【Explanation】Recently, the largest inland freshwater lake in China, Bosten Lake, has a large estuary of 40,000 national level protected aquatic wild animals. Local fishery administration staff participate in the fry release work together with the public and volunteers. Each flatfish has its own "identity card", which can be tracked and monitored by scanning.

　　From the ecological monitoring process of Bo Lake in 2017, we found that our flatfish has a certain natural group in Bo Lake. From 2017 to the present, there have been more than 20 tail fishes in all return fishing. The fish we have marked shows that the growth of the fish we have marked in these years is very good.

　　[Explanation] It is understood that this year, Bohu County, Xinjiang plans to increase the release of more than 2 million fish stocks such as grass carp, silver carp and bighead carp. Currently, the number of fish species has increased to 32, effectively promoting the sustainable development of fisheries in the region.
