This study aimed to determine phosphorus requirements and phosphorus apparent digestibility coefficients (ADCP) of various ingredients in diets for snakehead (Channa striata) juveniles. Digestible phosphorus requirements were determined using seven iso-nitrogenous (45% crude protein) and iso-caloric (19.0 KJ g-1 ) diets with different dietary phosphorus levels ranging from 0.64% (Pdeficient control) to 2.15%. Phosphorus deficiency did not affect survival rate but reduced the specific growth rate by around 15%. The optimal dietary available phosphorus concentration for growth was 0.69%, which gave a specific growth rate of 2.46% day-1 . Fish fed the phosphorus deficient diet had significantly more body fat, a lower protein efficiency ratio, lower protein use and significantly lower calcium and phosphorus levels in their body, skeletal tissues and scales.
