That year, Japan pulled out of the treaty, arguing, in part, that the seals had grown so numerous that they had begun to harm Japanese fisheries, but in 1957 the four original signatories ratified a new treaty. At that time, U.S. biologists successfully argued that cutting the number of female seals would decrease the age when the animals first became pregnant, contributing to an increase in pup numbers and survival. About 300,000 Pribilof females were killed between 1956 and 1968 on land, and another 16,000 were taken at sea for research between 1958 and 1974.
But the herd didn’t respond as expected, and the population began to slide. Even after the female take ceased, numbers kept trending down, and government biologists ended the commercial harvests on St. George in 1973 and began a long-term program to monitor the island. A ferocious public campaign against killing the seals, combined with shrinking markets for their fur and the lapse of the 1957 treaty, would end the commercial harvest altogether in the Pribilofs by 1984. Native residents have since been allowed to kill a small number of juvenile male seals for food.
Once the industrial harvest ended, funding for the study of these mammals plummeted. In 2004, the National Marine Mammal Lab-charged with conducting a census of the population and monitoring its status-had virtually no budget for fur seal research. “We call it the ‘Pribilof Islands Program,’ but it’s just me handling the management end and Rolf and his bunch from the lab doing the research,” says Dave Cormany, who administers the program from Anchorage with long visits to St. Paul.

那年, 日本拔出了条约, 争论, 一部分, 封印增长很众多他们开始危害日本渔场, 但在1957 四位原始的签字者批准了一个新条约。那时, 美国生物学家成功地争辩说, 削减女性封印的数量会减少年龄当动物第一次变得怀孕, 贡献对在小狗的增量编号和生存。大约300,000 位Pribilof 女性被杀害了在1956 年和1968 年之间在土地, 并且另外16,000 被采取了海上为研究在1958 年和1974 年之间。
但牧群依照被期望没有反应, 并且人口开始滑。在女性作为停止, 编号继续趋向下来以后, 1973 年和政府生物学家结束了商业收获在圣乔治和开始一个长期节目监测海岛。一次凶猛公开竞选反对杀害封印, 与收缩的市场为他们的毛皮和1957 的流逝年条约被结合, 一共会结束商业收获在Pribilofs 在1984 年以前。当地居民从那以后被允许杀害很小数量的juvenile 男性封印为食物。
一旦工业收获被结束, 资助为这些哺乳动物的研究笔直落下了。2004 年, 全国海洋哺乳动物实验室被充电与举办人口的人口调查和监测它状态有实际上没有预算为毛皮封印研究。"我们称它` Pribilof 海岛节目, ' 仅它是正义的我处理管理末端并且Rolf 和他的束从实验室做研究," Cormany 说戴维・, 执行节目从安克雷奇以长的参观对圣保罗。
