Re: [TheUWfarm] Aquaponics

I suppose tilapia could be a safe fish to eat if it is fed its natural diet. There was a study released last year that exposed how unhealthful a food farm-raised tilapia is when it is fed a corn-based feed. This creates an unhealthful balance between omega oils 3 and 6--the same problem with corn-fed beef. I know that Will Allen uses watercress to filter the water of its fish wastes (another problem of farm-raised fish), thus closing the loop. The watercress is also a good food value with lots of antioxidants.
