Domestic Salmon: Case Study

Juvenile Pacific Salmon and other migratory marine animals are travel many long distance under water to use resources in different oceanic regions. The main question is how these marine animals travel many long distance and able to locate Specific Ocean feeding areas without previous experience. Researchers experimentally demonstrate that the juvenile chinook salmon respond to magnetic field which lead them toward their marine feeding grounds. The “magnetic map” of Juvenile salmon to be inherited. These results, Similar with findings in the sea turtles indicate that the magnetic maps are genetically wide spread and show their navigational abilities evident in many long distance under water

The average period of time that sockeye salmon live in the wild is 4 to 5 years. The oldest salmon that was caught was 8 years of age. Usually sockeye salmon die after mating (“Longevity, aging and life history of Oncorhynchus nerka”, 2009; Groot, 1966)One thing about sockeye salmon that is special and unique about them is that they swim in runs when migrating to freshwater streams to spawn. They additionally establish gregarious hierarchies, conventionally at times of reproduction. The most astronomically immense male is most ascendant (Crutchfield and Pontecorvo, 1969; Quinn, 2005). The predators of sockeye salmon are considered to be bears, lake trout, squawfish, mountain whitefish, and birds such as mew gull. Humans additionally consume a considerable about sockeye salmon.

There are many risks associated with eating farm-raised salmon versus wild- caught salmon. One risk that farm raised salmon faces is contaminants that can lead to cancer. Farm raised salmon are placed in artificially made bodies of water such as ponds, lakes, and salt water and within these bodies of water, contaminants such as PCBs can be present. Cancer causing chemicals can be present in both the water, farm-raised salmon swims in, and the food they eat. Another risk with farm-raised salmon is the use of antibiotics in order to keep the fish healthy. This unknown amount of antibiotics used on the fish can lead to a resistance to the antibiotic used to kill the bacteria’s in both human and the salmon. The humans that are consuming the fish that possess these antibiotics are unintentionally

Commercial fishing boats are pushing to catch as many Atlantic salmon as they can after a net pen broke near Washington's Cypress Island. Fishermen reported thousands of the non-native fish jumping in the water or washing ashore. The pen, in the state's northwestern San Juan Islands, contained about 305,000 Atlantic salmon. Environmentalists are concerned that the escaped Atlantic salmon could potentially mate and crossbreed with the Pacific salmon or compete with them for food but they are not completely sure what the ramifications will be. Now, owner Cooke Aquaculture and the Washington department of fish and wildlife are trying to determine how many escaped. The director of the wild fish conservancy northwest, Kurt Beardslee , called the

Navigating the World’s oceans is a difficult task, finding a small place where you were born two years earlier without any navigational tools at all is impossible for most. Pink Salmon are an incredible species capable of this and so much more, but now they are faced with their greatest challenge to date. Pink salmon must somehow survive the changing chemistry due to climate change that is altering their environment, and poses the greatest risk the species will likely ever face.

There are so many options for an environmentally conscious consumer these days looking to buy groceries, with the multitude of different eco-labels popping up each time you visit the grocery store, it’s becoming more difficult to know which products are the right ones to buy. “Salmon Safe” products line our shelves from wine bottles to produce and are status’ given to places like the Nike campus and golf courses. Is this just another label to get us environmental minded consumers to buy their products or is Salmon Safe actually effectively helping to restore the Pacific Northwest (PNW) salmonid species? Salmon safe certification works across the entire region of the PNW but

For our groups visual communication strategy we chose to create a children's picture book. Our book will target elementary school children in the North Vancouver Area, specifically between the ages six to ten years of age. Our group would start by targeting one or two elementary schools in North Vancouver as they are located near the Capilano Salmon Hatchery. The location increases the relevance and connectivity of our specific topic to the kids and their parents. Our book will focus on communicating the negative impacts that both climate change and humans have on our local salmon population, through the primary use of illustrations and short “kid-friendly” dialogue. Our report will delve deeper into the science and details of the causes, impacts, vulnerabilities and possible solutions that both local people, and larger forces (ex.government, or NGO’S) can take in order to protect Vancouvers salmon stock.

Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) both belong to the genus Salmo.

For this project, we are researched the salmon trade and how it has evolved over the years. The salmon commodity chain has three main consumers – the United States, Japan, and China. The development of aquaculture has changed our consumption of salmon drastically over the past decades, with Norway leading the aquaculture industry, and Chile fast catching up. Because of differing standards of farming, the quality of cultivated salmon varies; some farms may use chemicals, while others focus on a sustainable farming process focused on longevity of humans, salmon, and the earth. Atlantic salmon used to overflow waters ranging from Quebec to Newfoundland, all the way southwest to Long Island Sound. Come the beginning of the 19th

In The salmon fished in British Columbia generally migrate from the ocean and into nearby watersheds to spawn. While in the ocean, salmon depend on a diet of small fish, such as krill and herring. However with the risk of biodiversity depletion, many of these species may disappear, affecting fish populations globally and British Columbia’s salmon population. If our local salmon populations were to decrease, the long term effects would greatly disturb the killer whale and bear populations that depend on the fish, the indigenous people, the fishing business, and overall

1. Griffiths and Armstrong used a variety of different sources when explaining the significance of the study they wanted to attempt. They based their study off of the Hamilton model of social behaviour and its evolution, this models states that an individual is able to aid in their own fitness through the general fitness of the population, this occurs when an individual is less aggressive and attempts to support it’s relatives. As well it was found that individuals that are related to one another tend to be closely associated. When looking at the Atlantic salmon it was discovered that they use a chemical to recognize and aggregate with their kin. Many laboratory tests were conducted similar to the one Griffiths and Armstrong

INTRO: A keystone species are one that is essential to the function of the ecosystem as a whole. They are a biological foundation that supports the entire internetworkings of life. They are the ones that many other animals cannot do without and without them the ecosystem will unravel. Every summer millions of Atlantic salmon return to the coast to fill hundreds of streams and rivers, just as they have for hundreds of years feeding many different species including the local people, those throughout the nation and feeding many local economies. Yet quietly and without a proper explanation the number of salmon is beginning to dwindle and is on the edge of distinctions. Few if any are returning to the rivers and are dying mysteriously before they have a chance to lay their eggs. One thing we do know is that salmon do not have an appropriate habitat for reproducing and the upbringing of the young and it is essential to have one for the continued existence of the species. Without them we will lose a key

Salmon artificial selection would be beneficial because we will get bigger Salmon.Their explanation is logical because if we get bigger Salmon we can feed more people,but at the same time if something goes wrong then we can make too big salmon and we wouldn’t know how to reverse it and who knows what will happen.So i am in the middle for this Explanation.

AquAdvantage salmon is the field name for a genetically modified Atlantic salmon developed by AquaBounty Technologies. A growth hormone-regulating gene is taken from the Pacific Chinook salmon and a promoter is taken from the Ocean Pout salmon and added to the Atlantic salmons 40,000 genes. The whole purpose of the modification of the salmon is to increase the growth rate of the salmon, without affecting its ideal qualities or size. (Genetically Modified Salmon: What is it?, 2012). Essentially, the modification works by ensuring that the salmon growth cycle is continuous rather than seasonal. As a result, the fish grows to the preferred size within a time period of 1.5 years instead of 3 years; this is exactly half the time it takes for a regular

Pacific salmon are a major driver in Washington’s economy. Although the wild salmon population has increased slightly since the legislation passed by Washington in 2011 regarding the restoration of Pacific salmon, I believe a major issue still lies ahead regarding salmon aquaculture. Salmon aquaculture, or salmon farming, refers to the manufacturing of salmon from egg by using open net systems in oceans. With the current National Oceanic and Atmospheric Administration (NOAA) declaring the United States marine aquaculture industry to be valued at over $1.2 billion, the industry of farmed seafood will never be diminished fully. As this national empire increases, it is crucial that government set regulations for the impact that the aquaculture
