Looks like farmed fish is 50%. However, they feed farmed fish wild fish apparently. Takes 5 lbs. of wild fish to grow 1 lb. of farmed fish. Hmmm... doesn't so

However, they feed farmed fish wild fish apparently. Takes 5 lbs. of wild fish to grow 1 lb. of farmed fish.
Hmmm... doesn't sound sustainable.

- jakogut 5y agoI don't get why black soldier fly larvae isn't more common and popular as animal feed. BSF larvae have numerous advantages, including eating their weight in organic matter very quickly, and being a good mix of fat and protein for growing out farmed animals. The adult flies also have no mouth parts, and do not hang around people or spread diseases as a result.
- martinpw 5y agoYour link refers specifically to salmon for the 5:1 ratio. Overall the article says it takes 20 million tons of wild fish to feed 51.7 million tons of farmed fish. Which is still a significant amount.
