A useful tool for understanding the broad-ranging effects of changing environmental conditions in aquatic ecosystems, Theory and Application in Fish Feeding Ecology links theoretical and practical aspects of fish foraging research. Fish feeding experts share their recent research, filling the gaps between contemporary information and theoretical issues. The twenty essays in this volume examine foraging theory, habitat gradients and landscape ecology, disturbance, and invasive species. Theory and Application in Fish Feeding Ecology integrates recently uncovered information with current techniques to address the many problems involved in the management of fishery resources.
