Justification: Lutjanus decussatus has been assessed as Least Concern. This broadly distributed species is harvested as a food source, but this is a subsistence scale fishery, and there is no indication that stocks are being over-exploited. This species is not considered to be impacted by any major threatening processes at present. |
|
| Range Description: | Lutjanus decussatus is distributed from southeast India and Sri Lanka, to Papua New Guinea and Micronesia, and north to the Ryukyu Islands, Japan (FAO 2001). The distribution of this species is also reported to extend south to the Great Barrier Reef (Michael 2004). |

| Habitat and Ecology: | The snapper, Lutjanus decussatus, is found on coastal reef faces and sandy slopes with scattered patch reefs at a depth range of 2 - 30 m. This species is also less commonly found on offshore reefs. Fish are typically found to occur individually, but occasionally form schools. Food items include smaller fishes and crustaceans. This species can attain lengths of 35 cm, but lengths of around 20 cm are more common. |
| Systems: | Marine |
| Major Threat(s): |
Lutjanus decussatus is of minor commercial importance, due to its small size. It is caught by subsistence fishers using handlines, traps and gill nets. This species is mostly marketed fresh (FAO 2002). It is also taken for the aquarium trade, but in very low numbers. In Indonesia numbers have fallen over the last eight years, and fishing pressures, particularly fish fences, have increased (J. Curtis-Quick pers. comm. 2009). Due to the coastal nature of this species, it may also be impacted by coastal development and pollution. However, this is a localised threat, and not known across the species' entire range. |
| Conservation Actions: | There are no species-specific conservation measures in place for Lutjanus decussatus, however the distribution of this species may coincide with a number of designated marine protected areas. Further research on population, harvest levels, and threats is recommended; as well as monitoring of fisheries data and harvest for the aquarium trade to ensure the population is not suffering significant declines. |
