The smallest here is just over 22 in. legal . ...65 lb. braid with a swivel... 6 ft. of 80 lb. mono...a # 2 planer (sea striker ) around $10...30 ft. of 50lb. mono after that with a swivel in the middle...and a 6 in. Tsunami Pro swim shad ( about $6 for a four pack).
Start out around bouy # 1E ( out from Bahia Beach/ Cockroach bay area, a couple of miles from the south shore)...The main channel is around 50 ft....stay in the 35 ft depth on the shoulders...Go from 1E south to the Skyway bridge trolling from 3 to 5 mph. depending on tide flow. Around 100 to 150 ft. back from the boat. Set the drag and this will snatch them out of their holes. Google up sea striker and it will show planer use.
You can fish the Manatte channel but it's much harder to stay on the slope...you need a good depth machine...pay little attention to the fish alarms unless you have a good unit and know what your doing.
Take beer and a sandwich...The bite seems to happen after mind numbing time and then it's hot for two hours..moving tide is good...good luck...
