2. To raise crayfish, you can use plastic pots, sorting boxes, acrylic or glass fish tanks. Note that the height of the container should not be lower than the body length of crayfish to prevent it from escaping.
3. If you have a filtration system, you can arrange to simulate the natural environment, using tree roots, bamboo tubes, etc. It is placed for climbing and planted with plants such as Eichhornia crassipes and Haematococcus verticillata for shelter, habitat and foraging. The water depth is 0.5 meters. If there is no filtration system, it is recommended to raise it in a bare tank and put a small amount of plants. The water depth should be 3~5 cm. Change the water in time when the water quality becomes worse.
4. Too high stocking density of crayfish is easy to cause hypoxia, fighting and disability. Therefore, the family develops annual crayfish, with a maximum of one per square decimeter. At the same time, too many males can easily lead to fights, so the ratio of male to female is 3: 1.
5. Crayfish is omnivorous. It likes to eat fresh animal bait such as miscellaneous fish, and plant bait such as soybean, bean cake, corn, fruit and fresh aquatic plants. Family rearing can feed fish, snails, shrimps, watermelons and steamed bread. Under the condition of ensuring the quality, the daily feeding amount is generally based on eating, eating and leaving no residual bait. From July to 10, the water temperature is suitable, which is the growth season of shrimp, and it is fed twice a day, 1 time each morning and evening. Feed 1 time every day in other seasons. Because crayfish mainly eat at night, the feeding amount at night accounts for 70%~80% of the whole day's bait. Cast more when the weather is sunny, and cast less when it is hot, stuffy, rainy or the water quality is too strong; A large number of shrimps throw less when molting, and more after molting.
