Context

Grouper is a common name for a group of marine fish in the family Serranidae, though some sources place them in Epinephelinae or Epinephelidae [2]. They are large, reef-associated fishes found in tropical and subtropical waters, and many species are valued as food fish [3]. Groupers are associated with hard structures like reefs, rocks, and ledges, and they are late-maturing, long-lived, top-level predators [3]. They are found in the Caribbean and western North Atlantic [3]. Groupers are prime food fishes and also used by anglers and spearfishers [3]. Some species can reach up to 3 m (10 ft) and weigh over 454 kg (1,000 lbs.) [1].
