AquAdvantage
AquAdvantage salmon is a genetically engineered (GE) fish, a GE Atlantic salmon developed by AquaBounty Technologies in 1989. The typical growth hormone-regulating gene in the Atlantic salmon was replaced with the growth hormone-regulating gene from Pacific Chinook salmon, with a promoter sequence from ocean pout. This gene enables the GM salmon to grow year-round instead of only during spring and summer. These GE salmon are a commercially competitive alternative to wild-caught salmon and to fish farming of unmodified salmon. The purpose of the modifications is to increase the speed at which the fish grows without affecting its ultimate size or other qualities. Fish-farmed Atlantic salmon growth rates have already been improved over wild fish as a result of traditional selective breeding practices. However, GM fish are able to grow even faster and grow to market size in just 16 to 18 months rather than three years. Significance AquAdvantage salmon are the first genetically e ...

Genetically Modified Fish
Genetically modified fish (GM fish) are organisms from the taxonomic clade which includes the classes Agnatha (jawless fish), Chondrichthyes (cartilaginous fish) and Osteichthyes (bony fish) whose genetic material ( DNA) has been altered using genetic engineering techniques. In most cases, the aim is to introduce a new trait to the fish which does not occur naturally in the species, i.e. transgenesis. GM fish are used in scientific research and kept as pets. They are being developed as environmental pollutant sentinels and for use in aquaculture food production. In 2015, the AquAdvantage salmon was approved by the US Food and Drug Administration (FDA) for commercial production, sale and consumption,Staff (November 201FDA Has Determined That the AquAdvantage Salmon is as Safe to Eat as Non-GE SalmonFDA Consumer Health Information / U.S. Food and Drug Administration / November 2015 / Retrieved 20 November 2015 making it the first genetically modified animal to be approved for hum ...

Genetically Modified Animal
Genetically modified animals are animals that have been genetically modified for a variety of purposes including producing drugs, enhancing yields, increasing resistance to disease, etc. The vast majority of genetically modified animals are at the research stage while the number close to entering the market remains small. Production The process of genetically engineering mammals is a slow, tedious, and expensive process.Murray, Joo (20)Genetically modified animals Canada: Brainwaving As with other genetically modified organisms (GMOs), first genetic engineers must isolate the gene they wish to insert into the host organism. This can be taken from a cell containing the gene or artificially synthesised. If the chosen gene or the donor organism's genome has been well studied it may already be accessible from a genetic library. The gene is then combined with other genetic elements, including a promoter and terminator region and usually a selectable marker. A number of techniques ...

AquaBounty Technologies
AquaBounty Technologies is a biotechnology company based in Maynard, Massachusetts, United States. The company is notable for its research and development of genetically modified fish. It aims to create products that aim to increase the productivity of aquaculture. As of 2020, sale of salmon has been approved in Canada and the United States. History The underlying genetic technology that accelerates the growth and reduces the time to market for the AquAdvantage salmon was developed in 1989 at Memorial University in Newfoundland, Canada. In 2003, the first regulatory study of the fish was submitted in the U.S. to the Food and Drug Administration (FDA), who ruled that the fish were safe to eat and posed no threat to the environment when farmed in land-based aquaculture farms. In 2012, a submission was made to Health Canada to allow the sale of the genetically modified fish in Canada and the application was subsequently approved. AquAdvantage salmon received FDA approval in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquaculture
Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus). Aquaculture involves cultivating freshwater, brackish water and saltwater populations under controlled or semi-natural conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture, commonly known as marine farming, refers specifically to aquaculture practiced in seawater habitats and lagoons, opposed to in freshwater aquaculture. Pisciculture is a type of aquaculture that consists of fish farming to obtain fish products as food. Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environmental source of food and commercial product which help to improve healthier habitats and used to recon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environment. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia. Global demand is increasing for dietary fish protein, which has resulted in widespread overfishing in wild ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Salmon
The Atlantic salmon (''Salmo salar'') is a species of ray-finned fish in the family Salmonidae. It is the third largest of the Salmonidae, behind Siberian taimen and Pacific Chinook salmon, growing up to a meter in length. Atlantic salmon are found in the northern Atlantic Ocean and in rivers that flow into it. Most populations are anadromous, hatching in streams and rivers but moving out to sea as they grow where they mature, after which the adults seasonally move upstream again to spawn. When the mature fish re-enter rivers to spawn, they change in colour and appearance. Some populations of this fish only migrate to large lakes, and are "landlocked", spending their entire lives in freshwater. Such populations are found throughout the range of the species. Unlike Pacific species of salmon, ''S. salar'' is iteroparous, which means it can survive spawning and return to sea to repeat the process again in another year. Such individuals can grow to extremely large sizes, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antibiotic
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit viruses are termed antiviral drugs or antivirals rather than antibiotics. Sometimes, the term ''antibiotic''—literally "opposing life", from the Greek roots ἀντι ''anti'', "against" and βίος ''bios'', "life"—is broadly used to refer to any substance used against microbes, but in the usual medical usage, antibiotics (such as penicillin) are those produced naturally (by one microorganism fighting another), whereas non-antibiotic antibacterials (such as sulfonamides and antiseptics) ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maine
Maine () is a state in the New England and Northeastern regions of the United States. It borders New Hampshire to the west, the Gulf of Maine to the southeast, and the Canadian provinces of New Brunswick and Quebec to the northeast and northwest, respectively.

Salmo Salar GLERL 1
''Salmo'' is a genus of ray-finned fish from the family Salmonidae. The single ''Salmo'' species naturally found in the Atlantic North America is the Atlantic salmon, whereas the salmon and trout of the Pacific basin belong to another genus, ''Oncorhynchus''. The natural distribution of ''Salmo'' also extends to North Africa and to West Asia around the Black Sea basin. The generic name ''Salmo'' derives from the Latin ''salmō'' (salmon). The number of distinct species and subspecies in ''Salmo'' is a debated issue. Atlantic salmon and brown trout are widespread species, while most of the other taxa are narrowly distributed forms endemic to single watersheds. Species The species currently listed in this genus are: * ''Salmo abanticus'' Tortonese, 1954 (Lake Abant trout) * ''Salmo aestivalis'' Fortunatov, 1926 (Lake Sevan summer trout) * ''Salmo akairos'' Delling & Doadrio, 2005 (Lake Ifni trout) * ''Salmo aphelios'' Kottelat, 1997 (summer trout) * ''Salmo balcanicus'' ( S. ...

National Environmental Policy Act
The National Environmental Policy Act (NEPA) is a United States environmental law that promotes the enhancement of the environment and established the President's Council on Environmental Quality (CEQ). The law was enacted on January 1, 1970.United States. National Environmental Policy Act of 1969. , Approved January 1, 1970. ''et seq.'' To date, more than 100 nations around the world have enacted national environmental policies modeled after NEPA. Prior to NEPA, Federal agencies were mission oriented. An example of mission orientation was to select highway routes as the shortest route between two points. NEPA was necessary to require Federal agencies to evaluate the environmental effects of their actions. NEPA's most significant outcome was the requirement that all executive Federal agencies prepare environmental assessments (EAs) and environmental impact statements (EISs). These reports state the potential environmental effects of proposed Federal agency actions. Further, U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
