Editorial

Greetings. First of all we would like to apologize to our readers, colleagues and contributors for the long time it took to release this new issue of the Trochus Information Bulletin. Unfortunately, contributions were somewhat slow to come  and we had to wait this long to gather a suitable amount of material for publication. But we are proud to finally bring to your attention a suite of quality articles as well as the usual compilation of recently published papers.

This issue starts off with a contribution by Kalo Pakoa, Kim Friedman and Hervé Damlamian on the status of the trochus resource in Tonga, which provides a very comprehensive overview and a series of recommendations for management. Then comes a complete report on the population structure and abundance of Trochus niloticus in the Tubbataha Reefs Natural Park (Philippines), which addresses the insidious effects of poaching.This contribution is signed by Roger G. Dolorosa , Angelique M. Songco, Victor Calderon, Roy Magbanua and Jaysee A. Matillano. Finally, Ferral Lasi presents long-term data on trochus production in Solomon Islands (1953-2006), including regional comparisons and outlining interventions needed to cope with a significant decline in catches over the last decade.

We sincerely thank all our contributors for taking the time to share their knowledge and expertise. Perhaps we need to emphasize again that this Bulletin is yours to mould and that it welcomes contributions on all varieties of marine molluscs including bivalves and gastropods. We love trochus and will always encourage contributions on this topic, but don’t be afraid to send in your reports and observations on giant clams, green snails, cowries, conches, mussels, scallops, etc. If you are studying nudibranchs or cephalopods, don’t be shy, we will gladly publish your work as well. This bulletin is a unique outlet for all sorts of findings, questions and concerns. Aquaculture and fisheries projects as well as conservation and biology oriented subjects are equally well received. For instance, we would love to get notes and/or pictures of unique behaviours or interactions such as mating, spawning, egg laying, symbiotic associations, competition or predation (to name a few) to add to a special section of the Bulletin. Just provide the location, time of the day, any information on the available environmental factors that prevailed and your account of the activity. Short and sweet!

For those of you who might be wondering, we accept manuscripts in French and in English. If need be, we will help you polish your contribution. If you are not sure about a prospective topic, please send us a quick email to discuss your idea. Start digging for unpublished data or forgotten observations and give them a new life by publishing them in this Bulletin. You never know who might benefit from or be inspired by your contribution. It would be our pleasure to bring together a diversified and colourful issue #16… but we need your help. So spread the word!

We remind you that the SPC Trochus Information Bulletin is distributed worldwide and indexed in databases such as Aquatic Sciences and Fisheries Abstracts (ASFA). It is also available on the internet through the SPC web pages, where you will also find our complete instructions for authors (http://www.spc.int/coastfish/News/SIG-instructions.pdf).

We sincerely hope that you will enjoy this issue and we send you our warmest salutations from the faraway island of Newfoundland..

Jean-François Hamel and Annie Mercier
