Management and Ecology of River Fisheries

The interactions between wild bird populations (many protected by law) and fish, particularly those under commercial culture or part of a fishery is subject of much controversy. Ecological, environmental and conservation pressures run alongside commercial pressures on exploited fish populations. This exciting book draws together contributions from all over the world to provide a fascinating insight into many case studies and conflicts in managed situations as well as looking at the overall ecology of such interactions in normal un-managed ecosystems.
