本文报道了不同盐度对褶皱臂尾轮虫存活及其休眠卵孵化的影响。采自低盐度（４‰）和较高盐度（２０‰左右）水体中的褶皱臂尾轮虫休眠卵，在纯水和５０‰的高盐度孵化液中都不能孵化，但在淡水和５—４０‰盐度的孵化液中均有不同比例的孵化，其中以５‰盐度中的孵化率最高。采自２０‰盐度的休眠卵在１５‰盐度中孵化的幼轮虫在５—３０‰盐度中，３小时内，其存活率均达９０％以上，不必通过驯化，可直接投喂到不同盐度的育苗池。而采自４‰盐度的休眠卵５‰盐度孵化的幼轮虫，在２５‰、３０‰盐度中存活不到２０分钟；４‰盐度的休眠卵，适当提高孵化液的盐度，在１０‰盐度中孵化的幼轮虫，３小时内，在３０‰盐度中存活率达８０％。本实验主要在室内进行，并在庄河市观驾山水产养殖公司室外土池培养轮虫实践中获得成功，初步解决了利用低盐度休眠卵培养轮虫作为活饵料向３０‰盐度水体的投喂问题
In this paper, the effects of different salinities on survival and resting egg hatching of Brachionus plicatilis were reported. Resting eggs collected from low salinity (4 ‰) and higher salinity (about 20 ‰) water bodies did not hatch in both pure water and 50 ‰ salinity incubation but in freshwater And 5 - 40 ‰ salinity hatching solution in different proportion of hatching, of which 5 ‰ salinity in the highest hatchability. The juvenile rotifera hatching from dormant eggs of 20 ‰ salinity in 15 ‰ salinity has a survival rate of more than 90% in 3 to 3 hours at 5-30 ‰ salinity, and can be directly fed without domestication To different salinity nursery ponds. However, the juvenile rotifer hatching from 5 ‰ salinity of dormant eggs at 4 ‰ salinity survived less than 20 minutes in salinity of 25 ‰ and 30 ‰, while dormant eggs at 4 ‰ salinity raised the salinity of hatching solution The young worm hatching in 10 ‰ salinity had a viability of 80% at 30 ‰ salinity within 3 hours. The experiment was mainly carried out indoors, and was successful in the practice of cultivating rotifer in the outdoor soil pond of Zhuangshan Mountain Aquaculture Company in Zhuanghe City. It initially solved the problem of using rotten eggs with low salinity to cultivate rotifers as live bait to 30 ‰ salinity water Feeding problems
