The rare drought since the Yangtze River Basin since 1961, allowing the magnificent Dongting Lake to experience a huge change of "vicissitudes of the sea and mulberry fields" in just one month: the water level drops sharply, the water area is decreased, and a large number of ponds appear on the lake bed. Among them, some fish died. How to deal with these wild fish trapped in the pond? On August 25, the local ban and withdrawal office responded that local experts were conducting investigations in cooperation with provincial experts.

When the reporter visited, it was found that many ponds of different sizes appeared along the Dongting Lake embankment. Many fish were trapped in these ponds. Due to the light pond water, the temperature was high, the fish died a lot. Big fish has died. Recently, one of the main tasks of local fishery administrative staff is to inspect these unattended ponds. After discovering dead fish, they will be salvaged in time, and the dead fish will be buried to prevent the water pollution.

The staff of the State Nature Reserve of Dongtong Ting Lake in Hunan said that if the drought continues to develop, the water level of Dongting Lake will not be effectively supplemented, and the death of fish may be intensified.

In this regard, some netizens pointed out that the death of a large number of wild fish in Dongting Lake may bring greater ecological losses and affect the local ecosystem. Seeing that the fish in the pond died in white, some netizens said that why not hurry up to rescue and transfer it to the main lake to retain biological resources as much as possible and reduce losses?

As for whether to transfer these trapped fish, the fishery administration department will make a comprehensive consideration of factors such as feasibility and actual effects.
