I use staked lines. GBH's either walk the banks or wade in. They don't land in water unless they are sure it's shallow. If there is staked line in their way they can't get to the fish. I purchase furring strips from the local lumber yard and makes stakes out of them. Once I drive the stakes in at water's edge with a rubber mallet I screw in one inch dry wall screw 3 or 4 inches above the water line, another one up about 4 inches more and a third up a little farther.
I string cheap mono from Walmart in the 25 to 50 lb. test rang from screw to screw around the pond. Wrap the mono around each screw a few times and then loop it for it to hold.
It's not the eye sore you may think it is nor does it hinder pond use, and you only need a new stake when the bank turns. Two on a straight run at enough.
The idea is to have the lines low enough that the bird can not go under it but high enough it can't go over the top line.
