Redfish on the oyster bars, trout anywhere there's grass, flounder, Spanish Mack's sometimes, etc -
Don't bother to fish unless the tide's moving - Simplest rig is a popping cork and a jig tipped with shrimp or Gulp minnow -

Can also wade fish, some places - A cool way to do it, but please shuffle your feet - Stingrays !!
Over simplifying, I know, but you'll figure it out and catch something, I'm sure :~)
