Two experiments were conducted to assess the effect of organic and inorganic fertilizers on natural food composition and performance of African catfish (Clarias gariepinus) fry produced under artificial propagation. In both experiments chicken manure, di-ammonium phosphate and no fertilizer were used as treatments. The first experiment was conducted to determine the abundance and diversity of natural food produced in tanks fertilized with chicken manure and di-ammonium phosphate fertilizer. The second experiment was conducted to assess growth performance and survival of catfish fry produced in chicken manure and di-ammonium phosphate at 5fry/m2 and 10fry/m2 stocking densities. Nine concrete tanks and eighteen concrete tanks were used in experiment 1 and 2, respectively. The results indicated that abundance of natural food (phytoplank.. View More»
