Translocate birds away from fish farms
A study cited in Mott 1978, effectively reduced a population of green herons Butorides virescens feeding at a fish hatchery in USA, by catching and releasing them 40 km away. No details are given regards the time period over which the reduced population level was maintained or the effort needed to catch the birds. The effects on fish farm productivity were not measured.
