UGASHIK SALMON COUNT 



A weir for the counting of ascending spawning salmon was again 

 maintained on the Ugashik River in 1927, at the same location as 

 in the previous year. The first red salmon were tallied on June 23, 

 and counting continued through August 15, v/hen a total of 443,283 

 had ascended. In addition, 22 kings, 26 humpbacks, 89 chums, and 

 22 cohos were counted during the season. In the work of extermi- 

 nating predatory enemies of salmon, 29,200 Dolly Varden trout were 

 taken from Ugashik streams, including a few from Becharof Lake. 



Commercial fishing began June 23 and stopped July 16. The 

 reported catch of red salmon from the Ugashik run was 311,995. 



Operations at the weir were in charge of Henry McFadden. 



ANAN SALMON COUNT 



Installation of the weir at Anan Creek was begun on May 16 and 

 completed on May 30, progress having been hampered considerably 

 because of high water. On the date of completion 49 steelheads 

 passed through the weir, but the first humpback salmon did not 

 appear until June 22. The numbers ascending the stream gradually 

 increased until July 7, on which date 988 humpback salmon were 

 counted. A decline followed for a few days, and again the run 

 increased, reaching its peak on July 29, when 1,859 salmon passed 

 through. From that time on there was a decrease to September 24, 

 when all fish ceased running. The total count of humpbacks until 

 the weir was removed on September 24 was 44,936. Other species 

 counted through were 2,002 cohos, 280 chums, 132 reds, 69 kings, and 

 685 steelheads. Walter J. Larson was in charge of the construction 

 of the weir and of counting operations throughout the season. 



SALMON TAGGING 



To develop further information regarding migration routes, and 

 especially to extend the investigation to districts in southeastern 

 Alaska not previously covered, the tagging and releasing of salmon 

 was again undertaken in 1927. The scarcity of fish, however, and 

 the consequent short commercial season in certain districts prevented 

 carrying on the work to the extent originally planned. The total 

 number tagged in southeastern Alaska was 5,148, of which 4,668 were 

 from traps and 480 were troll-caught fish. 



The numbers of salmon tagged and released from traps in the various 

 localities were as follows: Inian Islands, 500; Pleasant Island, 498; 

 Parker Point, 299; Marble Bluffs, 200; Hourigan Point, 699; Carroll 

 Island, 75; Cape Bendel, 499; Point Hobart, 200; Point Colpoys, 

 999; Cape Decision, 299; Dall Head, 150; and Nelson Cove, 250; a 

 total of 4,668. Of these, 747 were red salmon, 901 chums, 208 cohos, 

 2,795 humpbacks, and 17 kings. Warden F. G. Morton was in 

 charge of the work, which continued from July 1 through August 6. 



The tagging of salnion taken in trolling operations was carried on 

 by Hugo W. Frederickson in waters on the west coast of Baranof 

 Island. During the season 480 salmon were tagged, of which 382 

 were kings and 98 cohos. 



Late reports indicate that there have been 1,424 recaptures, or 

 about 30 per cent, of salmon tagged and released from traps. Recap-
