Double-Crested Cormorants and Fisheries Management: Policy, Perceptions, and Research

Monday, August 20, 2012: 1:15 PM-3:00 PM
Ballroom E (RiverCentre)
Continued recovery of continental double-crested cormorant populations have lead to increased social conflict and the pursuit of remediation at local and broader scales.  Consequently, the subject provides a unique overlap between wildlife and fisheries disciplines and carries the potential for competing approaches when managing exclusively.  Concurrent research describing cormorant diets and their interactions with fisheries is expanding and management policy is under review.  The objective of this symposium is to provide agencies context when seeking a multi-discipline approach for the sustainable management of both avian and fisheries resources.  This symposium seeks to blend the technical aspects of cormorant-fisheries research with the social and policy components to provide all levels of professionals a better understanding of cormorant interactions with aquatic resources and their users, future research needs, and management policy.

While this symposium will focus on double-crested cormorant-fish interactions, presentations on other piscivorous birds, such as white pelicans, and their influence on fisheries resources are also welcome.
