There are at least 253 identified species of fish known to inhabit the marine and brackish regions of the Salish Sea. Species are listed by common name, scientific name, typical occurrence within the Salish Seas regions. [1]
Salish Sea regions: JF=Strait of Juan de Fuca; SJ=San Juan Islands; BB=Bellingham Bay; SG=southern Strait of Georgia; NG=northern Strait of Georgia; NS=northern Puget Sound; SS=southern Puget Sound; HC=Hood Canal.
Puget Sound is a complex estuarine system of interconnected marine waterways and basins located on the northwest coast of the U.S. state of Washington. As a part of the Salish Sea, the sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel.
Yaquina Bay is a coastal estuarine community found in Newport, Oregon. Yaquina Bay is a semi-enclosed body of water, approximately 8 km2 (3.2 mi2) in area, with free connection to the Pacific Ocean, but also diluted with freshwater from the Yaquina River land drainage. The Bay is traversed by the Yaquina Bay Bridge.
The Mad River is a river in upper Northern California. It flows for 113 miles (182 km) in a roughly northwest direction through Trinity County and then Humboldt County, draining a 497-square-mile (1,290 km2) watershed into the Pacific Ocean north of the town of Arcata near [California Redwood Coast-Humboldt County Airport] in McKinleyville. The river's headwaters are in the Coast Range near South Kelsey Ridge.
The Big River is a 41.7-mile-long (67.1 km) river in Mendocino County, California, that flows from the northern California Coast Range to the Pacific Ocean at Mendocino, Mendocino County, California. From the mouth, brackish waters extend 8 miles (13 km) upstream, forming the longest undeveloped estuary in the state.
Vehicle registration plates in Luxembourg bear a maximum of six characters. The standard series in use today uses a format of two letters followed by four digits. Before adoption of the current scheme, marks consisting only of digits and two digits and three numbers letters, were issued. The digit-only plates may only now be issued as a custom plate.
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of 21,960,000 km2 (8,480,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific, Atlantic and Indian oceans, and larger than the Arctic Ocean.
Fish fulfill several criteria proposed as indicating that non-human animals experience pain. These fulfilled criteria include a suitable nervous system and sensory receptors, opioid receptors and reduced responses to noxious stimuli when given analgesics and local anaesthetics, physiological changes to noxious stimuli, displaying protective motor reactions, exhibiting avoidance learning and making trade-offs between noxious stimulus avoidance and other motivational requirements.
The harborseal, also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. The most widely distributed species of pinniped, they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic and North seas.
Fish are exposed to large oxygen fluctuations in their aquatic environment since the inherent properties of water can result in marked spatial and temporal differences in the concentration of oxygen. Fish respond to hypoxia with varied behavioral, physiological, and cellular responses to maintain homeostasis and organism function in an oxygen-depleted environment. The biggest challenge fish face when exposed to low oxygen conditions is maintaining metabolic energy balance, as 95% of the oxygen consumed by fish is used for ATP production releasing the chemical energy of nutrients through the mitochondrial electron transport chain. Therefore, hypoxia survival requires a coordinated response to secure more oxygen from the depleted environment and counteract the metabolic consequences of decreased ATP production at the mitochondria.
Tail codes on the U.S. Navy aircraft are the markings that help to identify the aircraft's unit and/or base assignment. These codes comprise one or two letters or digits painted on both sides of the vertical stabilizer, on the top right and on the bottom left wings near the tip. Although located both on the vertical stabilizer and the wings from their inception in July 1945, these identification markings are commonly referred as tail codes. It is important to note that tail codes are meant to identify units and assignments, not individual aircraft. For all aircraft of the U.S. Navy and U.S. Marine Corps unique identification is provided by bureau numbers.
Allochronic speciation is a form of speciation arising from reproductive isolation that occurs due to a change in breeding time that reduces or eliminates gene flow between two populations of a species. The term allochrony is used to describe the general ecological phenomenon of the differences in phenology that arise between two or more species—speciation caused by allochrony is effectively allochronic speciation.
