Crayfish are often mixed with crops (such as rice). No need for artificial incubation. Once the original seed is put into the pond, it can achieve self-maintenance. After harvesting, there is no need to put the original seed again. Those who escaped dug holes in the dam to survive. They can survive in temporary water bodies, have a wide range of feeding habits, establish populations very quickly and spread easily.
Extremely threatening local fish, crustaceans and aquatic plants and destroying the local food chain; Because it feeds on roots, it directly damages crops (especially aquatic and semi-aquatic crops such as rice) and natural vegetation; Cave construction leads to the loss of irrigation water and the destruction of fields; Because of the miscellaneous eating habits of crayfish, it has certain influence on the development of fry and the cultivation of 1 year-old fish, and it is harmful to the artificially cultured young mussels.
Crayfish often cut crops, especially rice crops, because of its strong adaptability, strong resistance, wide feeding habits and rapid population proliferation, and may compete with local crayfish varieties.
habitat
Habitat in permanent streams and swamps, temporary habitats, including ditches and ponds. They are usually mixed with plants or sawdust in streams, which will destroy and weaken banks. They can be found in simple caves in areas where floods recede. Living in wetlands, lakes and rivers with shallow water bodies and abundant aquatic plants.
This species is distributed in many habitat types, including wetland meadows, underground karst systems, seasonal swamps and wetlands, permanent lakes and rivers, paddy fields, irrigation channels and reservoirs. This species can tolerate a range of environmental conditions, including low oxygen levels and high temperatures.
