Defining Economic Impacts and Developing Strategies for Reducing Avian Predation in Aquaculture Systems


PROJECT GOAL: Develop an understanding of the economic impacts of damage inflicted on aquaculture production systems by cormorants, pelicans, wading birds, and waterfowl and develop tools and techniques for reducing that damage.  

Objective 1: Determine the economic impact of cormorants, pelicans, and wading birds on different productions systems used in the catfish, baitfish, and crawfish industries.

Objective 2: Develop and evaluate tools and strategies for dispersing fish-eating birds from off-site roosts, loafing areas and aquaculture facilities.

Objective 3: Determine the role of American white pelicans in the epidemiology of Bolphorus trematodes at catfish facilities.

Objective 4: Develop methods for monitoring double-crested cormorant distribution and population growth.

Objective 5: Develop methods for managing breeding colonies of double-crested cormorant impacts to yellow perch fisheries in the Les Cheneaux Islands area of Michigan.
