The requirements of black sea bream, Sparus macrocephalus, for calcium, phosphorous, potassium, magnesium and manganese were studied using semi-purified diets and orthogonal design. Based on the fish weight gains, survival rates and the contents of the minerals in the fish liver, the proper contents of phosphorous and manganese in the fish diets are 0.99% and 60 mg/kg, respectively. Supplementation of calcium, potassium and magnesium in the diets is not necessary.
