Groupers are a species of fish that belong to the Epinephelina subfamily of the family Serranidae. As teleosts, all types of grouper have a stout body and a large mouth and are weak swimmers. However, once caught, a grouper will put up a vicious fight and use their vast bulk to full advantage.
Here are a few common types that you may encounter and what you need to know about each to increase your chances of getting a large catch. The fish in this species are hermaphrodites i.e., they mature as females and can turn into a male later on. The male differs from females in appearance, as well. Plus, grouper fish size matters when it comes to fishing gear and tactics.

How to Catch Grouper
Irrespective of the types of grouper you wish to target you can catch large ones with lures, live and dead bait. If you are casting in the shallows, use jerk bait and retrieve it erratically to lure the fish out in the open. You will need heavy tackle, especially if there are a lot of rocks under the water where you are fishing and a braided line that can withstand the powerful pull of a caught grouper.
If you are using spinning tackle, make sure that the reel is heavy enough to withstand an 80 to 100-pound test mainline and a low gear ratio to give you more control. This tackle will come in handy when the panicking grouper fish tries to swim under a ledge to break the line.
For live bait, use pinfish, grunts, blue runner, sardines, and mullet. Take a selection of these with you so that you can give the fish a full menu. Bridled bait will set in nicely in the mouth of a giant grouper.
Always check your local grouper regulations.
