Why do you migrate?

They grow up in the fresh water of rivers, but in the seawater of the Pacific Ocean. Generally, it takes 4 weeks to 6 years to reach sexual maturity. Adult salmon eggs can only hatch and survive in fresh water areas, so they have to abandon the sea and go back to the river every autumn (August 11October) or spring (March 1-May near the Arctic Ocean) to lay eggs and breed their offspring.

How to reflow?

Salmon have been on the run all their lives, and they have to go through two long voyages several meters away from Qian Qian. Along the way, they will consume all the fat accumulated in the ocean, and even need to convert muscle fibers into energy to support themselves to swim back to their hometown. When they enter fresh water, the kidneys and other organs of salmon must be adjusted to adapt to the change from seawater to fresh water, so they stop eating or even drinking water, and use the energy stored in their bodies to swim back to fresh water, their birthplace. They will cross waterfalls, and in the process, they will not only face water, but also meet black bears, brown bears, birds in the forest, fishing humans and so on.

What is the meaning of migration?

The parent of the dead salmon rots and decomposes, releasing the nutrients accumulated when living in the ocean, and nourishing the forests and many lives in the basin through rivers and streams at all levels. Therefore, the salmon is the center of the "life network" of the river basin, and brings the nutrients such as nitrogen and phosphorus in the ocean to the forests in the upper reaches of the distant basin. Research shows that 80% of nitrogen is in the forests along the northwest Pacific.

The ecological significance of salmon migration goes far beyond the simple racial reproduction itself. Don't underestimate every species, even those humble creatures. They all have the meaning of existence in the natural life network.

What are the spirits of salmon worth learning?

1. Love your hometown and never forget it.

Salmon was born in the river, grew up in the sea, returned to its birthplace as an adult, bred and died. Heilongjiang and Wusuli rivers are their birthplaces, and the North Pacific Ocean is where they grew up. It takes more than four years for them to grow up from cubs to adults, but no matter how the years pass, they can't kill their will to find their roots, and they can't change their heart of loving their hometown and homeland.

2. Forget yourself and persist in the spirit of seeking

As soon as the salmon grows up, it resolutely leaves the free and comfortable sea and goes upstream without hesitation. They are ambitious and persistent, and they will never stop until they reach their goals; They ignore themselves in the face of difficulties and dangers, and regard death as life, although they die without regret; With firm ideals and beliefs, they explore and advance in the confused journey until they use up the last strength of their lives.

3. The spirit of unity, friendship and mutual cooperation

As soon as the salmon was born, it swam to the sea in groups and lived a collective life in the ocean. When returning to swim, it is even more an order to set off in groups. Before the return of the fish (about a month), three or five groups of "scouts" set out first to detect the flood and transmit information; When a large group of people set out, a generally strong male fish always "leads the way to explore the water" and "clears the obstacles and pushes out stones", and some brave and flexible male fish shuttled back and forth from time to time to serve as guards. The whole school of fish chased after each other and cooperated with each other very tacitly. Where you passed, you were either a tricky "Loach, Turtle, Catfish, Aojiang" or a brave and ferocious "Zhe Dog, Sturgeon".

4. Perseverance and indomitable spirit

I don't know how many life-and-death struggles salmon has experienced in its life. From the North Pacific Ocean to the Black and Ukrainian rivers separated by Wan Li, salmon should break through the barriers of rapids and rapids; We must fight against the attacks of the bear badger falcon again and again; There are countless choices to go back and forth. They never lose heart and never retreat in the face of difficulties. They always embody the spirit of tenacious struggle and perseverance.

5. The spirit of not asking for anything in return and being willing to give.

Salmon is full of treasures, so it can be said that it has dedicated itself to mankind. Its meat is delicious and nutritious. You can make meatballs, wrap them in jiaozi, fry them, steam and marinate them, and everything can be done. Fish liver and fish white can not only be eaten, but also be extracted from protamine to make tonic. Fish eggs are big and bright, and seven are worth the nutrition of an egg. Even fish skin, after frying, is also a special banquet dish. Fish body and roe not only have edible value, but also have considerable economic value, which is a hot commodity to earn foreign exchange through export. Salmon bring so many benefits to human beings, but they never ask for anything from human beings.
