I have all sorts of fowl this year. Ducks, Canada Geese, Bald Eagles, Great Blue Heron, Water Turkeys and Pelicans. Its a wonder I have any fish left at all.
Tbar I've got an Overton's electro survey next month to see how bad the damage is...but it may be hard to determine otter vs bird damage.
If it's as bad as I think it might be...i may actually look into netting some or most of the 4 acre pond next year:
Maybe this could be useful for cormorant season, then could be taken down. Also, I wonder how easy this would be to set up & take down when you want to fish a netted area?
