Crayfish in the pond can be directly fed with minced fish, snail meat, silkworm chrysalis, earthworms, leftovers from slaughterhouses, rice bran, bean cakes, bran, pumpkin, sweet potatoes, fresh aquatic plants, etc., or with shrimp compound feed, but the crude protein content of the feed should be kept above 25%. Scientific feeding: crayfish are omnivorous. It likes to eat fresh animal bait such as miscellaneous fish, and plant bait such as soybean, bean cake, corn and fresh aquatic plants. It can also be fed with feed. Under the condition of ensuring the quality, the daily feeding amount is generally based on eating and eating until no residual bait is left, and feeding is twice a day, morning and evening 1 time. Because crayfish mainly eat at night, the amount of bait thrown at night accounts for 70%~80% of the whole day's bait, and the bait should be thrown in the shallow water near the pool.

From July to 10, the water temperature is suitable, which is the growth season of shrimp. At this time, the daily feeding amount is based on the satiety of shrimp, and no residual bait is left after eating. General animal feed accounts for 12% of shrimp weight, and dry feed or compound feed accounts for 35%~5% of shrimp weight. Feed is put in the shallow water near the pool, and fed twice a day, 1 time in the morning and 60%~70% in the evening. In other seasons, feed it 1 time every day, and feed it after sunset, and the daily feeding amount is 2%~5% of the shrimp weight. Crayfish have poor swimming ability, small range of activities, and the habit of occupying land, so it is necessary to adhere to timing, fixed point, qualitative and quantitative feeding. In addition, feed feeding should pay attention to sunny days, sultry, continuous rainy days or when the water quality is too strong; A large number of shrimps throw less when molting, and more after molting.

Lobster culture refers to the cultivation of lobsters for profit, and shrimp habitats, such as gravel, bricks, stones, nets [1], old tires, grass dragons, etc., are set up in the culture waters. As a nest for shrimps, they can hide and defend against enemies.
