1. How to farm crayfish in fields

When farming crayfish in fields, pay attention to water quality and water source, and never raise them with unclean water. Before releasing the shrimp fry, appropriate disinfection treatment can be carried out to ensure a good subsequent survival rate. Do not apply and expose pesticides during the crayfish molting period, so as to avoid losses to the crayfish.

2. Points to note

1. Crayfish are very sensitive to pesticides. Pesticides such as trichlorfon and decamethrin are prohibited, and it is also necessary to prevent large amounts of farmland pesticide water from flowing into the shrimp pond. To avoid unnecessary losses, plant aquatic plants around the inside of the pond, generally covering one third of the pond water surface, to facilitate the crayfish's hiding and to produce organisms that crayfish like.

2. Even though crayfish are tenacious in life and resistant to low oxygen, excellent water quality is still a key component of high crayfish yields. Under low-oxygen conditions, crayfish are unwilling to eat and their growth decreases, and they are prone to escaping and developing diseases. As soon as crayfish are found coming ashore in groups, immediately adjust the water quality.
