Can we still eat seafood happily when the ocean -off fishing period has arrived?

CCTV Beijing May 9th News According to the Voice of China Voice of the Central Radio and Television Studio "News Hyperlink", from May 1st, the four waters of the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea have entered the oceanovic season.Since its implementation of my country’s maritime -off fishing system for nearly 30 years since its implementation in 1995.Resource monitoring shows that after the implementation of the Fuxing season, marine fishery resources have been effectively recovered. China has re -entered the Bohai Bay.The number of high -quality fish species such as small yellow croakers has also increased significantly.

The recovery of fishery resources is gratifying, and as a consumer, the most concerned issue at this moment is -how to guarantee seafood freedom during fishing?In the seafood we usually eat, which ones are available through breeding?Why is the breeding of sea fish far from even more than Freshwater Fish?

Will the fishing period affect seafood freedom?

China has implemented the fishing period for nearly 30 years, and fishing is for the sustainable development of fishery resources.The seafood sources during the fishing rest period are mainly two aspects: seawater breeding and import.

Wang Yamin, a professor at the Marine Institute of Weihai Campus of Shandong University and a member of the Whale Stranging Working Group of the International Whaling Commission, said that through the two channels of seawater breeding and the import of seafood, it can provide the people with a very stable seafood consumption during seafood consumption during the ocean season.ensure.

First of all, seawater farming is not affected by fishing season, especially now the output of seafood products in China has gradually exceeded the yield of fishing.This method is not only conducive to the protection of natural resources, but also solves the problem of eating seafood by the masses of the general public.

Another channel is to rely on imports. Wang Yamin introduced that in the past, Chinese aquatic products seafood exports were greater than imports, but with the development of economic development and people’s income levels, the import volume of seafood in my country has increased significantly, and it has even become a very important seafood supply. channel.

Which seafood has been supplied through breeding?Why is the breeding of sea fish far from being less than to freshwater fish?

In fact, most of the seafood on the daily dining tables is mainly breeding, such as scallops, mussels, fish and shellfish, etc. Basically, they are basically aquaculture. Now few natural shellfish are sold in the market;Similarly, bibida, sea bass, sea cucumber, etc. are mainly breeding.

At present, only a few cities along the coast of China can still see some seafood through fishing, and more seafood flowing in inland cities depends on seafood breeding.Wang Yamin also mentioned that common algae, such as kelp, all of them are breeding. Even some seafoods that everyone thinks of "golden", such as barracudies, puffer fish, can actually rely on breeding to achieve supply supply.Essence

The breeding difficulty of different types of seafood is different from the breeding technology.For example, shellfish and algae are not very easy to move, it is easier to manage, it is easier to increase yield, and it is simpler to cultivate, while fish and crustacean seafood is more difficult to raise.The characteristics of these creatures have caused them to encounter many unpredictable risks in natural sea areas, and natural disasters such as typhoons will cause production reduction.

In terms of fish alone, high -density breeding needs to be cast in bait, which has certain requirements for the area and liquidity of the seawater, and because it has a weak ability to resist natural disasters and adapt to changes in natural conditions, the output of the sea farming is far less than thatThe output of freshwater.However, shellfish seawater breeding is far beyond fresh water. Wang Yamin introduced that shellfish breeding places are generally closer to the coast, which is relatively easy to control, so the production of shellfish seawater breeding is relatively large.

my country’s seawater breeding technology is developing rapidly and is gradually catching up with other countries!

In recent decades, China’s seawater breeding technology is developing rapidly.Although some Western countries have been leading in this field, they have gradually been surpassed by our country.

If there is demand, there is motivation for development.Wang Yamin introduced that my country’s population is large and economic development is rapid. The people’s demand for seafood is getting greater and greater, and the output of aquatic fishing is far from meeting the needs of the people. Therefore, it is necessary to actively develop seawater breeding technology.

Technical independent accelerate development.Nowadays, in addition to some foreign seafood, most of the breeding technologies of most domestic varieties come from independent research and development.According to Wang Yamin, for example, the more distinctive oyster breeding technology, and the South White -whitening pairs of shrimp breeding technology are basically independently developed by my country.The northern oyster breeding is basically breeding through artificially selected bodies. The three -fold oyster oysters are fat and large, and they look fast.And the breeding technology of South White Prawn has not developed much in our country. Since the introduction, Chinese scientists can not only rely on seawater to breed through the efforts, but even achieve freshwater farming, breaking through the technology of shrimp farming technology.bottleneck.

Of course, there are still some fish with large demand. At present, there is no way for artificial breeding. For example, the difficulty of eel breeding technology is difficult to break through. Therefore, many eels are basically based on fishing natural eel fry.Wang Yamin said: "I hope that in the future, we can break through these difficulties and put the artificially cultivated eel on the table as soon as possible."
