Ten- to twenty-pound (5 to 10 kg) fish are common. The world record is 80 lb 6 oz (36.45 kg). The gag grouper is a bottomfeeder and is often caught by fishermen seeking bottom-dwelling species such as snappers. It has flaky white meat that is considered quite delicious.
Members of this species are known to be protogynous hermaphrodites, schooling in harems with the most aggressive and largest females shifting sex to male, probably as a result of behavioral triggers, when there is no male available. Commercial and sport fishing have created tremendous selective pressures against the largest animals, typically male, restricting the reproductive capacity of the entire breeding population. Recently, a small closure in the Gulf of Mexico was established to provide this and other species a refuge from commercial fishing pressure, however, this data is highly in dispute and is currently being challenged for inaccuracies. They are found in hard bottom with an uneven bottom. Things they like are ledges,rocks,coral reefs,etc. They also like structure. Like wrecks,artificial reefs, and sunken barges.
