1. Pond treatment: The pond should be hard at the bottom, with little silt, close to the water source, and 0.7PPM mixture of copper sulfate and ferrous sulfate should be sprinkled about 0-2 days before seedling release. 2. Stocking: Before releasing the fish, soak and clean the fish with 3PPM copper sulfate solution or 3% salt solution for about 5- 10 minutes. If it is a 3cm long mandarin fish (mandarin fish), it is 2000 fish/mu. Stocking 6-8cm mandarin fish, with 1000- 1200 fish per mu. If the annual mandarin fish species are stocked, 500 mandarin fish will be stocked per mu, and the stocked flowers, silver carp and laokou crucian carp will be matched at the same time.

I. Pond treatment

1. The pond used for aquaculture requires a hard bottom, less silt, close to the water source and good drainage and irrigation conditions. If there is no bait fish pond, the culture area should not be too large, 1-3 mu; if there is bait fish pond, the culture area should be 2-5 mu.

2. After entering the water, spray the whole pond with a mixture of 0.7PPM copper sulfate and ferrous sulfate (5: 2) about 1-2 days before stocking the seeds.

Second, stocking

1. Before stocking, soak and disinfect the fingerlings with 3PPM copper sulfate solution, 3% salt solution or 20PPM potassium permanganate solution for about 5- 10 minutes.

2. If 3cm long mandarin fish (mandarin fish) are directly stocked, generally about 2,000 are stocked in each acre of pond. In the case of stocking 6-8cm mandarin fish, about 1000- 1200 fish are generally stocked in each acre of pond. If annual Siniperca chuatsi fingerlings (50-100g/fish) are stocked, generally about 500 fingerlings are stocked per mu of pond, plus 200 flowers, silver carp and 200 old-mouth crucian carp.

Third, feeding

1, generally choose shad, crucian carp, silver carp and bream fry as bait fish for Siniperca chuatsi.

2. For Siniperca chuatsi with a body length of 3- 14cm, 1.5-5cm is suitable as bait fish. The body length of Siniperca chuatsi 15-20cm, that of bait fish is 3-6.5cm, that of Siniperca chuatsi is 2 1-25cm, and that of bait fish is 4.7-7.5cm. For Siniperca chuatsi with a body length of 26-30cm, the body length of bait fish should be 6-9cm. For Siniperca chuatsi with a body length of 3 1-35cm, 7.5- 15cm is suitable as bait fish.

3. If 3cm of Siniperca chuatsi fingerlings are stocked, the feed amount will gradually decrease from 70% of the body weight to 8- 10%. If the first-year-old Siniperca chuatsi fingerlings are stocked, the feeding amount will be gradually reduced from 8% to 5% of the body weight, especially during the period from beginning of autumn to Bailu, it is necessary to ensure sufficient bait fish.

4. Feed once every 5-7 days in the middle period (July-September) and once every 7- 10 days in the early and late period.

Fourth, management.

During the period of 1 and July-September, fresh water should be replaced every 7- 10 days to ensure the transparency of the pool water is about 30-40cm.

2. Ensure that the dissolved oxygen in the water is above 4-5mg/L. ..

During the period of March, June and September, quicklime is sprinkled every 10 day, and the dosage per mu of pond is about 15kg, and the ph value of pond water is controlled between 7 and 8.5.

4. In case of muggy weather or thunderstorm, turn on the aerator for aeration in time.

5. Check the pond regularly to observe the eating and activities of mandarin fish.
