Justification
This species has been exploited throughout its range, but little information is available to adequately quantify declines. More data is needed to determine the status of this species' population, especially as there are indications of reduced CPUE and body-size in the reported catches. It is listed as Data Deficient.

Description
In India, this species along with Holothuria scabra and Bohadschia marmorata have been collected over the last 1000 years. Fishermen began collecting other species in 1990, in response to high export value and population declines. Actinopyga echinites and Actionpyga miliaris populations were overexploited in some areas as early as 2 years later (Bruckner et al. 2003). In the Gulf of Manner and Pal Bay, India CPUE and size of specimens has dramatically declined (Bruckner et al. 2003).

Habitat and Ecology in detail

Habitat and Ecology
This burrowing species prefers soft bottom habitats. This species reproduces during the warm season and prefers to inhabit lagoons. In India, it is found on clean sands where it burrows (Conand 2008).
Classification scheme
Habitats Suitability Major importance

Threats

Use trade
It is fished in Sri Lanka and other islands of the Indian Ocean (Conand 2008). In India, this species has been considered one of the most valuable species for 1000 years (Bruckner 2006).

James and Badrudeen (1997) reported estimated annual landings of 460t of this species fresh along the southeast coast of India. However, the export of beche-de-mer has declined from 70t in 1996–1997 to 3.8t in 2001, primarily due to over-exploitation.

Threats in detail

Threats
This species has been overexploited by multispecies fisheries in some countries due to inadequate management (Asha and Muthiah 2007). 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.

Conservation Actions Information
This species has been cultured for purposes of stock restoration (Asha and Muthiah 2007).

Sea cucumber collection has been banned in the Andaman and Nicobar Islands (Bruckner et al. 2003). The Ministry of Environment, Government of India, has banned both the export and fishery of sea cucumbers from June 2001 onwards (Asha and Muthiah 2007).
