I recently saw a documentary about some farmed fish that gets fed shredded hunted seafood - everything the fishers haul from the sea, it gets poured into a gigantic shredder and fed to that farm fish. There was a representative of some green organization who almost cried when she saw that, as it is such a huge waste of bio diversity.

Just saying that farming fish does not necessarily solve problems. And if the hunted fish is not being sold, but turned into food for farmed fish, it might be difficult to tax.
