Aquaculture is the breeding and growing of fish in controlled spaces. Also known as fish farming. Found on both East and West coasts In Canada, farmed salmon outnumber wild salmon 10:1 (so most of the salmon you eat is probably farm raised- check the labels to find out!)

Highly regulated industry PROS CONS Aquaculture provides 4000 jobs in BC and supports some coastal and First Nations communities Many farms are taking steps to make the industry safer, such as collecting waste Highly regulated industry Most of the fish food contains no antibiotics or preservatives Divers regularly inspect nets and ocean floor video Farmed salmon contains more fat and toxic contaminants Waste products from fish, uneaten food, and dead fish sink to the ocean bottom and pollute natural habitat Lots of diseases amongst farm raised fish Sea lice spread to wild salmon Antibiotics used to prevent disease contaminate water Nets often tear, allowing farmed salmon to escape Video
