ANAN SALMON COUNT 



The counting of salmon that escape capture was begun in 1925 at 

 Anan . Creek in southeastern Alaska, where an important run of 

 humpback salmon occurs. A weir was erected at a point midway 

 between the two falls in the creek, where the latter was 180 feet in 

 width. The rack was completed by June 5, and the first humpback 

 salmon were counted through it on June 17. The run continued 

 until September 8 and the total count was 261,339 humpbacks. 

 In addition, 75 red salmon, 87 kings, 848 cohos, 140 chums, and 352 

 steelheads passed through the weir during that period. In compari- 

 son with this escapement, five traps operated a short distance below 

 Anan Creek took 150,988 humpback salmon. Figures showing the 

 catch by other kinds of apparatus in the same waters are not avail- 

 able.

John W. Gardner of the Yes Bay hatchery was detailed to supervise 

 the construction of the weir, and Walter J. Larson later took charge 

 of counting operations. 



SALMON TAGGING 



The tagging of salmon was continued in 1925 in southeastern 

 Alaska and the Port Moller district for the purpose of obtaining 

 further data with regard to the migration routes of these fish. 



In southeastern Alaska the work was carried on in six general 

 localities, and all species except the king salmon were handled. The 

 numbers of salmon tagged at the various localities were as follows: 

 Icy Strait, 1,384; Kingsmill Point, 1,944; Ruins Point, 3,243; Tree 

 Point, 1,198; Cape Chacon, 2,759; and the west coast of Prince of 

 Wales Island, 3,117; a total of 13,645 fish. Of these, 1,165 were red 

 salmon, 2,394 chums, 8,544 humpbacks, and 1,542 cohos (including
