Membership of the S.I.G. on Beche-de-mer has increased since the last issue, reflecting the interest and expansion of the group in and outside the South Pacific region. Thanks are due to the members who have contributed articles, letters or various information in the diverse range of disciplines dealing with sea cucumbers.
The reproductive biology of holothurians remains an important focus of scientific research, necessary for fishery management or aquaculture experiments. Spawning observed in the field is poorly documented and a request for information on spawning is included in this issue, with the hope to put together and then circulate the information.
In the last issue, the first part of the summary of a Japanese handbook on Stichopus japonicus described the biology and the rearing of larvae and juveniles. It is continued in this issue with data on the fishery and its management, and on earlier Japanese regeneration experiments on this species.
Attempts to tag holothurians have used various tags which are retained for more or less time according to the species tegument and tag used. Results of an internal micro-tag experiment started in Papua New Guinea seem promising.
The beche-de-mer fishery industry in Fiji shows boom-bust cycles which raise resource problems described here. Options for management and for dealing with socio-economic problems are presented. Opinions and comments from other experiences will be welcome.
