1, the pond is cleaned, and the water quality of the culture pond of Neopenaeus monodon is good, and the drainage should be convenient. The most suitable area is 2 to 10 mu, and the water depth is 1.2 to1.5 m. The inlet and outlet water should be filtered by screen wires to prevent harmful organisms from invading the shrimp pond and injuring the Neopenaeus monodon.
2. Fertilize the culture bait, filter it with a 60-80 mesh sieve one week before stocking, and inject 30 cm of water. Apply 50 kilograms of fermented animal manure or 5 kilograms of urea per mu of culture bait, or put organic fertilizer into woven bags and push it to the bottom of the pool.
3. Shrimp stocking: When the water temperature 18 to 20 degrees in late May, but the shrimp seedlings need to be desalinated for more than one week, 30,000 to 40,000 shrimp seedlings with a density of 0.7 to 1.0 cm per mu will be temporarily raised.
4. Feeding bait: shrimp fry need not be fed bait in Xiatang 1 month, but should be fed compound bait after 1 month, and the compound bait is 3% ~ 5% of their weight, 2 ~ 3 times a day, during the day 1/3, at 2/3 in the evening, and the feeding amount should be appropriately increased from July to September.
5. Adjust water and prevent diseases. After 65,438+00 days, add 65,438+00 ~ 65,438+05 cm of water every week, change 20 ~ 30cm of water every 2 ~ 3 days in high temperature season, sprinkle 5 ~ 65,438+00 kg of quicklime slurry every half month and mix for 65 days every 65,438+05 ~ 20 days.
6. Timely harvesting. The harvesting time mainly depends on the growth of shrimp and market demand. After 80- 100 days, the freshwater pond can grow to 7- 100 cm long, which can be carried out alternately.
