3 PREFACE Symposium Organizers: Gamperl, A. Kurt Dept. of Organismal Biology, Portland State University Anthony P. Farrell Dept of Biol.Sciences, Simon Fraser University Don MacKinlay Fisheries Canada CONGRESS ACKNOWLEDGEMENTS This Symposium is part of the International Congress on the Biology of Fishes, whose main sponsors were Fisheries and Oceans Canada (DFO), the University of Aberdeen, Scotland and the US Department of Agriculture. The main organizers of the Congress, on behalf of the Physiology Section of the American Fisheries Society, were Don MacKinlay of DFO (overall chair, program and proceedings), Jan Flint (registration and accommodations) and Dominic Houlihan, University of Aberdeen (local arrangements). Preparation of the Proceedings was accomplished with the editorial and word-processing assistance from Cammi MacKinlay and Karin Howard. I would like to extend a sincere thank you to the many contributors who took the time to prepare a written submission for these proceedings. Your efforts are very much appreciated.
