In SPC Trochus Information Bulletin #8, I raised the idea of broadening the scope of the bulletin into a multi-species molluscs bulletin to make it more attractive to our readers. After much discussion, it was decided that in order to maintain ‘brand recognition’ and retain the same ISSN number for libraries around the world that receive the SPC Trochus Information Bulletin, the name of the bulletin needs to be retained. However, to make it broader, more interesting to readers and more attractive to contributors, the bulletin has incorporated a sub-title "incorporating molluscs and other shellfish" to its established name. As of this bulletin, the SPC Trochus Bulletin will now be known as "SPC Trochus Information Bulletin, incorporating molluscs and other shellfish". I wish to take this opportunity to thank many people, especially Aymeric Desurmont, Garry Preston, Tim Adams, Jean-Paul Gaudechoux, Warwick Nash and Barney Smith for their contributions to this discussion.

The printed copy of this issue includes a special trochus manual, "Trochus hatchery and seeding techniques — A practical manual", published as an outcome of the ACIAR-funded trochus research in the Indo-Pacific region. All readers on the mailing list of the SPC Trochus Information Bulletin will also receive a copy of the trochus manual, and if there is a strong demand for it, SPC may consider publishing it again as a special publication of the SPC Trochus Information Bulletin.

Happy reading and I look forward to hearing and receiving some interesting contributions to the next bulletin from all of you.
