There are two ways to produce seafood: catch fish in the wild or farm your own. Seafood farming is often called “aquaculture”. Aquaculture is dominated by the farming of fish, but also includes other organisms, such as crustaceans and aquatic plants.
I’m skeptical about this.
My understanding is that the most profitable aquaculture species are carnivorous fish, meaning that aquaculture has long been a net consumer of fish - it takes more weight of wild caught prey to feed farmed fish than the weight of fish produced.
I don’t see any mention of that in the data or analysis.
From other sources, one third of aquaculture (in weight) is algae.
Is algae for fish food or is it something I didn’t know it was in?
The Nori you eat with sushi is farmed, but quite a lot of aquafulture goes to the production of Carrageenan. That is used in tons for things from milk and meat products, to sex lubes, and toothpaste.
