> The species matters a lot. Tilapia, catfish, and carps use very little wild fish in their feed

The big problem with herbivores is that nobody really likes their muddy taste. This market only works if you can raise this fishes for free with organic discards. Sea Aquaculture is a totally different planet.

I'm aware of the inclusion of vegetable proteins on the diet since decades, but is a tricky issue. Too much of them and the fishes don't grow well, and too low and the costs of feeding your fishes raise over the value of your fishes in the market. And you still need to import your food. This is a big point. Unexpected 10% more of tariffs just because the president farted that night, means the death of your company.
