I am also new, I am worry about raising fish

[Maria Saleme]

I live in a small caribbean island, and there are limitations on species that are not local , can i just focus in the vegetable production and not in the raise of fishes? In that escenario, does it really matter the type of fish, can I use just local fishes or do they need specific characteristics in order to get the benefits of aquaponics (less watter, less energy, higher growth rates)? Help me please!
