According to the results of 851 samples collected from 1994 to 1998, the results showed that the ovarian maturity of the coastal shrimp in northern Shandong Province was divided into three groups based on the observation of external morphology, biomicroscopy, egg structure analysis, egg diameter measurement and maturity coefficient Ⅰ ~ Ⅵ period. Gonadal maturity once during the year, and there are four stages of formation, proliferation, maturation and rest. The spawning period is from June to August, and the peak period is from early July to mid August. The age of sexual maturity is 1 year old, the sex ratio is 5 3.5 0:46. 5 0, and the individual fertility is 1 73.1 0-531 895.000 , Unit ovary fertility 2 844100 / g.
