I'm experiencing a river otter problem in my ponds. I saw one under a floating dock and another in open water about two weeks ago. The otters didn't resurface and I haven't seen them since - just the evidence of their presence, half eaten fish. The previous otter occurrence was several years ago and the otter was constantly surfacing and submerging. I know that these creatures move around a lot and I've found partially eaten fish in several ponds. A professional trapper was out last week , but could not sight any of the creatures. He even returned in the evening with night vision binoculars and still nothing. However, he told me that most of his experience has been with beavers,feral hogs, and coyotes, but he plans to set traps this week.
The most disturbing concern is the stealth behavior these beasts. Maybe, they could have been around (off and on) for weeks or even months. Has anyone experienced similar otter behavior and how was it dealt with ? Any enlightenment would be appreciated.
