One of my favorite presentations, bounce a jig on the bottom much like speckled trout fishing on the Causaway. Cast it out there, let it hit the bottom, bounce it up a foot or two, let it sink, repeat. Usually get the hit on the fall. Keep the line tight, and watch for any stops or side to side movement. The best time to use this technique is spring, in shallow canals 4 to 6 ft deep.
