This is all very encouraging and is giving me a boost to plant veggies in my floating island/raft. The raft is filled with potting soil about 4 inches deep and draws constant water from the pond with wicking ropes in the bottom, but just the holes w/o ropes may wick by themselves. It grew Petunias really well last year in my vegetated pond, which produces oxygenated water and is stocked with minnows, tadpoles and bluegill that fertilize the water. I can see no reason to fertilize the soil and just plant.
I can see bull frogs and bluegill being a food source by-product protein part of the system, and the frogs and bluegills keeping bugs fattening them while helping to keep the produce somewhat free of bugs. Last year once the island was planted there was no other work involved and expense free. My dog Dollie probably has taken enough bullfrogs out of the pond to fill my freezer and the bluegills I see look fat. It does seem too simple doesn't it.
