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 …show more content…
AquAdvantage salmon contain two extra genes from other fish that make them grow to full size twice as fast as natural salmon. The AquAdvantage salmon are all female and possess three chromosomes instead of the usual two. AquaBounty Technologies, claim the risk of interbreeding with wild salmon is love because their fish are all sterile and grown in secure containers on land-based fish farms (Frankenfish, 2012).
Genetically modified salmon is currently categorized as a new animal drug. One of the major concerns over genetically modified salmon, and genetically modified food in general, is whether it is safe to eat. So far, the answer remains a unknown, though the latest studies suggest that genetically modified foods are safe to eat in general. However, the concerns over genetically modified salmon aren’t only based on the health effects. Concerns over the environmental effects dominate many conversations about genetically modified organisms (Genetically Modified Salmon , 2012). In the past it was found that in the fishing industry, the success of farm-raised Atlantic salmon made some people who worked in the commercial wild salmon fishing industry especially sensitive to potential impacts of GE salmon. Fishermen had concerns related to further increases in salmon aquaculture production and environmental harm to wild stocks. The salmon

An electronic model showed that 70 escaped genetically modified fish interbreeding with the native population of 59,000 wild fish would end with the native fish extinct within 41 generations. In an effort to prevent effort to prevent effects from escaped fish, AquaBounty officials said they would raise only female fish that are 99% sterile. Any fish that does escape would not be able to reproduce (Genetically Modified Salmon ,
In the California Central Valley, fall‐run juvenile Chinook salmon rear typically from January to June. However, in some years, the rearing period may be reduced due to high water temperatures in April. Growth and survival rates of juvenile Chinook salmon are affected by water temperature and cover (e.g., substrate pore spaces, gravel interstices, boulders, snags, over‐hanging vegetation, root wads, under‐cut banks, and macrophytes). Cover is important for protection from predation, flow displacement, water temperature stress, and the fish caloric intake optimization. Human-induced sources of stress to the riverine ecosystems include: “(1) overfishing (i.e., extracting larger quantities of fish than the system can sustain naturally); (2) nutrient
The government had begun to ban any studies that were being done on salmon. The government also closed down labs that were performing experiments on salmon. A lot of profit is made by the government, from the sales of farm fish that is sold locally and exported. After taking all the research and all the results for salmon research and experiments, it was said that the results were negative. In reality, the salmon were highly infected with Infectious Salmon Anemia. These results came from labs that were not funded by the government or farm fish industry. If it was announced that the results were positive, Fish farms would be closed down, causing less earning by the government.
The U.S. Food and Drug Administration approved a commercial selling and consuming of the first GM animal, a salmon fish. However, instead of taking this news favorably, the U.S retailers refuse to sell it in their stores. One of these retailers is Costco, the second-largest warehouse retailer in the world.
Even though some of the problems were inherent were market failures, ineffective or counterproductive government interventions. They wanted the current regulatory regime change to a policy that was based on exclusive ownership of the salmon fishing rights for specific rivers. “There were four policy that analysis examined: (1) the status quo policy, (2) harvesting rights, and (4) individual transferable quotas. All four are evaluated
Founded in 2001, Yorktown Technologies, Inc. is a company that specializes in the ornamental fish industry. The globalization of the ornamental fish industry happened over a half a century ago. Hundreds of freshwater and saltwater fish can be purchased as pets in virtually any industrialized nation in the world (Broy, 2011). Yorktown Technologies commercializes a genetically modified fish called GloFish, which appear to glow in the dark (Mueller, 2010). GloFish are zebrafish that have been genetically modified with fluorescent colors. They are the first genetically modified animals to become publicly available as pets
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.
In the North Pacific there are five species of salmon. Each kind of salmon is known by different names like, Chinook (king), sockeye (red), coho (silver), chum (dog), and pink (humpback). These are all valuable, but the Chinook or King Salmon were the prize of the Columbia River system. In the late 1800s about 2,500,000 cans of salmon nearly filled a cannery store and storage rooms in Astoria, Oregon. Fresh, salted, dried, and smoked were the only options for preserving and eating salmon before the spread of canning technology in the mid 1800s.
Salmon hatcheries have been operated for a variety of purposes throughout their its history in this region, from harvest augmentation, to mitigation of habitat destruction, to conservation and preservation of native populations. Despite this long history, we are only just beginning to understand how hatchery-raised fish interact with and effect wild populations of salmon. Research shows that captive-bread salmon impact wild salmon in a variety of ways, from competing with them directly for resources, to reducing the fitness of wild populations through interbreeding between wild fish and less-fit hatchery fish. These findings have serious implications for the hatchery industry, and as the focus of hatchery operation switches from augmentation
Salmon have a truly incredible life cycle. Like all fish, salmon spawn from female eggs and then go on to develop into “alevin,” which is a term for newly hatched fish. First off, they derive nourishment from the yolk sac from where the salmon are born. Once the sac has been absorbed, the “fry,” or baby fish, then emerges from the river gravel and starts the search for food. Fry instinctively deal with the river currents and learn to swim together as a school right away. Anywhere from a couple days to two years old, fry will continue to live in fresh water until they start the next, “smolting,” phase. Smolting is a
They created genetically modified zebrafish by injecting the zygotes with the GFE3 construct that was further modified to be expressed only in the spine.
Salmon also known as the “Kings” of the streams can be wild caught or farmed. Adolescent wild salmon eat insects, invertebrates, and plankton. Adult wild salmon eat other fish, squid, eels, and shrimp. The salmon which is farmed usually eat a dry pellets which has canthaxanthin or astaxanthin added to them to create that appealing 'salmon ' color. Also, some of the farmed salmon are even tainted with Agent Orange, a chemical used in the Vietnam War to poison the opposing side. Most farmed salmon are kept in small ponds where they are able to grow and get bigger. The ponds are usually overcrowded and full of chemicals. The pond water is most likely at a cold temperature, which the natural temperature that the salmon adapted to. The pond water is also full of salmon waste and is barely ever cleaned. This can lead to the salmon to become a health risk to the
Consumer groups such as Consumers Union, Food and Water Watch, and Center for Food Safety have created a petition in which they are claiming that genetically modifying the salmon changes the nutritional value and alters the composition of the fish, therefore making the fish a food additive (Barret, 2012). If GM salmon are considered to be a food addictive, then the Food and Drug Administration (FDA) will have to place the GM salmon under extensive testing to make sure that it is safe for consumption (Barret, 2012). Other concerns are based on the consequences of these GM fish escaping into the wild and reproducing with other non GM fish (Barret, 2010).
The parade of genetically engineered marvels, during the past recent years, has been shocking: “Flavr-Savr” tomatoes that stay fresher longer; “giant salmon” that grow 37 times faster than the normal fish; “transgenic” pigs that are injected with human genes which causes them to produce milk with human protein that prevents blood clotting; and “supermice” injected with rat growth genes which makes them grow twice their normal size, are just a few.
The new genes added into the organism may grant them a competitive advantage that they would not normally possess. The possible repercussions if the organisms were to escape the labs, they can upset the natural balance of nature and lead to either the endangerment or extinction of a
Generally raised in hatchery environments, GMO salmon, also known as AquAdvantage salmon, will pose a risk to other fish and their respective food chains when combined. AquAdvantage salmon are genetically modified to grow more rapidly than wild salmon, which changes their life span. Natural
