This 20kg figure sounds wildly inaccurate. Fish feed is in general 75% plantbased. It is also very efficient (in terms of conversion rate to growth). Could this 20kg figure be decades old?

- shaneofalltrad 3y agoThis seems to be a very generalized statement when there is a lot of variation to consider. There are 33,000 fish species, some being specialized feeders of algae, to 100% live fish, all designed for processing each food differently. Are you speaking on a specific fish that is commonly "farmed"? I could see Salmon needing this 20kg and not even contain the quality fats they get in the wild, resulting in a lower quality food on top of being more impactful to the environment.
- dv_dt 3y agoAlso 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.
- shaneofalltrad 3y agoWhatever happened to the Roach farming as a viable option for quality protein farming? I could see a flow like algae/hemp -> roach -> fish -> human
- dv_dt 3y agoSoldier fly leaks from farms are more palatable than Roach leaks?
