Study on Correlation between Egg Size and Hatching Rate of Procambarus clarkii

In this paper,the correlation between the egg size and hatching rate of Procambarus clarkii was analyzed.The results showed that when the 100-grain egg weight was 0.422 g,the hatching rate was the highest,being 95.1%;when the egg diameter was 1.45 mm,it got the highest hatching rate(94.5%);the egg diameter and egg weight had good correlation.
