Also the non plant parts of it could be fairly efficient too. e.g see black soldier fly farming for fish feed. Not that that is a 100% answer for all feed for seafood farming, but interesting options abound.

Personally though, Octopi are too smart for me to eat. I'll always pass on it now.

Whatever happened to the Roach farming as a viable option for quality protein farming? I could see a flow like algae/hemp -> roach -> fish -> human

Soldier fly leaks from farms are more palatable than Roach leaks?
