On July 21, 2022, the World Nature Protection Alliance (IUCN) announced two bad news: White 鲟 extinction, Yangtze River field extinction. In addition, 26 existing catfish in the world is also facing the risk of extinction. Although the Yangtze River has been announced in the wild, it has achieved artificial insurance. I believe that in the future, we may allow it to achieve the recovery of natural population. Moreover, some people have found that the Yangtze River 鲟, which has been announced by the " Wild Extinction " again!
Yangtze River again appeared in
. On the afternoon of September 6, 2022, the Hubei Provincial Tuanfeng County Fishery Political Law Enforcement Brigade received a call from the citizens. Citizen Wang found a big fish appearing on the beach while playing on the beach by the beach by , , and looked like a rare animal seen on TV. Therefore This big fish was rescued and placed in the water tank temporarily.
is identified by researchers. This big fish is the famous Yangtze River, which is the Yangtze River 鲟, which was announced by the World Nature Protection Alliance (IUCN) in July this year. Researchers said that the Yangtze River, which appeared in the water beach, was about 96 cm long and weighing about 4 kg. It was a sub-Cheng. He was aged 5-6 years old. The Yangtze River is a unique species in my country. It is currently distributed in the middle and upper reaches of the Yangtze River. In the case of survival in the wild, the Yangtze River can live to 2-30 years old. It is national first-class protection animal . Because the Yangtze River and China 鲟 look a bit similar, most people may not be able to distinguish between Yangtze River 鲟 and Chinese 鲟, and may admit it.
Study shows that around 2000, the Yangtze River in the wild may have stopped breeding natural生 has survived for a long time in the wild environment, and its physical condition is now very good. The researchers put it back to the Yangtze River after sampling the Yangtze River.
Yangtze River Fishing effect is significant.
has once again discovered rare animals that have been announced by the "field extinction" in the wild, which is indeed good news. Now we have taken a series of measures to protect these wild animals. For example, since January 1, 2021, the key waters of the Yangtze River Basin have been fully launched for 10 years. Since the implementation of fishing for 10 years, many water systems in the Yangtze River Basin have appeared in large -scale fish groups, and groups of fish groups that have been in groups have even "dyed" the water surface. In the Yangtze River for more than a year, it has achieved great results. Will there be more and more rare animals such as the Yangtze River and Chinese 鲟 in the future, until flooding?
We need to know that 10 years of banning fishing in the Yangtze River is not to protect a certain species, but to protect the entire ecosystem of the Yangtze River Basin. In the case of protecting the ecosystem, the size of various fish -like population living in the Yangtze River Basin may continue to grow. For example, the Four Persons in the Yangtze River Basin is the most common fish. It is expected that they can develop mature in about 4 years. During the 10-year fishing period, the four people can theoretically reproduce 2-3 generations. The scale of the population should continue to expand. The population of rare animals such as Chinese and Yangtze River is relatively small, and it will be more difficult to breed. In theory, it will not have explosive growth in theory in a short period of time. However, it is protected during the fisheries period, and these rare animals still have the opportunity to expand their population scale to a certain extent, thereby reducing the risk of extinction.
my country has two gibbon wild extinction
. Now there are many species we need to protect. Distributed white The two spiritual long -priests, and North White Belathalben , are already out of the wild.
was studied in the study. The researchers conducted a survey of the well -known distribution area and the surrounding area of the white palm gibbon, but no signs of white palm gibbon found in the wild. After investigating the habitat and distributed area of the North Baiqi Biben, there was no group of northern white cheeks gibbon survival in the wild, nor did they hear their tweets.
Perhaps, these wild animals may not completely disappear from the earth, but their population scale may be very small, and the breeding offspring may not be completed in natural state. Under such circumstances, even if certain species may not have completed extinction, their quantity may not be recovered, and extinction may be just a matter of time. If we humans do not stretch out a helping hand to save these wild animals in time, there may be more species that disappear in the future. With the disappearance of these wild animals, we lose not only a single species, but also may be greatly affected. After all, including the ecosystem and the food chain, including us humans. If large -scale species are extinct, the food chain and ecosystem may collapse, and we human beings cannot be alone.
