摘要: 报道了蒙古裸腹氵蚤(Moinamongolica)在20℃~33℃温度和5~40ppt盐度条件下的种群内禀增长率(rm).结果表明,20℃~30℃范围内蒙古裸腹氵蚤rm随温度升高而升高,超过30℃后继续升温,rm显著降低;在低盐度下蒙古裸腹氵蚤的种群增长能力相对较强,盐度为10ppt时rm最高,20~40ppt范围内氵蚤的rm差别不明显.本实验表明,25℃~30℃和10ppt分别是蒙古裸腹氵蚤种群增长较快的温度和盐度条件,在海水中长期培养对蒙古裸腹氵蚤的种群增长能力不会产生明显的不良影响.

Abstract: The intrinsic increasing rate of Moina mongolica Daddy,a euryhaline cladocera species isolated from inland brackish lakes of northwestern China,was studied at 20℃~33℃, 5~40ppt,respectively.The results showed that its intrinsic increasing rate(rm) increased with increasing temperature from 20℃~30℃,and sharply dropped with further increasing temperature up to 33℃.The rm of M.mongolica was relatively high at low salinity,the highest at 10ppt,but no significant difference at 20~40ppt.Therefore,25℃~30℃, 10ppt could be optimal for the development of M.mongolica population,and its increasing potential would not be affected significantly by rearing this cladocera species in seawater for a long period.

Key words: Moina mongolica, Intrinsic increasing rate(rm), Temperature, Salinity
