Catch rate of large Tanner crab (C. bairdi) in early trawl surveys (from Hayes and Reid 1975). well as intense competition among individual vessels of the now large fleet. The immense resource of C. opilio Tanner crab offers an opportunity if suffi- cient markets can be found. At present, however, C. opilio have a landed value of only $, compared to $ for C. bairdi. Moreover, king crab prices appear to be falling, perhaps in response to recent record catches and prices. It is evident that eastern Bering Sea crab fisheries are headed toward leaner times unless new markets are de- veloped on both domestic and international Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hood, D.
