Knowra Oncorhynchus Oncorhynchus Oncorhynchus is a genus of salmonid fishes native to the North Pacific and its tributary waters. It includes Pacific salmon, rainbow trout, and cutthroat trout.
Salmonidae : Salmonidae is the family of ray-finned fishes that includes salmon, trout, char, and grayling. Oncorhynchus is one of the family's major genera.
Chinook salmon : Chinook salmon is the largest Pacific salmon species, native to the North Pacific and its tributaries. It is a large-bodied Oncorhynchus species with both ocean-going and resident populations.
Natal homing : Natal homing is the tendency of an animal to return to its birthplace to reproduce. Many salmonids return to their home stream, helping maintain distinct Oncorhynchus populations.
Pacific salmon fisheries : Pacific salmon fisheries harvest migratory salmon in rivers and coastal or offshore waters. Commercial, subsistence, and recreational harvests rely on multiple Oncorhynchus species.
Salmo : Salmo is a genus of salmonids that includes Atlantic salmon and brown trout. It is a closely related salmonid genus, but its native range centers on the Atlantic and Eurasia.
Anadromy : Anadromy is a life history in which fish migrate from the sea into fresh water to reproduce. Many Oncorhynchus species hatch in fresh water, grow at sea, then return to spawn.
Sockeye salmon : Sockeye salmon is a Pacific salmon species known for spawning migrations to lakes and its red breeding coloration. Its frequent dependence on lakes illustrates a distinctive Oncorhynchus life history.
Olfactory imprinting : Olfactory imprinting is the learning of chemical cues that later guide an animal to a familiar location. Salmon use learned stream odors as part of their return migration.
Salmon cannery : A salmon cannery is an industrial facility that processes and preserves harvested salmon. Canneries expanded commercial exploitation of Oncorhynchus runs along the Pacific coast.
Salvelinus : Salvelinus is a salmonid genus that includes chars such as Arctic char and brook trout. Its chars are close relatives, not members of Oncorhynchus.
