TABLE 5. --Catch per unit of Gulf shrimp trawl effort by depth for 

 Pandalus jordani taken off the Washington Coast in 

 1956 and 1958 



taken included Pandalus borealis, P. jordani, 

 P. hypsinotus, P. platyceros, and Pandalopsis 

 dispar. Pandalus borealis was dominant. Com- 

 mercial concentrations of P. borealis were 

 noted in Idaho Inlet, Stephens Passage, Lynn 

 Canal, Keku Strait, and Glacier Bay. Fair 

 concentrations were also observed in Gilbert 

 Bay, Port Frederick, Icy Strait, Fish Bay, 

 Katlian Bay, and off Baker Island (fig. 3). 

 P. borealis was taken in depths ranging from 

 13 to 178 fathoms (table 6). Best catches 

 were made in 30 to 70 fathoms; however, 

 occasional good catches were also made as 

 deep as 110 fathoms. 



Although not commonly found in commer- 

 cial quantities, Pandolopsis dispar was also 

 taken throughout the Southeastern Alaska area. 

 Best catches were made in Idaho Inlet and 

 Port Snettisham. Fair concentrations were 

 found in Gilbert Bay, Stephens Passage, Gla- 

 cier Bay, Port Frederick, Affleck Canal, and 

 Lynn Canal. P. dispar was captured at depths 

 of 20 to 220 fathoms, with best catches being 

 made between 50 and 120 fathoms (table 7). 



Small quantities of Pandalus hypsinotus were 

 taken in many of the bays and inlets of South- 

 eastern Alaska. Highest catches occurred in 

 Idaho Inlet, Tenakee Inlet, Keku Strait, Gla- 

 cier Bay, Lynn Canal, and Saks Cove. As in 

 the more southern waters off Washington 

 and Oregon, this species was not found in 

 hauls made offshore. Catches of P. hypsinotus 

 were noted at depths ranging from 16 to 109 

 fathoms. P. platyceros als_o was taken only 

 in small quantities, with the highest catch 

 being made in Keku Strait. Both P. hypsinotus 

 and P. platyceros appeared to be more preva- 

 lent in rocky areas, and their abundance may 

 be much higher in areas unfishable by trawls. 

 Occasional specimens of P. jordani were caught 

 in Southeastern Alaska. 



Central Alaska 



From 1953 to 1959, five exploratory shrimp 

 cruises were made in the central Alaskan 

 area between Cape Spencer and western Kodlak 

 Island. Sampling was conducted at depths from 

 15 to 233 fathoms. Species of pandalid shrimps
