Geographical Distribution

Launch the Aquatic Species Distribution map viewer

Tropical western Atlantic Ocean throughout most of the Caribbean Sea from Cuba southward to northeastern Brazil. Most abundant on the continental shelf off Honduras and Guayanas; less common around the Antilles where it is confined to deeper water.
Habitat and Biology
Inhabits rocky areasbetween about 30 and 160 m depth, most commonly in depths between 70 and 120 m.Feeds mainly on fishes, shrimps, crabs, cephalopods and planktonic items.

Spawning occurs mainly during spring and summer.  The von Bertalanffy growth coefficient (K) and exponential rate of mortality (M) were estimated as 0.09 and 0.35 respectively for the northern Brazil population (Menezes & Gesteira, 1974). Estimated maximum age: 12 to 18 years.
Size
Maximum total length about 100 cm; common to 65 cm.
Interest to Fisheries
Of limited interest to commercial fisheries. In 1983 a total catch of 7 531 metric tons was reported to FAO (Fishing Areas 31 and Fishing Areas47). Caught mainly with bottom longlines, handlines and bottom trawls; also taken with gillnets.
Flesh of good quality, marketed mainly fresh.

Remarks
Frequently confused with L. campechanus. Also referred to as L. aya by past authors, but Rivas (1966) provided evidence that indicatesBodianus aya Bloch (1790:45) is not a lutjanid, but probably a sciaenid.
