But I saw on french TV a few weeks ago a doc on big french fish farms that go full vertical: since the crap catches are also collapsing, they are breeding their own bait fish to feed the noble species that have a market (Salmon, Daurade, what's the english for that ?? probably Bar/Loup aslo, which you gotta translate from one coast of France to the other)
Guess in a few years, they'll probably grow their krill in clone vats to feed the feed... Pierre
