According to a report by Nippon TV on April 6, in the past two years, the sea surface water temperature off the coast of Japan has continued to hit the highest record, triggering changes in the ecosystem of Tokyo Bay, and some "strange scenes" have emerged.
In recent years, the coral reefs in Tokyo Bay have been growing rapidly, and a large number of corals are thriving on the ocean floor, and the variety is gradually increasing. Researchers at the University of Tsukuba believe that if the sea temperature rises, the growth rate of corals will also increase. The growth of these coral reefs has not only changed the landscape of the seabed, but also affected the surrounding ecological environment.
However, this change has also caused problems for fishermen in Tokyo Bay. They found that the number of fish in the warm sea was increasing, and the species of fish were changing. As a result, many fishermen have had to change careers because the fish they used to catch are no longer available. According to the staff at Katsuyama Fishing Port in Tokyo Bay, the fish they catch now are all tropical fish, which has a great impact on their fishing business.
Su Jilan, an academician of the Chinese Academy of Sciences and a physical oceanographer, pointed out that the ocean is vital to the earth and mankind. It not only provides a large amount of high-quality protein for humans, but also contributes 50%-85% of the world's oxygen and absorbs about 40% of human carbon dioxide emissions since the Industrial Revolution. Without the absorption of carbon dioxide by the oceans, global temperatures would rise faster than they do today.
Rising seas are creating challenges for the marine fishing industry. Traditional fishery resources may be reduced, and new fish species may need to adapt to new fishing methods and techniques.
Looking back at the mainland marine fishing industry:
The continental marine fishing industry is an important pillar industry, with abundant fishery resources and diversified fishing techniques. The mainland has a large fishing fleet and advanced fishing equipment and technology, which can effectively carry out various types of fishing activities, including the exploitation of fishery resources, the processing and marketing of aquatic products, and so on. At the same time, the mainland's marine fishing industry is also constantly promoting scientific and technological innovation and sustainable development, and is committed to protecting the marine ecological environment, improving the sustainable utilization rate of fishery resources, and promoting the growth of fishermen's income and the development of fishery economy.
-- In recent years, the total amount of aquatic fish has been declining continuously
Zhejiang is one of the provinces with the most developed marine fishing industry in mainland China, and has been ranking first in the country in terms of marine fishing output value and output for many years. As of 2020, Zhejiang's total output of marine captured aquatic products was 2.5686 million tons, a decrease of about 900,000 tons from 2015, accounting for 27.1% of the country's total aquatic and marine fishing output.
Analysis of China's marine capture production
In 2020, fish was the main type of marine fishing products, accounting for 68.48% of the total output, reaching 6,487,800 tons, and the crustacean fishing output was 1,810,800 tons, accounting for 19.11% of the total output. Other types of aquatic products accounted for less than 5% of the catch.
The mainland is rich in marine resources, and the marine fishing industry has great potential for development. With the continuous innovation of marine fishing technology on the mainland, the continuous upgrading of marine fishing equipment, and the continuous improvement of the marine fishing industry chain, the marine fishing industry has become one of the important strategic emerging industries in the mainland. With the continuous improvement of marine fishing technology and equipment, the continental marine fishing industry will usher in a broader development prospect.
