Aquaculture is the farming of aquatic organisms such as fish, crustaceans, molluscs, and aquatic plants. With global seafood production being approximately 51.7 million tons in 2006 and having an annual growth rate of 6.9% from 1970 to 2006, aquaculture is one of the fastest growing sectors in the food industry. Salmon aquaculture in British Columbia began in the early 1970s, from humble beginnings with mostly small operators in coastal areas around Vancouver Island. Today, the industry has grown to be a significant part of the marine fisheries in the province and an important contributor to the economy, creating close to 6000 jobs, resulting in $224 million in wages for British Columbians . There are approximately 740 aquaculture operations in British Columbia that are producing salmon, other finfish and shellfish year round.
