PACK IN CERTAIN DISTRICTS 



Statistics of the salmon pack are again presented for subdivisions of 

 the three main districts of Alaska, and comparison is made with simi- 

 lar statistics for 1930. Where the pack at a given cannery is made up 

 of fish from more than one district, as in the case of that at certain 

 Cordova canneries which pack fish caught both in Prince William 

 Sound and in the Copper River area or at various plants in south- 

 eastern Alaska which draw for their supply on the catch of more than 

 one district, due segregation has been made in order to credit each 

 district with the pack from salmon caught therein. These districts 

 are described as follows: 



WESTERN ALASKA 



Bristol Bay. — The Bering Sea shore, east and north of the Ugashik River. 

 Port Moller and Herendeen Bay. — Port Moller, Herendeen Bay, and Nelson 

 Lagoon. 



CENTRAL ALASKA

 Shumagin Islands. 



Chignik. — Canneries located at Chignik. 



Kodiak-Afognak Islands. — Kodiak, Spruce, and Raspberry Islands. 



Cook Inlet. — The shores of Cook Inlet. 



Prince William Sound. — Extends from Resurrection Bay to Point Whitshed.
