The pond mainly raises yellow bone fish, with a size of about 3,000 to 4,500 fish weighing 20 grams to 50 grams per tail per mu, and about 200 silver carp per mu (size 7 cm to 9 cm). The stocking quantity of yellow bone fish in the mixed culture pond is generally 300 to 500 per mu (size 4 cm to 5 cm). The stocking quantity can be appropriately increased according to the stocking situation of other fish and the level of aquaculture technology. Insist on patrolling the pond three times in the morning, noon and evening, carefully observe the activities, feeding and growth of fish, and deal with problems in time; frequently inject new water to prevent water quality deterioration, and also prevent fish from getting sick and floating. It is best to inject 20 cm to 30 cm of new water every 10 days, and turn on the aerator on rainy days. Apply quicklime once every half a month, and the amount used each time is 15 kg to 25 kg per mu. |
