Description:
A 35-day feeding trial was conducted to compare and evaluate nine first feeds for Clarias gariepinus. The nine feedingstuff materials contained more than 40% crude protein. Artemia, coppens and fishmeal were used as single protein sources. Fish egg meal, cattle liver meal and shrimp meal were supplemented with yeast alone or yeast combined with folic acid. Twenty fish larvae were kept in plastic bowls with replicate for each treatment inside the laboratory. Feeding commenced after yolk absorption. Each diet was fed to fry twice daily to apparent satiation. Percentage survival at the end of the experimental period ranged between 0% and 100% for fish on fish egg supplemented with yeast and folic acid and liver meal with yeast respectively. Fish fed artemia had the highest weight while those on shrimp meal supplemented with yeast had the least. Highest specific growth rate was in fish fed fish egg supplemented with both folic acid and yeast. The cost of rearing Clarias gariepinus larvae can be appreciably reduced by using non conventional protein sources, which are locally available, for feed preparation.
