Chinese sturgeon The Chinese sturgeon is an ancient and rare fish endemic to China. As far back as the Zhou Dynasty more than 1,000 years BC, the Chinese sturgeon was called the king tuna. It has a pointed snout, a small toothless mouth, and an oval cylindrical body.
There are four tentacles in front of the mouth, which are used to search for invertebrates, small fish, and other food at the bottom of the water. The Chinese sturgeon is a large migratory fish. Like nomads, they are born in rivers and oceans, where they grow and develop, and it takes about 9-12 years to mature.
After it is fully mature, it migrates to the shallow sea area of China and enters the estuary, where it fattens and inhabits. In autumn, it travels upstream, up the Yangtze River, until the Jinsha River in the upper reaches of the Yangtze River to lay eggs and reproduce. After hatching, the juveniles follow the broodstock expedition and swim towards the estuary and ocean.
Chinese sturgeon have a very long lifespan, one to two hundred years. The body of the fish can be more than 2 meters long, and the weight of the female is about 2 to 300 kilograms. Chinese sturgeon has fatty meat and eggs can be used to make caviar, which is a precious food; The swim bladder and notochord are used to make fish gelatin, so they have been overfished in the past.
Many water conservancy projects have also seriously affected the natural resources of this fish due to the neglect of ecological balance. The Chinese sturgeon is now in danger of extinction and requires strict protection.
Habitat destruction of Chinese alligators: Due to the continuous growth of population, the economic activities of reclaiming wasteland, enclosing lakes and building roads, the habitat of the Chinese alligator has decreased, and the Chinese alligator is an animal that lives in a fixed hole, and the destruction of the habitat environment has destroyed its habit of living in a fixed hole, and the Chinese alligator has also left the environment of this fixed hole and moved to other places, and in the process of relocation, it is often hunted and killed.
Hunting as a pest: Because the Chinese alligator has the habit of building burrows, occasionally burrowing in the embankment, and because it is a carnivore, it preys on the domestic fish stocked in the pond, and sometimes climbs to the rice field to crush seedlings or other crops, so the people in the production area will kill it as a pest, and even poison it with medicine. During the breeding season, the people in the production area will smash the nest and destroy the eggs, so that the population cannot be replenished.
Environmental pollution: The heavy use of pesticides and fertilizers has led to a decrease in food for Chinese alligators, which is also a factor in the decline of the population.
Tibetan antelope The Hoh Xil Nature Reserve in the plateau desert is the habitat of the Tibetan antelope, after millions of years of optimization and selection, the extremely tenacious Tibetan antelope has become an excellent species only existing on the Qinghai-Tibet Plateau, but the survival state of the Tibetan antelope is worrying, the local ecological environment is also extremely fragile, once it is destroyed, it will be difficult to recover, coupled with the crazy indiscriminate hunting and killing, the number has decreased sharply.
