General Description

Sockeye salmon" The Red

Sockeye salmon, scientifically classified as Oncorhynchus nerka, belongs to the Salmonidae family. The genus name means “hook snout” in Greek, while nerka originates from a Native American word for the fish. Sockeye are anadromous, hatching in freshwater, migrating to the ocean, and returning to spawn in freshwater.

Life History/Biology

In freshwater, juveniles feed on zooplankton and insects, while adults in the ocean feed on small fish and squid. Their carcasses enrich river ecosystems, providing vital nutrients for new salmon.
