Assessment of proper stocking density for better growth in small culture system of an african catfish Clarias gariepinus (Burchell) in indian climatic condition

摘要

Clarias gariepinus (Burchell) fingerlings with initial wt. of 21-23 g were stocked at densities of 24m~(-3), 48m~(-3) and 72m~(-3) in three separate tanks and cultured for about 11 months. Final wt. achieved were 352 g, 1000 and 730g in 24m~(-3), 48m~(-3) and 72m~(-3) stocking densities respectively. The highest growth was observed in the stocking density of 48m~(-3) as against the lowest growth in the density of 24m~(-3) and medium growth in the stocking density of 72 fishes m~(-3).
