Where does all the salmon on the mainland market now come from?

Salmon and tuna are among the more famous and mass-produced marine fish products on the market. The nutritional value of salmon is very high, not only rich in protein, but also contains high EPA and DHA and other biologically active substances. Salmon belongs to the cold water fish, mainly living in the class of the Arctic Circle in the cold water ocean.

The world's salmon is mainly produced in northern Europe, the northern United States, Japan, Russia, Canada and other countries in the north. Some of our country's waters also have the existence of salmon, only the production is very low. Our main salmon importer is Norway, Norway's salmon production is very high, and even formed a salmon brand in the world? Norway salmon.

Norwegian salmon quality is very high, its crude fat, crude protein content are much higher than the content of salmon in other regions. Salmon is a relatively special fish species, they can swim freely between freshwater and seawater, and its spawning is in the freshwater area. Salmon are schooling fish, feeding and spawning together in schools.

There is a big difference between wild salmon and farmed salmon. Wild salmon is not easy to survive due to the competitive environment, and it usually takes three years to mature, with a lot of muscle and very little fat. The quality of wild salmon is actually not as good as farmed salmon. Farmed salmon originates from Norway, where the world's largest salmon farm is located. Due to the lack of a natural competitive environment, farmed salmon is a safer place to live, and the feed for farmed salmon consists of high protein, the salmon grows very quickly and has a high fat content, while at the same time increasing its protein content, especially in terms of amino acids, which is higher than that of wild salmon.

The demand for salmon in the world market is so great that the countries that farm salmon have taken a different approach and developed another variety? Genetically modified salmon. Scientists use technical means, in the fertilized eggs of Atlantic salmon implanted in the Pacific Chinook salmon growth hormone gene, as well as the ocean cod antifreeze protein gene , ocean cod antifreeze protein can make the transgenic fish in the cold environment to continue to secrete growth hormone, which in turn to achieve the goal of shortening the growth cycle . Such genetically modified salmon has been scientifically certified and tested and approved by the food regulatory authorities, and is now on the market to meet the global salmon market demand.

Since China is a big consumer of salmon, the production of salmon in our waters is very low and most of the salmon on the market needs to be imported.
