1.37 Fur seals on St. Paul Island. Every year, hundreds of thou- sands of northern fur seals return to their haul-outs in the Pribilof Islands in Alaska to breed, give birth, and teach their pups to swim, hunt, and survive in the Bering Sea. U.S. commercial fur sealing operations continued on St. Paul until 1984, but despite a reduction in harvest, the population of fur seals has continued to decline. Possible reasons include climate shifts in the North Pacific, chang- es in the availability of prey, and new or increased interac- tion with commercial fisheries that increase mortality. Here are data on the estimated number of fur seal pups born on St. Paul Island (in thousands) from 1979 to 2014, where a dash indicates a year in which no data were collected:28 FURSEALS Arco Images GmbH/Alamy
