Canada has one of the world's most valuable commercial fishing industries, worth more than $5 billion CAD a year and providing more than 120,000 jobs to Canadians. It is the economic mainstay of approximately 1,500 communities in rural and coastal Canada. In total the capture fishery accounts for 76 percent of total fish and seafood production in Canada. Together, lobster, crab and shrimp comprise 67 percent of the landed value of all fish and shellfish harvested in Canada. Canada's aquaculture sector continues to increase in importance. Key products are farmed salmon (Atlantic, coho and chinook), trout, steelhead, Arctic char, blue mussels, oysters and manila clams. New species like halibut and cod are on the way. Canada is the world's seventh-largest exporter of fish and seafood products, with exports to more than 130 countries. In 2008, Canada's fish and seafood exports were valued at $3.9 billion. Canada exports an estimated 80 per cent, by value, of its fish and seafood production. The United States is Canada's largest export market (representing roughly 62 per cent of seafood trade) followed by The European Union (15 per cent), Japan (8 per cent) and China (6 per cent). Canada's fish and seafood imports have stayed at around $2 billion, resulting in significant annual trade surpluses.
