Great Blue Heron Problems

What can I do to keep a great blue heron away from my backyard pond that has Koi in it? Will any statues, mobiles or metal objects work? I just purchased 6 Koi last night and a heron was already scouting out the pond early this morning.

The only way to protect the fish from the great blue heron is to cover the pond with hardware cloth or netting. It is doubtful that the bird would be frightened away by fake owls, snakes or scarecrows. Great blue herons, like all other native species, are protected by state and federal laws.
