Recently, the news of a large number of wild tarpon in some areas of the Yangtze River has attracted widespread attention. On the one hand, this phenomenon is regarded as a positive signal of water quality improvement and ecological restoration of the Yangtze River, but on the other hand, it has also aroused people's attention to the situation of other fish, especially anchovies. In this context, we have to think: why is there a large number of wild tarp in the Yangtze River, but the survival of anchovy is worrying?
First of all, the phenomenon of a large number of wild tarpon in some areas of the Yangtze River is closely related to water quality improvement and ecological restoration. For a long time, the Yangtze River basin has faced serious water pollution problems, which has seriously affected the living environment of many fish. However, in recent years, the Chinese government has taken a series of measures to control water pollution in the Yangtze River, including strengthening sewage treatment and limiting industrial discharges. The implementation of these measures has improved the water quality of the Yangtze River to a certain extent, providing a better living environment for wild silver carp and other fish.
Secondly, the large number of wild tarpons is also related to human activities. Silver carp is a highly adaptable and fecundious fish with fast growth, strong reproductive ability and wide adaptability. This allows silver carp to survive and reproduce under different environmental conditions. Human activities, such as the development of aquaculture and the release of fry, also provide favorable conditions for the reproduction of silver carp. Therefore, the phenomenon of a large number of wild tarpons in some areas of the Yangtze River is also the result of human activities.
However, compared with the flourishing of wild silver carp, the survival of anchovy is worrying. Anchovy is one of the important economic fish in the Yangtze River basin and one of China's specialties. However, due to factors such as overfishing, water pollution and habitat destruction, the number of anchovies is gradually decreasing, and the survival situation is becoming more and more serious. Especially during the construction and operation of the Three Gorges Reservoir of the Yangtze River, the living environment of anchovy has been seriously damaged. The existence of these problems makes the survival of anchovies worrying, requiring measures to protect and restore their populations.
In summary, the phenomenon of a large number of wild tarpon in some areas of the Yangtze River is a positive signal for the improvement of water quality and ecological restoration of the Yangtze River on the one hand, and is closely related to human activities on the other hand. However, compared with the flourishing of wild silver carp, the survival of anchovy is worrying. In order to protect and restore the ecological environment of the Yangtze River, we need to strengthen water pollution control, limit overfishing and habitat destruction and other measures to protect and restore the stocks of important fish such as anchovies, and achieve sustainable development and ecological protection in the Yangtze River Basin.
