'''Sockeye salmon''' (''Oncorhynchus nerka''), also known as '''red salmon''', '''kokanee salmon''', or '''blueback salmon''', is a species of [[anadromous]] fish in the [[salmon]] family. It is primarily found in the northern Pacific Ocean and rivers discharging into it. | |||

Species of fish
Sockeye salmon (Oncorhynchus nerka), also known as red salmon, kokanee salmon, or blueback salmon, is a species of anadromous fish in the salmon family. It is primarily found in the northern Pacific Ocean and rivers discharging into it.
Description[edit]
Sockeye salmon are distinguished by their bright red bodies and green heads during spawning. They are smaller than some other salmon species, typically weighing between 2.3 to 7 kg (5 to 15 lbs) and measuring 60 to 84 cm (24 to 33 inches) in length. The species is known for its striking color change from a silvery blue while in the ocean to a vibrant red when spawning.
Distribution and Habitat[edit]
Sockeye salmon are native to the northern Pacific Ocean and the rivers that flow into it. They are found from the Columbia River in the United States to the Anadyr River in Russia. The species is also present in the Bering Sea and the Sea of Japan.
Life Cycle[edit]
Sockeye salmon are anadromous, meaning they migrate from the ocean to freshwater to spawn. They are born in freshwater lakes and rivers, where they spend one to three years before migrating to the ocean. After one to four years in the ocean, they return to their natal freshwater habitats to spawn and die.

In the ocean, sockeye salmon primarily feed on zooplankton, small fish, and squid. In freshwater, juveniles feed on plankton and insects.
Conservation[edit]
Sockeye salmon populations are affected by habitat loss, overfishing, and climate change. Conservation efforts focus on habitat restoration, sustainable fishing practices, and monitoring of populations.
Cultural Significance[edit]
Sockeye salmon hold significant cultural and economic importance for indigenous peoples and commercial fisheries in the Pacific Northwest. They are a vital food source and are celebrated in various cultural traditions.
Commercial Fishing[edit]
