研究了卤虫、Moina、Tubifex三种活体饲料和配合饲料对规格为(0.001.0 5±0.001.0 5)g的石斑鱼(Lates Calcarifer，又称Barramundi)幼鱼存活、生长和体成分的影响。配方饲料中添加了干孟买鸭鱼粉(10%)作为引诱剂。实验在40-L玻璃水族箱中进行了30天，水族箱内装有30只L淡水。投喂卤虫鱼苗的成活率最高(70%)，生长率最高(6.48±0.10%)。投喂卤虫鱼苗和配合饲料的成活率为60%，与投喂卤虫鱼苗的成活率差异不显著。喂食Tubifex鱼苗的成活率很低(30%)。不同处理间的体蛋白和体脂含量差异显著。本研究表明，卤虫无节幼体是生长和存活相似的饲料，但配合饲料可以作为替代饲料。
The effects of the live feeds, Artemia, Moina, and Tubifex, and a formulated diet on the survival, growth, and body composition of fry (0.05±0.001 g) of the Asian sea bass, Lates calcarifer (also called barramundi), were evaluated. The formulated diet was supplemented with dry Bombay duck fishmeal (10%) as an attractant. The experiment was conducted for 30 days in 40-l glass aquaria containing 30 l fresh water. The fry fed Artemia had the best survival (70%) and growth rate (6.48±0.10%). Fry fed Moina and formulated diet had 60% survival, not significantly different from fry fed Artemia. Survival was poor (30%) in fry fed Tubifex. Body protein and lipid contents differed significantly among treatments. The present study suggests that Artemia nauplii is the better feed for Asian sea bass fry but formulated diet can be used as a substitute since growth and survival were similar.
