No.
Salmon migrate as part of their lifestyle. They breed upstream in rivers so that their young are safe from the major open-ocean predators and can grow to a proper size. Once they are large enough, they need to go out into the open ocean to find food large enough to sustain them. When they are old enough to breed, they return to upstream rivers in order to lay their eggs and die, starting the cycle all over again. This has no correlation with climate change/global warming.

What is one seasonal change that causes organisms to migrate?
Animals migrate because of changes in weather or local availability of food. This is either an annual change as in bird migration or as part of their life cycle as in Atlantic salmon.
What animals are migratory?
Some examples of migratory animals include birds (such as swallows, geese, and hummingbirds), mammals (such as wildebeest, caribou, and whales), fish (such as salmon and eels), and insects (such as monarch butterflies and dragonflies). These animals travel long distances between breeding and feeding grounds in response to changing seasons or resource availability.
How many Chinook salmon are left in the world?
It is difficult to provide an exact number, but Chinook salmon populations have declined significantly in recent years due to habitat destruction, overfishing, and climate change. Conservation efforts are being made to protect this species and its remaining populations.
Name of the fish which swims against the flow of water?
The fish that swims against the flow of water is called a salmon. They migrate upstream to spawn and their ability to swim against strong currents is due to their strong muscular bodies and specialized physiology.
What are the migrations made by salmon and eels for purposes of reproduction?
Salmon migrate from the ocean to freshwater rivers and streams to spawn, returning to their exact place of birth in a remarkable feat known as anadromy. Eels migrate from freshwater rivers to the ocean to spawn, a process known as catadromy. Both species navigate these challenging journeys to ensure successful reproduction.
Where do salmon migrate?
Salmon migrate out to sea, and then return to where they were born to mate.

How do salmon migrate?
They swim.
Where do salmon?
Salmon migrate out to sea, and then return to where they were born to mate.
Does a salmon's body temperature change when the temperature of its environment changes?
Yes indeed, as they are cold blooded. Research with Chinook salmon has shown that they will cease to migrate upstream when temperatures are above about 23 Celsius.
Where do salmon migrate to?
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

Is salmon a freshwater fish?
Salmon are anadromous fish, meaning they are born in freshwater, migrate to the ocean to mature, and then return to freshwater to spawn. They spend most of their life in the ocean but require freshwater for reproduction.
