Last Updated: 2024/11/22, The way of cultivating one-year-old fish species in Guangdong and Guangdong is different from that in Jiangsu and Zhejiang. Instead of multi-species mixed culture at the beginning, monoculture was carried out in the early stage, and after the fish grew to 5-6 cm, mixed culture was carried out in proportion. The advantages of this way of cultivating one-year-old fish species in Liangguang are as follows: (1) the survival rate of fish cultured alone in the early stage is relatively high, usually 80% to 90%. (2) in the later stage, we can "get rid of the inferior and take the best" when matching and stocking in proportion. Mixed culture of strong fish can also improve the survival rate accordingly.

The way of breeding one-year-old fish species in Guangdong and Guangxi is different from that in Jiangsu and Zhejiang. Instead of polyculture at the beginning, it is monoculture at the early stage, and after the fish grows to 5~6 cm, it is polycultured according to the proportion.

The advantages of this way of breeding one-year-old fish species in Guangdong and Guangxi are as follows:

(1) The survival rate of single-cultured fish in the early stage is relatively high, generally between 80% and 90%.

(2) In the later stage, when the proportion is matched and stocked, it can be "to eliminate the inferior and select the superior". Taking strong fish for polyculture can also improve the survival rate accordingly.

(3) The number of summer flower fish species polycultured in Guangdong and Guangxi is much more than that in Jiangsu and Zhejiang.
