Crayfish

Crayfish is a lobster-like crustacean that lives in freshwater. The Northeast is called cricket. Crayfish is the most widely distributed invasive alien species among crustaceans. Due to its omnivorous nature, fast growth rate, and strong adaptability, Crayfish has an absolute competitive advantage in the local ecological environment. Its feeding range includes aquatic plants, algae, aquatic insects, animal carcasses, etc., and can kill each other when food is scarce.

Crayfish have become an important economic aquaculture species in China in recent years. Escape should be strictly prevented in the process of commercial farming, especially escape into inaccessible original ecological water bodies. The destructive harm caused by the ecological competitive advantage of local species has been widely reported all over the world and should be paid great attention.

Season: April-November
