Fun Chinese Paddlefish Facts For Kids

Are you interested in rare and unique species? Then you should go through this article about the Chinese Paddlefish, who are not related to sharks.

Chinese Paddlefish (Psephurus gladius), also named as Chinese swordfish, was a relative of American Paddlefish. These species were only found in China and were one of the largest freshwater fishes. The fish that was native to the Yangtze River and Yellow River basin was good at maintaining the ecological balance in the Yangtze River.

The once-endangered Yangtze fauna has now gone extinct. Due to overfishing and habitat loss, the unique species had to face extinction.

The now functionally extinct species was once of the main predators of the Yangtze River. The Chinese Paddlefish population had been protected by law since 1983. The large freshwater fish was easy to capture, and thus the once-endangered Yangtze ultimately faced extinction.

However, before extinction, the species showed great uniqueness and interesting characteristics. Keep reading to know more about Chinese Paddlefish.

The sperm and the eggs were mixed and fertilized together. Small and almost undeveloped young fishes used to hatch after a few days. The young ones were left all alone to fend for themselves.

The species were considered to be Endangered back in 1983 and were under first-level protection by the People's Republic of China ever since. Due to loss of habitat and overfishing, the world had to bid goodbye to this unique species native to the Yangtze River.

A fully grown adult Chinese Paddlefish was never threatened by any other species from its natural habitat. However, the young ones and the vulnerable eggs used to face attacks from various fishes.

Chinese Paddlefish extinction

One of the world's largest freshwater fish was considered endangered in 1983 but was officially declared extinct in 2020. The reason behind this extinction is mostly habitat loss and overfishing.

This species was an easy target of fishermen of Yangtze as it required no effort to catch them, and they were caught easily. The construction of the Gezhouba dam building is also a reason behind their extinction. Apart from that, their breeding was restricted; thus, the number of species gradually decreased.

Chinese Paddlefish in the food chain

The presence of species that are higher up in the trophic level is extremely important to keep the food chain going smoothly. When a top predator is lost, a cascading effect will be seen.

Chinese Paddlefish, being a top predator, used to keep the food chain run effectively. The loss of someone who eats higher up in the food chain will affect the total environment and challenge the river's ecosystem.

Some species of the Yangtze river will keep on expanding while others will keep on decreasing. So the functionally extinct status of Chinese Paddlefish has and will continue to have a serious effect on the ecosystem of the Yangtze River.
