Avoiding Otter Captures: The river otter population continues to increase through natural expansion of existing populations and reintroduction efforts. Trappers are urged to learn to identify otter sign and, where exist, to adopt the following recommendations to avoid the accidental capture of otters while trapping beavers: When using snares, set loops at 10 to 12 inches in diameter. Use baited sets for beavers where feasible. Avoid main channels in ponds and primary crossings where otter sign is present. Report accidental otter captures to your local wildlife conservation officer through your Pennsylvania Game Commission region office.
