Salmon is a cold-water fish. Living in fresh water and seawater, it is a kind of anadromous fish. Salmon is a cold-water migratory fish that lays eggs upstream. They originally lived in the northern Pacific Ocean and lived in the ocean for 3-5 years before migrating in groups in summer or autumn.

According to the upstream time, it can be divided into summer biota and autumn biota, and only autumn biota enters Heilongjiang in China. Most of them lay eggs in the downstream, and only a few of them reach the upstream to lay eggs. They go upstream day and night, working tirelessly, and can advance 30-35 kilometers every day and night. No matter whether they encounter shallow canyons or rapids, they don't flinch and rush through many obstacles until they reach their destination.
