Editorial

It is a great pleasure to present the 20th issue of the SPC Beche-de-Mer Information Bulletin.

In recent months, several important CITES (Convention on the International Trade in Endangered Species) activities related to sea cucumber management have occurred. Following the CITES Technical Workshop in Malaysia, in March 2004, the CITES Animals Committee met in South Africa, in April 2004, and adopted several recommendations. The 13th meeting of the Conference of the Parties will be held in Thailand, in October 2004. Further details can be found in this issue.

During the workshop on Advances in Sea Cucumber Aquaculture and Management (ASCAM) organised by the Fisheries Department of the Food and Agriculture Organization (FAO), recommendations were formulated and will be used in future collaborations. The proceedings of the ASCAM workshop are published by FAO (see the Abstracts and publications section).

Given the relative scarcity of direct observations of holothurian juveniles in the wild, Glenn Shiell submitted a questionnaire in issue 19 of this bulletin. He summarises here the information collected so far, and hopes that responses will continue to arrive, helping us to better understand this critical life stage.

Culturing several marine species in the same pond at the same time (an activity referred to as “co-culturing”) could be an important development path for sea cucumber aquaculture. Rayner Pitt describes his experiences in Vietnam with sandfish (Holothuria scabra) and shrimp (Penaeus monodon).

The consequences of fission on population densities and biomasses of Holothuria atra have been further studied on Reunion Island by Chantal Conand.

Pradina Purvati  has studied fissiparity in Holothuria leucospilota from tropical northern Australian waters.

For his Bachelor's degree in agribusiness (aquaculture), Tim Lo studied the valuation of sea cucumber attributes through laddering. His findings are presented in this issue.

We continue to publish data on sea cucumber spawning observations in the wild, following the questionnaire we submitted in 1992 to the bulletin's readers (see issue #4 of this bulletin).
