In our impression, there are two kinds of fish, one is freshwater fish, which swims in various rivers and lakes, and the other is marine fish, which swim in the blue ocean. The well water of these two species of fish does not violate the river water, but can only be in the waters of their respective environments, because once they cross the waters, they are difficult to adapt to the new environment, so they cannot survive.

But there is such a fish, when it is small, it is born in the river, but it has to swim into the ocean to grow up, and when it reaches the mating period, it will return to the river to spawn and end its life.
This fish is the more popular - "salmon".

The scientific name of salmon in China is called salmon, In North America it is called Chum Salmon, in Japan it is called 鮭 (サケ), and in Russia it is called Кета. Salmon are Pacific salmon in the salmon family, a member of the salmon family, and the most widely distributed of salmon.
Of course, the most classic salmon in the world of salmon is still the "Atlantic salmon", also known as Norwegian salmon. Why is salmon called salmon? With the development of the times, the aquaculture industry of Atlantic salmon has gradually risen, so Atlantic salmon has been sold to the north and south of the world, when this Atlantic salmon was introduced to Hong Kong, "salmon" was translated as salmon, of course, there is another saying is because of the Atlantic salmon fish fat formed by the stripes, so it is called "salmon (stripe) fish".
Slowly the salmon farming industry also gradually rises, because of the wide distribution, the salmon is the Pacific salmon slowly seized the Atlantic salmon business market, and the merchants who sell those salmon are very shrewd, they also use the name of salmon to name salmon, so that it can sell better, so the salmon market began to mix.
Of course, maybe I'm more earthy, I can't eat salmon sashimi this kind of food, I think the taste is very strange, and in 2020, humans should not have evolved to eat cooked food instead of raw food?

Salmon are cold-water anthropocene spawning migratory fish, and every year from late October to mid-November, salmon produce their offspring in the river. When the eggs hatch, these salmon fry will flow along the river and eventually join the river into the sea and then survive in the sea. Of course, it is inevitable that the laws of nature will be eliminated, after all, luck is also part of strength.
After about 3-5 years of living in the sea and reaching sexual maturity, salmon will start their own journey of life. They travel in groups back to their birthplace. Once it enters the mating period, the body surface of the salmon will turn red, which means that it can begin to mate and complete the task of reproduction.
The process of tracing is not easy, it can even be said to be very dangerous, not only to swim against the water to jump the dragon gate of carp, but also in the process there are a variety of speculators, they will intercept and forage on the only way for salmon, after all, there is not much chance of food delivered to the mouth!
After experiencing many difficulties and obstacles, salmon will swim to the most upstream waters, their choice of mating waters can be described as very harsh, if they are not satisfied, they will continue to move forward, upwards until they come to a satisfactory water.
The waters that these strict salmon can choose from:
First, it must be very secluded, so as to ensure that the salmon are not disturbed during the mating process and can leave a safer environment for future generations.
Second, the water quality must be very clear, the water to the clear is no fish, salmon not only for the water quality requirements are very high, in the clear waters there are no other fish, so that their offspring are more likely to survive in the environment.
Third, the water flow is relatively turbulent, the water flow is generally located in the upper reaches of the water flow, where the eggs are laid, the safety of the eggs is higher, and fewer animals will be active upstream of the rapid water flow.
Fourth, the substrate is gravel, and most fish will lay their eggs between the stone crevices, which is conducive to the hatching of the eggs. But the salmon are more comprehensive, they will dig a nest out of the gravel during mating, and then lay eggs in it, after spawning, the female salmon will use the tail to sweep the gravel to fly, covering the eggs produced, making it difficult for other animals to detect.
Of course, the reason why this trip is called the journey of life is because the salmon are very fat when they start from the sea, in this journey of life they can be said to have exhausted their full strength, there is no time to replenish on the road, day and night, tireless, long-distance trek, every day and night forward 30-35 kilometers, such a journey completely consumes the vitality, the original fat body has become thin and sickly, the jaws have become hooked inward, and the large and long teeth are exposed. Finally, after mating was completed, he finally exhausted and withered in the mating waters.
After withering, it becomes the nourishment of other animals, and some continue to turn into spring mud to protect flowers and nourish future generations.
< h1 class="pgc-h-arrow-right" > concluding remarks</h1>
I have to say that life is really wonderful, especially the spirit of salmon that dedicates itself to future generations. Salmon as a valuable fish, it is rich in nutritional value is very high, there is a very high economic value, delicious meat, especially its meat also contains astaxanthin, so the effect of nature need not say more!
Fish, I think it's still cooked delicious!
