05) in the incidence of cost of producing 1kg fish with the different dietary treatments. The fish fed at diet 4 had the highest profit, while the fish fed at diet 1 had the lowest profit. There was no significant difference (P>0.05) in the profit margin of producing 1kg fish with the different dietary treatments. The incidence of cost showed that it was cheaper to produce 1kg of fish with Luffa cylindrical seed meal because feeding the fish with the diet (control and tests diets) left some profit margin.
