Here in the big bend area of Florida, when I went in pursuit of 'Back Water Bone fish' aka mullet. I was told to enhance the chances of tussling with said wary species was by use of rolled oats and laying mash. Which is moisten to create a paste, from which meat ball size chum balls are formed. Having dispensed several of these enhancements into the general area assumed to be frequented by the subject at hand. One has only to wait and be prepared with a suitable fly rod, Id suggest a 6wt with at lest 6lbs fluoro carbon leader and a #8 furry foam fly and and a bobber......ah, er, make that strike indicator. One other note: Be prepared to set the hook just before the fish bites, they are quick on the take and refusal but not infallible, and great sport.
