(Alberta, Canada, Farmed in Tank Systems)
Nile tilapia farmed in Canada in closed, 100% recirculating systems is a "Best Choice."
Tilapia is a fast-growing tropical species, native to Africa, but produced in more than 100 nations, surpassing any other farmed fish. It is the fourth most consumed seafood in the United States after shrimp, tuna and salmon.
Tilapia in Canada is raised in land-based farms that are "closed" from the surrounding environment, and therefore limit the impact the operation can have on local ecosystems. Risk of disease spreading, or escape of fish from the farm is minimized. Water and effluent can be treated, and with minimum use of chemicals, and water that is recirculated, the outputs from the farm can be minimized and even re-used as fertilizer.
By using feed ingredients that are not solely reliant on wild fish, there is also less impact to the environment.
