Sport Fish Tag and Release Program
The Gulf Coast Research Laboratory (GCRL) has been a leader in angler-cooperative marine sport fish tag and release since 1989. Thousands of volunteer anglers across the northern Gulf of Mexico and the southeastern United States have assisted GCRL researchers with investigating the movement patterns of important fishery species: cobia, tripletail and spotted seatrout (speckled trout). Download this brochure for details on the tag and release program.
The Sport Fish Tag and Release Program relies on the fishing community to tag fish and report recaptures, which is vital to determining movement patterns and growth rates. The involvement of anglers in these activities provides information which is difficult to obtain by other means.
Example of data obtained from tagging program.
Tagging Kits
Participating anglers are provided with a free tagging kit, which includes tags, tag cards, a tag applicator, instruction booklet and a pencil. The type of tag used for these programs is a “dart tag.” The tag consists of a polyethylene streamer bonded to a nylon dart head made of non-toxic materials. The tag is inserted below the spinous dorsal fin of the fish. When properly inserted, the tags produce no long-term injury and can remain firmly implanted for years. Each tag is attached to a corresponding data card, on which the requested information about the catch is to be recorded. Anglers are asked to mail their data cards to the GCRL within a reasonable time period so the data can be archived.

How to Participate
Anglers interested in tagging any of the target species should call or email Read Hendon at 228.872.4202 or read.hendon@usm.edu to request the free tagging kits.
If you Catch a Tagged Fish
If you catch a tagged fish, please record the tag number, the location, and date. Measure the length of the fish and note it's overall condition. Provide the information to Read Hendon at 228.872.4202 or read.hendon@usm.edu. While anglers are encouraged to release tagged fish after taking the tag number and measuring them, no regulations prohibit keeping legal tagged fish.
Species Targeted
Cobia(Also called lemonfish, ling and cobio) |
More than 1,600 anglers have received tagging kits for cobia since 1989. A total of 15,650 cobia have been tagged and released with 1,004 of those fish (6.4 percent) reported as recaptured through 2008. |
Spotted Seatrout(Speckled Trout) |
The focus of the Spotted Seatrout Tag and Release Program has been on fish caught in Mississippi. Due to a lack of data on the movements of larger fish, we ask that anglers only tag Mississippi-caught specks 14 inches total length or longer Of the more than 17,000 spotted seatrout tagged and released from 1995-2008, approximately three percent were recaptured and reportedl. Tagging results revealed that more than 90 percent of tagged fish had moved less than 10 miles upon recapture. Only three fish had traveled 30 miles or more. This supports the Gulf-wide notion that spotted seatrout are generally resident fish within the coastal waters of each state.

Tripletail(blackfish)  Tripletail Life History Study |
More than 2,000 tripletail have been tagged and released from 1996 through 2008. Of those fish, 229 have been recaptured, resulting in an astounding recapture rate of 11.1 percent. Due to the efforts of dedicated anglers, most of the information gained through this research pertains to tripletail occurring in Florida waters, as 78 percent of all fish have been tagged along the Florida Peninsula. Tagging data show that tripletail occur year-round in Florida waters but only occur seasonally in the northern Gulf, having been tagged from May to October in Alabama and Mississippi waters.
