Much of the interest in dynamics in the Bering Sea, now and in the past, has been spurred by concerns over the stability and sustainability of its vast living resources. Particularly prominent today are depressed popula-tions of several species of marine mammals, notably great whales, Steller sea lions, fur seals, harbor seals, and sea otters, and of additional species of considerable economic importance, such as king crabs, shrimp, and Pacific Ocean perch. The reason for the collapse of whales, shrimp, and Pacific Ocean perch is known—they were killed by commercial fisheries. The recent decline of sea otters in the Aleutian Islands is thought to have been caused by increased predation. The reasons for diminished popula-tions of other species are not known, or at least not agreed upon, and have been the stuff of extensive, often rancorous debate. No less dramatic, however, have been spectacular increases of certain fishes, such as flat-fishes, walleye pollock that grew in abundance by nearly an order of mag-nitude between the 1960s and 1980s, and Pacific salmon that provided
