What is the one-year-old fish fingerling rearing model in the Guangdong-Guangxi region?

The method of rearing one-year-old fish fingerlings in the Guangdong-Guangxi region differs from that in Jiangsu and Zhejiang. Rather than starting with polyculture of multiple species, monoculture is carried out in the early stage, and after the fish grow to 5-6 cm, polyculture is then carried out according to a ratio. The advantages of this method of rearing one-year-old fish fingerlings in Guangdong and Guangxi are: (1) The survival rate of fish in early-stage monoculture is relatively high, generally 80%-90%. (2) When stocking in proportion in the later stage, "eliminating the inferior and selecting the superior" can be applied. Selecting fish with strong constitutions for polyculture can correspondingly increase the survival rate

(3) The number of summer fry fingerlings used in polyculture in the Guangdong-Guangxi region is far greater than in Jiangsu and Zhejiang.
