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

The commercial fishing industry is a major source of income in my home region of Southeast Alaska accounting for about 11% of the total income to the entire region. Most of this income goes to smaller towns that rely almost entirely on the commercial fishing industry to drive their economies, and without it, these communities slowly fade away. Approximately 91% of the commercial fisheries catch is made up of salmon. Therefore, about 10% of the entire income of Southeast Alaska is reliant upon salmon alone. If you have not guessed this already, salmon are

construction to the site, and this would be costly. Big surface stones or rock outcrops may also make an area unsuitable for anything except lined ponds or concrete raceways for the fish.

There is a current discussion on whether we should genetically modify the growth hormone gene that the Chinook salmon is naturally born with. AquAdvantage is currently working on getting their genetically engineered transgenic salmon FDA approved. Their scientists have been able to make the common Atlantic salmon be able to grow to over twice its natural size by inserting the growth hormone gene from the Chinook salmon into the Atlantic salmon, however, there are wider implications to take into consideration before making these transgenic salmon mainstream.

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 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

When fish like salmon are farmed, often the fish are still kept in the ocean; however, they live inside of nets so that they are still contained. There are many ethical arguments based around these net systems because these nets pose threats to wild salmon. Captive salmon can escape from the nets, which allows them to breed with wild salmon. This can disrupt the natural gene pool of wild salmon. Farmed salmon have been shown to outgrow wild salmon when introduced into the wild, and typically have higher mortality rates, which would be poor traits to be introduced into the wild gene pool, (Hindar, et al., 2006). Unfortunately, with the invasive farmed salmon being introduced to wild populations from escapees of net systems, the recovery of the original wild salmon is unlikely, even if decades went by without more intrusive farmed salmon being present, (Hindar, et al., 2006). Another problem is that the nets do not contain wastes from the captive salmon inside, wastes such as uneaten feed, and feces from the fish are dispersed into the open waters of the ocean. Wild salmon can contract infections and parasites from captive farmed salmon in nets. A study indicated that these parasites, such as sea lice, and infections lead to high mortality rates in wild salmon passing near

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.

Salmon, a light pink colored delicacy which is supposed to be healthy for you. But is it really that healthy and good for the environment?These intrepid creatures swim against the currents of fury or they are packed into a small contaminated pond full of chemicals. This fish is over consumed by the world’s population. The chemicals in which farm raised salmon are grown in can cause the salmon to get sick, which then leads to the human to get sick too.Also the salmon production process is an environmental issue causing many streams to get polluted. Is salmon the best choice for your dinner? Let 's find out.

The earth’s oceans are overfished. Nearly 80 percent of commercial fisheries are overexploited and some experts believe that global fisheries will completely collapse by 2048 (Barkin page 1). While these are just facts that tell the worst-case scenario, they should be alarms that spark change in the way we fish. This paper, however, will specifically target overfishing in the Grand Banks in Newfoundland, Canada, and analyze its impact on Earth, its Environment and Humanity. Over fishing is simply when fishermen catch more fish than are being reproduced. Eventually the stock of fish in the environment will be completely depleted. That is exactly what happened off the shores of Newfoundland in 1992. With Cod fishing at an all time high, the Canadian government discovered that the Cod population was almost exhausted. New technology and poor decision-making led to the complete destruction of the cod population in the Grand Banks and this is a mistake that we should never repeat.

This problem is amplified in the recent overfishing of Bluefin tuna which is bringing the fish to near extinction. The documentary provides us with two alternatives for sustaining the population. The first is to counter demand by educating people on the hazards of over fishing and providing them with other alternatives such as flounder and other less at risk fish. However, time and time again modernity has shown that people are not prone to moderation and while the movement has gained some traction it has unfortunately failed to have to curve demand. The second option is to grow fish in aquacultures or farms which seems like a good idea at the surface. Capturing and growing juvenile Bluefin Tuna creates a controlled environment that does not require fishing and makes it easier to manage the population of fish in captivity and in the wild. However, Tuna ranchers use approximately 15 pounds of raw fish to produce 1 pound of Tuna. That’s a steep price to pay and may actually cause more harm to the environment. Therefore, until another source of protein is developed ranching is also an ineffective method for helping the Bluefin Tuna

In 2000, the salmon produced more than 1.1 million tons or 61% of the total production of salmon in the world. This trend is particularly evident in Norway, where the combination of reduced availability of wild resources and sustained increases of crops has resulted in the production of farmed Atlantic salmon is 100 times higher than the wild catch. In Canada, the decline of natural stocks of Atlantic salmon and Pacific has led to severe restrictions on the catch of wild species. In Chile, growing sustainably salmonid species has increased, reaching in 2000 27% of world production exceeding (52%) the value of exports of fishmeal and other marine products.
