(British Columbia, Canada, Farmed in Tank Systems)
White sturgeon and white sturgeon caviar farmed in Canada in closed, recirculating systems is a "Best Choice."

The white sturgeon is native to the Eastern Pacific from Alaska to Monterey, California. They can grow to 18 feet in length and live up to 100 years. Females come to reproductive age at about 18 years. These slow-growing, long-lived characteristics have made white sturgeon particularly vulnerable to overfishing. Declining populations, with increasing demand for sturgeon meat and caviar drove the advancements in sturgeon aquaculture technology.
White sturgeon 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.
By using feed ingredients that are not solely reliant on wild fish, there is also less impact to the environment.
