Crayfish are native to Central and South America and northeastern Mexico.
Crayfish resembles shrimp and its shell is hard. The depth of the hole is a key factor in determining its degree of harm. China was introduced from Japan in the 1930s and 1940s, and Japan introduced it from the United States earlier. It is mainly used as food, bait, and pets. Crayfish are often mixed in crops (such as rice) in the field. No artificial hatching is required. Once the original species is put in the pond, self-sustaining can be achieved. After the harvest, there is no need to replant the original species. Escaped individuals survived by digging holes in the dam. They can survive in temporary bodies of water, and have a wide range of feeding habits. The establishment of populations is extremely fast and easy to spread. It threatens the local fish, crustaceans, and aquatic plants, destroys the local food chain, and directly destroys the crops (especially aquatic and semi-aquatic crops such as rice) and natural vegetation. It will cause irrigation water loss and field destruction.
In China, we have expanded to Anhui, Hunan, Shanghai, Jiangsu, Hong Kong, and Taiwan to form a large number of natural populations.

Disposable Piercing Guide - WPTC5
A Disposable Laparoscopic Trocar is a medical device used in minimally invasive surgery to create a small incision in the abdominal wall for the insertion of surgical instruments and a camera. It consists of a sharp, pointed tip that is inserted through the skin and into the abdominal cavity, and a sleeve that provides a pathway for the surgical instruments. Once the trocar is inserted, the sleeve is locked in place and the instruments can be inserted and removed through it. Disposable laparoscopic trocars are designed for single-use only to prevent the risk of infection and cross-contamination. They are available in different sizes and shapes to accommodate various surgical procedures.
