There will be more shrimps in reservoirs, rivers, lakes and other waters in September. Shrimp likes to live in fresh water or brackish water, usually reservoirs, rivers, lakes and so on. In the autumn of September, with the gradual decrease of air temperature and water temperature, river shrimps will gradually migrate to the waters with higher water temperature, resulting in an increase in the number of river shrimps in these waters. Therefore, in September, shrimp will appear more in reservoirs, rivers, lakes and other waters.
