I think indoor/raceway farmed fish is the future, once we work out sustainable food sources, eg insects.

I'm not sure how credible that is for marine species, but I'm sure it's possible for some, and we don't have to completely cut fish from our diets.

In the meantime, I agree, we should be banning the sale/import of some species of fish.

Black soldier flies harvest themselves. The omega 3 fatty acids in fish come from algae. Duckweed is one of the fastest growing plants out there and is protein packed.

The above is the combo I think would be the path to support such a raceway system. One of many crazy dreams I have is to start a trout farm based on that.

Why insects? Tilapia eat plants, and other fish eat tilapia.

Then that should work too. I think current practice is often to feed larger carnivorous fish with smaller wild-caught fish, which doesn't really solve the problem.

Wow a vegetarian fish, I never contemplated such a thing. What kind of plants do they eat anyways?

They eat basically anything. They are a very non picky fish. Algae is a favorite.
