Lobster mainly eats at night, so the amount of feed fed at night accounts for 70-80% of the whole day's bait. The bait should be put in the shallow water beside the pool. The well can be fixed at a fixed time, fixed point and fixed quantity. Each pond can set up 2-4 bait observation tables to observe whether the bait is finished every morning to determine the amount of feed on the day. Too little feeding will inhibit the growth of lobsters or kill each other because of hunger. Too much will not only increase the cost but also worsen the pond environment, which is disadvantageous to the growth and molting of lobster. General shrimp bait or lobster special bait can be used. The daily feeding amount should be full, finished, and no residual bait should be left. Generally, the shrimp is 20-25% of the body weight, 15-20% of the body weight, and the prawn is 10-15% of the body weight, twice a day, once in the morning and once in the evening.
