Habitat and Ecology

This species lives over rubble in sandy bottoms or among seagrass and around shallow reefs between 0 and 30m. It is distributed mainly in shallow coral reef areas, inner reef flats and outer slopes of the reef. It remains buried during the day (Conand 2008) whilst Muthiga et al. (2007) reports it to live in sandy patches between coral heads in reef lagoons in Kenya. In the Comoros, it can be found over sand and coral rubble between 5 and 30m. It buries during the day and comes out at night to feed (Samyn et al. 2006).

This species lives in the intertidal zone on inner flats of the barrier reef in the Toliara area (Madagascar). It is generally found on sandy areas located in between alive or dead coral heads. It has also been observed on the sea grass beds of the inner flat and on deeper sandy-muddy bottoms.

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

Population

Population

This species is common in the Africa and Indian Ocean region with abundant populations (Conand 2008). In Seychelles, it has been observed at population densities of 0.13 ind*ha-1, with an estimated stock of 486 tonnes in the Seychelles and it is considered unexploited (Aumeeruddy and Conand 2008). It is common in shallow reefs off the Kenyan cost (Muthiga et al. 2007). In Mayotte (Comoros), it is relatively abundant and it represents 13% of all holothurians present, with a mean density of 0.003 ind*m-2 (Pouget 2005).

This species is not abundant in Madagascar area. Sub-populations are, however, observed along the west coast (Toliara) from Anakao to Lamboara and in Nosy-be (Rasolofonirina pers. comm.).

Threats

Major Threats

The impact of fisheries on this species are not known.

Although not one of the most important species (low 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 conservation measures in place for this species. It is likely found in at least some protected areas within its range.

With the inclusion of I. fuscus in CITES Appendix III, a debate started about 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).
