Why I Chose This Topic
I chose this topic because of the infamous “salmon run” that salmon go on. It is cool that they are able to travel thousands of miles away and still know their exact birthplace to return to. I also love eating salmon too, I add lemon pepper seasoning on it and then cook it. |

Science Concept
The upriver salmon migration is one among nature's exciting events. However, to the 5 species of Pacific salmon (Chinook , chum, coho, red, and sockeye), its miles are a strenuous race against time, with every obstacle taking a toll on their body.
Pacific salmon belong to a group known as anadromous fish that includes Atlantic salmon, sturgeon, lampreys, shad, herring, sea-run cutthroat trout, and steelhead trout. These species hatch and stay the first part of their lives in freshwater, then migrate to the sea to spend their adult lives, which can be as brief as 6 months or as long as 7 years. After they attain sexual adulthood, they go back to the freshwater stream of their birth to lay their eggs. Pacific salmon make the round ride most effective once, however some Atlantic salmon may additionally repeat the cycle numerous times.
Migration among fresh and salt water takes place for the duration of every season of the year, relying on latitude and genetic traits of the fish. Groups of fish that migrate collectively are known as runs. Salmon spawn in nearly all freshwater habitat, from intertidal areas to high mountain streams. Some Pacific salmon may swim thousands of miles to get back to the stream that they hatched. However, usually a small percent of salmon stay to attain their natal stream or spawning grounds.
The adult males that stay alive after the trip are often gaunt. They have grotesquely humped backs, hooked jaws, and torn fins. The females are swollen with a pound or greater of eggs. Each has massive white patches of bruised skin on their backs and aspects. After this Salmon run, they usually give birth, and die immediately. Thus is the life cycle of a Salmon, a complicated, tiring, hard working fish that tastes SO good.

Application
Salmon is a critically important species with significant ecological, economic, cultural, and scientific value. These are some reasons why studying salmon is essential for a variety of reasons.
From an ecological view, salmon are a keystone species that plays a critical role in maintaining the health and stability of many ecosystems. Salmon are an important food source for a wide range of predators, and their carcasses provide nutrients to both terrestrial and aquatic ecosystems, making them important in nutrient cycling. By studying salmon, we can gain a better understanding of their interactions with other species and the role they play in ecosystem dynamics, which is critical for managing and conserving ecosystems effectively.
From an economic perspective, salmon is an important commercial and recreational fishery species that generates billions of dollars in revenue every year. Many communities and businesses rely on salmon for their livelihoods, and managing salmon fisheries is essential for supporting the economy and protecting the species from over-development. By studying salmon, we can better understand their life cycle, distribution, and behavior, which can inform management strategies and help ensure that this valuable resource is available for generations to come.
Salmon also have significant cultural importance, particularly for Indigenous peoples who have relied on them for food, trade, and cultural practices for thousands of years. Salmon is considered a sacred animal and is celebrated in arts, dance, and ceremonies. By studying salmon, we can better understand their cultural significance and support efforts to conserve and protect them.
Lastly, salmon also have significant scientific value, as they have a unique biology and life cycle that is still not fully understood. For example, salmon have an extraordinary ability to navigate using magnetic fields, and their sense of smell allows them to locate their natal streams from thousands of miles away in the open ocean. By studying salmon, we can gain insights into a range of biological and ecological processes, including migration, reproduction, and adaptation to changing environmental conditions, which can inform broader scientific research.
In summary, studying salmon is crucial for understanding their ecological, economic, cultural, and scientific significance, and for informing conservation and management efforts that can help ensure the sustainability of this important species.

Famous Scientist
Meriwither Lewis and William Clark are the first finders of salmon in the US on their expedition during the early 1800’s. On August 13, 1805, at a camp of Lemhi Shoshone Indians in the mountains of present-day central Idaho, Lewis wrote, “An Indian gave me a piece of fresh salmon roasted, which I ate with a very good relish. This was the first salmon I had seen, and it perfectly convinced me we were in the waters of the Pacific Ocean.” The explorers would record other observations of Lemhi salmon. Clark noted that salmon was a principal food for the Indians: “...one man killed a Small Salmon, and the Indians gave me another which afforded us a Sleight breakfast. These poor people are here depending on what fish they can catch, without anything else to depend on.”

Career Path
Fish biologists at the Department of the Interior preserve, conserve, propagate, and manage the populations and habitats of fish and other aquatic species. The ideal candidate is able to apply and communicate their scientific knowledge with a wide variety of people with varying levels of technical knowledge. They must have an ability and desire to learn how to use specialized equipment, be able to plan and conduct complex projects, analyze data, and manage program
