Previously, many people for their own interests, often in the Yangtze River, a large number of fishing Yangtze River white sturgeon, and before our country does not have the Yangtze River fishing ban. With the passage of time, more and more people around the Yangtze River Basin began to fish the Yangtze River white sturgeon, want to get more benefits, and this is actually one of the reasons that led to the extinction of the Yangtze River white sturgeon.
02, the Yangtze River white sturgeon loss of habitat.A species if you want to better survive, then there must be a very good habitat, only then can better to reproduce offspring. However, mankind in the Yangtze River Basin built a lot of dams, and these dams are also blocking the Yangtze River white sturgeon migration routes. In addition, mankind is also in the Yangtze River Basin for continuous gravel mining, which is also the destruction of the Yangtze River white sturgeon spawning place, it is because of these two reasons, so it is also lead to the Yangtze River white sturgeon habitat is completely lost, and ultimately slowly to the extinction.
03, water quality has been seriously affected.While the Yangtze River in recent years after the governance, water quality has slowly improved, but in the past due to the impact of urban sewage, by the impact of industrial wastewater, the Yangtze River's water quality is relatively poor, and this is also a direct impact on the survival of the Yangtze River white sturgeon. You know, the Yangtze River white sturgeon this creature on the water quality requirements itself is very high.
04, because of the extreme weather, so it caused the unsuitable temperature.In recent years there are actually more and more extreme weather, either the weather will be particularly cold, or the weather will be particularly hot, and this is the survival of the Yangtze River white sturgeon is also a very big impact. When extreme weather occurs, the water temperature in the Yangtze River will naturally be affected, it is because of this cold and hot water temperature, so it is also directly lead to the extinction of the Yangtze River white sturgeon.
In addition to these reasons, in fact, there are many reasons, such as the Yangtze River itself is a waterway, so there are some of the Yangtze River white sturgeon is also killed by the propeller of the ship.
