摘      要：In laboratory conditions,effects of rearing temperature and stocking density were examined on hatching of fertilized egg and growth of auricularia larvae of Apostichopus japonicus *** series like larval length and density,metamorphic time,and survival rate of the larvae were *** showed that for ***,survival rate(from fertilized egg to late auricularia) decreased significantly with the increasing rearing temperature(P26℃).Hatching rate was significantly different between 0.2-5 ind./ml groups and 20-50 ind./ml *** larvae at the higher density had the smaller maximal-length,whereas needed longer time to complete *** study suggested that 21℃ and 0.4 ind./ml can be used as the most suitable rearing temperature and stocking density for large-scale artificial breeding of *** s larvae.
