An ecological survey is the process whereby a proposed development site is assessed to establish any environmental impact the development may have. With any potential new land development, along with cost estimates, insurance, structural warranty, and planning permission, you will need to conduct various site surveys, including an ecological survey.
An important type of hydrographic surveys is the bathymetric survey, which originates from the Greek terms bathus (deep) and metron (measurement). This is the underwater equivalent to a land survey operation known as hypsometry.
Learn MoreIn January 2024, the Yangtze River Biodiversity Research Center of the Three Gorges Group Ecological Engineering Center (hereinafter referred to as the Biodiversity Center) conducted a natural spawning experiment of split belly fish in the natural river channel of the Heishui River tributary, successfully achieving natural reproduction of split belly fish in the wild. The successful implementation of this experiment provides an example for research on the restoration of fish habitats in the upper reaches of the Yangtze River.
On April 12, 2015, the Three Gorges Group and the Yichang Municipal People's Government jointly hosted the 2015 Yangtze River Three Gorges Chinese Sturgeon Release Event at the Yanzhiyuan Yangtze River Rare Fish Release Point. The World Wildlife Fund, Nature Conservation Association, and others have provided support for this activity. This event is the 57th time that the Chinese Sturgeon Research Institute of Three Gorges Group has launched a Chinese sturgeon release activity, releasing a total of 3000 second-generation Chinese sturgeons.
On the morning of April 12th, China Three Gorges Corporation held the 57th Chinese sturgeon release event, releasing a total of 3000 second-generation Chinese sturgeons from large-scale grids, which is currently the largest release of second-generation Chinese sturgeons from large-scale grids. At the same time, the Chinese Sturgeon Research Institute will use real-time transmission technology at various monitoring stations along the river for the first time to fully monitor the migration information of released Chinese sturgeons.
