Sockeye salmon

Spawning sockeye salmon
A male and female sockeye salmon spawning in the Adams River of British Columbia Canada, in October, 2014. The physical and colour changes the fish undergo while spawning is very evident here. They turn from a silver grey to bright red bodies with yellow green heads. The mouth area turns towards black. In an example of sexual dimorphism, the males grow a large hooked beak and hump in the middle of their back. The females outward appearance changes little aside from the colouration.

Sockeye salmon (Oncorhynchus nerka), also called red salmon, kokanee salmon, or blueback salmon, is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can grow up to 84 cm in length and weigh 2.3 to 7 kg. Juveniles remain in freshwater until they are ready to migrate to the ocean, over distances of up to 1,600 km. Their diet consists primarily of zooplankton. Sockeye salmon are semelparous, dying after they spawn. Some populations, referred to as kokanee, do not migrate to the ocean and live their entire lives in fresh water.
