An Apparent Digestibility Coefficient (ADC's) of crude protein, lipid and energy in differently processed lima bean (Phaseoluslunatus) were determined for Clarias gariepinus. Raw (RLM), boiled (BLM), soaked (SLM), autoclaved (ALM) and toasted (TLM) Lima bean were the test ingredients. Test diets contained 70% reference diets and 30% of test ingredients, with chromic oxide as the inert marker. All treatments were replicated. Fish were fed twice daily and excess feed siphoned out 30 mm after each feeding, while faecal collection was done 8 h after every feeding. The least ADC phosphorus value was recorded in RLM. ADC's lipid was highest in BLM and showed significant difference with SLM and ALM. FCR for ALM varied significantly from other treatment. Clarias gariepinus can effectively digest boiled and toasted Lima bean seed, with both treatments having better ADC's for protein, lipid, energy and phosphorus.
