本文报道在云南南亚热带山区大水体池塘中，用人工施肥培养浮游动物，作为革胡子鲶稚鱼（文中简称稚鲶）的开口饵料及其形成夏花鱼苗（３ｃｍ以上）的动物性饲料是可行的。对孵出四日龄的稚鲶进行培育，在水温２３．２—３０．３℃时，可使十七日龄稚鲶达到夏花水平，存活率达６０％以上。研究结果表明，四日龄稚鲶口宽为７６０—９００μｍ，开口期及生长前期（十三日龄前）主要摄取枝角类、桡足类和摇蚊幼虫。稚鲶生长后期（十三日龄后），对轮虫、水生昆虫动体及配合饲料的摄取量增加，而摄食枝角类、桡足类和摇蚊幼虫数量相对减少。培育期稚鲶摄食率达９０％以上，胃囊充塞度多在３—５级。稚鲶的体长与日龄呈直线相关，体重与日龄和体长对体重呈幂函数关系，稚鲶体长呈均速递增，体重呈加速增长。 This paper reports that it is feasible to cultivate zooplankton by artificial fertilization in the large water body ponds in the south subtropical mountainous area of ​​Yunnan Province as the feed for the open juveniles of juvenile catfish (herein referred to as juvenile catfish) and the animal feed for forming summer fry (3 cm or more) of. Four-day-old juvenile hatchlings were incubated at water temperature 23.2-30.3 ℃, the juvenile catfish can reach the age of 17 days summer flower levels, the survival rate of 60% or more. The results show that the four-day-old juvenile catfish mouth width of 760-900μm, the opening and pre-growth stage (before the age of 13 days) mainly take cladocera, copepods and chironomid larvae. In late growth stages (after 13 days), juvenile catfish increased its intake of rotifers, aquatic insects and feed, while the numbers of cladocerans, copepods and chironomid larvae decreased. Incubation period juvenile catfish feeding rate of 90% or more, the degree of gastric bag congestion in 3-5. The body length of juvenile catfish was linearly correlated with age. The body weight showed a power function with age and body length. The body length of juvenile catfish increased with increasing speed and the body weight increased rapidly.
