Grouper
Mycteroperca microlepis · Serranidae
Also known as: Gag, Black grouper, Red grouper, Scamp, Yellowfin grouper
A heavy-bodied reef predator that lives on structure and tries to get back into it the moment it is hooked. Florida manages more than a dozen grouper species together under aggregate bag limits that differ between the Atlantic and the Gulf.
- Typical size
- 24–34 in, 8–20 lb for gag and red grouper
- Max size
- Gag over 50 in is exceptional; other grouper species reach far larger.
- Water
- Saltwater
- Best season
- Varies by species and coast, and is set by open-season dates rather than by the fishing — check FWC before planning a trip.
Identification
Thick body, large mouth, broad tail. Species are told apart by markings and tail shape — gag has faint wormlike marks and a slightly concave tail, red grouper a squared-off tail and blotched sides. Correct identification matters here because the rules differ by species.
Habitat & Range
Hard bottom, ledges, wrecks and reefs. Larger fish hold deeper; juveniles use inshore seagrass and structure.
Both Florida coasts, with different management regions and seasons on the Atlantic and Gulf sides.
Diet & Feeding
Fish, crustaceans and cephalopods, taken by ambush and an explosive suction strike.
Spawning & Reproduction
Several grouper species aggregate to spawn and are protected by seasonal closures — Atlantic species are closed 1 January to 30 April, and several Gulf species 1 February to 31 March seaward of the 20-fathom break. No agency spawning temperature was found, so none is published.
Spawning timing by location
Spawning tracks water temperature, so the calendar shifts with latitude and elevation. These break grouper timing down by state and water body.
- How to Catch Grouper in Florida
Grouper live in structure and run straight back into it, so the technique is heavy tackle and immediate pressure. The regulations are the hard part: Florida manages more than a dozen grouper species under aggregate bag limits that differ between the Atlantic and the Gulf, with closures that vary by species, by coast and even by depth.
How to Catch
A hooked grouper runs straight for the structure it lives in. Heavy tackle and immediate pressure off the bottom are the whole technique; give it three seconds of slack and you will be retying.
Best techniques
- Bottom fishing over hard structure
- Trolling deep-diving plugs along ledges
- Vertical jigging
- Live bait dropped to the bottom
Lures & baits
- Live pinfish
- Sardines and threadfin
- Squid and cut bait
- Heavy vertical jigs
- Deep-diving plugs
Best season: Varies by species and coast, and is set by open-season dates rather than by the fishing — check FWC before planning a trip.
