1, pond cleaning, the aquaculture pond in metapenaeus ensis should have good water quality and convenient drainage, and 2 to 10 mu is the most suitable, and the water depth is between 1.2 and 1.5 meters, and the inlet and outlet water should be filtered by screen silk to prevent harmful organisms from invading the shrimp pond and hurting metapenaeus ensis.

2. Fertilize and cultivate bait, filter with a 60-to 80-mesh sieve one week before stocking, and inject 30 cm of water. Apply 50 kg of fermented animal manure or 5 kg of urea per mu of cultivated bait, or put the organic fertilizer in a woven bag and push it to the bottom of the pond.

3. Shrimp fry are stocked when the water temperature 18 to 20 degrees in late May. However, the shrimp fry should be desalinated for more than one week, and 30,000 to 40,000 shrimps with a density of 0.7 to 1.0 cm should be put in an acre, and the shrimps below 0.7 cm should be temporarily raised.

4, feeding bait, shrimp seedlings in the next pond 1 month without feeding bait, 1 month after feeding compound bait, and with fresh fish, shellfish, etc., feeding amount is 3% to 5% of body weight, 2 to 3 times a day, 1/3 in the daytime, 2/3 in the evening, and the feeding amount should be appropriately increased from July to September.

5. Adjust water for disease prevention. After the shrimp fry are stocked for 10 days, add 10 to 15cm every week, change the water for 20 to 30cm every 2 to 3 days in high temperature season, and sprinkle with 5 to10kg quicklime slurry every half a month.15 to 20.

6, timely harvesting, harvesting time mainly depends on the growth of shrimp and market demand, freshwater ponds can grow to 7 to 10 cm long after 80 to 100 days, which can be carried out by rotation.
