Chinook salmon

Chinook salmon (known by its scientific name as Oncorhynchus tshawytscha) is the largest species out of the Pacific salmon genus, with an individual chinook measured over 120 pounds (fishwatch.gov, 2014). Often known by the name as “king salmon”, it is one of the most expensive salmons as this species of the Pacific salmon is not abundant in North America. This salmon is originated in rivers ranging from Central California to northwest Alaska, but can also be found outside the United States such

that is in serious risk of becoming extinct. This name became connected with the Chinook salmon (Oncorhynchus tshawytscha) in 1994 after being petitioned to be put on the list for nine years (NOAA). There are two main reasons behind the endangerment of the Chinook salmon: over exploration, and dams. Since the times of the Native Americans, Chinook salmon have been highly sought after as a food source. Since then the salmon have experienced great amounts of overfishing. Along with water demands which

their length and weight recorded every week. The premise of this approach was that the muscle 13C would provide information about the source of carbon fueling the juvenile Chinook salmon muscle growth if they remained in each site long enough to reflect local food sources rather than hatchery fish feed products. As Chinook salmon are anadromous fish, the carbon isotope ratios of juvenile muscle tissues are influenced by maternal sources enriched in marine-based isotopes ratios relative to most freshwater

The lifecycle of the New-Zealand chinook salmon is conventional to that of salmon in the North Pacific. chinook salmon (Otherwise known as quinnat or king salmon) mature in the ocean, they typically will reach sexual maturity at 3 years old, but this can vary anything between 2-7 years. (Females take longer than males.) Upon reaching sexual maturity, they will migrate upstream to spawn. Spawning usually occurs in autumn, immediately after all adults die, as the energy expenditure of the process is

Pacific there are five species of salmon. Each kind of salmon is known by different names like, Chinook (king), sockeye (red), coho (silver), chum (dog), and pink (humpback). These are all valuable, but the Chinook or King Salmon were the prize of the Columbia River system. In the late 1800s about 2,500,000 cans of salmon nearly filled a cannery store and storage rooms in Astoria, Oregon. Fresh, salted, dried, and smoked were the only options for preserving and eating salmon before the spread of canning

resulting in a major depletion of salmon species unique to the Northwest. Little’s Report aimed to bring attention to over consumption of this finite resource that was not only intrinsically valuable to many people within the region but was also a very successful economic engine too value to deplete. The booming fishing industry,

low concentration through a selective permeable membrane. Homeostasis operates to regulate the internal conditions of Chinook salmon, it maintains and stable the internal environmental system to ensure the metabolic process and functional organs of salmon are in ideal condition to work efficiently and therefore Chinook salmons have more chances of survival. To make sure salmon remain healthy and the rate of survival also stay same, the homeostatic are necessary for the salmon’s body to make their

The Chinook Salmon or Oncorhynchus tshawytscha is one of my chosen vertebrates, the Chinook Salmon are found natively in the Pacific Ocean, they are anadromous meaning they are born in fresh water, they move gradually move to deep salt water oceans when they are young before returning back to the fresh water streams where they hatched as fully matured adults to lay eggs and die. Chinook Salmon live in water, which has a low concentration of oxygen, this means that for a Chinook Salmon to get its

growth hormone gene that the Chinook salmon is naturally born with. AquAdvantage is currently working on getting their genetically engineered transgenic salmon FDA approved. Their scientists have been able to make the common Atlantic salmon be able to grow to over twice its natural size by inserting the growth hormone gene from the Chinook salmon into the Atlantic salmon, however, there are wider implications to take into consideration before making these transgenic salmon mainstream.

In the California Central Valley, fall‐run juvenile Chinook salmon rear typically from January to June. However, in some years, the rearing period may be reduced due to high water temperatures in April. Growth and survival rates of juvenile Chinook salmon are affected by water temperature and cover (e.g., substrate pore spaces, gravel interstices, boulders, snags, over‐hanging vegetation, root wads, under‐cut banks, and macrophytes). Cover is important for protection from predation, flow displacement
