@John - There's no "maybe" about the otter, I saw it there. It was in there for a couple of weeks and I know it took some fish. I saw the scales in its excrement...as I said, I walk the pond daily.
I know an Otter can really damage a pond. But it's a one-acre pond and was well stocked. I still see lots of small fish and don't think it could have wiped out the BG population in the two weeks before I ran it off. But...
