Salmon species residing in or migrating through the Puget Sound to spawning streams include Chum (O. keta), Coho (O. kisutch), Chinook (O. tshawytscha), Sockeye (O. nerka), and Pink salmon (O. gorbuscha). Pacific salmon require freshwater rivers for spawning and most major tributaries of the Puget Sound have salmon, steelhead and cutthroat ...
Oncorhynchus is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and ...
Competition between juvenile salmon entering the ocean, other wild salmon, and hatchery-released salmon in the ocean is a major factor that determines survival rates. [6] Hatchery production has increased since 1970, and there is high spatial and trophic, dietary overlap between wild and hatchery sockeye, pink and chum salmon in the North ...
The high and low flows of the rivers will be shifted in the seasons, negatively affecting salmon rearing. Increases in water temperatures could affect the food for fish in rivers, lakes, Puget Sound and coastal ocean regions. [38] Fishing is big business in the Pacific Northwest and many local economies depend on fishing.
Graph showing ocean temperature versus depth on the vertical axis. The graph shows several thermoclines (or thermal layers) based on seasons and latitude. The temperature at zero depth is the sea surface temperature. The ocean temperature plays a crucial role in the global climate system, ocean currents and for marine habitats.
The Pacific Northwest is a diverse geographic region, dominated by several mountain ranges, including the Coast Mountains, the Cascade Range, the Olympic Mountains, the Columbia Mountains, and the Rocky Mountains. The highest peak in the Pacific Northwest is Mount Rainier, in the Washington Cascades, at 14,410 feet (4,392 m).
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
