What are the natural enemies of crayfish?

Crayfish have many natural enemies, including birds in the sky, mice underground, fish in the water, etc.

Birds and mice are common natural enemies. During the peak period of crayfish breeding, especially when the crayfish float to the surface due to lack of oxygen, it is definitely a feast for birds. In autumn and winter, food on land is no longer readily available, but crayfish, which seem inviolable with large scissors, are easy to get and much more delicious. Especially at night, when crayfish come ashore, it is even more of a feast.

The natural enemies of crayfish in autumn and winter are mainly birds and mice. These two natural enemies pose a great threat to crayfish. The daily amount may seem small, but accumulated over time, it is not a small number. You can often find a large number of crayfish shells in the grass.

The life habits of crayfish

Crayfish like to grow in wetlands, ponds, and streams with abundant aquatic plants. As long as there is enough food, they can grow well. Crayfish have a strong ability to adapt to the environment. They can survive in both sewage and clear stream water. They are also very adaptable to the environmental temperature. They are extremely cold-resistant and heat-resistant. They can survive in an environment of -14℃ to 40℃, and can grow and develop normally in an environment of 10℃-30℃.

Crayfish are omnivores. In terms of eating habits, they prefer to eat mud at the bottom of the river, and like to eat dead small fish or other aquatic organisms. They mainly eat plants, small fish, shrimp, plankton, benthic organisms, and algae. Since most crayfish are very resistant to pollution, they can still survive in water containing high levels of pollutants.
