Yangzhou: tens of thousands of "environmentally friendly fish" are released to Shaobo Lake

Yesterday, fishing sails were dotted on Shaobo Lake. The Gaobao Shaobo Lake Management Committee released 10 million tail silver carp and 200000 mandarin fish into the lake.

Watching Xiaoyuer jumping into the water, Wang Youpeng, a fisherman from Daqiao Village, Gaoyou City, smiled and said, "releasing is a good thing. Not only has the lake become clear, but our fishermen's income has also been guaranteed!" This year, I caught more than 20 jin of silver carp in the lake. "

Despite the fact that fish fry is very small, but very expensive, one mandarin fish fry costs 1.20 yuan, and 200000 fish fry are invested at once, which costs hundreds of thousands of yuan. It belongs to high value-added high-quality fish, adult fish sold for dozens of yuan a jin! Silver carp is a kind of "environmental protection fish", which mainly feeds on phytoplankton in the water. 1 kg of silver carp needs about 8 kg of algae (dry matter), which reduces the load of nitrogen and phosphorus in the water to a great extent and enhances the self-purification ability of lake ecology.

According to reports, Gaobao Shaobo Lake is the third largest freshwater lake in our province, and a total of 1.6 million yuan of fish fry will be released this year, the highest in history. Although the lake is rich in fishery resources, it does not increase the fishing output, and the annual fishery output is about 40 million yuan, implementing "zero growth". This not only maintains the population balance, but also improves the purification capacity of the lake, and maintains the second-class water quality for a long time.
