June, July and August. Although crayfish can be eaten all year round, the best tasting season is from May to 10. During this period, crayfish has the most full meat and the most delicious taste. Therefore, if you want to taste the most delicious crayfish, you'd better choose June or July or August. It should be noted that crayfish in different regions have different seasonality. For example, in southern regions such as Guangdong and Guangxi, crayfish may be put on the market earlier because of the warmer climate. In the northern region, the growth rate of crayfish is slow due to the low temperature, so the time to market may be delayed.
