Chinook Salmon
Environmental Science Wednesday, February 26, 1997
Among the many kinds of fish harvested each year by commercial fisheries is the
Oncorhynchus tshawytscha or Chinook salmon. The United States catches an averages of about three hundred million pounds of salmon each year. However some Chinook salmon have been recently listed as threatened. Man has been the main cause for the decline in Chinook salmon populations.
The populations of Chinook salmon have declined for several reasons. Hydropower and it's destructiveness to the environment, pollution, and overfishing are the three main causes for the decline. The Chinook salmon is known for traveling the greatest distance back to its spawning grounds, often traveling one to two thousand miles inland. This long journey is now often interrupted by hydroelectric plants. Hydropower is a very good alternative resource for power, however it is very damaging to our salmon populations. The dams block off rivers, which block the salmon's path back to their breeding grounds. The salmon go back to the same areas, just as their ancestors did, to lay their eggs.
The hydropower plant's turbines are also very dangerous to young salmon. Many of them are killed by the giant turbines on their way back to the ocean.
Killing off many of the salmons new generation. Pollution is also a killer of many Chinook salmon. Pollution caused by sewage, farming, grazing, logging and mining find it's way into our waters. These harmful substances kill many species of fish and other marine life. The Chinook salmon is no exception. The chemicals are dumped into the rivers and streams and eventually these chemicals find their way to the ocean, polluting and effecting each area they pass through.
The largest contributor to the decline in the Chinook salmon population is the commercial fishing industry. From a period of 1990-1992 815,000 Chinook salmon were caught by commercial fisheries. This does not include the 354,000 recreational catches. Commercial fishing is a big industry. Commercial fishers use nets, which they pull by boats. Some nets are designed so the holes in the nets are large enough for the head of the fish to fit through, and then the mesh gets caught in the fish's gills. Others are designed to circle around a school of fish and then is drawn shut. New technologies have developed factory stern trawlers which easily haul netloads of up to 100 metric tons of fish. However, when catching the salmon, fisherman use pound nets to catch the fish on their way to their spawning grounds. The average annual salmon catch in just the
United States is about 300 million pounds, of that about 60 percent is canned.
Policies are often put in place without regards for the effect it will have on other areas, people, or wildlife. Several examples of these unintended consequences are shown in the documentary Salmon: Running the Gauntlet, which explains the effects that human activity, dams, and attempts to repopulate the salmon species have been implemented and failed. With proper evaluation at the onset of a major project, these severe consequences may be avoided.
All fame begins when you do something noticeable. For example, actors and actresses build upon their careers and reputations by achieving excellence in their personal goals, as well as perfecting their public performance.
We are prisoners to our perception. It is a common saying that things are not always as they seem .This philosophy is abundantly true when it comes to the subject of fame, celebrity, furtune and impact. The way we see things is responsible for the set up of our individual ideologies.”Evidence “by Kathryn Schultz refers to ideology as a “conceptual framework” (Schultz, page 373).We see fame as the greatest achievement that one could accomplish in their lifetime. We idolize and fantasize how the wealthy are free of the burdens of life and that they are faced with little to no misfortunes. As pointed out several times throughout this writing, this is a counterfactual way of looking at fame. Schulz’s essay further states that “to exist, to deal with reality, we need a conceptual framework; theories that tell us which questions to ask and which to not, where to look and where not to bother.”(Schulz, page 373).This quote relates to the subject matter because I also feel that individuals tend to overlook the cons of fame and focus too much of the glitz and glamour associated with fame.Basically,some people see what they want to see and ignore what they don't want to accept and
celebrity may be found in the words of one of America’s Founding Fathers, John Adams, who wrote, ‘‘The rewards . . . in this life are steem and admiration of others—the punishments are neglect and contempt. The desire of the esteem of others is as real a want of nature as hunger—and the neglect and contempt of the world as severe as a pain.” (Price, 463). The author suggests that fame is not at all w...
The star text of a celebrity can help to decipher their image and transitions they may undergo. In order to better understand these transitions, one must know the definition of a star text. A star text is the sum of everything we affiliate with celebrities, which includes their body of work, promotion, publicity, and audience participation (Jackson, 08/09/16). One must note that “celebrity doesn 't happen because someone has extraordinary qualities – it is discursively constructed by the way in which the person is publicised and meanings about them circulate” (O 'Shaughnessy and Stadler 424). Destiny Hope Cyrus, “an American singer and actress, became a sensation in the television series
The Tragedy of the Salmon The United States Pacific Northwest has historically been a significant player in the global fishing industry. However, over the last half-century, the fish population in the area has been declining at an alarming rate. Popular species of fish such as cod and salmon have been particularly susceptible to these decreases. What once was a region flourishing with abundant fish populations, is now in danger of being exploited to the point of extinction of certain species. The majority of these population drops is attributed to increased industrialization and overfishing in the region.
Salmon Rushdie In a world that is ready to criticize the slightest fault, or impropriety of a person's character, or way of thinking, authors, such as Salmon Rushdie, are continually under fire. In his writings, Rushdie takes the aspects of typical every day life and satirizes them in a way that enables his readers to realize how nonsensical they may be. Through centuries of diverse writing and literary changes, one thing remains the same: writers, no matter who they are, or what their standing in society is, will be criticized. Salmon Rushdie, although a modern writer, is faced with much criticism that earlier writers also faced.
efforts of gaining the admiration in society may appear as a seemingly possible task to attain, yet the
Salmon Farming If you recently ordered salmon off the menu of your favorite restaurant, or purchased it from your local grocery store, chances are it was farmed. According to “Salmon of the Americas, an organization of salmon-producing companies in Canada, Chile and the United States, 70 percent of the salmon produced in British Columbia and Washington comes from salmon farms. If it weren’t for these farms, we would not have the luxury and abundance of this delicious and healthy food available to us year round. Salmon farming represents one very important way to feed the world and people want to eat more salmon and seafood- more than can be caught.
British Columbia is the fourth largest aquaculture producer in the world. The province and everywhere else that loves seafood relies on the production of aquaculture. However, many do not know what they get when the glory of farming fish comes with. Salmon is one the most common fish and British Columbia wanted to make sure that who ever wanted it could get tons of it. While global warming has been driving wild salmon stocks up north, British Columbia came up with their own solution, Aquaculture. It was the perfect thing due to the fact, British Columbia has 20,000km of coastlines and 25,000 lakes and many rives and streams to raise fish. This became an advantage to fish farmers and aquaculture heads because the plentiful water allowed them to raise wish in any body of water. The economic benefits came pouring in as fish farmer could grow many fish all year round and have control of it. The salmon in these farms are raised in pens, just like you would see animals on a farm on land. B.C’s fairly clean waters, sparse population and accessibility to roads makes it well suitable for the fish to be raised from hatchlings to harvest. The net pens that held the salmon year round were limited to small spaces, developing some major issues in the ocean’s health and human health. Many have blamed farmed salmon for the sea lice. Sea lice have been depleting lives of many wild salmon as farmed salmon are allowed to escape from their nets into the ocean. Allowing the possible spread of sea lice. Sea lice are crustacean parasites that attach onto both farmed and wild salmon. These parasites do not kill the fish, however they drain the resources the fish need to survive and decrease their ability of swimming. The sea lice also create open abrasio...
What if the food you were eating right now was not what you thought it was? Instead of being grown like that rest of your food, taking a certain length of time or only growing during certain seasons, it was genetically modified to grow faster and with no consideration to season at all. This concept as farfetched as it may sound is not so farfetched after all with the production of genetically modified GM salmon trying to make its way into our fishers markets and grocery stores today. This process has been going on for almost 20 years, being done to crops and animals alike, however, GM salmon will be the first commercial GM food animal to hit the American market. However, with first come questions such as “what is the difference between salmon on the market currently and the genetically altered ones and is it harmful or harmless?”

The celebrity gossip industry has affected our assumptions about entertainment. Usually, we assume that entertainment is just for fun, entertainment is only a reflection of our culture, and entertainment is a personal choice. Nowadays, entertainment is not just for fun. Celebrities entertain us in many ways, but sometimes we do not enjoy what they do yet we still watch them. For instance, many teen idols have had meltdowns. Although it is not fun to...
Society always wants to keep an eye on their favorite celebrities’ life. It is fundamental. Every little detail the public wants to follow like what and where they are eating, whom they will marry, or what they are doing all day –such a vicious cycle.
