Note from the editor
This issue contains original contributions in various fields of sea cucumber biology and fishery. As in previous issues, they are arranged in three major sections: new information, correspondence and publications. The number and quality of your contributions show your interest and provide recent information that could be discussed in the next issue.
Articles on ‘Spawning observations’ provide helpful information on the reproductive biology of several species. We hope that the request for ‘fission and regeneration observations’ will provide interesting replies.
New fisheries in North-East Russia and Baja California are presented here. The disquieting problem of the fishery in the Galapagos (see last issue, Apr. 1994) is discussed.
Several aquacultural experiments on sea cucumbers are being carried out. The results from the work done at ICLARM, Solomon Islands and in Hawaii show that it is possible to induce spawning and rear larvae, but there are still difficulties in obtaining settlement and growth of juveniles.
However some publications, particularly those of the Central Marine Fisheries Research Institute of Cochin (India), indicate that one species at least, H. scabra, can be grown to the juvenile stage and offers good prospects.
