Table 24. — Chinook-salmon fingerlings marked at Bonneville hatchery during the fall of 19SS, when 

 approximately 12 months old, and recovered during the seasons of 1924, 1925, and 1926 — Contd. 



One of the 5-year-olds was caught by troll in the ocean off the coast of south- 

 eastern Alaska, approximately 600 miles from the mouth of the Columbia River. 

 This record is of much interest, because it corroborates data obtained from other 

 sources showing that salmon travel great distances in the ocean. The tagging of 

 adult salmon caught by troll in the ocean has shown that chinooks found as far north 

 as Queen Charlotte Islands, British Columbia, may later enter the Columbia River 

 (WiUiamson, 1927). This record extends the known range of the Columbia River 

 chinooks to include southeastern .\laska. 



In this experiment we find, for the sixth time, the progeny of the spring run of 

 salmon entering fresh water on their spawning migration at a definite and regular 

 time of the year. As in the other similar experiments, the majority of the recoveries
