As mentioned in the preface to Volume 22, however, a rearrangement following the Council's new committee system has been under consideration for some time. In October 1967, the Council passed the following resolution concerning the Annales biologiques: "Area chairmen's summaries should in the future not be included, but experts - not necessarily chairmen - should be invited to write summaries on herring and cod." In accordance with this, there are no area chairmen's summaries in the present volume. A summary on demersal fish in the distant northern seas, which had already been written by professor G. V. NrKOLSKY, has been incorporated in the comments on the following pages, and is hereby gratefully acknowledged. As in later years, professor G. HEMPEL has written a summary of the contributions to the herring chapter. He could take into consideration some contributions presented to the Statutory Meeting of the Council in October 1967, which could not be included in the present volume. They will eventually be printed in Volume 24. It is regretted that it has not been possible this year to include a summary on cod. By joined efforts of all concerned, it has been possible to speed up the production of this volume quite considerably, and possibilities are now available for a further shortening of the production time for the next volume. This has inevitably caused some inconvenience for contributors, staff and printers, but it is believed that the result justifies the effort, and the editor wishes to thank all concerned. A nnales biologiques and Statistical News Letters are to some extent complementary, and wherever possible, references have been inserted in the text of the present volume. Because of the earlier appearance of this volume, however, this has not always been possible, and general reference is therefore given to the following numbers of Statistical News Letters (issued, in print, or under preparation), where basic and detailed statistical data relevant to the information presented in this volume will be found: No.
