At present, the number of Chinese sturgeon surviving in the world is scarce, which has become a protected animal of the country, and the country has also carried out publicity for many years. Protected animals regarded as national treasures by the government and the public are specially protected. Scientists believe that ACIPENSER sinensis has survived for more than 65.438+0.4 billion years and is called the living fossil in China. The state publicizes the protection of Chinese sturgeon every year, which shows the importance the state attaches to it. However, many fishermen secretly left after hunting Chinese sturgeon, but this fisherman caught five Chinese sturgeons and released them. This behavior is commendable because it protects our country's? Living fossil? .

There are indeed many reasons why Chinese sturgeon is endangered, such as climate change, overfishing and environmental pollution, but the main reason is the construction of dams. According to statistics, the number of Chinese sturgeon spawning has been reduced by 97.5% due to the construction of Gezhouba and Three Gorges Dam, and it is impossible to return to the spawning ground located in the upstream, which makes its number drop sharply. Then the existence of the dam is really necessary and brings a lot of convenience to our life. Therefore, this requires our country to have more perfect remedial measures for these migratory fish, which can help them return to the upper reaches to lay eggs and let them thrive.

ACIPENSER sinensis can survive for 65.438+0.4 billion years, which shows that it has a strong ability to adapt to the environment, but why is the number of ACIPENSER sinensis decreasing sharply now? This is because our present people have caused great damage to the environment. The Chinese sturgeon is also adjusting itself to face the current environment as much as possible, but the sharp decline in the number of Chinese sturgeons can only show that the current environmental conditions are very bad. This also requires us to invest more money in environmental governance, invest more power to protect them, and call on all of us to start from the small things around us and protect our environment.
