Sihai net: Da's fish, commonly known as shad, is the largest freshwater fish. The species originated in the Cretaceous period 130 million years ago. It once lived with dinosaurs on the earth. Its primitive and simple shape has hardly changed for more than 100 million years. It is an endangered wild protected animal and a precious fish only in the Heilongjiang Basin in the world. It is called a living fossil by biologists and has precious scientific research value.

At present, it is the spring fishing season in Heilongjiang and Wusuli rivers. On the afternoon of the 27th, the border police station along the river of Jiamusi border management detachment of Heilongjiang entry-exit border inspection station received a feedback from the police of the Beach police office that a fisherman mistakenly caught a Da Shi, which is called a living fossil, 72km away from Heilongjiang.

The police of the border police station along the river arrived at the scene and found that there was a wound in the tail of the Da Shi, so they quickly contacted the fishery department. According to the identification of technicians, this dachshund is a female. Because it has been hurt during the fishing process, it needs to be sent to Fuyuan sturgeon releasing station for treatment. The police and technicians jointly delivered the Da's house to the release station.

According to the measurement, the tail of Da Shi weighs 88 kg, female, over 20 years old, with wounds on the back and tail, but at present, the vital signs are stable and there is no life danger.

According to the inspection of technicians, this dachshund has fish eggs. At present, it is being treated by professionals in the release station. When it lays eggs and recovers and meets the release conditions, the professionals will release it and the fry at a suitable place.
