CHN Energy Released 50,000 Fish in the National 100 Hydropower Stations Fish Releasing Campaign

Recently, on the occasion of the 52nd World Environment Day, the General Institute of Hydropower and Water Conservancy Planning and Design joined hands with 100 hydropower stations to launch the 2023 World Environment Day Hydropower Industry Fish Proliferation and Release Joint Action. CHN Energy set up a branch venue in Dadu River Company and successfully released 51,200 rare fish of six species, including Leptobotia elongata, in Ebian Yi Autonomous County, Leshan City, Sichuan Province that day.

During the fish release campaign, Dadu River Company released three species of fish under state second-class protection, including Schizothorax waltoni, Rhinogobio ventralis, and Leptobotia elongate. It is reported that the company will release a total of 1,808,700 rare fish in 10 hydropower stations at Shaping, Shuangjiangkou, Pubugou and other places this year, which will play a positive role in the protection of the Yangtze River ecosystem.

Over the years, Daduhe Company has built an ecological protection strategy integrating fish proliferation and release, fish passages and cascade joint ecological dispatch, and promoted the coordinated development of hydropower development and eco-environmental protection. In 2008, the Dadu River Basin Rare Fish Protection Research Center was established, taking the lead in Sichuan Province to carry out aquatic species breeding and release projects. Since 2010, three fish proliferation stations have been built in the upper, middle and lower reaches of the Dadu River, forming a breeding and releasing scale of 2 million fish per year, covering rare, protected fish species throughout the Dadu River Basin. The efforts focus on the proliferation, release and resource protection of about 20 rare fish species in Sichuan and Shaanxi provinces, including Hucho taimen, Schizothorax, Pareuchiloglanis, and Cobitidae. A total of 15 million rare fish have been released so far. In addition, 26 monitoring points have been built in the Dadu River Basin. Scientific research has shown that the released fish can effectively adapt to the wild natural environment and their reproductive capacity achieve the expected results.
