Sockeye salmon is a species of pacific salmon belonging to the family Salmonidae. They are also known by their common name red salmon and blueback salmon.
Sockeye salmon are anadromous species which means they migrate from ocean to freshwater to spawn or breed. Although kokanee salmon, a type of landlocked salmon, do not migrate to the ocean and stay in the same freshwater lake throughout their life. They belong to the aquatic habitat consisting of rivers, lakes, and oceans.
Sockeye salmon return to freshwater streams during spawning. The females usually build nests called redds where they hatch around 45 - 200 eggs.
The sockeye has a bluish back with silver color on its body when living in the ocean and also on the migrating phase and hence the blueback name. They turn red and their heads become green in color to attract mates during breeding seasons.
According to the Internation Union for Conservation of Nature or IUCN Red List, sockeye salmon are listed as species of Least Concern.
Although habitat loss and climate change are some major threats faced by the sockeye salmon. To learn more fascinating facts about sockeye salmon, keep reading.

How do they reproduce?
After growing in the ocean for three to five years, adult sockeye salmon return to freshwater to spawn. Sockeye salmons stop eating after returning to the breeding ground and conserve all their energy for reproduction.
During the process of reproduction or spawning, the largest male becomes more dominant over other smaller males and thus exhibits social hierarchy. The females are involved in building nests known as redds in the spawning grounds.
Fertilization is internal and eggs stay in the redds for some days. The female lays between 50 - 200 eggs in the redd.
Their body changes its color from the bluish back with silver sides to red and their heads become green to attract mates. The eggs take a span of six to nine weeks to hatch.
The females take part in the rearing process of the young sockeye known as fry. The fry is reared for one to three years.
They live in freshwater as juveniles and move to the ocean once they are able to survive and feed on their own. After spawning adult sockeye salmon usually die.
What is their conservation status?
According to the Internation Union for Conservation of Nature or IUCN Red List, sockeye salmons are listed as species of Least Concern. But some of the threats encountered by them include blocked access to the breeding ground, destruction of habitat due to mining and construction of the dams, overfishing, and change in climatic conditions.
The sockeye salmon populations in the United States are listed under the Endangered Species Act.
