Effect of organic and inorganic diet in the growth of Clarias gariepinus

Abstract

Twelve weeks (three months) experiment was conducted in the Department of Biological Science at University of Abuja Main Campus to monitor the study of the effect of organic and inorganic diet on the growth of Clarias gariepinus. It was conducted between October to December, 2012 using circular tanks of diameter 63 cm, radium 3.5 and circumference 198 cm with water retention capacity of 70 litres. 30 fingerlings of Clarias gariepinus of mean weight 0.8 g and mean length 0.59 cm were divided into three tanks A, B, C, with each tank having 10 fish. The fishes in Tank A where fed with organic diet (Coppens) with proximate analysis of 42% crude protein, 13% crude fibre, and 6.79% ash. 50% of organic diet (chicken dropping) in Tank B with a proximate analysis of 12.57% of moisture, 30% of crude protein, 15.10% of fats, 2.35% of crude fire and 5.6% of ash together with a combination of organic and inorganic diet in Tank C (with proximate analysis 4.2% crude protein, 13% of crude fibre and 6.7% of ash) were fed at 4%  body weight twice daily.
