Experience of culturing mandarin fish in adult fish ponds
First, pond conditions. The area of adult fish ponds with feeding fish in the lower layer is generally 5-10 mu, and the pond with filter-feeding fish in the upper layer is generally 10-20 mu with a water depth of 2-3 meters, with less silt and perfect water intake and drainage system and equipment.
Second, the release of fish species. Generally, there are 40-50 mandarin fish with a body length of 3.3-4.5 cm, and the release time is in mid-late May and no later than early June at the latest.
Third, the source of bait fish. When the adult fish pond enters and drains, there are often a certain number of wild miscellaneous fish entering the pond. These wild miscellaneous fish, as well as the self-propagated seedlings of carp and crucian carp in the pond, can become good bait for mandarin fish; another source of bait fish is to replenish a certain number of summer flower fish species in adult fish ponds, the number of which is generally 1000 per mu.
Fourth, pond management. The management of mandarin fish culture is mainly in two aspects: one is water quality management. in ponds dominated by feeding fish, flushing is generally added once every half month, with a depth of 20-30 cm each time, and once a week during the high temperature period from July to September; ponds with filter-feeding fish should be flushed frequently, and one 1.5-2 kilowatt aerator should be equipped with every 6-8 mu of water surface. At the same time, quicklime water should be sprinkled once a day, with 15-20 kg of quicklime per mu each time. On the other hand, patrol the pond, every morning before sunrise must patrol the pond to observe whether mandarin fish floating head, in addition, but also often check the situation of bait fish, timely supplement bait fish.

Measures for increasing production and increasing efficiency of mandarin fish
Mandarin fish monoculture needs to be matched with sufficient bait fish, and the technical requirements are high, so it is difficult to cultivate mandarin fish in large areas. Mandarin fish can be cultured in other aquaculture waters. First, the way of captive culture. 1. Captive culture in adult fish ponds. Ponds that raise food-eating fish require plenty of water
