> Beyond the notion that fish farms are a sustainable source of fish meat, the fact is that fish farming needs a fodder supply to feed the fish. This is not the only model. There are fish, specially freshwater, you can feed on algae and micro crustaceans, which in turn consume organic waste from traditional farming. That's where research is going into, and where fish farming is more promising, not the sea net model. Tilapia is produced in large scale this way quite successfully, and is a desirable meat that sells for a good price here in Brazil.
