Otters and people

  • Indigenous peoples did not kill otters; it was bad luck to do so because they were considered one of the most powerful characters in the animal world.
  • Otter pelts are extremely durable and commonly used for men’s coats. However, in Yukon less than 50 are trapped each winter.
  • Otters are great at fishing and not always a welcome guest at fish farmed lakes.
