China’s four famous fishing grounds are yellow sea and Bohai Sea fishing grounds, southern coastal fishing grounds, Zhoushan fishing grounds and Beibu Gulf fishing grounds. However, due to the serious damage and overfishing of human beings, the four major fishing grounds are now dead in name. Fishing grounds begin to “Desertification”. People think that fishing grounds are inexhaustible and inexhaustible. These four fishing grounds are also a great temptation for fishermen. For people’s interests, they forget the limits of fishing grounds and go crazy fishing. With the emergence of radar net, bottom trawling net, enchantment array and light net, it is hard for marine creatures to escape death. Gradually, various regions begin to reclaim land from the sea and expand fishing Half of the natural coastline disappeared.
At that time, the Bohai Sea fishing ground was the largest fishing ground in China and the most important marine resources in China, but now it has become a “waste water tank”. Not only the Bohai Sea has perished, but also Zhoushan fishing ground has begun to accelerate its demise. Not only that, we know that coral reefs are the most important marine ecosystem in the ocean. Coral reefs have nurtured a variety of marine organisms, but now the destruction of the ocean by human beings has caused great damage As a result, the sea water becomes eutrophic, forming our common red tide, blocking the sunlight and air, not only killing the marine life, but also gradually disappearing the coral reefs. But once the four major fishing grounds, do you remember how prosperous it was?
The past prosperity of China’s four major fishing grounds
Zhoushan fishing ground
There are many fishing grounds in China’s coastal areas, but these four fishing grounds have the largest amount of fish. They have made important contributions to China’s fishery development. First of all, Zhoushan fishing ground, the largest fishing ground in China, is the first of the four major fishing grounds. It is located in the east of Hangzhou Bay, near Zhoushan Islands, and in the northeast of Zhejiang Province, Southeast of the Yangtze River Estuary. It can compete with Newfoundland fishing ground in Canada, Peru cold fishing ground in the world’s four major fishing grounds, and has a super fishing ground comparable to thousand island fishing ground in Russia. In the past Zhoushan fishing ground, there were countless schools of fish, including a variety of fish species. It was also the main fishing industry of the four economic fish. But now people’s destruction, less and less fish, if it continues, there will be no fish to catch.
Yellow Sea and Bohai Sea fishing ground
The Yellow Sea and Bohai Sea fishing ground is located in the west of 119 degrees east longitude, covering an area of 3600 square kilometers. It is also rich in many kinds of fish species. From April to November every year, we gather a lot of familiar hairtail, small yellow croaker and other seafood. But now, in recent years, a large number of oil exploitation in the Yellow Sea and Bohai Sea has affected the ecological changes of the fishing ground, and there are many fossils in the area around the Bohai Sea, which seriously damage the fishery resources, and the fishing ground is gradually dying out.
Beibu Gulf fishing ground
Beibu Gulf fishing ground is located in the northwest of the South China Sea, with a total area of 26000 square kilometers. It is rich in plankton, mainly flounder, tuna, scallop, etc., and its bait is also particularly abundant. It is one of the excellent fishing grounds in China. Besides, there are many mangroves along the coast, and natural gas resources are also very abundant.
Southern coastal fishing ground
As the name suggests, the South China Sea fishing ground is the largest tropical fishing ground in China. There are more than 400 kinds of marine organisms living here, such as sea cucumber, abalone and other precious products. However, due to over development and sea water pollution, and over breeding, serious eutrophication has been caused, so the fishing ground is in name only, and now it is also facing the phenomenon of no fish.
Current situation of fishing ground in Bohai Sea
Nowadays, there are less and less fishery resources in the Bohai Sea. However, since 1980, overfishing, wanton marine pollution and other reasons have caused serious damage to the ecological environment of the Bohai Sea, from 95 species in that year to about 10 species. Now only skin shrimp are caught, and the specialty hairtail of traditional fishery has almost disappeared. The main reason why the Bohai Sea has become like this is land-based pollution, that is, human pollution, including the inflow of various heavy metals. More than half of the cities along the coast of the Bohai Sea have sewage outlets, which directly flow into the sea for agricultural and industrial sewage. Nowadays, fishermen in the Bohai Sea are also very distressed. They can’t catch fish and have no source of income. People can’t eat fresh seafood. What should they do?
Current situation of Zhoushan fishing ground
As the largest fishing ground in China, it has provided a huge fishing ground for fishermen in Zhejiang, Fujian, Jiangsu, Shanghai and other regions since liberation. In the 1950s and 1960s, the total fishing output of Zhoushan fishing ground alone accounted for 10% – 20% of that of China at that time. It can be said that Zhoushan fishing ground at that time was half of the sky that China caught at that time.
However, after giving back to the fishermen for more than 50 years, the output of Zhoushan fishing ground has decreased year by year, and even around 2010, Zhoushan fishing ground has been facing the crisis of “no fish to catch”. So what is the reason that a prosperous fishing ground is now facing the danger of “bankruptcy”?
“Don’t say it’s big fish, small fish, young fish, fish eggs can be fished up for you.”
This is what the fishermen of the fishing ground said in an interview. Zhoushan fishing ground has been prosperous and rich in the last century, but now it is desolate. There are many reasons for people’s overfishing, such as radar net and bottom trawling net. Since China’s subsidy policy for fishing boats in the East China Sea came down in 2006 (the subsidy is determined according to the power of fishing boats), many fishermen began to “struggle to be big boats”. According to media reports at that time, more than 200 high-powered fishing boats were added in Wenling in 2006 alone. The power of fishing boats is directly proportional to the fishing capacity, which is natural and reliable However, Zhoushan fishing ground is in the situation of less and less fish.
According to statistics, there are more than 12000 Sanwu fishing boats in Zhejiang Province, and less than 20000 fishing boats have formal fishing licenses. In addition, people overfishing, using illegal fishing gear (at that time, the government issued a policy to specify the minimum size of fishing nets, forbidding the use of many illegal fishing gear), and not letting go of fish eggs. The ecological balance of Zhoushan fishing ground has been broken, resulting in a rich production of many kinds of fish To the brink of extinction.

2、 Environmental pollution
We should all be familiar with the four sea areas in China, namely the “Bohai Sea, Yellow Sea, East Sea and South Sea”. The East China Sea, as an important “important marine area” in China, is also the most serious in terms of pollution. In 2012, there were 78 red tides in China, and the East China Sea alone accounted for nearly half to 38. In 2019, according to the investigation of China’s environmental protection agency, the polluted area of the East China Sea has reached a terrible 50000 square kilometers. You should know that the total polluted area of the other three major sea areas is only 37000 square kilometers. Therefore, the East China Sea has become the “Dead Sea” in the eyes of many people, and the Zhoushan fishing ground in the East China Sea has gradually declined Say that human beings have an inescapable responsibility!
Coral reefs are the biggest victims of marine pollution
Mention coral, people can’t help but think of that kind of beautiful marine life. The vast majority of coral reefs are built by stony corals. They gather together and become a beautiful scenery in the underwater ecosystem. Of course, coral reefs are not only beautiful. Shallow coral reefs are known as “tropical rain forest in the ocean”. Although coral reefs account for less than one thousandth of the world’s ocean area, they are one fourth of the ocean Species provide habitat. Moreover, coral reefs have great significance in promoting the development of tourism industry.
In the South China Sea alone, the economy of coral reefs has reached 15.65 billion yuan. However, due to human unreasonable exploitation and self factors, coral reefs have been seriously damaged. According to the survey, as the largest area of coral reefs in China, the South China Sea. In recent years, coral reefs in China have been seriously degraded. The total area of coral reefs in Southeast Asia is more than 90000 square kilometers, of which 38% have been damaged, and about 28% are in critical condition. Among Southeast Asian countries, the destruction rate of coral reefs in Malaysia is 20%, that in Thailand and Philippines is about 50%, and that in South China Sea is 80%. If this situation continues, experts predict that most of the coral reefs in the world will be destroyed within 100 years, and the consequences can not be estimated. How do we deal with all kinds of situations?
As we all know, the productivity of coral reef ecosystem is very high, but its self-regulation ability is very low, and it is very fragile. If the temperature fluctuates greatly, the coral reef will quickly become albino, and will die after a long time. Excluding the irresistible factors (natural factors), what we can do is to do our best to maintain the ecological balance of coral reefs: China has always attached great importance to the coral reef ecosystem. In the 1990s, the Coral Reef Nature Reserve in Sanya was one of the five marine reserves in China. It not only promotes the development of tourism industry, but also keeps the coral reef ecosystem from being damaged. China has also issued corresponding policies to prohibit the use of explosives for fishing, and to prohibit the use of toxic fishing and other measures, because coral is of great artistic value. Hainan Province, as a major coral Province, has also issued the “Regulations on the protection of coral reefs in Hainan Province” to protect this fragile ecosystem and return corals to a safe “home”
The ocean is about 71% of the earth’s surface area. The marine environment has a great impact on the world’s climate, temperature and so on. “Life originates from the ocean”, so the protection of the marine environment is particularly important, especially in China. The law of the people’s Republic of China on marine environmental protection was officially revised and promulgated on December 25, 1999. It was revised and implemented again in 2017. In these years, our measures for marine environmental protection have not stopped. Among them, we have established more than 80 marine reserves and 24 national marine reserves. The government calls on people to “the beach will not become clean by itself, and the ocean will not become clear automatically”. For us, protecting the marine environment is actually very simple, reducing our own carbon dioxide emissions, taking the garbage away when we play on the beach, and eating seafood “in three colors” Wait, the ocean is inseparable from us. If we treat it well, it will naturally give back to us.
Well, the sharing of this issue is over. I hope these events will enlighten you. We also believe that our protection of the marine environment will become more and more important, and people will realize that man and nature are a whole, and we are inseparable.
