软质饲料与鲜杂鱼饵料饲养大黄鱼对比试验

为比较研究网箱养殖大黄鱼过程中分别投喂软质饲料与鲜杂鱼饵料的养殖效果,2011年5月于福建省马鼻玉井网箱养殖海区,选取平均规格为152 g/尾的大黄鱼,经过60 d的饲养,试验组全投软质饲料,对照组全投鲜杂鱼。结果显示：试验组与对照组每尾平均体重分别为256.9 g、231.3 g,饲料系数分别为2.505、7.306,大黄鱼每增重1 kg所需的饲料成本分别为15元、19.7元,投喂软质饲料进行饲养可节省成本4.7元。结果表明：投喂软质饲料的养殖效果优于鲜杂鱼,存活率更高,更具环保等综合效益。

Contrast experiment on feeding Pseudosciaena crocea with soft feed and fresh trash feed

To compare the culture effects of two kinds of diets：soft artificial diet and fresh trash fish used to feed Pseudosciaena crocea cultured in the net cage, the test was carried out in Mabi Yujing Cage Culture Area, Fujian Province, in May 2011 by selecting the average size of 152 g each individual of Pseudosciaena cro-cea. After 60 days’ feeding, the average weight of each Pseudosciaena crocea respectively were 256. 9 g for the group fed with soft artificial diet and 231. 3 g for the group fed with fresh trash fish;the average feed coef-ficient respectively were 2. 505 for soft artificial diet group and 7. 306 for fresh trash fish group;the culture-cost for 1 kg gain weight of Pseudosciaena crocea respectively were 15 yuan for test group and 19. 7 yuan for control group, saving 4 yuan. The results indicated that the Pseudosciaena crocea fed with soft artificial diet had the better culture effect, the higher rate of survival and more environmental protection and other compre-hensive benefits.
