Sea otter conservation began in the early 20th century, when the sea otter was nearly extinct due to large-scale commercial hunting. The sea otter was once abundant in a wide arc across the North Pacific ocean, from northern Japan to Alaska to Mexico. By 1911, hunting for the animal's luxurious fur had reduced the sea otter population to fewer than 2000 individuals in the most remote and inaccessible parts of its range. The IUCN lists the sea otter as an endangered species. Threats to sea otters include oil spills, and a major spill can rapidly kill thousands of the animals.

  • 해달보호활동(海獺保護活動; sea otter conservation)은 20세기 초에 시작되었다. 당시 해달은 대규모의 상업적 수렵으로 인해 멸종위기에 처해 있었다. 일찍이 해달은 북태평양 일대, 즉 일본 북부, 알래스카, 멕시코에 걸쳐 널리 분포하고 있었다. 하지만 1911년까지 모피를 노린 수렵으로 인하여 해달의 개체수는 인간의 손이 닿지 않는 변두리 구석을 중심으로 2000 마리까지 격감했다. 그 뒤 20세기에는 러시아 극동부, 서알래스카, 캘리포니아의 생존 개체로부터 해달의 개체수가 증가하였다. 1960년대부터는 과거 해달이 서식한 지역으로 인공적 이동도 진행되어 북아메리카 서해안에 걸쳐 넓게 분포시키는 데 성공했다. 그 이외 지역에서도 재도입이 성공한 곳이 있어, 해달보호활동은 중 가장 성공한 사례 중 하나로 꼽히고 있다.

  • ラッコの保護活動は、20世紀初頭に始まった。当時、ラッコは大規模な商業狩猟により、絶滅の危機にあった。かつてラッコは北太平洋、すなわち北日本、アラスカ、メキシコに亘って広く分布していた。1911年までの毛皮目的の狩猟により、ラッコの個体数は人間の手が届かない辺境を中心とした2000頭にまで激減した。 その後20世紀の間に、ラッコの個体数はロシア極東部、西アラスカ、カリフォルニアの生き残りから増加した。1960年代からは、かつてラッコが生息した地域への人工的移動も進められ、北アメリカ西海岸に広く分布させることに成功した。その他にも若干だが成功した地域もあり、ラッコ保護活動は、海洋生物の保護活動 (Marine conservation) として最も成功した事業の1つと考えられている。 (ja)
