Except.... you don't want to risk getting chemicals from Raid into an aquaponics system... we need to find natural or organic solutions to bug spray...

I've said this before and I think there is merit in the fact that our fish can be the major source of organic pest control if we think oubout system design a bit differently? :scratch:

And the fish help control weeds by eating or uprooting them, and also feed on insect and snail pests. Interestingly, pesticide use on rice/fish farms is greatly reduced, if not eliminated. Although this is motivated by wanting to protect the investment in the fish, it really is a good practice both for farmers and the environment because scientific evidence shows that in nearly all cases insecticides are not needed in tropical irrigated rice.

There's also integrating Ducks and Rice Paddies -- "The Power of Duck" by Furuno.

Most of our rice paddies here are used as wetlands for migrating geese and ducks. But the Fish and Game are finding ducks dead from acute toxicity syndrome...go figure

Yes, ducks eat fish, snails, lotsa weeds, and even young rice shoots. It's all a timing game. Plant the rice, let it grow, introduce ducklings after the rice has a certain number of leaves....The book was pretty interesting, and the first good application of integrated cropping that I had ever seen. However, I didn't think my backyard would make a good rice paddie, and the community by-laws wouldn't have allowed me more than 2 ducks.

I had my grow beds set up in channels where fry would occupy the dug out center of the grow bed w/ continuous low flow and I never had pest problems after that. With an even deeper grow bed I could *theoretically* put up porous bulkheads r screens to hold gravel in a confined area with moats running around stocked with fish. It's really combining DWC with flood drain.
