p. platyceros was not commonly taken in the 

 central Alaska area, and Port Dick was the 

 most northwesterly point at which it was 

 captured at all. 



Pandalopsis dispar was caught throughout 

 the central Alaska area. The best catches 

 occurred in Nuka Passage and Kukak Bay. 

 Other places producing good catches of this 

 species were Aialik Bay, Resurrection Bay, 

 Day Harbor, south of Harris Bay, as well as 

 Port Dick, Kachemak Bay, East Arm of Nuka 

 Bay, off Cape Douglas, Ragged Island, Marmot 

 Bay, Shelikof Strait, and Uyak Bay. P. dispar 

 was found in central Alaskan waters at depths 

 from 22 to 233 fathoms with the better catches 

 generally occurring from about 60 to 119 

 fathoms (tables 15-20). 



Alaska Peninsula 



In 1957 the waters adjacent to the Shumagin 

 Islands and the Alaska Peninsula from Stepo- 

 vak Bay to Unalaska were explored, and 

 sampling was conducted at depths ranging 

 from 19 to 124 fathoms. 



Pandalus borealis was again dominant, and 

 the abundance of P. borealis (up to 3, 500 pounds 

 per 30 minutes of fishing) was the greatest 

 found in any area explored. Highest catches 

 occurred in Pavlof Bay. High abundance was 

 also noted in Beaver Bay, Balboa Bay, near 

 Seallion Rocks, and Stepovak Bay (fig. 5). 

 P. borealis was taken at depths ranging from 30 

 to 99 fathoms, with the best catches between 

 40 and 79 fathoms (table 21). 



P. hypsinotus also occurred in fair quanti- 

 ties. Good catches were made in Beaver Bay, 

 Balboa Bay, Pavlof Bay, Stepovak Bay, and 

 near Seallion Rocks. P. hypsinotus was taken 

 at depths of 30 to 99 fathoms, with highest 

 catches from 40 to 79 fathoms (table 22). 



Paadalopsis dispar was taken in fair quanti- 

 ties. CJood catches were made near Seallion 

 Rocks. Relatively high abundance was also 

 noted in Pavlof Bay, Beaver Bay, and off 

 Balboa Bay. Highest catches of this species 

 were made in 50 to 79 fathoms (table 23), 



Pandalus platyceros was not taken in 

 waters adjacent to the Alaska Peninsula.
