低氧对中华哲水蚤存活和繁殖影响的实验研究
The effects of hypoxia on survival and reproduction of Ca-lanus sinicus
摘要
Abstract
The mortality rates and reproduction of Calanus sinicus at different concentration of dissolved oxygen (DO) were investigated. The results showed that when DO declined to 2 mg/L, C. sinicus all died in 1 h. When DO declined to 3 mg/L, C.sinicus all died in 96 h. When DO was 4-6 mg/L, basically there was no death. But the spawning rate of C. sinicus could be significantly inhibited under this hypoxia condition.When DO was 4 mg/L, almost no spawn. When DO was 6 mg/L, the total spawning amount was only 15% of nornoxic group. When DO was 4-6 mg/L, the hatching rate was 60% of nomixic group. Therefore, hypoxia inhibits both survival and repro-duction of C. sinicus. Long time hypoxia would reduce the population quantities of C. sinicus and even change the structure of ecosystem.关键词
