| 摘 要： | 用轮虫、水丝蚓、鱼糜和配合饲料投喂40日龄的真鲷稚鱼,2d天后蛋白酶比活力以轮虫组为最高,鱼糜组次之,水丝蚓和配合饲科组活性极低;淀粉酶比活力以配合饲料组最高,轮虫和鱼糜组次之,水丝蚓蛆最低;脂肪酶比活力以配合饲料组最高,轮虫和水丝蚓组次之,鱼糜组最低.由试验结果看出,淡水的水丝蚓和以植物蛋白为主的配合饲料并非真鲷稚鱼的合适蛋白源;淀粉酶的活性明显受食物诱导,脂肪酶活性与食物脂肪含量呈负相关.研究结果对真鲷稚鱼投饵及配合饲料研制等有指导意义.

| Abstract: | Forty old Pagrosomus major juvenile had been feeded with Brachionus plicatilis. Limmodrillus. Harpodon nehereus gruel and plant mixed diet respectively for 2d. Then, the specific acitvity of protease was the highest in juvenile feeded with Brachionus plicatilis, the second with Harpodon nehereus, the non-activity with Limmodrillus and mixed diet. The specific activity of a-amylase was the highest with mixd diet, the sec- ond with Brachionus plicatilis and Harpodon nehereus, the lowest with Limmodrillus. The specific activity of lipase was the highest with mixed diet, the second with Brachionus plicatilis and Limmodrillus, the lowest with harpodon nehereus. It was suggested that Limmodrillus and plant protein were not fit to Pagrosomus ma- jor Juvenile, the activity of a -amylase was reduced distinctly by food, the activity of lipase was negative related with fat amount contained in food. |
