The ban on fishing in the Yangtze River - Many people may think that it is only a "ban on the Yangtze River area". In fact, it is not the case. In addition to the Yangtze River, many major rivers, rivers and other areas in our country are implementing "fishing ban" plans.
Of course, there may be certain differences in fishing closure periods in different areas. But overall, to protect our ecosystem, all areas must be closed to fishing. This may be the best thing. As the saying goes, if you want to recover, recover together. This is the best thing.
Of course, although the fishing ban in my country’s Yangtze River has not been long, we have also seen the recovery of many biological populations. No, the news about "a large number of fish migratory and spawning in Anji, Zhejiang" has come again during this period, allowing us to once again see the benefits of protecting the ecosystem.
haven’t seen it in over 40 years! A large fish population appears in Anji, Zhejiang.
Compared to Anji, Zhejiang, the ecosystem in this area is very good, and the resources in the area are very rich. Among them, there are special economic plants in the territory - Eucommia ulmoides, Echinacea cypress, Tung tung tree , Camellia , Magnolia officinalis and other plants, as well as endemic plants Money pine , White taxus , Magnolia officinalis and so on.
There are also many animal resources, including more than 30 species of mammals, about 100 species of birds, and more than ten species of reptiles. Therefore, it is indeed a good ecological area.
Of course, in addition to animal resources, water resources are also very famous. Mainly composed of two large reservoirs, Fushi and Laoshikan, the total storage capacity of various reservoirs reaches 400 million cubic meters, the hydropower resource reserves are 77,000 kilowatts, and there are several small hydropower stations with an annual power generation capacity of more than 100 million kilowatt hours. The Tianhuangping pumped storage power station with a total installed capacity of 1.8 million kilowatts is located within the territory.
So, water resources are quite abundant. That provides a foundation for the survival of aquatic life . In addition, there are mineral resources, including 42 kinds of metal and non-metal mineral deposits, of which the reserves of bentonite are more than 20 million tons.
This is the resource of Anji, Zhejiang, which is indeed a relatively rare area. In late June 2022, we saw the emergence of large-scale fish schools in Anji, Zhejiang, which also shows that the ecosystem in the area is very good.
According to the report, large-scale fish activities were encountered in the Anji section of Xitiao River. This is the period when fish migrate, so we saw such a scene. According to local people, this is the first time they have seen it in this area for more than 40 years. They have never seen such a scene before. This is a very rare thing.
It is normal for fish schools to go through all kinds of difficulties and swim upstream. It is normal for white fish , yellow and white fish, etc. to compete to migrate to Anji to lay eggs. Therefore, after everyone sees it, you must protect it well and not fish the fish in this area casually.
Where did the large fish schools come from?
For many people, they may think that even if fishing is banned in the area, there should not be so many fish. This is a bit unscientific. In fact, there are two main reasons that affect the fish. Appear.
First, that is Anji County itself has implemented a fishing ban. A plan has been implemented for rivers, water sources and other areas in the county to exchange "no fishing" for ten years for fish every year. This will definitely be good for the growth of fish. If no one fishes, the fish will appear. In the case of large-scale reproduction, a growth pattern will appear.
Secondly, there is an artificial reason in , which is to carry out proliferation and release . This method also assists in the expansion of fish through artificial intervention and provides assistance in the recovery of various biological populations. According to data released by the Anji County Agriculture and Rural Affairs Bureau, 10 to 20 million fish are released into Xitiao River every year. Therefore, through a series of measures, it is completely normal for the fishery ecology of Xitiao River to be restored organically and regain its vitality.
However, the large-scale fish migration this time has little to do with these two. Because it is a school of fish that migrates from Taihu to Anji to spawn.
Why did Taihu fish enter Anji? Taihu Lake is familiar to many people. It is one of the five largest freshwater lakes in my country, ranking third. According to the "Taihu Lake Fish Chronicle", there are 107 species of fish.
Therefore, the number is quite large, and the most typical migratory fish include eel, anchovy , Oriental puffer , grass, green, silver carp and bighead carp and other fish. The white fish, yellow and white fish and other fish that appeared this time are only part of them.
However, human activities and environmental changes have had a great impact on the entire Taihu Lake and the Taihu Lake water system. Especially in the 1950s and 1960s, the construction of a large number of gates and dams along rivers and lakes, the "lake reclamation" in the 1960s and 1970s, and the use of destructive fishing gear and fishing methods have led to large-scale migratory and semi-migratory fish species. and the reduction of spawning resident fish stocks in coastal zones, resulting in severe ecosystem transformation and large-scale fish declines.
However, only the population of young water-based fish in the lake has gradually increased under artificial breeding protection measures, and finally formed a Taihu Lake fish resource pattern dominated by swordfish, whitebait , etc. and with large annual changes.
Therefore, the original distribution of biological resources in Taihu Lake has been changed. However, in a state of poor resource distribution, our country has protected the entire Taihu Lake and the Taihu Lake water system, and we have also seen the recovery of other fish populations.
After the fish stocks recovered, the protection of Xitiao Creek also achieved obvious results. The most critical point is that Xitiao Creek is an important tributary of the upper reaches of Taihu Lake. It is an important channel connecting Taihu Lake.
So, after the population expanded, we also saw large-scale fish migration, and that's it. Because the ecosystems in both areas have undergone changes, become better, and are suitable for their survival, they are also migratory areas themselves. Therefore, I saw such a scene now. This is how it came about, so don’t be surprised.
Summary
This once again proves a problem, that is, the protection of the ecosystem needs everyone to work together. Whether it is an important river or a water source tributary area, we should effectively protect it, so that we can see more Creatures appear.
After the fishing ban was implemented in the Yangtze River, other large and small rivers in our country also implemented the same plan, which also allowed us to see the recovery of biological populations. This is indeed good news. In the future, we may even encounter biological populations that occur once in a century. The most important thing is to continue to work hard, protect water sources, and protect the ecosystem.
Don’t think that protecting the ecosystem is harming your own interests. If we don’t protect it, we may have “no fish to eat”. This sentence makes sense.
Even fry are not given a chance to grow, and they are destroyed on a large scale. How can we still see fish? And after our country implemented the fishing ban plan, it also provided certain subsidies, which can also relieve everyone's pressure. Therefore, everyone should pay attention not to see the recovery of biological populations - large-scale fish activities and want to catch fish. That is illegal.
