Fish farming good for fish in the ocean?
As a reaction on the news that we may have depleted the world-wide fish stocks in 40 years the NELHA based Kona Blue fish farming company said that they have the solution to the problem: fish farming. But they are farming a carnivorous fish which means that approximately 3-10 times as much fish is taken from the sea to feed the farmed fish. You have a loss in protein in that chain. Until you farm the feed as well I don’t think you can become sustainable in the light of collapsing fish stocks. That said, I think Kona Blue is doing better than most fish farms, but more work is clearly needed.
