Would this work (aquaponics)

I was thinking of a large fish tank with gravel at a normal level for fish being seperated by a screen withe gravel piled high enough for a plant to be above the water with a aquarium bubbler near the bottom and on the other side with the fish having a regular aquarium filter I am also not planting any more than one plant on the side for the plant

Keeping sufficient amount of oxygen around the roots is the issue. I am not sure you will have adequate flow of water to keep the roots oxygenated. Try you set-up. If the both the fish and the plant survive, may be you can improve the concept.

I have seen a unit that used gravel beds for plants started in peat pots and potting medium then transplanted into the gravel beds. A sump pump would periodically flood the channels filled with gravel and plants.

There is a "self-cleaning" aquarium that has a 3 gallon fish tank with an air-lift tube that floods a growth tray in which baskets of gravel is keep constantly wet by about an half inch of water. A small air pump provides the lifting of water into the tray, excess water flows back into the aquarium. The kit is complete except for a live fish but that is taken care of with a certificate to buy a betta for $0.99 from Petco. The tank is available from "Back to the Roots" company that also sells mushroom growing kits.
