Kingfish
Kingfish will be just off the beach feeding on mullet and menhaden. Shrimp boats dumping their by-catch offer an opportunity to catch 40-pound kingfish. Chumming will also bring kingfish to the boat. Bait of choice includes mullet, menhaden, ribbonfish, blue runners, and goggle eyes.
Tarpon 
Some of the best spots for tarpon have been from Ponte Vedra Beach to the mouth of the St Marys River and off the beaches of Amelia Island, and off the Golden Isles of Southeast Georgia.
Redfish & Trout
Redfish can be found in shallow water on an outgoing tide early in the day. Sometimes you will be able to sight cast these fish. Use shrimp or finger mullet on a light jig or as an alternative use Gulp Mullet or Shrimp or Fishbites Fight Club Grub. After the day begins to warm about midmorning move to deeper water. The edge of the channel in the St. Johns River, St Marys River, or Nassau Sound should be good producers. Use cut mullet, ladyfish or crab fished on the bottom with a fish finder rig. These fish can be over 30 pounds so heavy tackle will help keep the fish alive.
On a morning with a rising tide, it is better to fish with a float in the backcountry creeks. Float a shrimp or live mullet along the edge of the grass line with the current. In addition to catching redfish, you stand a good chance of catching trout to 5 pounds this time of year or even a tarpon.
Flounder
Use a jig and shrimp or mud minnow fished slowly on the bottom for flounder. Work creek mouths with mud or sand bottom. The jetties by Ft Clinch have always produced good flounder fishing. Remember that the regulations have changed.
5 fish limit
14″ total length
Closed season from October 15th to November 30th.
Surf Fishing
Watch for an East wind to push cooler water and finger mullet into the surf. With the finger mullet will come redfish, trout, ladyfish, bluefish, and jacks. This will get your surf fishing warmed up for the fall mullet run.
