Abstract:

The artificial breeding technologies of Cherax quadricarinatus are not mature and have not been widely promoted. The market demand is far from being satisfied by the semi-natural breeding technology of C. quadricarinatus. As a result, the development of C. quadricarinatus market is slow, which greatly restricts the rapid and high-quality development of C. quadricarinatus industry. This paper reviewed the biological characteristics of C. quadricarinatus, the internal and external factors affecting its reproduction and incubation mode, and discussed the possibility of C. quadricarinatus egg-carrying in different seasons and at different times in the future. The study could provide reference for improving ovigerous rate, egg laying amount and hatching rate of C. quadricarinatus, and support the large-scale and industrialized breeding of C. quadricarinatus.

Key words: Cherax quadricarinatus, artificial breeding, biological characteristics, incubation mode
