G blue herons, Canadian Geese, Green Herons, Osprey, Mergansers, Mink. Most eat our fish, one craps all over the place. They all qualify as nuisances...if I decide they are. I'm fortunate in that I am not as concerned about the pond contents as much as I am concerned about the entire package, above and below the water. Finding the correct balance of control and the effective ways to implement balanced control are the most I could ever hope for. In the meantime, if I don't like what M Nature has sent to my pond to party, I should probably stay home.
Now, having said all this, I still fear the appearance of an otter or beaver, and know that someday I will have to deal with it. In the meantime, tho, I try not to sweat the smaller stuff.
The operative word here is "try" not to sweat the smaller stuff...
