Open Competition: Assessment of effectiveness of management measures to control damage by fish-eating birds .... - VC0107

This study will aim to evaluate management methods for controlling fish-eating bird (cormorant, goosander and red breasted merganser) activity on inland fisheries in England and Wales, in order to identify any effective methods that have minimal environmental impact and which reduce the need for licensed shooting. A literature review will be conducted to gain information on existing bird control practices and effectiveness of these practices. Sensory stimuli which trigger aversion behaviour in fish-eating birds will then be investigated by conducting a series of laboratory experiments to identify such stimuli (including sounds of varying frequency, light of varying wavelength and intensity, physical vibrations and taste aversion substances). The effectiveness of these stimuli under field conditions will be studied at river and stillwater fishery locations; field experiments will also be conducted to determine surface and underwater habitat management methods which are effective at discouraging fish-eating birds while minimizing impacts on other birds and the overall ecosystem. Project findings will allow recommendations to be made to MAFF regarding management practices for controlling damage by fish-eating birds,and the production of advisory literature for MAFF to distribute to interested parties.
