First, the pond conditions Since the breeding of fresh shrimp species generally can be cultivated about 2 cm per acre seedlings 3 million -400 million, farmers can determine the area according to the demand, choose 1-3 acres of ponds, pond sludge requirements less than 15 cm The depth of the pool is 1.5 meters. The pond water supply and drainage system is perfect. The water source conditions are good and the water quality is pollution-free.
Second, the preparation
1. Clear pond thoroughly. Breeding is usually done at the end of May, so the ponds should be disinfected by the end of April and early May. The pool water will be discharged to 10-20 cm, and the quicklime will be used to clear the pond. The amount of water per acre is 150-200 kg and it is required to splash evenly.
2. Planting aquatic plants. After 7-10 days of clear ponds, the best way to transplant plants is to use black algae. The grasses are easy to survive and grow faster, and the formation of litchi is convenient for the hatched shrimps to inhabit. In order to make aquatic plants grow faster, organic fertilizers can be applied in small amounts. After the aquatic animals are in groups, they can put eggs in shrimp.
3. Disinfect the insecticide before it is released. The insecticide treatment should be carried out in front of the shrimps in the pond before launching the eggs, and the insecticides such as fish killers and other shrimps can be used to kill large cladocera, water spiders, etc. Insects, while adding pool water to 50-60 cm.
3. After releasing the egg-holding shrimps to the pool, the egg-feeding shrimps should be placed 8-10 kg per mu. In order to facilitate the observation of the development of fertilized eggs, 1-2 m2 cages can be set up in the corner of the pond for 3-4. Each cage is placed around 50 eggs, and the color change of the fertilized eggs is observed every day. When the fertilized eggs become When purple spots appear, ripening organic fertilizer should be piled up in the corners of the pond. Chicken, duck, and cow dung should be used to cultivate the palatine feed in the pond so that the larvae that break the membrane can obtain open bait. The egg-bearing shrimp should be fed with 1-2 kilograms of chopped small trash fish daily during the pool.
Fourth, daily management
1. Feeding. After the fertilized eggs of the egg-feeding shrimps are released from the film, the soybean milk is fed into the pond, and 1 kilogram of soya bean is ground into the soybean milk per acre per day, and the water conditions and the weather of the pond are added and subtracted as appropriate. 2. management. During the larva rearing period, probiotics such as EM progenitors and photosynthetic bacteria should be applied once a week to improve water quality and supplement palatability feeds. Lime was applied every 10 days to regulate water quality and supplement calcium source. The dosage was 15 kg per mu of water at 1 meter and the pH of the pool water was between 7-8.
3. Water quality is monitored daily. Daily measurement of dissolved oxygen, pH value, ammonia nitrogen, nitrite, etc. is performed according to the measurement conditions.
4. Add new water in a timely manner. In the development of shrimp breeding, it is necessary to effectively shut down the water. The water inlet and outlet shall be filtered with a 60-mesh gauze to prevent wild fish or fish eggs and other aquatic animals from flowing into the pool. During the cultivation of the shrimp, fresh water is added every 4-5 days and the water injection volume is 10-15 cm.
5. When the seedlings grow to about 1 cm, they can be changed to artificially mixed powders. The main ingredients are wheat bran, fish meal, and sub-powder. During the cultivation period, attention should be paid to the growth of the pond grasses, and if it is too dense, it should be removed to avoid competing for nutrients.
V. Fishing and transportation Generally, shrimps can grow up to 2 centimeters after they are released from egg-holding shrimps. After 30-40 days, young prawns can be considered as commercial shrimp breeding seeds. Pull the net to use the summer flower net, you should remove the water in the pond before fishing to pull the net operation. Such as short-distance transport available live barrel oxygenation transport, depending on the length of the transport distance per barrel, can be installed within 300 hours 300,000 -400,000, when transported in the container can be appropriate to lay some plants, can improve the survival rate of transport.
