摘　　要：为确保水产“质量安全”、“生态安全”，帮助渔农正确使用饲料，大力推广科学养鱼模式，使养殖户获得更大效益，试验组在贵州罗甸县茂井镇龙滩库区罗甸星火科技水产公司的网箱基地，从2009年9月2日．11月3日，在6口钢管架网箱内（25平方米、62.5m3／口），进行了为期64d投喂通威152浮性颗粒料养殖罗非鱼（149．64±5．28g）试验。试验结果表明：投喂通威152浮性饲料养殖罗非鱼成活率达96．47±0．34％，饲料系数为1．23±0．81，具有饲料系数低、养殖投喂劳动强度低的优势，养殖模式值得推广。The experimental group, in order to ensure safety of both quality and ecology, and help fish farmers to use feed products adequately, while promoting the model of culturing fish vigorously, so as to bring more profits to farmers, make an experiment with Tongwei Floating Feed in the net cage fish farming base in Luodian Spark Sci. ＆ Tech. Aquaculture Company, situated at Longtan Reservoir, Maojing Town of Luo Dian County of Guizhou Province, from Sept. 2 to Nov. 3, 2009. The experiment Of feeding Tongwei 152 Floating Pellet Feed to tilapia is undertaken in 6 net cages consisting of steel tube frames （25 sq. meters, 62.5 m3each ） with the period of 64 days. The results show that, feeding Tongwei 152 Floating Pellet Feed to tilapia can bring about the optimum survival rate and FCR at 96.47±0.34% and 1.23±0.81 separately. The experiment proves that, Tongwei 152 Floating Pellet Feed has the advantages of lower FCR and reduced labour costs in culturing tilapia, and the culture model is worth extending among farmers.
