Their abundance has severely declined since the mid-20th century primarily because of direct harvest by commercial and artisanal fisheries. Outside a known population in Bahia Magdalena, there is no published evidence of gulf grouper along the Pacific coast of the Baja California peninsula.
Adult gulf grouper are mainly found around rocky reefs, underwater mountains, and kelp beds. Gulf grouper are also likely protogynous hermaphroditic, which means that they mature as females and later transition into males.
Adult gulf grouper gather in large groups to reproduce once per year. They gather at reefs and underwater mountains and form spawning aggregations from April to June.
Activities that may degrade their habitat include the release of contaminants, such as urban runoff, wastewater, or oil and gas spills. Pollution can also reduce the amount of oxygen in the water or deliver chemicals that are toxic to these fish.
Physical barriers, such as shoreline and offshore development can also threaten gulf grouper by limiting their access to important breeding or feeding areas. Overfishing Direct harvest of gulf grouper, especially at spawning aggregation sites, is the biggest threat to the species.
This means that there are fewer male groupers left in the oceans, which makes reproduction more difficult. Over time, the department plans to convert content from all PDF sources into species profiles.
As a result, Goliath grouper (the continental U.S. distinct population segment) was removed from the species of concern list (71 FR 61022). Scientists from our Southeast Fisheries Science Center are working to understand the changes that have occurred in coral reef ecosystems following the loss of top predators, such as groupers.
From 1997-2005, our researchers collaborated with Florida State University's Institute for Fishery Resource Ecology (Dr. Chris Koenig and Dr. Felicia Coleman) to monitor the status and recovery of Goliath grouper. This Goliath grouper research program investigated juvenile and adult Jewish abundance, distribution and migration patterns; their age and growth; and their habitat utilization.
With the help of Don Maria we have tagged over 1,000 adult Jewish and have observed aggregations of Goliath grouper in both the Gulf of Mexico and more recently, the South Atlantic. Posters created by the Center of Marine Conservation help disseminate information about our project and its requirements, highlighting our tagging study and the morphology of Goliath grouper.
Given that these groupers were afforded protected status, researchers worked to utilize and develop novel non-lethal techniques to procure and analyze biological samples for life history information. Researchers have also determined that soft dorsal rays hold promise for aging older fish (Marie et al., 2008).
These casualties, resulting from red tide, gave our biologists a unique opportunity to collect a multitude of biological samples, without having to sacrifice healthy animals. From these decomposing carcasses, biologists were able to record length for use in an age/length relationship, and were able to extract monoliths and remove dorsal spines and rays for comparison of hard parts in age and growth analysis.
Tissue samples were also removed and sent to the Florida Marine Research Institute, so they could evaluate the level of red tide toxin. The sampling trip gave these biologists an opportunity to educate the curious beach goers about red tide and Goliath grouper (a few of which had been misidentified as baby manatees).
Attempts to evaluate the data needed to assess the status of these depleted stocks and develop rebuilding plans present unique challenges. In 2010, the Florida Fish and Wildlife Conservation Commission and NOAA Fisheries convened a benchmark Goliath grouper assessment for the continental U.S. population.
This project would not have been possible without ongoing collaboration with researchers from Florida State University, Everglades National Park, and the recreational fishing and SCUBA diving communities.

Black grouper at Flower Garden Banks National Marine Sanctuary. U.S. wild-caught black grouper is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.
Fishing gears used to harvest black grouper have minimal impacts on habitat. The groupers complex is not subject to overfishing based on 2019 catch data.
Black grouper have large, powerful jaws that they used to ambush their prey. They also have teeth plates inside their throat that prevent prey from escaping after being swallowed.
Black grouper are found in the western Atlantic from Massachusetts to Brazil. They are particularly associated with the southern Gulf of Mexico, Florida Keys, Cuba, the Bahamas, and throughout the Caribbean.
Annual catch limits are used for black grouper in the commercial and recreational fisheries. Both the commercial and recreational fisheries have size limits to reduce harvest of immature black grouper.
The commercial and recreational fishing seasons are closed from January through April to protect black grouper during their peak spawning period. Year-round and/or seasonal area closures for commercial and recreational sectors to protect spawning groupers.
Groupers are managed separately by commercial and recreational sector in Puerto Rico. Seasonal closure for black, red, tiger, yellow fin, and yellow edge groupers from February 1 through April 30.
The red grouper is one of the most important species of fish caught off the southeast coast of the Unite States. Color is variable and can change, however the head and body are generally dark brown with a reddish cast, shading to pink or reddish below, with pale poorly defined pale areas and small black spots around the eye.
I’ve watched fishing shows where anglers share grouper fishing tips and use whole, live sting rays as bait and seen video of a big brute inhaling a 3-foot shark that an angler was trying to reel in near his boat. Again, like bass fishing that action of bottom bouncing, or jigging can trigger a reaction bite.

When an important species is overfished, it doesn't just affect the ability of that fish population to reproduce; it can throw the entire ecosystem off balance. And overfishing of algae-grazing parrot fish in the Caribbean has led algae to proliferate and damage coral reefs, which are essential to healthy fish populations.
Managing fisheries to be more sustainable is one of the most effective tools that we have to influence both the immediate and long term health of our oceans. That’s why TNC is launching a new program to support a healthy snapper and grouper fishery in Florida.
TNC has been involved in sustainable fisheries in other parts of the United States and around the world for many years, including working with fishermen off the Oregon coast to modernize data collection and improve monitoring, and testing new methods to reduce by catch in the longline tuna fishery in the Pacific island nation of Paley. In Florida, recreational anglers represent a larger share of the overall user group than in other parts of the world.
Recreational fishing in Florida generates an estimated $6 billion in annual expenditures, compared with $15 million for all other South Atlantic states combined. Of the many fish harvested in these waters, the National Oceanic and Atmospheric Administration (NOAA) scientists have identified snapper and grouper as being the most vulnerable to overfishing.
These long-lived species are often associated with hard-bottom habitats, meaning both shallow and deep-water coral reefs, where they serve an important role as predators, keeping populations of smaller fish in check. In the long term, our goal is to achieve snapper and grouper stocks that are healthy, sustainable, and serve their important role in the ecosystem by 2045.
Getting these fish populations back on track will be an important step to restoring the health and function of coral reefs in Florida, preserving the rich biodiversity of the region's waters, and making sure that these ecosystems are protected for the future. One of the major issues affecting snapper and grouper species is barotrauma, or injuries caused by a rapid change in pressure.
Just as divers get the bends if they surface too quickly, when a fish is pulled up from deep water, the compressed gas in its body expands. This change can cause its eyes to bulge, its stomach to pop out of its mouth, and bubbles to form in its heart and brain.
If the fish doesn’t die from these injuries after being released, the extra gas in its body will cause it to float like a cork, making it vulnerable to predators and unable to swim down to a safe depth. These simple tools use various techniques to quickly pull the fish back down to the proper depth and release it.
Others latch onto the mouth with a blunt hook, or trap the fish in a container, and are released manually with a quick jerk of the line. Whichever version the angler uses, descending devices significantly reduce discard mortality rates.
These devices are also much safer and more effective than venting the fish by puncturing its swim bladder, a common practice to reduce mortality. In addition to improving the overall health of snapper and grouper species in our waters, a second major goal of our fisheries program is to assist in gathering data.
In an effort to increase access to accurate information, TNC will be collecting data regarding overall awareness of descending devices among recreational anglers, whether and how they are being used, and prevalent catch-and-release practices. Florida’s fishermen care about the snapper and grouper fisheries and understand their value, which is why we’re partnering with boat captains, social media influencers and other leaders in the recreational fishing community to help spread the word about the importance of descending devices, and to educate anglers on the benefits of proper handling technique.
By educating others, using descending devices and helping to collect data, we can decrease mortality rates, help restore snapper and grouper stocks in Florida, ensure there ’s enough fish to maintain a healthy ecosystem and support a robust recreational and commercial fishing industry for years to come.
