The properly is subangular with the serrations at its angle being slightly enlarged and the upper edge of the gill cover is straight. The They are dark reddish brown on the upper part of the head and body, shading to paler pink on the underparts, they are marked with lighter spots and blotches across their body and there are darker margins to the fins.

This species has a maximum published total length of 125 centimeters (49 in), although they a more commonly found at lengths around 50 centimeters (20 in), and a maximum published weight of 23 kilograms (51 lb). The redgrouper's typical range is coastal areas in the western Atlantic, stretching from southern Brazil to North Carolina in the US and including the Gulf of Mexico and Bermuda.

Spawning occurs offshore between January and June, peaking in May. While primarily eating benthic invertebrates, the red grouper is an opportunistic feeder in the reef community.

The diet commonly includes mantid and portend crabs, juvenile spiny lobster, and snapping shrimp, with the occasional fish. The red grouper is of moderate size, about 125 cm and weighs 23 kg or more.

When aggravated (they are highly territorial) or involved in spawning activities, these fish can very rapidly change coloration patterns, with the head or other parts of the body turning completely white, and the white spots appearing more intense.

They start digging in the sediment from the time they settle out of the plankton and continue throughout their lifetime. They use their caudal fin and their mouths to remove debris and sediment from rocks, creating exposed surfaces on which sessile organisms actively settle (e.g., sponges, soft corals, algae).

The exposure of structure also attracts a myriad of other species, including mobile invertebrates and a remarkable diversity of other fishes, from bodies and butterfly fish to grunts and snapper. The lionfish Steroid Holsteins started invading red grouper habitat by 2008, from Florida Bay to the Florida Keys and offshore to Pulley Ridge, a despotic coral reef on the West Florida Shelf west of the Dry Tortugas.

Known for being extremely capable predators on small reef fish, scientists are very interested in determining the extent to which their invasion changes the functional dynamics of associated communities. Wikimedia Commons has media related to Epimetheus Mario.

Thanks to successful management under the Magnuson-Stevens Act, red snapper populations are rebounding and their range is expanding. On a regional level, any time the commercial sector does not land its quota, political pressures begin to ramp up from radical recreational fishing lobbying groups who push for reallocating commercial fishing quota and gifting it to recreational fishermen.

Why would these radical groups push for more lax management and reallocation when even recreational fishermen in the Gulf could only catch 35% of their quota in 2017? Solving the problem of a declining of red grouper population is not going to be an easy task, but I have confidence that our collaboration between industry, scientists, and managers, together with the best-available science mandated by Magnuson-Stevens, can successfully recover the red grouper fishery.

Paul Lough ridge is a commercial fisherman and owner of four boats out of Crystal River, Florida. He’s been fishing for over 25 years, starting with grouper and snapper, then expanding into stone crab.

“Adult gag grouper live in nearshore waters from coastal North Carolina south to Brazil and as well as in the Gulf of Mexico. Smaller gag are a lot of lighter in coloring, and have numerous dark brown, or charcoal, kiss-like marks along their sides.

“Adult gag grouper, live over on top of low- and high-profile hard bottom such as reefs or shipwrecks in waters between 60-250 feet deep,” said McLean Seward, fisheries biologist with the North Carolina Division of Marine Fisheries. “Young gag grouper will live in oyster reefs, estuaries and seagrass beds from Massachusetts to Cape Canaveral, Florida.

The coloration of red grouper helps to distinguish this species from gag with its head and body being dark reddish brown, shading pink or reddish or even pale pink along the lower part of its body,” Nash said. “In North Carolina, gag will typically spawn in February and have clear larvae, which then make their way into estuaries.

As water temperatures start to go down in the fall, juvenile gag will migrate from estuaries to offshore hard bottom habitat and larger members of their species,” said Seward. Seward noted that all grouper are considered protogynous intersex, “that is they start their lives as females, and a part of the population will morph, or make the change, to males as they get older.

Females start to reach sexual maturity when they are about 24 inches in total length and about 3 years old. They are voracious predators, and will feed on whatever they can capture including scad, snapper, grunt, sardines, crabs, porgies, shrimp and squid, said Seward.

“The red grouper is also a protogynous intersex and females are sexually mature by the time they reach 4 years old,” Seward said. Females typically will let go an average of 1.5 million pelagic eggs that stay at the surface for between 30-40 days before finally settling down to the bottom.

“ Red grouper may live to be as old as 25 years of age, with older specimens reaching a size of 32.5 inches and up to 25 pounds. They will feed on lobster, shrimp, octopus, crabs and fish that are found close to their preferred reef habitat,” Seward said.

Bottom fishing is the best way to catch gag grouper, using live bait, including squid and cigar minnows. Use a depth finder to find deep-water rock ledges, artificial reefs and shipwrecks, a gag grouper ’s favorite hiding place.

Recreational and commercial fishermen are required to use hooking tools when fishing for the snapper grouper species. “This prohibition does not apply to fish harvested, landed and sold before the annual catch limit is reached and held in cold storage by a dealer,” said North Carolina Division of Marine Fisheries Executive Assistant to Councils Steve Poland, who is also a representative with the South Atlantic Fishery Management Council.

Charter and head boat and commercial snapper grouper vessels must have National Marine Fisheries Service-approved sea turtle release gear and adhere to small tooth saw fish release protocol, Poland added. While populations of gag grouper have remained healthy, a 10-year effort to rebuild the red grouper stock has failed, leading to new, stricter rules and regulations taking effect this year.

Therefore, on Sept. 27, 2017, NFS sent a letter to the council stating that the South Atlantic red grouper stock was not making adequate progress toward rebuilding. So, NFS took steps in 2018 to immediately end overfishing of red grouper by reducing the total commercial and recreational annual catch limits, based on the acceptable biological catch recommendation from the council’s Scientific and Statistical Committee.

“For red grouper, this final rule extends the closure season formerly from January to April, to January through May of each year for the next ten years for the commercial and recreational portions off North and South Carolina, and establishes a commercial trip limit,” said Poland. This final rule establishes a commercial trip limit for red grouper harvested in the South Atlantic EEA of 200 pounds, gutted weight.

The trip limit is expected to help rebuild the red grouper stock by discouraging directed commercial fishing for the species, although it is not likely to substantially reduce the current level of commercial harvest of red grouper, according to the National Register. “The council selected a commercial trip limit that in combination with extending the spawning season cloture for red grouper off North Carolina and South Carolina would help keep down harvest numbers to help rebuild the stock,” Poland said.

You can help pay some cost by sponsoring a day on CRO for as little as $100 or by donating any amount you're comfortable with. Groupers are a species of fish that belong to the Epinephrine subfamily of the family Serranidae.

As telecasts, 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.

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 pinkish, grunts, blue runner, sardines, and mullet. The grouper is a lean and moist fish that has a mild flavor, and the flesh is firm and flaky.
