The growth performance of African catfish Clarias gariepinus (Burchell 1822) juveniles fed differently processed toad meal based diets was investigated in this study. Toads were collected gutted washed and processed into meals using four different methods namely: oven drying at 60 C (treatment 1); oven drying at 100 C (treatment 2); removal of the skin and parotid gland before oven drying at 60 C (treatment 3); and fermentation for 3 days before oven drying at 60 C (treatment 4). Five isonitrogenous diets of 35 crude protein were formulated with inclusions of the processed toad meals (treatments 1 2 3 and 4) and a control diet with inclusion of fish meal (treatment 5). These were fed to juveniles of C. gariepinus (mean weight 13.08 0.01 g) for 56 days. The results reveal that treatment 3 gave the best growth parameters even more than the control diet with inclusion of fishmeal. This is further supported by the result of carcass analysis which revealed a similar trend. The cost analysis also confirms the superiority of treatment 3 over the other treatments due to its ability to produce 1 kg of fish with far less money than the other diets. The least growth indices carcass protein and cost effectiveness were observed with dietary inclusions of fermented toad meal (treatment 4). It was therefore concluded that dietary inclusions of skinned and deglanded toad meal improves performance and production characteristics of the African catfish.

Abstract

The growth performance of African catfish Clarias gariepinus (Burchell 1822) juveniles fed differently processed toad meal based diets was investigated in this study. Toads were collected gutted washed and processed into meals using four different methods namely: oven drying at 60 C (treatment 1); oven drying at 100 C (treatment 2); removal of the skin and parotid gland before oven drying at 60 C (treatment 3); and fermentation for 3 days before oven drying at 60 C (treatment 4). Five isonitrogenous diets of 35 crude protein were formulated with inclusions of the processed toad meals (treatments 1 2 3 and 4) and a control diet with inclusion of fish meal (treatment 5). These were fed to juveniles of C. gariepinus (mean weight 13.08 0.01 g) for 56 days. The results reveal that treatment 3 gave the best growth parameters even more than the control diet with inclusion of fishmeal. This is further supported by the result of carcass analysis which revealed a similar trend. The cost analysis also confirms the superiority of treatment 3 over the other treatments due to its ability to produce 1 kg of fish with far less money than the other diets. The least growth indices carcass protein and cost effectiveness were observed with dietary inclusions of fermented toad meal (treatment 4). It was therefore concluded that dietary inclusions of skinned and deglanded toad meal improves performance and production characteristics of the African catfish.
