One of the hardest fighting fish pound for pound that are a challenge for any experienced angler due to the fact that they hangout in structure such as rocks and wrecks and you have to rip them out or they will break your line. We prefer to throw big lures or plugs for the bigger gags in the 24”+ range with the drag almost completely locked down simply because with live bait they are nearly impossible to pull out of where they are hiding.
Go to any restaurant in Florida and they will have grouper on the menu because they are excellent table fare. Grouper start their life as females and turn into males around the age of 8 years old. With a life expectancy of 30 years old. The best months to target them inshore would be from September all the way to February.
