Both my ponds have been stripped multiple times by river otters. Discouraging, to say the least.
John it is depressing. We have killed two adult otters in the last 6 weeks, however I fear how much damage they may have already done to the fish population. Plus what if they left juveniles behind. After dealing with the river otters a few years, I've gotten pretty good at just getting a gut feeling when "they're back". Saw a big water-turkey this morning getting a fish. Luckily they have not been much of a problem this year.
