How to recognise it
The Black Grouper (Mycteroperca bonaci) is a robust fish with a streamlined body. It typically exhibits a dark brown to grayish coloration with lighter spots. The dorsal fin is long and continuous, while the anal fin is shorter. The mouth is large, with sharp teeth. The species it is most often confused with is the Goliath Grouper. The key detail that separates them is the size; Black Grouper generally does not exceed 50 inches in length, while Goliath Grouper can grow much larger.
Where it lives
Black Grouper is primarily found in the southeastern United States, particularly in Florida and the Gulf of Mexico. They inhabit both shallow and deep waters, typically ranging from 30 to 300 feet deep. They prefer rocky reefs, ledges, and wrecks, where they can find cover. In warmer months, they may move into shallower waters, while in cooler months, they often retreat to deeper areas.
When it bites
Black Grouper are most active from April to October. They prefer water temperatures between 70 and 85 degrees F. Early morning and late afternoon are the best times to catch them. Weather changes, such as a passing front or strong winds, can make them more aggressive. A full moon can also increase their feeding activity.
How to catch it
To catch Black Grouper, use a conventional rod and reel setup with a medium to heavy action. Recommended rigs include a Carolina rig or a jigging setup. Use live baits like pinfish or grunts, typically ranging from 4 to 8 inches. If using lures, consider jigs in bright colors like chartreuse or pink, weighing 1 to 3 ounces. Use a strong line, at least 50 to 80-pound test, and a sturdy hook size 5/0 to 8/0. Cast near reefs or wrecks and work the bait or lure by bouncing it off the bottom.
Size, age and the table
Anglers typically encounter Black Grouper in the 10 to 30-pound range. A trophy Black Grouper is generally considered to be over 40 pounds. They grow quickly, reaching sexual maturity around 3 to 4 years, and can live up to 30 years. The flesh is firm and white, making it highly sought after for eating. Handle them carefully to avoid injury, and if releasing, do so gently to ensure their survival.
