Abstract：The aim of this experiment is to explore the artificial breeding technology of Cherax quadricarinatus suitable for Tianjin area.In October 2021,Cherax quadricarinatus were introduced from Jiangsu to be cultured in a factory workshop,and the parent lobsters were sexually mature in succession after five months.At the end of February of the following year,sexually mature lobster pairs were selected and placed in the hatching tank,and then mated and laid eggs successively.The egg carrying peak was reached in mid-April,the egg carrying rate was 45.65％,and the average egg carrying capacity was 805 eggs/tail.Under the conditions of water temperature 26-28 ℃,dissolved oxygen above 5 mg/L and daily light for more than 14 h,the fertilized eggs broke membrane after 40 to 45 days.The hatching rate was 88.7％,and a total of 167 155 larvae were produced.The average survival rate was 68.1％,and the survival rate gradually increased with the increase of month.The results show that factory breeding of Cherax quadricarinatus has the characteristics of high egg carrying rate and high egg carrying capacity.In the future,the transport and breeding facilities of juvenile lobster can be further optimized to improve the level of factory breeding of Cherax quadricarinatus in Tianjin area.
