本文就九龙江口几种常见桡足类在不同盐度海区中的分布,结合实验研究结果来探讨桡足类和盐度的关系。每种桡足类具有一定的盐度范国,包括耐盐的高、低阀值。在其适盐范围内,盐度的变化并不影响动物的存活率,但超过了这一范围,存活率不同程度地明显下降,中华异水蚤雌性和雄性、中华哲水蚤雌性、瘦尾胸刺水蚤雄性和太平洋纺锤水蚤雌性的存活率和盐度呈线性相关。海区桡足类分布的盐度范围和实验数据比较接近。盐驯化对动物的耐盐能力有提高作用。
In this paper, the distribution of several common copepods in different salinities in the Jiulong River Estuary was studied. The relationship between copepods and salinity was discussed based on the experimental results. Each copepoda has a salinity range, including high and low salt tolerance. In its suitable salt range, the salinity changes did not affect the survival rate of animals, but beyond this range, the survival rate decreased to varying degrees, the female and male Daphnia magna, Crocodylia crassipes female, thin tail There was a linear correlation between the survival rate of saliva and the salinity of male Spiraea flea and Pacific spinous Daphnia. The salinity range of copepods distribution in sea area is close to the experimental data. Salt domestication on the salt tolerance of animals to improve the role.
