摘　　要：根据石斑鱼仔稚鱼的营养需求,精选原料,筛选配方,研制出石斑鱼仔稚鱼微粒子配合饲料,通过测定其散失率和沉降速度,筛选出较适宜的粘合剂配方为褐藻胶1.5%,胶原蛋白3.5%混合使用。分析石斑鱼仔稚鱼微粒子配合饲料的脂肪酸和氨基酸组成,结果表明其n3HUFA组成占19.4%,与小球藻轮虫的20%～28%非常接近;10种必需氨基酸的组成合理。所研发的饲料安全限量符合NY5072《无公害食品渔用配合饲料安全限量》的要求,第20d到第45d,投喂微粒子配合饲料的点带石斑鱼鱼苗成活率3.3%,优于对照组的3.1%。Based on the nutritional requirement of larva and juvenile of Epinephelus coioides,with selecting raw material and screening various formulations,micropaticle diets for Larva and Juvenile of Epinephelus coioides were developed.The adhesive ingredient was studied through the research of its lost ratios and settling velocity.The results showed that the optimum ingredient was combination of 1.5% algin and 3.5% collagen.Fatty acid and amino acid compositions of microparticle diets were analyzed.The results indicated that the composition of n3 high unsaturated fatty acid was 19.4%,close to Chlorella wheel worm（20%～28%） and the ten kinds of essential amino acid compositions were reasonable.The safety level of microparticle diets met the standard requirement of NY5072-2002.From 20th to 45th day,the survival rate of Epinephelus malabaricus which fed with microparticle diets was 3.3%,better than control group.
