Is there aquaculture in Canada?
Aquaculture is the farming of fish, shellfish and aquatic plants in fresh or salt water. In Canada, aquaculture was first used to enhance natural stocks. It is now a large-scale commercial industry across the country. It provides direct and indirect economic benefits to many local and regional economies.
What is the trend for aquaculture in Canada?
Revenue expectations for the Fishing and Seafood Aquaculture industry in Canada have been adjusted from growth of 1.6% to a decline of 8.4% in 2020 due to the forecast downturn in the value of exports.
What are the 4 common methods in aquaculture?

- Pond Systems. The oldest type of fish farming is the pond system, which originated thousands of years ago.
- Open Net Pens.
- Submersible Net Pens.
What are the four types of aquaculture systems?
There are four main aquaculture grow out systems/techniques (or combinations of these). These four aquaculture grow out techniques are pond, cage, flow through or RAS. Based upon the climate, availability of water, land and electricity the decision of aquaculture grow out systems are made.
What are the aquaculture equipment?

What is Blockchain in aquaculture?
Blockchain in aquaculture and fisheries has reduced transaction processing time, fostering a relationship of reliability and trust between the food producers, governments, retailers, certification bodies, and consumers.
How many aquaculture farms are there in Canada?
The volume of production increased from 11,000 tonnes to almost 69,000 tonnes from 1989 to 2009. There are in excess of 500 farms employing 4,000 people in support of the aquaculture sector in Atlantic Canada (Gardner Pinfold, 2010).
Where is aquaculture Practised in Canada?
Aquaculture occurs in all provinces and the Yukon Territory and we farm more than a dozen types of fish and shellfish commercially. While most of Canada’s aquaculture operations are found on the east and west coasts, freshwater trout operations are found in almost every province.
Which maritime province contributed the most to aquaculture production in 2019?
2.2 Provincial Aquaculture Production In 2019, Canada’s finfish production was led by British Columbia (B.C.), while shellfish production was greatest in Prince Edward Island (P.E.I.). Both provinces accounted for roughly 60% of overall production in their respective categories (see Tables 1 and 2).
What are aquaculture systems?
Recirculating aquaculture systems (RAS) operate by filtering water from the fish (or shellfish) tanks so it can be reused within the tank. This dramatically reduces the amount of water and space required to intensively produce seafood products.
What’s new in aquaculture technology in Canada?
Canadian companies and researchers have participated in major technological developments including some of the first commercial land-based recirculating aquaculture systems (RAS), floating closed-containment systems (CCS), offshore production systems, and a range of sensors, remote operated vehicles, software and other system advancements.
What is aquaaquaculture?
Aquaculture is among the fastest growing food sectors in the world, accounting for nearly fifty per cent of the world’s total fish production.. Canada is a global leader in responsible and sustainable best practices.
What is the future of salmon aquaculture in BC?
Each of the production technologies can advance environmental, social, and economic performance of salmon aquaculture in B.C.; Land RAS and hybrid production technologies are ready for commercial development in B.C., while floating containment and offshore production systems need up to 5 years and 10 years respectively to evaluate their potential;
How much of Canada’s aquaculture is Atlantic?
About 50% of Canada’s aquaculture production originates in Atlantic Canada and there is ample room to double or triple its output. Two thirds (65%) of the current volume consists of finfish such as salmon and trout, and one third (33%) consists of shellfish such as mussels and oysters (Statistics Canada, 2010).
