Good article about a working alternative to in water fish farms. This is a rated “green” tilapia farm near Sumas. No waste water is sent to the rivers. The way forward? It certainly takes away the arguement that this is an “in-water” dependent business. Have to see if we can get local restaurants to carry the fish. I’d pay a bit more to support this, wouldn’t you?
Sumas Lake Aquafarm’s fish are imported as fry and raised in a closed-containment system in a former dairy barn. Water is circulated among 24 large metal tanks, each containing about 5,000 fish, and a sophisticated filtration system using RAS (recirculating aquaculture system) technology. The farm is completely bio-secure, and no waste water is released into the environment.

I looked in on some small scale land-based fish farms in California. They were raising either tilapia or catfish in ponds which were also used to grow rice. Tilapia and catfish eat at the bottom of the food chain, so they’re more efficient at converting fish food to fillets than salmon are.
