Abstract:during the reproductive behavioral ecology, its reproductive behavior such as the first time of sexual maturity, mating system, mating behavior, reproduction season, hole behavior and care of young features was studied in this paper. In the main breeding season of original crayfish, such as shrimp mating and spawning of the field natural acquisition samples are into experimental observation statistics, the number of every batch collection shrimp samples is more than 30, body mass ranged between 15 g and 40 g. Our results show that: 1) With fast growth and early sexual maturity, the individual can reach sexual maturity after 612 months. 2) It spawn generally in autumn and winter, but its mating and breeding period are extensive; mating behavior can be ob the mating rate was 20% and the egg laying was zero in July (12.56 g); the mating rate was 45% and the egg laying was 5% in August (1the results of experiments showed that Aug., Sept., and Oct. are its mostly mating seasons, and Oct., Nov. and Dec. are its spawning fastigium. 3) there was sexual in mating system, male and female sex ratio showed loosely, and repeated mating generally. 4) it showed a hole tendency obviously. Burrowing feature is one of the most significant outstanding habits in . It seems as a survival and reproductive strategy on adaption, mating, spawning, hatching, care and so on. Holing behavior in different season indicates different biological function. The aim of this study is to supply theoretical basis for its artificial breeding and breeding production.
