Trout and Rockfish Tagging Studies on the Alabama Coast

A tagging program launched by the Coastal Conservation Association-Alabama (CCA) in 2017 provides inshore fishermen with more information on the movement and growth of speckled trout and rockfish according to David Rainer, an editor for the Department of Conservation and Alabama Natural Resources (ADCNR).

The TAG Alabama program, which is compiled and analyzed by the School of Marine Sciences at the University of Southern Alabama (US) and the Dauphin Island Sea Lab, calls on ACC members to mark the trout and rockfish and rewards anglers who file a report after the recapture of a tagged fish. .

CCA Alabama Executive Director Blakeley Ellis and U.S. graduate student Dylan Kiene have teamed up to provide instruction on safe tagging techniques and an update on tagging program data.

Kiene said speckled trout appear to be a constant traveler, but rockfish are unpredictable.

“We had a tagged redfish at Dauphin Island that got to Pensacola in about 30 days,” Kiene said. “We had a tagged redfish near one of the islands in the Mobile River that made it to Lake Pontchartrain in Louisiana in 130 days. On the other hand, we had a red drum which was performed three times by Captain Richard Rutland in the same place, the first time in 2017 and twice in 2018. “

Kiene said his program predecessor, Reid Nelson, observed little to no red drum movement in some spots.

“When Reid was doing acoustic work on the red drum, he was tagging fish in the Dog and Fowl rivers,” Kiene said. “One of the things you look for when doing acoustics is if a tag is constantly detected on the same receiver, you can assume the fish is dead. That’s what he thought until some of the fish were recaptured in the same spot. They were literally less than 100 yards from where they had been marked. They had enough food. They were happy.

“But the speckled trout are basically always on the move. You’ll catch them in the same places at the same time of year, but they’re still moving.

New to the Tag Alabama program is the male redfish brand that was presented to participants last week.

“With the red bull tags, once we get enough out of them, it will be really interesting to see if these fish go offshore where they are supposed to breed or go up in the delta,” Kiene said.

Ellis said CCA Alabama also recently approved funding for USA Marine Sciences to conduct an offshore red bull study with acoustic beacons and satellites.

Anglers participating in the TAG Alabama program can report tagging data through the Fishing Chaos app, at tags.usouthal.edu, which is best used on a computer, or 1-800 -372-5950. Kiene said the Fishing Chaos app scrambles the fisherman’s tag catch location data to keep this information private.

Since its inception, TAG Alabama has tagged 2,615 rockfish with 424 recaptures for a 16% recapture rate, Ellis said. For speckled trout, 2,364 fish were tagged with a recapture of 206 fish for a recapture rate of 8.7 percent.

“It’s actually a very high recovery rate,” Kiene said. “For larger tagging programs, a 4-5% recapture rate is what they normally see. This red drum recapture rate is extremely high. Rockfish are mostly homebody and tend to stay in the same areas. These areas also tend to be under high fishing pressure and more fish are caught. The speckled trout move a lot more and are a bit more difficult to catch compared to the red drum. “

The director of the marine resources division, Scott Bannon, said the tagging efforts are a big help in the management of these species.

“Coastal tagging programs provide valuable data on the movement of fish throughout the seasons in addition to providing data on catch effort,” said Bannon. “The data collected in tagging programs is valuable because it helps us in our management decisions. The more people who participate and the more fish are tagged, the better the flow of valuable data. “
