Recently, the Wuhan Institute of Aquatic Sciences of the Chinese Academy of Sciences announced that the Baishazhou waters of the Wuhan section of the Yangtze River are forming a stable porpoise habitat group.

"This is another positive change that has emerged after the ban on fishing in the Yangtze River." Professor Wang Kexiong of the Institute of Aquatic Life said that it is forbidden to catch and withdraw from fishing, shoreline rectification, and standardized sand mining... On March 1, with the official implementation of the Yangtze River Protection Law, the Yangtze River Protection Strategy will bring more positive changes.

Get out of the circle of fish catching less and less, the fewer and more monsters

The area of prohibited fishing is nearly 10 million mu

Since February, many Yichang residents have photographed porpoises playing in the water by the river.

In addition to the increase in finless porpoises. Recently, researchers from the Jiang Fisheries Research Institute of the Ministry of Agriculture and Rural Affairs found a helio in the Yichang section of the Yangtze River. Heels were once an important economic fish in the Yangtze River Basin, due to overfishing and environmental changes and other reasons, the number of hewl has been listed as a provincial key protected aquatic wildlife in Hubei, Hunan and other places.

"Now, the helio population is starting to recover gradually, thanks to the early closure of fishing in Yichang." In recent years, researchers from the Yangtze River Institute have been on the Yangtze River and undertaken the heavy task of aquatic resources investigation. He believes that with the continuous development of the ten-year fishing ban, the size of common fish stocks on the Yangtze River will increase significantly, and the populations of some threatened fish will be restored.

Monitoring of the Yangtze River Institute for many years shows that the water quality of the main stream of the Yangtze River is generally excellent, except for total nitrogen and total phosphorus, the remaining indicators are generally close to class I to class II water quality. Moreover, with the deepening of shoreline improvement, the two sides of the Yangtze River have become greener and more beautiful.

The Yangtze River, which is more than 6,300 kilometers long, is an integrated aquatic biological system with 435 species of conventional freshwater fish, however, from 2017 to 2019, the Yangtze River Institute's scientific survey found only 318 species. The Yangtze River biodiversity index continues to decline, many rare species are on the verge of extinction, and the ecological environment continues to deteriorate.

Zou Guiwei, a researcher at the institute, revealed that in the 1950s, the annual catch of the Yangtze River was 430,000 tons, and in recent years, the average annual natural fishery catch output of the Yangtze River has dropped to about 100,000 tons, basically losing its economic value.

The fewer the fish are caught, the fewer the catch, the more "electric fishing" and "nets" are more and more, and the aquatic biological resources of the Yangtze River have fallen into a strange circle.

On the basis of the ban on fishing in 83 aquatic biological resources conservation areas in the province on January 1, 2020, in accordance with the national deployment, from January 1, 2021, the key waters of the Yangtze River Basin will be fully banned from fishing and retired. With the "ten-year fishing ban" action, reverse the deterioration trend of the ecological environment of the Yangtze River, and let the aquatic organisms of the Yangtze River recuperate. Hubei's 1,061-kilometer Yangtze River and 858-kilometer Han River, as well as 83 aquatic biological reserves, have a total prohibited area of nearly 10 million mu.

The intensity is unprecedented, which will bring hope to the Yangtze River to get rid of the "no fish" level.

Should be supported to the fullest should be guaranteed

All the fishermen came ashore

"Protecting the Yangtze River is our unshirkable responsibility." In the past few days, at the fishing wharf of the Yichang section of the Yangtze River, Liu Qisheng, a "dolphin guard", took a patrol boat to observe the activities of rare aquatic animals while checking whether there was illegal fishing.

After 40 years of fishing, Liu Qisheng has witnessed the ups and downs of fishery resources in the Yangtze River. "Banning fishing" is imperative, but Lao Liu doesn't know what he can do. He was very happy that the government had hired him and more than 10 veteran fishermen as "dolphin keepers".

"I patrol the river every day, and recently I can see the porpoise almost every day, and we have banned fishing early in this section of the river, and the food is sufficient, and the porpoises are coming."

After the ban on fishing, there are a total of 32,226 registered fishermen in the Hubei section of the Yangtze River Basin, and through various methods such as financial subsidies, employment services, skills training, entrepreneurship support, and social security, fishermen on the shore should be supported and guaranteed, and no household or person should be left behind.

Dozens of aquaculture training courses have been held in various parts of the province, and fishermen have become fish farmers; various departments have joined forces to help fishermen find jobs and become class people after landing; some fishermen have taken advantage of the east wind of rural revitalization to set up farms and homestays... At present, all 31,999 retired fishermen who meet the conditions for insurance are insured, and the participation rate of retired fishermen in social endowment insurance is 100%.

16,818 fishing vessels and 17,462 fishing-related "three noes" vessels were all recovered or dismantled.

Forcing the transformation and upgrading of the aquaculture industry

Artificially farmed river fresh will be on the table

The Yangtze River is forbidden to fish, can you still eat jiangxian? How will it impact the aquaculture industry in our province?

"The wild river fresh is gone, but the artificially farmed river fresh will soon be served on the public's table." Wuhan Academy of Agricultural Sciences has explored the 'rice - shrimp - warsaw pond fish' breeding mode, mu average income increase of more than 1,000 yuan, at present, our province has selected 10 counties and cities to carry out shrimp, rice, warsaw pond fish co-cultivation, this year's artificial breeding of river fresh can be successively served on the people's table. The relevant person in charge of the Provincial Agricultural Development Center revealed.

As a major aquatic province, the ban on fishing in the Yangtze River has forced our province to speed up scientific and technological research, and 6 kinds of wild fish of the Yangtze River, such as Yangtze River knifefish, Zhonghuatang snakehead (commonly known as Tu huanba), copper fish (commonly known as golden loach), long snout (commonly known as Jiangtuan), Periwink (commonly known as grass bream), and large finned bream (commonly known as river rats) have gradually been successfully artificially bred. Relevant experts of the Provincial Institute of Water Science revealed that the rivers that have been listed so far rarely have the Middle Warsaw Pond Fish and Long Kiss.

"The ban on fishing in the Yangtze River has brought rare opportunities for the transformation and upgrading of Hubei's aquatic industry, and promoted the transformation of Hubei from four major fish to higher profitable special fish." Hubei has ranked first in the country in aquatic product production for 24 consecutive years, and the emergence of these 6 fish will be a good opportunity to drive Hubei's transformation from a large aquatic province to a strong aquatic province. Huang Guoxiong, director of the Provincial Agricultural Development Center, said.

Cao Wenxuan, an academician of the Chinese Academy of Sciences, is the first scientist to advocate the ten-year ban on fishing in the Yangtze River. He introduced that from 2016 to 2019, China's freshwater aquaculture output was around 30 million tons, "China's per capita consumption of 'four big fish' 9.4 kg." ”

The reporter found in the provincial market investigation that after the ban on fishing, there was no major fluctuation in fish prices, and the prices of crucian carp and other species fell all the way.

"Artificially farmed fish are cheap and good, but if you want the people to always have fish to eat and good fish to eat, we must protect the natural germplasm resource bank of the Yangtze River." Cao Wen declared, "The artificially bred fish species come from those parents, and long-term breeding will degenerate, and the germplasm bank of the Yangtze River is needed to improve the variety." ”

"For the sake of future generations, for the sake of the overall situation." Ten years of ban on fishing and retiring from fishing will bring us a more beautiful and better mother river.
