Population [top]

Population:This species can be common and locally abundant in at least part of its range. Catch of mojarras in the Bahamas consists largely of this species and Gerres cinereus (Newman et al. 2007). It is one of the top three most abundant species in the North Sound lagoon at Bimini, Bahamas (Newman 2003, Jennings et al. 2012). It is a dominant species in the mangrove lagoons of St. Croix (Mateo and Tobias 2004). It is also abundant in high energy inlets and beaches off southeast Florida.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This demersal, marine species occurs in tropical climates where it is associated with clear to slightly turbid water in shallow protected bays and open beaches over a variety of substrates (Böhlke and Chaplin 1993, McEachran and Fechhelm 2005). It apparently does not enter estuaries or freshwater and may occur in slightly deeper water and on banks that are farther offshore than those usually inhabited by Eucinostomus argenteus (Robins and Ray 1986). In the Bahamas, it is more abundant over sand and seagrass than in mangroves (Newman et al. 2007). It feeds on crustaceans. Adults of this species are not common along the shore and are thought to spawn in deep water near the coast. Its maximum size is 15.9 cm SL or 20 cm TL (Robins and Ray 1986, McEachran and Fechhelm 2005).

Use and Trade [top]

Use and Trade: This species may be utilized for bait.

Threats [top]

Major Threat(s): The most likely impact on this species is the beach modification programs occurring off Florida, however, this likely only impacts subpopulations on a localized basis (Kilfoyle et al. 2013).

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place.
