Yup, that's the type of facility I used to work in.
It was great in theory but in practice it failed miserably and they had lots of didease problems with both the plants (basil) and the fish (tilapia, which, BTW, are pretty indestructible fish!!!).
They also had to supplement the 'fish water' with an aggressive foliar feeding program.
After almost 20 years struggling, TERRIBLE mismanagement and not that solid science either, lots of investors losing their shirts, they called it quits this past summer.
Stick with the stuff that you know works. Don't experiment on a crop that you can't afford to lose!
