The vast majority of the goliath grouper population is restricted to Florida waters. The proposal would allow the killing of 100 goliath groupers per year for 4 years, for a total of 400 goliath groupers. Goliath grouper, which were once known as jewfish, can grow to more than eight feet in length and 800 pounds. 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 overharvesting in the second half of the 20th century, before legislation was introduced in the U.S. to protect this species. Some species are also hermaphroditic in which the adult females may change to male at some stage of their life. Goliath grouper are found at depths of up to 150 feet (46m). Epinephelus itajara. From July through September, goliath groupers converge at special locations to spawn. Because of excessive fishing, the goliath grouper was considered commercially extinct in the US in the 1980s. The impressive goliath grouper is the largest member of the sea bass family found in the Atlantic ocean and one of the largest grouper species in the world, reaching sizes of nearly 900 pounds (400kg) and 9 feet (3m) in total length.

The goliath grouper is a saltwater fish that is also known as the “Atlantic goliath grouper” and “itajara”. This fish species was once prevalent in waters throughout the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico as well as areas of the Eastern Pacific and Gulf of California. Goliath grouper populations have substantially recovered since the harvest prohibition took effect. In 2002 Brazil set up a five year protection plan restricting the harvesting to only subsistence fishing (Iverson, 2006). It is estimated that over the past 100 years the area has lost over 44% of its mangroves and salt marshes due to heavy human development and traffic. As a result, goliath grouper (the continental U.S. distinct population segment) was removed from the species of concern list (71 FR 61022). However, there are factors that cast doubt on whether full re-covery has occurred that would support reopening a fishery (SEDAR 2011, 2016). Many are long-lived and slow-growing.

In 1993 a harvest moratorium was also put in place for goliath grouper in Caribbean waters. This has led to a severe decline worldwide in the goliath grouper population. They settle in shallow mangrove habitat, first in mangrove leaf litter, and then along mangrove shorelines. 1261 0 obj <>/Filter/FlateDecode/ID[]/Index[1247 30]/Info 1246 0 R/Length 79/Prev 856034/Root 1248 0 R/Size 1277/Type/XRef/W[1 2 1]>>stream The sizes targeted are breeding individuals.
