Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2015
Date Assessed: 2012-08-20
Assessor(s): Smith-Vaniz, W.F., Williams, J.T., Pina Amargos, F., Curtis, M. & Brown, J.
Reviewer(s): Cox, N.A.
Contributor(s): Sylla, M., Nunoo, F., Camara, K., Carpenter, K.E., Djiman, R. & Sagna, A.
Facilitator/Compiler(s): Comeros-Raynal, M., Polidoro, B. & Strongin, K.
Justification:
This pelagic species is widely distributed and abundant where it occurs in shallow, clear waters around coastal reefs. It is targeted by minor commercial fisheries in the Caribbean, but this is not expected to impact its population on a global level. Therefore it is assessed as Least Concern.

Geographic Range [top]

Range Description:Caranx ruber is widely distributed in the western Atlantic from New Jersey south along the U.S. coast, Bermuda, the Bahamas, and throughout the Gulf of Mexico and Caribbean Sea (Smith-Vaniz 2002). It has also been recorded from Trinidade Island (Simon et al. 2013). Records from Ascension and St. Helena Island are likely vagrants (Edwards 1993), however, Wirtz et al. (2014) reports it as a resident of Ascension Island.

Population [top]

Population:Caranx ruber is well represented in museum collections and can be locally abundant (Fishnet 2 Portal, accessed 19 July 2012). This species is the most abundant Caranx (Carangoides) species in the West Indies (Smith-Vaniz 2002). In Jamaica, this species comprises the bulk of the jack commercial catches. It is abundant in surveys and in the fishery. In the eastern coast of northeast Brazil, this species was found to be uncommon shallow over-shelf deep reefs and shelf-edge deep reefs from 5-40 m (Feitoza et al. 2005).
Current Population Trend:Unknown

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits shallow, clear waters around coastal reefs. It occurs mostly in small to large schools and is occasionally solitary. Juveniles are associated with Sargassum seaward rafts. Prey items include fish, some shrimp, and other invertebrates. Feeding habits vary according to growth and season, juveniles feed on zooplankton and adults are piscivores (after 30 cm fork length (FL)). Spawning probably occurs offshore from February to August. It exhibits pair courtship in schools exceeding 1,000 fish, primarily during the full moon and waning moon periods between February and October (Graham and Castellanos 2005). In Cuba, there are two main peaks in reproduction: March-April and July-August. It can attain a maximum size in excess of 50 cm total length (TL) and is common to 40 cm FL (Smith-Vaniz 2002).
Systems:Marine

Use and Trade [top]

Use and Trade: This species is a component of artisanal fisheries and is also fairly sought after by anglers (Smith-Vaniz 2002). There is an increasing trend in catch landings for the Bar Jack, with zero catch reported from 1950-1998, a peak in landings at 34 tonnes in 2001 from Puerto Rico, followed by fluctuating catch landings reported from the U.S. and Puerto Rico. In U.S. waters, it is a small component of commercial carangid fisheries. There have been reported declines from Puerto Rico since the early 2000's. It is the most common jack harvested in Cuba (F. Pina-Amargos pers. comm. 2012) and is the main target of the Jack fishery; landings range from 300 to 560 tonnes between 1959 to 1997 (Claro et al. 2001). There are no reported catch landings for the Bar Jack in the eastern central Atlantic.

Threats [top]

Major Threat(s): There are no indications at present time of global population declines from harvesting, but there are records of landings declines in parts of its range. It is potentially vulnerable to regional overfishing due to net fisheries.

Conservation Actions [top]

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