Background technique

The alpine region in western China is rich in water resources, which is the focus of recent and future water conservancy and hydropower development. While hydropower brings economic and social benefits, it will also hinder fish germplasm and affect the aquatic biological environment. With the continuous improvement of environmental protection policies and the continuous increase of environmental supervision of construction projects, a series of protection measures through the study of fish habits have become a necessary measure for the protection of aquatic ecology in hydropower projects.

The main characteristics of the climate environment in alpine regions are as follows: First, the sunshine time is long, and the annual sunshine time is between 2500 and 3300 hours, which is 1.5 to 2.5 times that of inland cities. Second, the solar radiation is strong, and the annual ultraviolet radiation in Lhasa is about 7900MJ/m ² . Third, the daily temperature difference is large, and positive and negative temperatures alternate frequently. Due to the special climate characteristics, there is a big difference between the indoor environment and the external natural environment. Human beings cannot fully study and observe the living habits of unique fish in alpine and high-wave regions under indoor conditions. The scale is small, and there is no condition to adjust the temperature difference of the water body itself. The water body in the fish pond is prone to extremely hot or cold conditions, which is not conducive to fish life and breeding.
