SALMON TAGGING IN ALASKA, 1926

By far the greater number of these fish went north and were taken in Revilla- 

 gigedo Channel, Boca de Quadra, and Behm Canal. It is especially interesting to 

 note the very large numbers taken in Boca de Quadra and at the Boca de Quadra 

 hatchery. It is evident that this is one of the most important producing areas for 

 the red-salmon runs that strike in at Cape Fox early in the season; and from the fact 

 that so many of the tags were taken at the hatchery it seems possible that the hatchery 

 operations are responsible for this unusual productiveness. In support of this we 

 have the fact that the runs to the hatchery have been increasing for a number of

 this and the other similar figures the width of the lines indicating the routes of salmon 

 migration show roughly the relative importance of each route 



years. A smaller, though still important, component of the early run at Cape Fox 

 is composed of red salmon derived from the Nass Eiver. Forty-six tags were reported 

 from the Nass and from the waters immediately adjacent and 35 of these were taken 

 in the river itself. Eight others were taken elsewhere in British Columbia, including 

 two taken in the Skeena River. 



In the experiments of 1924 and 1925 the tagging in the Cape Fox region was 

 done later in the season (July 30 to August 9), and but few red salmon were included, 

 the total number being only 91. The recaptures numbered but 20, 10 of which came
