| 摘 要： | 对一龄草鱼种培育池的水质数据采用生物统计法,以其单因子或多因子与草鱼病毒性出血病的关系进行分析比较。结果表明,出血病与某些生态因子密切相关。当水温逐渐升高时,溶氧和透明度的下降或总氮和有机氮等的升高,均易引起出血病的发生和流行。其中溶氧是诸因素中主要的发病因素,水温是发病的首要条件,其它理化因素也可成为发病因素;与水质密切相关的浮游生物量的升高或剧变对出血病有一定影响;底质含氮物高会引起水质恶化,继而导致发病。

| Abstract: | Based on the data of water quality measured in the nursery ponds for one-year-old fingerlings of grass carp, the relationship between one or multiple water quality factors and viral hemorrhagic disease has been analyzed. The results, which were concluded by means of biological statistics, showed that breakout of the disease is closely related to some ecological factors. When water temperature rised gradually, the factors which were liable to the breakout and prevailing of the disease included increase of to... |
