Habitat
Habitat details as listed in assessment
This species inhabits offshore coral reefs and trawling grounds. It is frequently encountered in large schools with other Lutjanus species (Lieske and Myers 1994), and feeds on fishes and crustaceans (Sommer et al. 1996). Its maximum size is about 30 cm, but more commonly to 20 cm and maturity is reached at 12 cm (Anderson and Allen 2001). The age at maturity is 1.1 years and the reproductive lifespan is estimated at 4.5 years (Martinez-Andrade 2003). The estimated maximum age is at least 11 years (Anderson and Allen 2001). When applying an age at first reproduction of 1.5 years and longevity of 11 years, its estimated generation length is 6.25 years based on the following equation recommended by the IUCN Red List methods: Age at first reproduction + (Age at last reproduction -“ age at first reproduction)/2.
Threats and conservation measures listed
Threats listed in assessment
Fishing activity is not known to be driving declines in the UAE at this time. Corals in the UAE and Arabian Gulf have severely declined due to the increasing frequency of mass bleaching events caused by rising water temperatures, which is a consequence of climate change, as well as pervasive coastal development (Riegl et al. 2018, Burt et al. 2019).
