Morphometric measurement of Dutch clarias fed with bambara nut and coconut chaff.

The length weight relationship and diet of Dutch Clarias was investigated in the University of Abuja, permanent site. 60 Dutch Clarias (fingerlings) of weight 0-20g and length (0-10cm) were grouped into three replicated tank, and fed for twelve weeks with a local formulated feed (Bambara nut and Coconut Chaff) and Coppen. Tank A had Coppen feeds which served as the control with a 42% crude protein, 13% Carbohydrate, 29% crude fibre, and 8% Ash, while Tank B has 42.25% protein, 48.41% Carbohydrate, 1.9% crude fibre, and 2.9% Ash, 10.8% crude lipid and 9.40% moist, fed Bambara nut and Coconut chaff at a ratio of 70to 30%. Tank C was served Bambara nut and Coconut chaff at a ratio of 30 to 70%, with an analysis of 42.18% crude protein, 58.37% Carbohydrate, 10.80% crude lipid, and 2.45% Ash, 0.5% crude fibre. Body and were fed 4% body weight twice daily (6 to 8 am, and 6 to 9pm). Their total weight and length were measured weekly and converted into log to calculate the relationship between them. Treatment A had a significant growth (p<0.05), followed by Tank B and C subsequently.
