INTRODUCTION 
The extensive salmon-tagging experiments which have been conducted in Alaska 
since 1922 were continued during 1929 in central Alaska, under the general direction 
of Dr. Willis H. Rich. The investigation was intended to determine the direction of 
migration from the entrances of Cook Inlet and Prince William Sound, and from 
prominent points by which the fish pass to reach the spawning grounds of those regions. 
The method of tagging has been adequately described in previous reports. 2 
Because those areas are comparatively small and the fish entering them are largely 
bound for local spawning grounds, it seemed unnecessary to tag a very great number 
of salmon. An effort was made, however, to conduct the operations early in the 
season and again during the height and toward the end of the run, to determine 
whether the migration and distribution of the fish varied during the season. 
The accompanying map will serve to show the general geography of central Alaska; 
and the following list includes all minor localities from which tagged fish were recorded.
