Need advice on keeping loons, cormorants, gulls and herons out of a fish pond

[GillieSuit]

Howdy folks,

A good friend of mine has a small spring fed dugout with trout in it. The pond is very clear and due to the late spring melt this year is one of the few places with open water. As a result he has 4 loons camped out on his pond at the moment. They are eating his fish by the hundreds and he wondered what might work to get them off the pond and keep them out. At the moment they are just growing fish for fun, but might do some recreational fishing at some point. So covering the pond with netting of some kind may not be the best option.


Just wondering about options for managing avian predators on outdoor ponds.


Thanks,

Gillie.
