The influence of water salinities of 3, 5, and 7 ppt on the growth and survival of (L.) larvae was studied. The control group was fish reared in freshwater (0 ppt). The larvae showed high tolerance to water salinities of 5-7 ppt. The mean final weight of the larvae ranged from 48.6 to 64.1 mg, with corresponding mean total lengths from 18.9 to 22.6 mm, depending on the water salinity level. The best larval length increments were recorded in water with salinity of 3 ppt. They were only slightly lower in 0 ppt water, and there were no statistically significant differences between the breeding rates calculated for larvae reared in 3 ppt water. Depending on the salinity level of the water, the final survival rate of the blue bream larvae ranged from 83.5 to 98.6%. The blue bream larvae reared in water with salinity levels of 5 and 7 ppt were statistically smaller than the others, but the results obtained were equally satisfactory.
研究了盐度为3、5和7ppt的水对蓝鳃太阳鱼（L.）幼鱼生长和存活的影响。对照组是在淡水（0ppt）中饲养的鱼。幼鱼对5-7ppt的水盐度表现出较高的耐受性。根据水盐度水平，幼鱼的平均最终体重在48.6至64.1毫克之间，相应的平均全长在18.9至22.6毫米之间。在盐度为3ppt的水中记录到幼鱼最佳的体长增长。在0ppt水中仅略低，并且在3ppt水中饲养的幼鱼的繁殖率计算之间没有统计学上的显著差异。根据水的盐度水平，蓝鳃太阳鱼幼鱼的最终存活率在83.5%至98.6%之间。在盐度水平为5和7ppt的水中饲养的蓝鳃太阳鱼幼鱼在统计学上比其他幼鱼小，但获得的结果同样令人满意。
