摘 要 ：在实验室条件下(25℃),笔者对采自美国旧金山、我国天津、山西的3种卤虫的无节幼体和成体对饥饿的耐受性进行了研究。3种卤虫的雌性成体在饥饿状态下的平均存活时间的差异不显著。它们的无节幼体在饥饿状态下平均存活时间差异显著,时间长短依次为:As>Ap>Af。无节幼体存活时间的长短与3种卤虫的卵径的大小及刚孵出时的大小无关,但与它们在饥饿期间的平均生长率及平均增加的体长呈负相关。对3种卤虫无节幼体饥饿耐受力所进行的方差分析和Tukey法多重比较的结果表明,同为两性生殖种的Af和As之间的差异超过它们与孤雌生殖的Ap的差异。

Abstract:The tolerance to starvation of nauplii and adult females of three species of brine shrimps, Artemia franciscana(Af), parthenogenetic Atemia from Tian-jin, China(Ap) and bisexual Artemia from Shanxi, China(As), were examed at 25℃ in laboratory. The three species of Artemia belong to New World . sexual population, parthenogenetic population and Old World sexual population, respectively.The mean survival times of starved adults of all three species were not significantly different. However, their nauplii showe...
