To produce offspring; if they didn't mate the species would die out.
no as far as i know but i do know that some salmon mate in Alaska
A salmon offspring is when salmons mate and have babies.
Salmon migrate out to sea, and then return to where they were born to mate.
When salmon mate their heads turn green and their bellies pink.
To mate and lay their eggs.
Well since the salmon have enough trouble getting up the stream to mate they might as well make them not have to
Salmon migrate out to sea, and then return to where they were born to mate.
In a way (some) do. Some species of Salmon only breed once, and die shortly after. So yeah, that one time becomes "for Life"
It's instinctual. They go to where the water is warm to mate and lay their eggs
A Pink Salmon habitat are streams, marshes and rivers. The rivers and streams originate from the ocean. When they get older, they go deeper in the water. When they mate, they go on a long journey to go back to their home, and lay eggs there.
Salmon will return to their hatching place to spawn. A single group of salmon may travel hundreds of miles back to the river of their birthplace, hopping over waterfalls, swimming upstream until they get to the place where they hatched. They will then mate and lay eggs, beginning into being another cycle of leaving and returning to spawn. This journey is very dangerous, due to bears waiting at the top of waterfalls to catch the returning salmon.
Salmon migrate in order to reproduce. Salmon live most of their lives in the ocean, but reproduce in rivers. Spawning time depends on the location. When it is time to spawn, the fish swim upriver. Many are caught by predators such as bears and humans. When the salmon reach the spawning grounds, they will mate, lay eggs, and die. After the eggs hatch, the young will swim downriver to the sea. The Copper River in Alaska is famous for salmon. Here is a more detailed article on salmon spawning. http://animals.howstuffworks.com/fish/salmon-info3.htm
