香鱼人工育苗饵料系列及投喂技术研究

在水温14．8-21．2℃,比重1．008-1．013条件下,采用轮虫、微颗粒饲料、卤虫无节幼体及桡足类,以不同配比组成3组不同的饵料系列投喂香鱼仔、稚鱼。结果表明:采用轮虫 配合饲料-桡足类 配合饲料的系列饵料,在仔稚幼鱼生长速度和成活率等方面优于单纯使用生物饵料组成的饵料系列,并且可以降低育苗成本。

Study on the Feeding Technique of Plecoglossus altivelis

Three groups of dietary which were prepared according to different ratio were fed respectively to the fry and the juvenile under the water temperature 14.8 to 21.2 centigrade and the specific gravity 1.008 to 1.013. The result indicated that the growth and survival of the group which fed on rotifer plus compound feed and copepod plus compound feed was higher than the group which feed on organic feed only. Moreover, the cost for the former was lower.
