How much of this was farmed seafood? I have a friend right now who is planning on opening fish farms because he feels it will have less of an environmental impact.

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 sound sustainable.

I 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.

Your 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.
