FISHERY BULLETIN: VOL 76, NO 1 



Mark Recovery 



The sampling phase of this study began in 1963 

 and was completed in 1969. Table 6 shows the 

 marks and the age of the marked fish in the 

 fisheries during these years. Sampling and catch 

 estimation procedures are explained under Catch 

 of Marked Fish. Sampling for these fish occurred 

 in the major ocean sport and commercial fisheries 

 from southeastern Alaska to central California, 

 the Columbia River fisheries (Figure 2, Table 7), 

 at parent hatcheries, and certain natural spawn- 



ing grounds (Worlund et al. 1969; Rose and Arp 

 see footnote 3; Arp et al. see footnote 4; Wahle et al. 

 see footnote 5). During the first sampling year, 

 1963, only Washington and Oregon ocean 

 fisheries, Columbia River fisheries, and hatchery 

 returns were examined for marks. In 1964, the 

 sampling was expanded to include most chinook 

 salmon fisheries from Avila Beach, Calif, to Peli- 

 can, Alaska. The Puget Sound sport fishery was 

 not sampled in 1964. The British Columbia purse 

 seine fishery was not sampled in 1966. The sam-
