Elasmobranchs are interesting both from a scientific perspective and because of the characteristics their biology poses for their management. They may be associated with other major fisheries and often fail to get the attention they deserve. This publication is a contribution to reducing the oversight that is so often the misfortune of this group. We hope that the overview and detailed regional descriptions will help both the worker at the regional level as well as those involved in overall syntheses.
