In Florida, hatchlings join their brethren in safe spaces near coastal mangrove estuaries and spend their first six years of life dining exclusively on fish, crabs, and shrimp before heading out to open waters. The Goliath grouper grows slowly, attaining maturity around age 20-25, which is why it is important to manage fishing of the species; they need the chance to reach adulthood to reproduce in order to create a sustainable fishery.

The Goliath grouper is a key species in Florida waters because their presence is an indicator of health for local coral reefs. This particular species feeds by swallowing their prey whole, creating negative pressure that quickly them to bring in whole invertebrates, fish, and even smaller sharks.

Many grouper, manatees, and turtles were found washed ashore on Southwest Florida beaches during the red tides in 2003 and 2005. The good news is that as of 2006 the Goliath grouper ’s population had improved and was considered to be on a recovery trajectory due to the careful protection by NOAA Fisheries.

Fish, mixed species, cooked, dry heat The Goliath grouper, which may grow up to 8 feet (2.4 m) in length, is listed as “Critically Endangered” on the International Union for the Conservation of Nature (IUCN) Red List, due to over harvesting in the second half of the 20th century, before legislation was introduced in the U.S. to protect this species.

The Goliath grouper reaches a length of 8 feet (240 cm) and the largest published weight is 1003 lbs. The juvenile Goliath grouper, which is less than 39 inches (100 cm), is tawny or yellowish-brown in color with irregular darker brown vertical bands.

The larger adult fish is gray or greenish with pale blotches and smaller dark brown or blackish spots scattered over the upper part of its head, body and pectoral fins. The Goliath grouper is capable of producing a loud booming noise, which may be used to defend territory or during courtship.

The Goliath grouper feeds primarily on crustaceans, especially spiny lobsters, as well as turtles, fish and stingrays. This species is an ambush hunter that feeds during the day, with increased activity during the low-light periods of dawn and dusk.

This is accompanied by rapidly expansion of its jaws and flaring of the gill covers which create a vacuum that sucks the prey into its mouth. The Goliath grouper occurs in the western Atlantic from Florida to southern Brazil, including the Gulf of Mexico and the Caribbean.

Populations began to decline in the 1960s when recreational SCUBA divers would swim up to the fearless fish and spear it at close range. The Goliath grouper exhibits territorial behavior near its sheltered home in a cave or wreck.

This consists of a “threat display” to intruders by opening its mouth wide and shaking its body or producing a loud booming sound (see below). The Goliath grouper will travel many miles during one or two months each year to mate in huge spawning aggregations at traditional breeding grounds.

As the male approaches the female, its entire forebode, from the pectoral fins forward, turns pale, contrasting sharply with its dark rest of the body. The eggs hatch into transparent larvae that quickly develop long spines and a large mouth.

After drifting with the current for 25 to 45 days, the one-inch larvae settle to the bottom in shallow-water mangrove habitats where they hide while completing metamorphosis into juveniles. Due to short dive times at depths of 100 feet or more, there have been few recorded observations of the courtship of the Goliath grouper.

Conversely, Fat-soluble vitamins can be stored in the body for several years, so it takes longer to develop deficiency.
