The Bering Sea, which lies between the United States and Russia, is one of the most productive ecosystems in the world and has prolific fishing grounds. Yet there have been significant unexplained population fluctuations in marine mammals and birds in the region. The book examines the Bering Sea ecosystem's dynamics and the relationship between man and the ecosystem, in order to identify potential reasons for the population fluctuations as well as identify ways the Sea's living resources can be better managed by government.

"Alaska pollock is everywhere. If you're eating fish but you don't know what kind it is, it's almost certainly pollock. Prized for its generic fish taste, pollock masquerades as crab meat in california rolls and seafood salads, and it feeds millions as fish sticks in school cafeterias and Filet-O-Fish sandwiches at McDonald's. That ubiquity has made pollock the most lucrative fish harvest in America--the fishery in the United States alone has an annual value of over one billion dollars. But even as the money rolls in, pollock is in trouble: in the last few years, the pollock population has declined by more than half, and some scientists are predicting the fishery's eventual collapse. Crucial to understanding the pollock fishery, he shows, is recognizing what aspects of its natural history make pollock so very desirable to fish, while at the same time making it resilient, yet highly vulnerable to overfishing. Bailey delves into the science, politics, and economics surrounding Alaska pollock in the Bering Sea, detailing the development of the fishery, the various political machinations that have led to its current management, and, perhaps most important, its impending demise. He approaches his subject from multiple angles, bringing in the perspectives of fishermen, politicians, environmentalists, and biologists, and drawing on revealing interviews with players who range from Greenpeace activists to fishing industry lawyers."--Amazon.

For an unknown reason, the Steller sea lion population in Alaska has declined by 80% over the past three decades. In 2001, the National Research Council began a study to assess the many hypotheses proposed to explain the sea lion decline including insufficient food due to fishing or the late 1970s climate/regime shift, a disease epidemic, pollution, illegal shooting, subsistence harvest, and predation by killer whales or sharks. The report's analysis indicates that the population decline cannot be explained only by a decreased availability of food; hence other factors, such as predation and illegal shooting, deserve further study. The report recommends a management strategy that could help determine the impact of fisheries on sea lion survival-establishing open and closed fishing areas around sea lion rookeries. This strategy would allow researchers to study sea lions in relatively controlled, contrasting environments. Experimental area closures will help fill some short-term data gaps, but long-term monitoring will be required to understand why sea lions are at a fraction of their former abundance.
