Coexisting with Aquatic Wildlife
As human activity intersects with aquatic ecosystems, conflicts can arise. Whether you live near a waterway, farm adjacent to streams, or recreate on lakes and rivers, understanding wildlife behavior helps prevent problems and protect both people and animals.
Common Wildlife Encounters
Beavers
Beaver dams can cause flooding on private property but also create valuable wetland habitat. Non-lethal management options include flow devices, tree wrapping, and habitat modification.
River Otters
Otters may feed on stocked fish in ponds and hatcheries. Fencing and exclusion devices are effective deterrents. Otters are protected in most states.
Herons & Cormorants
Fish-eating birds can impact small ponds and aquaculture operations. Netting, visual deterrents, and habitat management reduce predation without harming protected species.
Bears Near Streams
During salmon runs, bears concentrate along rivers. Store food properly, make noise on trails, and give bears space. Never approach a bear feeding on fish.
What to Do
Report Injured or Sick Wildlife
If you find injured, sick, or dead fish or wildlife, contact your regional FCRG office or call our hotline. Your reports help us monitor disease outbreaks and environmental hazards.
Invasive Species
Never release aquarium fish, bait, or aquatic plants into waterways. Clean, drain, and dry boats and equipment when moving between water bodies. Report invasive species sightings to FCRG.
Habitat on Your Property
Landowners with streams, ponds, or wetlands can take steps to improve habitat. FCRG offers free technical assistance for riparian plantings, erosion control, and fish-friendly land management.
