Not the best time of year to be fishing down there....we usually stay out on the islands (captiva and North Captiva) and fish the passes. lots of fun. Gag grouper on the outgoing tides. a 30"er will feel like you have hooked into a 20lb fish and great eating too. We have stayed in cape coral before and fished the caloosahatchee (sp?) caught a couple of lady fish, snapper and too small grouper. Not much of a chance of getting a tarpon this time of year. we bring our boat down with us so we usually head to the passes and the bridge pilings. tons of dolphins. not sure if I can help with much but feel free to pm me with any questions about the area. If you are mobile head over to sanibel island, ther is a bar there called the Lazy Flamingo right accross the street they recently opened an old pass and the nutrients now entering that part of the gulf from the stirred up sound are attracting all sorts of goodies. if i was shore fishing thats where i would be. something along the lines of an old fashion pickerel rig with a couple of shrimp and you are good to go.
I think trout is out of season right now, may want to check fl regs...
good luck!
