. The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder. Oceanography Bering Figure 2. Eskimos walrus hunting in the Bering Sea (photograph courtesy of John J. Burns). only 27 years between discovery and extinction (Hunt 1975). At least part of the herring's ecological niche appears to have been replaced by the Alaskan pollock (Wespestad, Chapter 32, this volume); the sockeye salmon (Straty, Chapter 35, this volume), once endangered and still under heavy pressure, is being restored, but international cooperation will be necessary in order to avoid further, even acciden- tal, depletion of the stocks. Throughout recent history the wide diversity of the living resources of this region has been known, but only recently has it been fully appreciated (Favorite, Chapter 28, this volume). Large harvests of pollock, cod, ocean perch, black cod, halibut, rattails, tanner and king crab, and, more recently, shrimp are now being taken by many of the major fishery nations of the world. Until recently Japan harvested by far the most, followed by the ; but since the passage of the 1977 Fisheries Conservation Act the United States is catching up and now clearly dominates the crab fishery. The commercial catch of finfish is discussed by Bakkala (Chapter 61, Volume 2) and of crabs by Otto (Chapter 62, Volume 2). The potential for other fisheries is treated by McDonald et al. (bivalve mollusks. Chapter 67); Hughes (surf clams. Chapter 68) and Macintosh and Sowerton (gastropods, Chapter 69, Volume 2). The large annual tonnage constituting the human harvest of fish represents less than 4 percent of the nekton and benthos required to support the extremely large population of mammals and birds dependent upon this resource (Laevastu and Favorite (Chapter 37, this volume). xvii.
