摘　　要：花点石斑鱼是一种名贵海产食用鱼,是海南网箱养鱼的主要种类。本文报道了用由下杂鱼(40%)、花生饼(20%)、米糠(22%)、海藻浆(15%)、饲料酵母(3%)和添加剂(适量)组成的湿颗粒配合饲料喂养花点石斑鱼的初步试验的结果。配合饲料中鱼类必需氨基酸纽成基本合理,营养价值较高,促进了鱼类的生长。配合饲料的投饲系数为4.9,而原来用下杂鱼投喂时的投饲系数为12.5。配合饲料的原料成本只是原来的58.9%。Being a precious marine product,Epinephelus maculatus(Bolch)is one of the major kinds of fish of marine cultivation by net pen in Hainan. This article reports a primary result of an experiment on feeding the fish with mixed feed.The damp pellet feed consists of small scale fishes(40%), peanut cakes(20%),rice bran(22%),sea weed paste(15%),feed yeast(3%) and a certain amount of premix.Owing to the basically ra- tio of the esential amino acid,the feed is of higher nutritional value. So it can feeilitate the grow of the fish.The feeding coefficient of the feed is 4.9.Compared to the original feeding coefficient of fishes,which is 12.5.The cost of the raw materia of the mixed feed is only 58.9% of that of the original feed.
