Apply innovative engineering design approaches to develop new or modify existing methods and technologies to control depredation. Reduce depredation by avian predators at aquaculture facilities by identifying habitat variables that can be manipulated. Evaluate best management practices to reduce risk of predation at aquaculture facilities from migrating and nonmigrating double-crested cormorants. Assess and validate fish-eating bird numbers and trends by aerial survey, use of satellite-and radio-transmitters, and double-observer counts. Quantify spatial and temporal effects on bird us patterns within and surrounding aquaculture areas under regulatory management of lethal and nonlethal roost dispersal. Identify spatial and temporal differences between nonmigratory and migratory cormorant populations to enhance management efforts within aquaculture areas.
