Abstract Length weight relationship and the diet of Clarias batrachus were investigated and 30 Clarias batrachus ( fingerlings) of sizes 0-20g of weight and 0-10cm of length were grouped into 3 tanks with replicates, they were fed for twelve weeks with local formulated feeds (guinea corn, maize, bone meal and groundnut) and Coppen. Tank A was fed with Coppen which served as control with a proximate analysis of 42% crude protein, 13% crude fat, 1.9% crude fibre and 8.9% ash while tank B has 22.0% crude protein, 10.09% fat, 3.51% crude fibre, 25.38% carbohydrate and 11.60% ash, and tank C with a proximate analysis of 25.2% crude protein, 8.9% fat, 6.9% moisture, 26.10% carbohydrate and 14.0% ash. They were fed at 4% body weight twice daily 6:00am-8:00am and 6:00pm-9:00pm, the growth performance and physiochemical parameters were measured weekly. The total weight and length were converted into log to find the relationship between the length and weight, length weight regression analysis gave an a,b and r value of 1.791,0.998 and -0.203 for tank A 1.778,0.999 and -0.197 for tank B while tank C had 25.59, 0.991 and -0.997. Results shows that the treatment fed with Coppen in tank A had the best growth performance while the treatment fed with substitute feeds in tank B and C show appreciable growth performance. The final mean weight gain were (0.535) for treatment A, (0.485) for B, while (0.475) was for C.
