摘　　要：于1988年7月—8月和1989年7月—8月，以酪蛋白为蛋白源，采用蛋白含量梯度法进行黑鲷饲料中最适蛋白质含量研究。结果表明，黑鲷幼鱼饲料中，蛋白质的最适含量约为50．19％。1988年8月—9月和1989年8月—9月，以玉筋鱼为动物蛋白源，以花生饼粉为植物蛋白源，饲料中总蛋白质含量相等，进行黑鲷饲料中最适动、植物蛋白比研究。结果表明，黑鲷幼鱼饲料中，动、植物蛋白的最适比例为1.00：0.89－0.96。An experiment on the optimum protein content in the diet of the black seabream (Sparus macrocephalus) was carried out from Jul. 15 to Aug. 14, 1988 and Jul. 15 to Aug. 14, 1989 at the Aquarium of the lnstitute of Oceanology, Acade-mia Sinica. The protein gradient method was employed, using casein as basic diet and dextrin as the energy source. The results showed that deficiency or excessive content of protein in the diet causes slow growth and high expense for food. It is inferred from tbe growth rate and food consumption of the fish that the approp-riate value of protein content in the black sea bream diet should be about 50.19%.Another experiment on the optimum ratio of animal to plant protein in the diet of the black sea bream was carried but from Aug. 15 to Sept. 14, 1988 and Aug. 16 to Sep. 15, 1989. Sand eel was used as the animal protein source, peanut cake meal as plant protein source. The resuIts showed that the appropriate ratio of animal to plant protein in the diet should be 1.00:0.89-0.96.
