Will a 4 ft fence around the edge of my pond stop blue heron from killing my trout ? I was told that they need to land on the land and not in the water. I need to know before I do the work. Sick of them fishing out my trout out of my 1/3 acre pond.
Driveway markers with a mesh of your choice works for me. I set them at a 40-45 degree angle in the water at the closest bed to the bank, and then put the marker ends out into the pond a smidge. Herons still hit the pond, but rarely do I see footprints adjacent to the beds.
It's worked extremely well in my hatchery pond where the CNBG tend to spawn in the same location. The depth may change, but the location stays the same.
