Why can't Xuzhou Dalonghu fish?

Protect the ecological environment. Xuzhou Dalong Lake is an artificial lake in Xuzhou City, which provides a beautiful leisure and entertainment place for urban residents and is no longer open to fishing. The specific reason is that in order to protect the ecological environment and prevent the occurrence of public health problems, the relevant departments prohibit fishing and other activities in the lake to ensure the safety and stability of the lake water quality and ecosystem, as well as the health and safety of citizens.
