According to an expert at California Fish & Game, salmon spawn at the Nimbus Fish Hatchery in mid-Autumn, in the November time frame, provided the rivers are flowing well and the weather is cool enough. Spawning, of course, follows the upstream swim from the Pacific Ocean.

What most directly salmon to swim in a river?
Salmon swim upstream to live out their adult lives. The thing that helps them to swim upstream is purely will power and instinct. They are taught all of their lives to swim to the ocean when they are adults and return to the river where they were born to give birth and die.

Why salmon swim upstream?
It is natural for fish to swim in any direction and and at night time when there is no light from the moon they go into direction in surfaces where artificial light is present. Their biological requirement for oxygen directs them to swim counterflow to the source of current that is normally loaded with high amount of dissolve oxygen .
How do you salmon get through dams?
Most dams have side-runs, fish ladders, tubes or tunnels for salmon to move past the dam. The problem remains that the dam may have flooded the salmon's original breeding grounds. Most dam agencies try to maintain some of the salmon's original breeding habitat. If all of this habitat is destroyed, then those salmon can not reproduce.
What is the unique about salmon move to spawn?
Almost all Salmon swim back to the place they were born themselves to spawn. This requires them to undertake extremely long journey, right up to the stream source where they were born. For reaching there the salmon have to swim upstream ( against the flow of stream), which is quite exhausting for them. Additionally when the salmon swim back for spawning they are hunted enthusiastically by many carnivores like Bears etc. This results in death of many salmon during the journey. When the salmon leave ocean ( where they habit after becoming adults) to go back to freshwater streams to spawn the fish undergoes physical transformation to adapt itself from the saltwater to fresh water conditions. All Pacific ocean salmon die after spawning. Whereas the Atlantic Ocean salmon might return back to ocean after spawning to continue its lifecycle.
What most directly enables salmon to swim in a river?
salamon are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. However, there are rare species that can only survive in fresh water habitats. folklore has it that the fish return to the exact spot where they were born to spawn; tracking studies have shown this to be true but the nature of how this memory works has long been debated.
Salmon What happens to the young salmon.?
If they are farm salmon, they swim around, eat, and grow. If they are land-locked salmon (lake) salmon like silver salmon (kokanee), they swim around, eat, grow, lay eggs, and fertilize them, and tend them. If they are andromedous salmon, the are born in a stream or ocean, sometimes hundreds of miles from the ocean. When they get a couple of years old, or so, they swim downstream, enter the ocean, and eat lots of ocean creatures that make them grow very large, with a rather oily flesh. Some are eaten by ocean animals that love salmon, and the remainder, after several years in the ocean, find the streams of their babyhood and swim up them, sometimes hundreds of miles, to where they were born. Some are eaten by bears or otters, others are caught by fishermen, and some simply die of exhaustion. The ones that make it all the way upstream get together and spawn (lay eggs, fertilize them, tend to the eggs until babies are born.)
Why do fish swim up rivers?
Fish have an organ called a swim bladder. This organ controls exactly where in the water a fish is. Its fins simply propel the fish in a direction. The swim bladder controls the up and down bit.
How do penguins whales and salmon compare?
