Crawfish crayfish originated in Japan, introduced to China in the 30's, commonly known as "lobster." It is of great significance to implement artificial breeding on it to meet the increasing domestic and foreign demand, and to obtain better economic benefits.
1. Selection of venues: Crawfish crustaceans have strong vitality, can use ponds, rice fields, potholes behind houses, and can also use some “three wastes†water surface, namely, waste water, wasteland, and fishery wasteland. Arable land cultivation.
2. Water treatment: Use 10-15 kg of quick lime per acre to sterilize and disinfect, and pay attention to controlling the relevant water quality indicators in the aquaculture process. The main reason is that the transparency is kept between 20-25 cm.
3, aquatic plants: Krill crawfish Xiyin, it is best to plant in the pond water peanuts and ryegrass and other forage, and on the water to grow appropriate amount of water hyacinth, water peanuts, water spinach, in the water bottom Caress, goldfish Wait. This is conducive to feeding, molting, breeding and other activities of Crawfish crayfish, and reduce their mutual residual food.
4. Feeding of shrimps and shrimps: There are no specialized seedling manufacturers for Crawfish crawfish. There are two ways to solve the problem of seedlings. First, eggs are directly released, followed by juvenile shrimps. Directly to rivers, ditches, ponds, rice fields and other bodies of water directly fishing, or acquired from the market. Generally, 40-60 kilograms of eggs are placed on the mu, or 80-120 kilograms of prawns are placed on the mu, so that the mu yield of shrimp can reach 400-600 kilograms, and the mu effect can reach 1,000 yuan. The brooding brooding is generally put in April and the larvae are usually put in May.
5. Feeding of bait: Crawfish crayfish are omnivorous, and they like to eat plant feedstuffs, such as fresh water grass, water peanuts, water spinach, bran, rice bran or semi-rotated barley, wheat, broad beans, rice and other crop straws. Of course, if some animal feed is available, the growth of the crayfish will be faster, and juvenile shrimp can reach the market specifications within 30-40 days. The crayfish crayfish require higher transparency of the water body, and can put 50-100 tails of flowers and white clams to control the water quality, basically no disease. Usually, every 15-20 days, 10-15 kilograms of lime is used to facilitate the clam shelling.
6. Fishing and listing: Normally, fishing starts in June and July, large-scale listing, and small return to the pond, which can last until the end of October.
