Hatcheries in Canada produce about 750 million salmon and trout each year. This helps with fish populations and for people who enjoy fishing.Salmon farming begins in B.C. with small experiments. Farms for chinook, coho, and sockeye salmon are set up around Sechelt on the Sunshine Coast.Large-scale fish farming starts in Canada. Farms begin raising Atlantic salmon, which becomes the main type of salmon in B.C. Between 1986 and 1988, the value of the fish farming industry grows a lot, from $35 million to $433 million.Fish farms get bigger, and smaller companies are bought by larger ones. In 1997, a report says that fish farming in B.C. doesn’t harm the environment much at the current level. But by 1999, the number of fish escaping from farms leads to the creation of new rules for salmon farming.Fish farming grows four times larger in 20 years. It makes up 20% of Canada’s fish production and one-third of its value. In 2009, the Cohen Commission investigates why sockeye salmon in the Fraser River have been declining for 18 years. They suggest stopping fish farming in the Discovery Islands and changing how the government promotes and regulates fish farming.A virus called piscine reovirus (PRV) is found in farmed chinook salmon in B.C. The virus may cause a disease that weakens the fish, which is more dangerous for wild fish because they need to escape predators.A judge, Justice Cohen, says salmon farms in the Discovery Islands could harm wild salmon by spreading diseases. He gives a deadline of 2020 for the government to prove fish farms are safe or close them.Another judge, Justice Rennie, finds that fish farming companies were given too much control without proper oversight by the government. The rules were not followed well enough to protect wild fish.
