• Authorities in the western US state of Oregon have euthanised four sea lions in the last month as part of a program to protect salmon runs and steelhead trout that are at risk of going extinct.
  • The killings were necessary to save migrating steelhead that have been ravaged by the sea lions in recent years as they swim upstream from the ocean to spawn.
  • Salmon were also threatened by the sea mammals, whose population has exploded since the Marine Mammal Protection Act was passed in 1972.
  • Two years ago, the sea lions destroyed 25 percent of that wild steelhead run.
  • They killed about 512 fish and that represented about one fourth of all the fish that we had left.He
  • State was authorized to kill up to 93 sea lions a year but he expected that no more than 40 would be removed this year.
  • Authorities in the past have used various non-lethal techniques, including loud noise or rubber buckshot, but the animals have adapted and learned how to avoid the threat.
