What is the salmon that people all over the world love? Maybe people really don't know. The word salmon comes from Latin Salmo, which means jumping. A long time ago, there was a fish in the North Atlantic that swam from the sea to the river every year to lay eggs. These fish struggled to jump over waterfalls and go upstream during their migration, hence the name.
This is the upstream migration in biology. The so-called "upstream migration" refers to the behavior of fish laying eggs in freshwater rivers, swimming to the sea after birth, and then migrating to rivers to breed when they are sexually mature. Similar behaviors include spawning in the sea, swimming in fresh water after birth, and migrating to the sea to breed after sexual maturity, which we call "migration to the sea."
/kloc-in the 0/8th century, Linnai, the founder of biological nomenclature, gave the word Salmo to this delicious fish from the North Atlantic. However, when European colonists crossed the North American continent and arrived at the Pacific coast, they were surprised to find that there were also many kinds of fish that looked like Salmo and would migrate and lay eggs.
In order to distinguish them from their relatives in the Atlantic, people call them Atlantic? Atlantic Salmo? And call the latter? Pacific Salmo? . Salmon in a broad sense has also become a general term for salmon and trout with upstream migration (excluding trout in fresh water).
This kind of fish will also appear in the rivers near the North Pacific Ocean in Northeast China. However, it already has a Chinese name. Salmon, or salmon, actually belongs to the Pacific Salmon, which is called Pacific Salmon in Chinese. The corresponding Atlantic Salmo is called Atlantic salmon.
At the beginning of the 20th century, Atlantic salmon was a very important fishing target, and its output increased year by year. Artificial aquaculture started to become an important seafood pillar in Europe and North America, and gradually began to occupy the world market. In order to let Atlantic salmon occupy the market of Pacific salmon, businessmen began to speculate on the word Salmo, replacing Pacific salmon with salmon, which complicated the market for salmon.
After telling so many stories about salmon, are you already confused? Congratulations, you have also become the target of successful business speculation. To sum up briefly, salmon in a broad sense refers to all salmon and trout with anadromous migration under all salmonidae; Salmon in a narrow sense, due to the historical reasons mentioned above, only refers to Atlantic salmon belonging to Atlantic salmon, namely SalmonSalar.
Now the salmon market is mixed, and it is really difficult to distinguish the real salmon. However, salmon sashimi has always been loved by people all over the world, and eating raw salmon has become a symbol of quality life. The accompanying fish parasites have also become the object of criticism. So, are there really many parasites in salmon?
However, about 95% of Atlantic salmon currently sold in China market comes from Norway. As the world's largest producer of Atlantic salmon, China imports more than/kloc-0.5 million tons of Norwegian salmon every year. It belongs to the cold northern Europe, and numerous deep fjords with clear water quality and cold environment are excellent conditions for salmon growth.
Salmon parasites living in such cold, pollution-free deep water are rare. In addition, salmon imported through formal channels are subject to national import and export quarantine, and generally there will be no parasites. But some fake salmon on the market, scientific name? Rainbow trout? This kind of fish itself is in fresh water, and the parasites are really complicated, so it is generally not suitable for raw food.
