How Does Salmon Affect The Environment?

The film Salmon confidential had initially been released on October 2nd, 2013; Since then, the status of British Columbia fish farming may just have a promising future. For too long has the fish farming industry in British Columbia gotten away with destroying the population of wild salmon. Despite this, recently the fish farming industry has been running into problems that threaten the survival of their industry in British Columbia. Currently, there are 130 floating fish farms in British Columbia, all of these fish farms have been infected with contagious diseases that are spreading to other wild salmon that travel in these areas. The companies in change of the fish farming have been trying to hide the fact that their farms have caused a major

Along with the sheer capability to sustain fish populations and feed the increasing demands of humans, the practice of aquaculture itself is a resource efficient way of producing protein. By nature, fish are able to convert more of their food into body mass than when looking at land animals. For example, farmed raised salmon are one of the most intensively-fed cultured fish, but according to the NOAA, when comparing the ratio of pounds of feed to produce a pound of protein, farm raised salmon has a ratio of 1.2 pounds of feed to produce 1 pound of salmon, which is still lower than the 1.9 pounds of feed to produce 1 pound of chicken (whereas Pork is 5.9lbs : 1lb, and Beef measures in at 8.7lbs : 1lb) (NOAA,

From the San Francisco Bay to streams and rivers of Oregon, salmon populations have been steadily decreasing over the past two decades but more rapidly within recent years. In general, fish populations in the Pacific Northwest region have always fluctuated, but the overall trend continues on a downward slope to extinction. While natural phenomena such as flooding and predators of the food chain do affect salmon populations, human activity poses the greatest threat by far. The four main reasons of salmon plummeting are as followed: Harvest, Hatcheries, Hydropower, and Habitat. It’s clear that water ecosystems and management of human activity threaten salmon as a whole. Whether it’s a bay, river or stream- whatever body of water that contains salmon should be subject to ethics that guide our actions as a part of achieving a better overall environment.

Essential Question: In what ways do humans actions and interactions affect the health of Puget Sound?

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

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

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

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

Salmon has something called omega 3 fatty acids, this lowers the risk of getting a heart disease. These are some health benefits of salmon, omega 3 fatty acids, protein, high in vitamin b, potassium, full with selenium, will reduce risk of heart disease, could benefit weight control and help brain health. Salmon also has a really good amount of the antioxidant amino acid taurine. Salmon is a really good cause of vitamin B, vitamin D and selenium . It is a good cause of niacin, omega-3 fatty acids, protein and phosphorus. It is a good cause of choline too, pantothenic acid, biotin and potassium.

The increase of fish meal and fish oil prices has urged aquaculture companies to use alternative ingredients for feed production. However, nutritional imbalances caused by the replacement of marine ingredients can reduce growth rates, and may also alter the immune response or reared fish. In this study we aimed to evaluate the effects of an extensive replacement of dietary fish meal and oil by plant and animal ingredients on the immune response of Atlantic salmon. During a 14-week trial, Atlantic salmon were fed a fish meal-fish oil based diet (FM), a diet based on plant protein and oil (VEG), and a vegetable oil-based diet with animal by-product meal as major protein source (ABP). At the end of the trial, salmon were injected with either phosphate-buffered

“How to Farm a Better Fish” by Joel K. Bourne, Jr. was published in National Geographic’s June, 2014 edition magazine. This particular article characterizes the differences between the various types of aquaculture, as well as what species to feed and the ingredients that make up the food given. The reporter who composed this editorial informed the reader of the advantages and downfalls of an indoor fish tank vs. an outdoor fish pen. The reporter pointed out the numerous ways an aquacultural company may feed their harvest of fish. He even explained that some fish farms have a whole ecosystem of aquatic animals and plants that they feed instead, to supply the whole food chain with enough nutrients. This is a rather important article because

How do our actions and natural changes affect the world around us? What events impact a community? There are four major events that have the most effect. These include: global climate change, human activity, the introduction of new species, and geological events.

Salmon is acclaimed as a superfood because of its omega-3 fatty acid content, which is known for its numerous health benefits. One of these is its ability in keeping the heart healthy by decreasing the risk of many cardiovascular problems such as stroke, high blood pressure and heart attack. Regular consumption of foods high in omega-3 are also found to be beneficial in improving mood and cognitive function. It decreases the risk of cognitive decline in older people as well as decreasing the risk of other brain-related problems.

Seafood is not only consumed by humans but also by others creatures living in water and on land such as bigger fishes, bears, and whales. Seafood contains full of many of the things our bodies need to operate as nature planned. Seafood contains protein, vitamins, minerals, fats, omega-3 fatty acid. Although seafood can be cooked in different ways but cooking treatment can affect the amount of nutrients in seafood. Ocean is the primary source of food for more than 3.5 billion people. (8)

“Give a man a fish and you feed him for day, teach a man how to fish and you feed him for a lifetime,” said the Spanish scholar Maimonides nearly a millennium ago. Fishing is a critical source of nutrition for the ever expanding demands of the modern world. The method of farming, feeding and harvesting of fish, shellfish and aquatic plants have been practiced by humans for centuries. It is not until 2012 when aquaculture accounted for nearly 42 percent of the total global seafood production. (FAO, 2014) Being the fastest growing food production industry in the world, aquaculture mostly thrives in Asian countries such as China, India, and Vietnam with global production value at 137.7 billion USD in 2012. (FAO, 2014) However, the negative impacts of aquaculture remains prevalent. China, being the largest producer of aquacultural products, has faced eutrophication and fish waste pollution as a result. (Liu, 2005) Counteractively, the Chinese government has set standards for regulating antibiotics and chemicals used as well as filtering pollution and waste. (NBSO, 2010) Aquaculture is also able to alleviate the lack of activity commonly found in developing nations. Given time, links of food security, rural development, improved nutrition and established services can all be drawn to aquaculture. (FAO, 2006) In the past, rich resources of fish and marine
