other exploratory fishing activities P. borealis 

 has been captured as far south as Puget 

 Sound, Wash. 



Thus P. jordani, the dominant species in 

 southern waters, is replaced as the dominant 

 species by P. borealis in northern waters, 

 with the transition occurring off British Co- 

 lumbia, 



P. hypsinotus was found in all portions of 

 the region surveyed, and P. platyceros was 

 captured in all portions surveyed south and 

 east of Cook Inlet. Members of these species 

 are a minor portion of the total catch taken 

 in trawls, but traps and pots, which were set 

 in rocky areas, caught fair quantities of both. 



Pandalopsis dispar was taken from Manhat- 

 tan Beach, Oreg., to the Alaska Peninsula 

 in depths of 20 to 233 fathoms. As with 

 P. borealis this species was also found to be 

 most abundant in the central Alaskan and 

 Alaska Peninsula areas (fig, 8). P. dispar was 



generally taken in somewhat deeper than 

 P. borealis (figs. 9-12), 



P. jordani, P. borealis, and Pandalopsis dispar 

 appear to occur in concentrations adequate 

 to support large-scale commercial operations. 

 Pandalus platyceros, which grows to a size 

 comparable with the size of Gulf of Mexico 

 penaeid shrimps, may be available in sufficient 

 quantities over rocky, rough bottoms to war- 

 rant small-scale pot fisheries, P. jordani is 

 already extensively fished off the California, 

 Oregon, and Washington coasts, while P. bor- 

 ealisis harvested in the waters of Southeastern 

 and central Alaska, The results of Bureau 

 explorations suggest that P. borealis and Pan- 

 dalopsis dispar may reach maximum abundance 

 levels in waters adjacent to the Alaska Penin- 

 sula, along the Aleutian Islands, and in the 

 Bering Sea. The commercial potential of these 

 species may be many times greater than is 

 now realized. Distance from markets and 

 other economic factors obviously will affect 

 utilization of the species.
