为了提高暗纹东方鲀仔鱼的成活率,把已处理的池塘水、地下水混合成盐度为4～6的咸淡水,在咸淡水(试验池)中培育的暗纹东方鲀仔鱼比在淡水中(对照池)培育的仔鱼成活率高,平均成活率从31.82%提高到54.87%,差异显著。在试验中发现刚出膜3天的仔鱼能忍受从淡水至盐度6的突然变化,平均全长12 mm的稚鱼能忍受从盐度6至淡水的突然变化,处理后的咸淡水对暗纹东方鲀仔鱼和稚鱼是无毒、安全的,并发现稚鱼间的相互残食习性推迟和减轻了。
In order to improve the survival rate of Hylobates obscurus, the treated pond water and groundwater were mixed into salty freshwater with a salinity of 4-6, and the dark-shelled albino larvae cultured in brackish water (test pond) (Control pool) breeding larvae survival rate is high, the average survival rate increased from 31.82% to 54.87%, a significant difference. In the experiment, larvae newly exposed to the membrane for three days were found to tolerate abrupt changes from freshwater to salinity 6, and juveniles 12 mm in average tolerated abrupt changes from salinity 6 to freshwater, treated brackish water on dark The larynx and larvae are non-toxic and safe, and found that the habit of eating each other between juveniles is postponed and mitigated.
