Four pandalid shrimps (Pandolus jordani, P. 

 platyceros, P. hypsinotus, and Pandalopsis dispar) 

 were caught, with Pandalus jordani being domi- 

 nant. Along the Oregon coast, highest abun- 

 dance* of P. jordani, was found off Tillamook 

 Head, between Cape Meares and Cape Lookout, 

 between Manhattan Beach and Cape Foul- 

 weather, and from Heceta Head to theCoquille 

 River (fig. 1). P. jordani was taken at depths 

 ranging from 50 to 250 fathoms with major 

 concentrations occurring between 70 and 109 

 fathoms (table 4). The availability of shrimp 

 at the extremes of this depth range dropped 

 off rapidly. 



Off the Washington coast, Pandalus jordani 

 was caught in commercial concentrations from 

 near Copalis Head, Grays Harbor to Willapa 

 Bay, between Destruction Island and Lapush, 

 and off Cape Flattery. Off Cape Beale, Van- 

 couver Island, B.C. (fig. 2), p. jordani was 

 taken at depths from 50 to 188 fathoms with 

 highest catch rates occurring between 60 and 

 90 fathoms (table 5). 



Small quantities of Pandalopsis dispar were 

 taken over the Continental Shelf and Slope in 

 hauls made between Manhattan Beach, Oreg. 

 and Cape Beale, Vancouver Island. The shrimp

 Pandalus jordani taken off Oregon in 1958 and 1960 



occurred at depths ranging from 50 to 200 

 fathoms. Pandalus platyceros, was also taken in 

 small numbers north of Lapush, Wash., at 

 depths between 50 and 137 fathoms. P. hypsi- 

 notus was not taken in hauls made in offshore 



*As discussed in the text, high abundance of P. jordani 

 and P. borealis was arbitrarily taken as greater than 

 200 pounds per 30 minutes fished for the gulf shrimp 

 trawl and 100 pounds per 30 minutes fished for the beam 

 trawl. High abundance of Pandalopsis dispar was 100 

 pounds per 30 minutes fished for the Gulf shrimp trawl 

 and 50 pounds per 30 minutes fished for the beam trawl. 



waters, but small quantities were captured in 

 the Strait of Juan de Fuca. 



Southeastern Alaska 



Between 1952 and 1956, five cruises were 

 made in the Southeastern Alaska area, mostly 

 in the passages and bays. Explorations ex- 

 tended from Dixon Entrance to Cape Spencer, 

 and sampling was conducted at depths ranging 

 from 13 to 225 fathoms. Pandalid shrimps
