Otters are friendly, semi-aquatic animals that feed heavily on fish, shellfish, and sometimes even waterfowl. Although otters are not known to bother humans directly, their fish hunting activities can be problematic to water areas that humans frolic and the surrounding infrastructures, making otter control and removal necessary. Their hunting activities on water and land can result in significant financial losses for fish farms and other businesses and should be handled quickly, safely, and effectively.
