Dactylanthias aplodactylus has been assessed as Data Deficient. It is only known from a single specimen found around Ambon Island. Further studies on the deep water reefs around Ambon are needed to determine if it is in fact common in deeper waters. If this is the case, it would likely escape the potential threat of blast fishing, that occurs within its range.

Habitat and Ecology [top]

Habitat and Ecology:Dactylanthias aplodactylus is a demersal species. The Serranidae family are usually found on coral reefs or rocky substrata and the majority of species occur on continental shelves in depths less than 200 m. Except for occasional spawning aggregations, most groupers are solitary fishes and are generally resident on a particular reef for a long time (FAO 1999).

Like other species within the subfamily Anthiinae, this species may in fact be a deep reef (greater than 50 m) species and quite common. The shallow waters within this area have been relatively well surveyed (G.R. Allen pers. comm. 2009).

Threats [top]

Major Threat(s): It is unknown whether Dactylanthias aplodactylus is being impacted by any major threat processes. Surveys have found the waters around Ambon Island to be severely contaminated by domestic waste, a stress which has indirectly caused an increased parasite load on some reef fish (Evans et al. 1995). The coral reefs around Ambon and other Indonesian islands are also under threat from 'blast fishing' (Harger 1995). Dive teams have reported significant cracks in the coral reef around Ambon as a result of near constant blast fishing. If this is in fact a deep reef species, then it is unlikely to be impacted by blast fishing activity.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for Dactylanthias aplodactylus.

Further studies in deeper water around Ambon Island are needed to determine if this species occupies a deep water habitat.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
