Went out for an early inshore troll. Got to the HA around 6am and saw dolphins flying around everywhere, jumping out of the water and getting the **** out of dodge real fast. Then we saw why, Jaws. Big shark on the surface. I couldn't get a good look at him though b/c he dove down. The dorsal fin to the tail fin had to be at least 7 or 8ft. Put the lines in though wasn't much hope of catching anything with the big shark around but figured why not. trolled around the HA for a few laps then headed towards the area between the Glory and Mudhole as it looked like that is where the temp break was. A mile south of the HA we get the lightest hit I've ever gotten on a superbar I had out, turned out to be about a 1lb mahi. Smallest little thing. After that trolled the flats area north of the glory, into the hole, back towards the mudhole, etc. Nothing. Had porpoise around us. Other guys had some bluefish and had flying fish around them but not tuna.
