Adult fish breeding freshwater Bai Shao can either be cultivated in ponds or cultured in cages.
Pond aquaculture includes main pond cultivation, fish stock pool cultivation, and polyculture of adult fish ponds. According to the experience of the Hebei Province Freshwater Integrated Aquaculture Pilot Farm, in early October (water temperature 17°C), oyster fingerlings (125 g / tail, density of 1/15 hectare) were placed and matched with squid and squid. Species (with specifications Jianou, the density of 200 per 1/15 hectare; the ratio of dragonflies and dragonflies is 3:1), raised to the middle of June the following year out of the pond. After the pond was disinfected, 15 g/tail freshwater whitefish were stocked in late June, and 1200 fishes were distributed per l/15 ha. At the same time, 20 tails of tilapia (200 g/tail), 160 tails of carp and squid were used, and the proportion of earthworms and earthworms was used. 4:1. By the end of the breeding period on September 20, two trouts will be farmed each year. The average annual output will reach 1,554 kg per 1/15 hectare, and the input-output ratio will be 1:2.46. The benefits will be significant.
Freshwater white cut teeth will snap off the synthetic fiber mesh. Therefore, net cages should be used for freshwater whitefish breeding. Feeding and management methods are the same as carp and tilapia, and they should be sold out of the box or transferred to the greenhouse in October to be frozen.
