Salmon is one of our more common fish, they also have many other names, such as "Luo Guoyu", "Ma Gongyu" and so on.Salmon's life habits are quite special, although they can be said to be marine fish, but they do not always stay in the sea, but change.When salmon are young, they live in the ocean.Because salmon are cold-water fish, they are widely distributed in high latitudes, such as in the North Pacific Ocean, where many salmon are distributed.
However, when the salmon are mature, they will go to fresh water to breed, that is, to migrate upstream.Salmon breeding season is usually in the autumn of each year.Especially from September to October, salmon will come to freshwater rivers, and the number of salmon coming to freshwater is very large every time.They will travel for a long time in groups and will not retreat when they encounter canyons and waterfalls.Generally speaking, male fish are easy to die after reproduction because of too much energy consumption.Some females return to the ocean after breeding.
As mentioned above, when salmon are relatively young, they live in the ocean.They are most abundant in high latitudes because they are cold-water fish and are more suitable for living in cool sea water.However, when the salmon mature, they will face the problem of reproduction.When they breed, they live in fresh water.After breeding, the salmon will return to live in the sea.
