The Atlantic goliath grouper or itajara (Epinephelus itajara), also known as the jewfish,{{Cite web|title=Renaming the jewfish|url=https://www.chicagotribune.com/news/ct-xpm-2001-07-23-0107230219-story.html|last=Tribune|first=Chicago|website=chicagotribune.com|date=23 July 2001 |language=en-US|access-date=2020-05-07}} is a saltwater fish of the grouper family and one of the largest species of bony fish. The species can be found in the West Atlantic ranging from northeastern Florida, south throughout the Gulf of Mexico and the Caribbean Sea, and along South America to Brazil. In the East Pacific it ranges from Mexico to Peru.[http://www.fishbase.org/summary/Epinephelus-itajara.html Epinephelus itajara (Lichtenstein, 1822)] FishBase In the East Atlantic, the species ranges in West Africa from Senegal to Cabinda. The species has been observed at depths ranging from {{convert|1|to|100|m|ft|sigfig=1|sp=us}}.

Etymology

The Atlantic goliath grouper was historically referred to as the "jewfish", and there are several theories as to the name's origin. A 1996 review of the term's history from its first recorded usage in 1697 concluded that the species' physical characteristics were frequently connected to "mainstay caricatures of anti-Semitic beliefs", whereas the interpretation that the fish was regarded as kosher food had little support.{{cite journal|last1=Gould|first1=R.G.|last2=Atz|first2=J.W.|year=1996|title=The trouble with "jewfish" or what's in a name|journal=Tropical Fish Hobbyist|volume=44|issue=12|pages=172–182}} Alternate explanations include derivation from the Italian word "giupesce", which means "bottom fish", or mispronunciation of the name "jawfish".{{Cite web|title=How the Jewfish Got Its Name|url=https://www.jta.org/jewniverse/2015/how-the-jewfish-got-its-name|access-date=2021-10-04|website=Jewish Telegraphic Agency|language=en-US}} In 1927, the New York Aquarium changed the fish's name to Junefish after protests.The Jewish Tribune, Aug. 5, 1927, p. 31 In 2001, the American Fisheries Society changed the name to "goliath grouper" after complaints that the nickname was culturally insensitive.{{cite journal|last1=Espinosa|first1=H.|last2=Findley|first2=L.

Description

Image:AtlanticGoliathGrouper.jpg

The Atlantic goliath grouper can grow to lengths of {{convert|2.5|m|ft|frac=2|abbr=off|sp=us}} and weigh up to {{convert|363|kg|lb|abbr=off}}.{{Cite web|date=2017-05-11|title=Epinephelus itajara|url=https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/epinephelus-itajara/|access-date=2021-10-04|website=Florida Museum|language=en-US}} The species ranges in coloration from brownish yellow to grey to greenish and has small black dots on the head, body and fins. Individuals less than {{convert|1|m|ft|0|abbr=off|sp=us}} in length have three to four faint vertical bars present on their sides. The species has an elongate body with a broad, flat head and small eyes. The lower jaw has 3 to 5 rows of teeth with no front canines. The scales are ctenoid. The dorsal fins are continuous with the rays of the soft dorsal fin being longer than the spines of the first dorsal fin. The pectoral fins are rounded and notably larger than the pelvic fins. The caudal fin is also rounded. The species typically preys on slow moving fish and crustaceans.{{Cite journal|last1=Artero|first1=C|last2=Koenig|first2=CC|last3=Richard|first3=P|last4=Berzins|first4=R|last5=Guillou|first5=G|last6=Bouchon|first6=C|last7=Lampert|first7=L|date=2015-04-15|title=Ontogenetic dietary and habitat shifts in goliath grouper Epinephelus itajara from French Guiana|journal=Endangered Species Research|volume=27|issue=2|pages=155–168|doi=10.3354/esr00661 |doi-access=free}}

Habitat

Adult individuals are typically found in rocky reefs, wrecks, artificial reefs, and oil platforms. The species can also be found in coral reef habitats, but are much more abundant in rocky reef environments.{{Cite journal|last1=Bueno|first1=L. S.|last2=Bertoncini|first2=A.

Reproduction

The Atlantic goliath grouper has a longevity of 37 years and reaches first maturity after 6 years, which leads to an estimated generation length of 21.5 years. The species has been hypothesized to be protogynous hermaphrodites, but this has yet to be confirmed.{{Cite journal|last1=Koenig|first1=Christopher C.|last2=Coleman|first2=Felicia C.|last3=Malinowski|first3=Christopher R.|date=2019-10-04|title=Atlantic Goliath Grouper of Florida: To Fish or Not to Fish|url=http://dx.doi.org/10.1002/fsh.10349|journal=Fisheries|volume=45|issue=1|pages=20–32|doi=10.1002/fsh.10349 |s2cid=202017187 |url-access=subscription}} Males become sexually mature at around {{convert|115|cm|in|sp=us}} in length, and at ages 4–6.

The species has relatively small spawning aggregations of less than 150 individuals with no evidence of spawning outside of these aggregations.{{Cite book|last=Sadovy Y.|first=Eklund A.M.|date=1999|title=Synopsis of biological data on the Nassau grouper, Epinephelus striatus (Bloch, 1792) and the Jewfish, E. itajara (Lichtenstein, 1822) |series=NOAA Technical Report NMFS 146, and FAO Fisheries Synopsis 157 }}

Conservation

Atlantic goliath groupers are highly susceptible to rapid population decline due to overfishing and the exploitation of spawning aggregations. The species has a brief annual larval settlement period, making the species' abundance extremely vulnerable to outside factors such as poor weather conditions.{{Cite journal|last1=Cheung|first1=WWL|last2=Sadovy|first2=Y|last3=Braynen|first3=MT|last4=Gittens|first4=LG|date=2013-02-22|title=Are the last remaining Nassau grouper Epinephelus striatus fisheries sustainable?

The species was previously classified as critically endangered in 2011 and is currently classified as vulnerable in 2021. A 2016 stock assessment model indicates that there has been an absolute population reduction of around 33% from 1950 to 2014. There has been a complete moratorium on the fishing of this species in continental U.S. waters since 1990 and in U.S. Caribbean waters since 1993.

In October 2021, Florida Fish and Wildlife proposed to allow the fishing of 200 juvenile goliath grouper per year including up to 50 from Everglades National Park. Recreational fishing of the species would be permitted in all state waters except those of Palm Beach County south through the Atlantic coast of the Keys.{{Cite web|title=FWC approves a draft proposal for limited, highly regulated fishing of goliath grouper|url=https://content.govdelivery.com/accounts/FLFFWCC/bulletins/2f648bf|access-date=2021-12-06|website=Florida Fish & Wildlife Conservation Commission|language=en}} The proposal was approved in March 2022, with the Florida Fish and Wildlife Commission planning to issue 200 permits per year through a lottery system, which came into effect in the spring of 2023.{{Cite web |date=March 3, 2022 |title=FWC approves limited recreational harvest of goliath grouper in state waters |url=https://myfwc.com/news/all-news/goliath-comm-322/ |url-status=live |archive-url=https://web.archive.org/web/20230226185040/https://myfwc.com/news/all-news/goliath-comm-322/ |archive-date=February 26, 2023 |access-date=2023-02-26 |website=Florida Fish And Wildlife Conservation Commission |language=en}}
