River otter rehabilitation programs treat injured, oiled, and orphaned otters, requiring specialized expertise in handling, nutrition, and behavioral preparation for successful release.
River otters admitted to rehabilitation centers face welfare challenges from the stress of captivity, handling procedures, and the physical consequences of the original injury or orphaning event. Rehabilitation that focuses on rapid stabilization, appropriate social housing with conspecifics where possible, and progressive fishing skills development produces better welfare outcomes and higher release survival. The welfare of rehabilitated otters depends on both the quality of rehabilitation and the post-release environment — released animals monitored through GPS tracking can receive intervention if they struggle post-release.
