I'm (very) familiar with salmon aquaculture, but know very little about other species.
As far as salmon go, there has been a huge push to reduce wild catch content in feed, replacing it things like soya. I don't have the numbers off the top of my head, but I recall being impressed - if you're interested, you can search for the latest MOWI annual report (think they call it a "sustainability report"), and Norwegian ministries publish a wealth of information.
- pvaldes 6y agoThe problem is that carnivore fishes are tasty, and vegetarian fishes... not so much. You can't just replace all their food by plant stuff and expect a good growth. 5-10% of soy, maybe, I' don't remember the exact value, but > 50%... No way. Fishes get ill and growth is stunted. It promotes cannibalism also. Premium fish food for aquaculture is expensive.
