Salmon are in huge demand all over the world. In 2014, over 146,000 were caught statewide. Even though it may seem as though catching all of these salmon will cause them to go endangered, they still thrive. There are many ways that humans also contribute to keeping the salmon population high. We raise them ourselves and also help out the ones in the wild. One of the ways we do this is by creating fish ladders. Fish ladders are like stairs underwater that fish like salmon can use to get over an obstacle that is in the way. Salmon can travel up to 1,000 miles and can not be stopped by different things such as water falls for dams. These ladders have helped them out tremendously.
Even though we may only think salmon are for eating, this is not the case. Many other species that live in the ocean also rely on salmon. By making them go extinct, we are not only effecting ourselves, but also an entire ecosystem. All animals from bear, to birds, to other fish feed on salmon. Beaver and salmon also work together in the natural ecosystem. Beaver's dams provide proper shelter for baby salmon and salmon provide good nutrients for the water around the dam.
Salmon may be abundant in some regions, but in others, they can become quite scarce. Salmon fishing in the Atlantic has dropped in quantity lately because of

They take is extremely seriously and have strict laws that every fishery must follow in order to continue to operate. It is even written in their constitution that "fish…be utilized, developed, and maintained on the sustained yield principle." (A Sustainable Catch) Some people may wonder who is in charge of making sure that the salmon population is treated with care. The answer for that is everyone. Everyone from state to international organizations reinforce the laws that have been created. They also come together to create laws, and determine things like, how many salmon can be caught that year without damaging the
In the past, because the glaciers disappeared slowly can make people have a low temperature, clean water during the summer, but at the same time the salmon begin and end their lives. With temperature getting warmer and our glaciers melting, every stage of salmon’s life cycle is getting hurt.
This loss of salmon life in the river system greatly affected the nutrient levels in the rivers. As stated in the film, the sockeye provided

The salmon are all sterile females which are grown in contained land-based systems, therefore they will not be able to breed among themselves or with other fish. So it is unlikely that the fish will have an impact on wild populations.
In recent years, chum salmon returns have seriously decreased in the Great Bear Rainforest. In the fall of 2009, local people reported that a majority of bears did not return to fall fishing grounds. There is major concern that grizzly bears starved in their dens over the previous winter due to lack of salmon in the feeding season before that.
Through the research done to study genetically engineered salmon, it has been provide that it not good for human consumption. Genetically modified salmon present the higher levels of Insulin-like Growth Hormone are than wild salmon. The higher levels of IGF-1 absorb in humans has shown to increased risk prostate, breast and colon cancers. In addition genetically modified salmon have a lack of nutritional value...
Generation after generation gathered food off the land, people are continuing to practice this in our modern world today. Societies expressly continue to gather their own food as it provides an inexpensive, delightful tasting meal. One of the techniques of our historical past that is still in use today, that has been used for generation after generation is “netting” fish. Netting is a classic technique that has not faced as many revisions to its practice. It persists from one generation to the next due to the fact, that many do not understand it to be harmful to the environment; others may enjoy the idea of letting commercial fisheries catch large numbers of fish as it continues to keep some of Americans favorite meals low cost. Devastating fall out from neglectful thinking about netting will occur in the future if preservative action toward this way of life is not taken. Minimizing the use of nets in waterways will ensure salmon and other fish survive for many more generations to come, allowing this plentiful food source given to us by Mother Nature to be exploited and enjoyed by our future kin. With food sources now readily available, fishing with nets should be reevaluated as follows; who is allowed to fish with nets, what are their purposes, and how will this effect tributary fishing populations.
Due to the demand many packaging for the fish can find its was back to sea, or when fishermen are out at sea they can leave their garbage. Many nets from the boats and gears can also be found in the water, that fish can later see as food, eat it, and die; this ties back to extinction in fish. There is much pollution and decline stocks in fish because it is very hard to regulate the seas. To fulfill the growing demand for seafood, many companies are forced to fish beyond areas that are supposed to be non-fishing zones. This is because there are hardly any laws or restrictions telling them where they can and cannot fish. Sally Driscoll and Tom Warhol report in, ‘Overfishing’, that itt wasn’t until 1956 where we saw our first regulation, the United Nations organized the first UN Convention of the Law of the Sea or the NCLOS which helped promote rights of all countries by establishing boundaries off shore. Meaning that some seafood fished in certain areas of the ocean cannot be sold in certain countries, and in some areas it is illegal to fish unless you have a permit from that country. Economy also helps make it harder to regulate the seas, in ‘Overfishing’ it is explained that Preisdent Barack Obama brought up Antiquities Act of 1906, that let fishermen expand their fishing areas. The United Nations FAO estimates that 25 percent of all fish trapped in nets are labeled unusable or not licensed for fishing by the
The topical focus of this paper is the Atlantic salmon fishery. In particular, this paper looks at habitat loss and salmon farming both of which have had major impacts on the sustainability of the fishery. Several efforts have been made to restore Atlantic salmon to their native habitat, specifically in Maine and New Hampshire. This paper reviews the policies that have been implemented, not yet implemented, and a proposed policy.
Pinkish in color, with spots on their eight fins and back, thin long body with an average weight of 23 kg and length up to 76 cm, and a distinct back fin called the adipose fin. They are saltwater fish which spawns in fresh water, travelling over 20,000 kilometers in the ocean with speeds of up to 50 km per hour. They can jump more than four meters to climb waterfalls and any obstacles they encounter in the water. The Northwest Salmon is one miraculous fish. However, Northwest Salmon are now on the verge of being protected under the Endangered Species Act due to their dramatic decline in their population in the Northwest region of the United States. Their declines in numbers are causing great problems for their surrounding ecosystem, those that rely on the salmon as a food source, and the fishing industry. All of which humans are contributing to all these by overfishing, either commercial or for sport, and the construction of dams on major rivers. Then with the attempt to fix this problem, fisheries, or farms for fish, end up genetically changing the fish and making them more vulnerable to predator fish. Predator fish that are nonindigenous to the rivers the salmon swim in. Eating the salmon’s food or in most cases, eating the salmon themselves. If all of these acts continue at full force, I predict that the Northwest Salmon will not be naturally running up and down our American rivers within the next 50 years if not everyone is totally aware of their situation.
In the last 30 years since the lionfish first appeared in the Atlantic Ocean, they have become a destructive nuisance. The lionfish species which are native to the Pacific Rim and Indian Oceans are now invading the Atlantic and Caribbean Oceans, eating any fish that can fit into it's mouth. Scientists don’t believe the invasion will ever be completely eradicated, however if the problem is recognized there are steps that can be taken to try and contain this invasion at a manageable level. Through education, fishing or hunting of the species and by teaching other species to eat the lionfish, there is hope humans can gain control over these invasive creatures.
Salmon farming began over 30 years ago and has become a huge industry. Experts say it’s the fastest growing segment of agriculture. Salmon farming plays an important role in the economies of many areas as well. Jobs and other economic benefits contribute to the value of salmon as much its role in good nutrition. Salmon is an oily fish rich in omega-3 fatty acids, a substance that almost certainly helps protect against heart disease and may also reduce the risk of cancer and Alzheimer's.
The Coho salmon spends its time in both freshwater and saltwater. In central California, where many Coho salmon rest every winter. Streams like this use to host thousands of Coho salmon each year. Weeks at a time two-to-three foot fish swimming upstream with schools of fish (News Deeply, 2015). Ready for reproduction for the next generation of Coho salmon. With the Coho salmon planning their trip upstream to reproduce. Few of these waterways do not have enough water for the salmon swim upstream and begin their reproduction process. Because of this the Coho salmon are close to extinction. Todd Steiner, Who lives in western of Marin County, sees just a few dozen Coho salmon swimming upstream every year. a director of the Salmon Protection and
Since salmon do not feed once they leave the ocean, some will die on the way because they lack enough stored body fat to make the trip. Many will be caught in fishermen's nets. Those that evade the nets may have to swim through polluted waters near cities. Many must make their way over power dams, leaping up from one tiny pool to the next along cement stairstep cascades called fish ladders. In the tributary streams, waterfalls and rapids are steep and swift enough to eliminate all but the strongest. Otters, eagles, and bears stalk the salmon in shallow riffles. Once on the spawning grounds, the fish battle each other: females against females for places to nest, males against males for available females.
