Sounds good. The fish would also make for a stable body of water too. no matter what you do to it, prudence still dictates that you'd have to boil/treat it somehow before comsuming it. I guess you could also cover it with something like window screen to keep critters out...

Aloha, out of curiousity, which island are you on? I spent a week in Kauai and 2 weeks on the big island this past summer. It was great....I'd go back to Kauai in a heartbeat. Truely beautiful. Enjoy your Paradise!
