The ancestors of salmon originally lived in rivers in cold regions, but there was a lack of food. In order to feed and reproduce, they had to swim down the river to feed and grow in the ocean. As their bodies grew up and matured, they had to return to their hometown to raise children, because young salmon could not be separated from their hometown.

Their swimming speed is very fast, and it is feasible to swim up the river for 40 kilometers every day and night. Its embryonic development period is very long, and it takes 3 ~ 4 months for small fish to hatch from the egg membrane.

The small fish just hatched is about 2 cm, and the residual yolk is still dragged under the stomach to provide nutrition for its continued development. When they grow to about 4 cm, they leave their hatcheries and go to the nearby water to feed on small animals, and sometimes the bodies of their parents will become their food.

Extended information salmon is also called salmon.

Salmon contains a substance that can significantly enhance its physical strength-astaxanthin. According to scientific reports, wild salmon contains 5mg of natural astaxanthin per kilogram of salmon meat, and cultured salmon is white if astaxanthin is not used. This astaxanthin is the reason why salmon has strong physical strength.

Because astaxanthin is the strongest antioxidant found so far, Eskimos who eat salmon for a long time basically have no heart disease, diabetes, arteriosclerosis, etc., and their physical strength is super strong. The collagen content of Arctic salmon gelatin is the highest among all fish, and its gelatin is easily absorbed by human body, so it is a beauty product with high cost performance.
