๐Ÿฌ ISLAMORADA TO NORTH CAROLINA IN 9 DAYS: ANOTHER DROP BACK TAG GETS RECAPTURED UP THE COAST

June 30, 2026. Another Drop Back tag just turned up about 700 nautical miles north of where it started. Nine days. That's how long the fish was out.

Billy Dunn (@harpoonbilly) tagged it on June 17 aboard Drop Back Charters out of 3 Waters Marina in Islamorada. On June 26, Brian Wilkins caught the same dolphin off the North Carolina coast, tag still in.

When we keep telling you the mahi are moving by, this is what we mean.

๐Ÿ“ˆ Billy Is on a Tear

This is the second long-distance recap off a Drop Back tag this summer, and the boat is still on top of the 2026 DRP charter leaderboard. Billy's not slowing down.

The migration corridor researchers have been writing about for years? This fish swam it in under two weeks. It's not theory anymore. It's a real fish, real tag, real angler on the other end, real date stamps. That's the whole point of putting in the work.


๐ŸŒŠ Why 9 Days Matters

The fish averaged about 78 nautical miles a day riding the western edge of the Gulf Stream up the coast. For anyone trying to manage this fishery, recaptures like this are about as clean a data point as you can ask for. They show how the Western Atlantic stock actually moves through a season, how connected the Florida and Carolina fisheries are, and how fast the Gulf Stream pushes pelagics north when conditions line up.

Single-state mahi rules don't work for a fish that crosses state lines in nine days. We've been saying it. The tags keep proving it.


๐Ÿ”ฌ The Dolphinfish Research Program

The recapture was logged through the Dolphinfish Research Program, run by Beyond Our Shores Foundation and led by Wessley Mener. They put tagging kits in the hands of charter captains and private anglers, then turn every recapture into public data that NOAA, state agencies, and university researchers actually use.

Sponsors keeping the kits in the water:

Guy Harvey Foundation ยท Grady-White Boats ยท AFTCO ยท Uncle JB's Outdoors ยท Grupo Coen


๐Ÿ‘Š Get Involved While You Fish

If you fish offshore, you can be part of this.

Big thanks to Brian Wilkins for reporting the catch, and to Billy for putting another tag in a fish that decided to take a long trip north.
