摘　　要：对云斑尖塘鳢(Oxyeleotris marmorata)幼鱼在3种不同放养密度下的生长速度和成活率进行了对比试验。培育60 d后的调查结果表明,密度为每667 m2水体放养30 000尾比放养10 000尾或50 000尾更为合适,幼鱼成活率分别为91.3%、88.9%和85.7%。Growth and survival rate of Oxyeleotris marmorata fry in 3 kinds of feeding density were studied. The results showed that the density of 30 000 individuals per 667 m^2 is more suitable than the density of 10 000 individuals or the density of 50 000 individuals in 60 days of test. The survival rate of three graups were 91.3%,88.9%and 85.7% respectively.
