摘　　要：本文观测了一种新近发现的卤虫品系——山西解池硫酸盐湖卤虫品系。这是一种两性生殖卤虫,其雌/雄约为1/0.8,其卵和无节幼体明显比孤雌生殖卤虫的小,孵化率约75%。可直接将盐度为270‰的湖水中的卤虫移入盐度为32‰的自然海水中,存活良好。其无节幼体投喂对虾幼体的饵料效果良好,存活率达60—70％。A newly found Artemia strain from a sulfate lake-Xiechi Lake in Shanxi was examined. The strain was bisexual with a females to males ratio of 1: 0.8. The size of the eggs and nauplii of Xiechi strain was significantly smaller than the parthenogenetic strain. The hatching efficiency of the eggs was about 75%. The animals from the lake (s:270%) were able to live well when removed into the natural sea water. A good result was provided for penaeid shrimp larvae fed with the nauplii of Xiechi strain. The survival rate of penaeid shrimp was about 60-70%.
