Responsibly farmed usually refers to ethical treatment and has nothing to do with CO2. That being said, I am totally in agreement that eating fish has pretty substantial problems. The thing is that fish more wholistically face problems resulting from global warming including coral bleaching and ocean acidification to name a few. Overfishing and harvesting of marine life in nonsustainable ways is just that, but if you are selective about the species and the source it makes a big difference.
