Editorial
It is a great pleasure to
present the 22nd issue of the SPC Beche-de-
Mer Information Bulletin, which is particularly rich and diverse.
I draw your attention to the new database of all articles and
abstract
published in the Bulletin to date. This was recently put togethe
by SPC’s Fisheries Information Section, and is available on
SPC’s website at: http://www.spc.int/coastfish/news/search_bdm.asp. The database includes close to 560 article and abstract
titles that can be searched by title, author’s name(s), scientific
name, region or country. Each search result is presented with a
hyperlink that allows downloading in pdf format. Your comments
and suggestions on how to improve this useful tool are
most welcome.
This issue of the Bulletin includes articles focusing on many
different
areas; in some cases, this is the first time research from
these locales has appeared in the Bulletin (e.g. the Comoros,
featured
in the article by Samyn et al.; Mauritius, addressed by
Laxminarayana; and Sri Lanka, addressed by Terney). These articles highlight the current interest in sea cucumbers in
the western Indian Ocean. Contributions about Madagascar by
Rasolofonirina and Jangoux and Mayotte by Conand et al. also serve to illustrate the progress in sea cucumber
research
in this region.
Identification of sea cucumber species is difficult. With CITES’
conservation concerns, the issue of identifying processed specimens
has become critical. One identification method involves
special preparation of the body wall to examine the calcareous
spicules. This method has been used in the Galapagos for
Isostichopus fuscus (see article by Toral).
Purcell presents advances from the important WorldFish Center,
which is developing technologies for sandfish restocking.
We continue to publish articles
on asexual reproduction by fissiparity.
Purwati presents her recent findings with Holothuria atra
and H. leucospilota and Kohtsuka et al. write about their
observation
of a Stichopus horrens specimen undergoing fission.
For this issue, we have not received answers to the different
questionnaires
presented in previous issues of the Bulletin, but we hope
to receive your contributions for the next issue on the following
important fishery-related subjects: overexploitation, sexual
reproduction,
recruitment and juvenile observations in the wild.
Proceedings of the 11th International Echinoderm Conference are
now published as: Proceedings of the 11th International
Echinoderm Conference, Munich, Germany, October 6–10, 2003:
Heinzeller, T. and Nebelsick, J.H. (eds), Taylor and Francis
Group, London, 633 p. You can order this publication through Taylor
and Francis website (http://www.tandf.co.uk/books/,
click on “Catalogue” in the menu on the left side and enter
Echinoderms Munchen in the search box). Several abstracts of published papers are
included in the Abstracts and New Publications section of this Bulletin.
The location of the 2006 International Echinoderm Conference
has not yet been decided. We hope to be able to give this
information
in the next issue of the Bulletin.
All previous issues of the Bulletin are available from SPC’s website
at: http://www.spc.org.nc/coastfish/news/bdm/bdm.htm (English and French
versions)
The latest issue of the “Echinoderm Newsletter” is available at:
