They call those setups aquaponics. It's a really cool system and one I would love to have as an indoor farming setup some day when I can finance it.
Currently I die a little inside when I do aquarium filter cleaning and water changes. The amount of nutrientns I cannot re-use is saddening. So much good fish poopy going to waste.
Another cost consideration is the food safety licensing and whatnot you would need to have.
If you pick up coco coir (an inert medium for hydroponics when plants need a bit more rooting structure) you can dump that sludge right over top to water whatever plant you have growing in it.
If it ends up getting kinda gross, take it outside and hose a bunch of water through it to rinse it, good to continue. But mostly it just causes the coir to break down a bit faster than it otherwise would, due to the bacteria, so this is basically like adding compost continuously.
Doesn’t work for every plant, but does work for a lot of them! I have potatoes in such a setup right now, and it’s pretty swanky.
I use my used aquarium water for our fruit trees, and they love it.
