As the 30,000 Xinjiang bighead fry injected with electronic tags in their bodies were released in Bosten Lake, Xinjiang’s 2010 aquatic organisms multiplied and released activities in Xinjiang Ulungu Lake, Ili Chaqi Reservoir, Sailim Lake, and Kizil Six locations including the Reservoir and Dongfanghong Reservoir in Kashgar were carried out at the same time. Nearly 79 million Xinjiang bighead fish and economic fish fry were released. This is the first time that Xinjiang has carried out electronic signs and scientific research activities such as tracking and monitoring of large-headed fish, a national first-class aquatic wildlife protected exclusively in Xinjiang.

Niu Dun, Vice Minister of the Ministry of Agriculture, and Qian Zhi, Vice Chairman of the Autonomous Region, participated in the event and put the first fry into Lake Bosten.
Qian Zhi said that Xinjiang is rich and unique in aquatic resources, and the autonomous region attaches great importance to aquatic biological resources and ecological environmental protection, and increases the activities of multiplication and release year by year. It is hoped that fishery departments and agriculture-related departments at all levels will unremittingly carry out multiplication and release activities in accordance with the requirements of the Ministry of Agriculture, and further create a good atmosphere of “protecting natural waters and protecting fish ecology” for the whole society.
The method of multiplication and release has a good effect on the restoration of fishery resources and the restoration of unique species. The scientific name of Xinjiang bighead fish released this time is aquatic wild animals under national protection. The protection level is the same as that of giant pandas and snow leopards. It is only distributed in Xinjiang’s Tarim River Basin. Bighead fish used to be the main economic fish in Bosten Lake, with an annual output of 300 to 400 tons. Affected by water conservancy projects and overfishing, it gradually disappeared from Bosten Lake in the late 1970s. Only about 1,000 big fishes have grown up now.
The Xinjiang Fisheries Department has artificially propagated the fry of this endangered species through the Xinjiang Bighead Artificial Breeding Base in Aksu. Since 2005, the fish fry have been released in the Kizil River and other waters every year, hoping to make the bighead fish again. Appear in people’s daily vision. It is understood that since 2005, 740,000 bighead fish fry have been released from Xinjiang. In 2008, the discovery of bighead fish has been reported in the Muzhati River and other places in Baicheng County, and the found bighead fish is about 50 cm. This shows that the long-term release has played a certain role in the recovery of the number of bighead fish.
It is worth mentioning that the fishes released this time have been electronically marked. The fishery administration staff injected a rice-sized permanent chip called a radio frequency electronic tag into the big head fish fry in advance. After the injection, the detector will show that it has been marked near the fish, and the fish will be displayed on the detector at the same time. Release batches and other information. This method will provide technical support for the fishery department to track and detect the release and growth of bighead fish species in various water areas in the future.
