came to the conclusion that there is no correlation between farmed salmon louse numbers and returns of pink salmon to the Broughton Archipelago. [53][54] Other welfare concerns of GM fish include increased stress under oxygen-deprived conditions caused by increased need for oxygen. [35], AquaBounty indicates their GM salmon can not interbreed with wild fish because they are triploid which makes them sterile. [14] Farmed salmon in open net cages can escape into wild habitats, for example, during storms. Late 1960s: First salmon farms established in Norway and Scotland. [57] GM coho salmon show greater risk-taking behaviour and better use of limited food than wild-type fish. (e.g. They also eat fish eggs and adult forms of terrestrial insects (typically ants, beetles, grasshoppers, and crickets) that fall into the water. In rivers and streams populated with other salmonid species, rainbow trout eat varied fish eggs, including those of salmon, brown and cutthroat trout, mountain whitefish, and the eggs of other rainbow trout. That's it. [15], Contaminants are commonly found in the flesh of farmed and wild salmon. 2019: The first salmon fish farm in the Middle East is established in the United Arab Emirates. The US in their dietary guidelines for 2010 recommends eating 8 ounces per week of a variety of seafood and 12 ounces for lactating mothers, with no upper limits set and no restrictions on eating farmed or wild salmon. It has been suggested the fish might be used as indicators of aquatic pollutants or other factors which influence development. [17] This market shift at constant production appears an economic decision implying that the development of salmon aquaculture had no impact on forage fish harvest rates.

[106] Cultured steelhead are fed a diet formulated to closely resemble their natural diet that includes fish meal, fish oil, vitamins and minerals, and the carotenoid asthaxanthin for pigmentation. Published PCT Application WO2000049150 "Chimeric Gene Constructs for Generation of Fluorescent Transgenic Ornamental Fish." 6. Rainbows also consume decomposing flesh from carcasses of other fish. The rest are farmed, predominantly from aquaculture in Chile, Canada, Norway, Russia, the United Kingdom, and Tasmania. Such debate and positions were central to a 'halt' in the re-certification of Alaska salmon fisheries by the Marine Stewardship Council (MSC) in 2012. [93] In the United States, a major investor in the effort was Atlantic Sapphire, which plans to bring salmon raised in Florida to market in 2021. Diploid AquAdvantage salmon (less than 1% of AquAdvantage salmon) did have statistically higher levels of allergen content, but experts concluded that there would be no impact on non-allergic consumers, and no change in allergenicity for allergic consumers. [2] The most commonly commercially farmed salmonid is the Atlantic salmon. [98], Many Atlantic salmon escape from cages at sea. Wednesday, Dec. 19, 2012. [failed verification], Coho salmon mature after only one year in the sea, so two separate broodstocks (spawners) are needed, alternating each year. [22] Unfortunately, this substitution can result in lower levels of the highly valued omega-3 content in the farmed product. [59], In 2006, eight Norwegian salmon producers were caught in unauthorized and unlabeled use of nitrite in smoked and cured salmon. [15], Chinook salmon are the state fish of Oregon, and are known as "king salmon" because of their large size and flavourful flesh. Another comment in the scientific literature by Canadian Government Fisheries scientists Brian Riddell and Richard Beamish et al. An older method of harvesting is to use a sweep net, which operates a bit like a purse seine net.
