McRae ...................................................... 331 ————————————— vii Foreword The representation of exceptional scientists, broad range of papers, and quality of research present- ed at this symposium are truly remarkable, and they underscore the progress made since the 1980s, when publication of anything related to Hawaiian streams was difficult because interest at all levels was minimal, and only a few pioneering researchers were willing to commit time to the subject. The establishment of the Water Code in Hawai‘i and the formation of the Commission on Water Resource Management under the Department of Land and Natural Resources encouraged the Division of Aquatic Resources (DAR), which is assigned responsibility by Statute for the manage- ment and protection of all living aquatic resources in Hawai‘i, to focus on expanding the informa- tion base to assist in regulatory decision-making and lend credence to the development of instream flow standards. Fortunately, an existing collaboration between Dr. Robert Nishimoto (DAR) and Dr. J. Michael Fitzsimons (Louisiana State University) provided the seed to develop the program. The resultant 1990 Symposium on Freshwater Stream Biology and Fisheries Management, entitled New Directions in Research, Management, and Conservation of Hawaiian Freshwater Stream Ecosystems, represented the first effort to organize existing state-of-the-art knowledge and bring varied interests together. It led to development of a longer range plan which with the current symposium has effectively been accomplished with reference to its principal objectives. The mark of good science, however, is that the advance of knowledge inevitably leads to more questions. The discussions during this symposium have posed an important set of new questions. Application of the advancing knowledge to management has been lagging for institutional rea- sons more related to organization and influencing decision-makers than to the quality of the science involved, but that is no excuse for stepping back from new investigations to advance the science. In fact, as the institutional deficits are reduced, the demand for good science will increase rapidly. Effective steps to move the management component ahead have in fact been recommended in this symposium. We are nevertheless at a crossroad. If there is not regulatory commitment to rational manage- ment, there is danger that this symposium will become an end point
