Preface

Recent studies on food quality for zooplankton have developed two new hypotheses, the importance of the dietary carbon to phosphorus (C : P) ratio and of certain ‘essential’ fatty acids. These new hypotheses, the controversies they have provoked and the general lack of field studies prompted us to organize a workshop. Thus, the first international Plankton Ecology Group (PEG) workshop on The Role of Food Quality for Zooplankton was held from 17 to 21 March 1996 at the Centre of Limnology in Nieuwersluis, the Netherlands. The main objectives were to take stock of the state‐of‐the‐art in food quality research, to address the factors that determine food quality, and to integrate the available information into a coherent and consistent view of food quality for the zooplankton. In contrast to most PEG meetings, we restricted the meeting to about 35 participants. However, international participation was broader than usual and included colleagues from North America and Asia, as well as Europe. The workshop’s organizers, Ramesh Gulati, a senior scientist, and Paul M. M. Weers, a post‐doc at the Centre Of Limnology, approached potential speakers, in some cases suggesting topics for presenta
