This issue of SPC Beche-de-mer Information Bulletin contains eight articles and communications from several countries. It also includes abstracts about sea cucumbers that were presented at the 14th International Echinoderm Conference that was held in Brussels in August.

The first article comes from Tonga. Poasi Ngaluafe and Jessica Lee analyse the change in weight of ten common commercial sea cucumbers. They discuss the possible reasons for the discrepancy they observe between their results and previous ones, and the implications for fisheries management in Tonga.

We are also very pleased to present some insights about sea cucumbers and sea cucumber fisheries in the Colombian Caribbean. The article is from the team of Adriana Rodríguez Forero. They report on species that could be new for the Caribbean and conclude with stressing the importance of initiating a management plan for the Colombian fishery resource.

Some news also from Madagascar, where Antoine Rougier et al. talk about the strategies for improving survivorship of hatchery-reared juvenile Holothuria scabra in community-managed sea cucumber farms. Their findings indicate that technical solutions must be coupled with active management to maximise the survivorship of juveniles.

From the shallow lagoons of western and southern Mauritius, Katrin Lampe presents statistics on a total of 3411 holothurians, comparing their diversity and population densities in 16 survey sites that had been exploited to different degrees.

Ajith Kumara et al. worked on the breeding and larval rearing of three tropical sea cucumber species, Holothuria scabra, Pseudocolochirus violaceus and Colochirus quadrangularis, in Sri Lanka. They were successful in obtaining juveniles for the three species.

Karim Mezali and Dina Lila Soualili analysed the ability of holothurians to select sediment particles and organic matter. For that, observations on the digestive contents of holothurians from shallow waters in Algeria are presented. The results illustrate the diet specificity of the species.

Mercedes González-Wangüemert et al. assessed the Holothuria arguinensis populations inside Ria Formosa (South Portugal) through a volunteer programme. They found high densities but the values oscillated, depending on transects and habitats.

Kalo Pakoa and Ian Bertram summarise the current state of sea cucumber fishery management in 12 Pacific Island countries or territories and the various actions that are taken to establish formal fishery management frameworks.

Finally, we publish several short reports about underwater observations of spawning events of juveniles: from Rodrigue by Alexandre Bédier et al., who also synthesises data recorded in previous bulletins; from Papua New Guinea by Jeff Kinch et al.; and from India by Hithesh Kardani and Mayurdan Gadhavi.

We received many communications, among which was a description of the workshop (SCEAM Indian Ocean) that was held in Zanzibar in November 2012. We would also like to congratulate Thomas Plotieau, who recently had his PhD thesis on H. scabra’s diet accepted. He specialised in the bacteria assimilated from the sediment eaten by this species.
