Oh, great. Well, that is off the menu.
There was an episode of Dirty Jobs that had Mike Rowe working at a fish hatchery. They raised both tilapia and striped bass, I believe it was. The bass were raised on regular food, while the tilapia were brought in to clean up the waste, both uneaten food and bass waste. The tilapia were chosen because they would both clean the tanks for them, and could be sold for food when they were large enough.
We’ve had some very clean tilapia, usually the best tasting was from Brazil. We absolutely refuse all the fish from China, especially the farm raised. It’s ridiculous how much fish in out local stores is Chinese. There’s even a company based in Gloucester; turns out they’re just packaging Chinese fish.
