Habitat and Ecology

This species inhabits shallow waters on sandy bottoms in Madagascar (Conand 2008).

No information is known on changes of habitat requirements during the life history of the species, but generally, the juveniles of aspidochirotids are cryptic and small individuals that may migrate into adult habitat later (Purcell 2004).

Threats

Major Threats

Although this species was recently described by Massin et al. (1999), it has been commercially exploited (Conand 2008) by fishermen who call it "Tigerfish", which is the same name as Bohadschia argus. In Tanzania, this species is possibly part of a multispecies fishery currently in decline (Conand 2008). In Seychelles, it presents a density of 1.62 ind*ha-1 and it is currently underexploited (Aumeeruddy and Conand 2008).

Although not one of the most important species (medium value) for fishery purposes, it can be expected that this species may become more popular after the depletion or reduction of other species of higher commercial importance and value

Many sea cucumbers are broadcast spawners, which can limit the fertilization success of a species in exploited populations.

Management

Conservation Actions

Conservation Actions
There are no known species specific conservation measures for this species, but its distribution directly overlaps with several marine protected areas. More research is needed on the status of this species' population

With the inclusion of Isostichopus fuscus in CITES Appendix III, a debate started whether the conservation of this group may be addressed with their inclusion in one of CITES appendices. The debate started in Conference of the Parties (CoP) 12 (Santiago, Chile) and extended to CoP 14 (The Hague, Netherlands). No recent advances have been achieved on this matter. For a revision of the possible pros and cons of a CITES listing, please see Toral-Granda (2007).
