In general, secondary species are transferred to the same culture material for expanded culture to become productive species. Secondary species are generally packed in 750 ml mushroom bottles or plastic bags. (1) Formula 1 of culture material: 90% of rice straw, 9% of wheat bran (rice bran) and 1% of gypsum powder. The preparation method is to select golden, mildew-free dried straw, cut it into 3 centimeters long, soak in water for about 12 hours, and make it.

Fish species are released in autumn to ensure survival in autumn.
Strengthening the cultivation of fish species in autumn is the key to improve the survival rate of overwintering fish species. Improve the environment before the release of fish species, release half of the original pond water, and then add new water. 150 kg fermented manure was applied per mu pond, once every 9 days, for a total of 3-5 times. Appropriate topdressing of chemical fertilizers based on nitrogen and phosphorus, generally 1.5-2.5 kg of urea and 3-5 kg of superphosphate per mu of pond, about once every 7 days. Add fresh water after each fertilization to keep the transparency of the pool water at 20-30 cm. Use quicklime 10 per mu of water every half a month
