摘要
分别用膨化饲料、粉料加鱼浆(6∶4)制成的湿软饲料、鲜杂鱼在深水网箱、小网箱中饲养大黄鱼,膨化饲料与湿软饲料在深水网箱中养殖的饲料系数分别为1.03和1.07,生长速度、成活率与鲜杂鱼组相当,公斤鱼成本低9.36%和6.01%,且投喂配合饲料后鱼体蛋白质和呈味氨基酸占氨基酸总量的比值无显著差别,以投喂膨化料比投喂粉料加鱼浆更经济些.
Offshore cage trials were conducted to compare the effect of expanded feedstuff, mixed feedstuff with powder-trash fish ratio of 6： 4, and trash fish for the growth of Psudosciaena crocea（Richardson）. The results show that the expanded feedstuff and mixed feedstuff can be used to substitute trash fish which is at present the main diet for the farmed Psudosciaena crocea （Richardson） , and the cost of expanded feedstuff is much lower.
