If you have a good cast net there is usually plenty of bait outside the west jetty. I use a 10' 1/2" 1.5 lb. Would probably go with a 8 ft next time I buy. Do not get near the rocks or you will loose it. Usually one good cast will get me all I need. Also may get some cigars at the bouy with a small sabaki rig. I haven't tried a pin fish trap but I'm sure it would work.
Go to Alabama DNR website, saltwater fishing and there are public spots published as well as fishing lincenses. PM your email and I will send a spreadsheet sorted by distance from OB. Better hurry I'm leaving for there in the AM.
Nipple and elbow on the 100 ft line have been good for wahoo, whites and dolphin. They are about 45 staute miles out. Maybe troll to the spur from there. Stop by J&M Tackle on canal road for tips, gear and a map. It is about a mile before the intersection that heads toward the beach. Also top gun Tackle by Winn Dixie can help out.
Blue crab can be readily caught with traps in 6+ ft of water.
The rigs west usally hold king, spanish and bottom fish. Just head WSW from OB and look for them. Head back through Mobile Bay, watch out for Dixie Bar to the east. Follow the ICW to Wolf Bay. Fuel up at Lulu's then stop at Pirate's Cove for a cheese burger and drinks. Shirt and shoes not required. Dogs allowed. 30 19.3 N 87 32.0 S is the location based on my t-shirt I got there. Between red bouy 58 and 60.
Most importantly, don't tell anybody where you are from..............
