 are being made to hold and feed several million humpback-salmon fry in 1926. 



At the Snag Harbor, Gravina Island, feeding pond, a small number of 

 humpback-salmon fry were held and fed, and 8,180 were marked by removing the 

 right ventral and adipose fins. 



From 2,640,000 chum-salmon eggs taken at Walker's Cove in 1924, 2,501,000 

 fry were hatched and liberated as fingerlings in Ketchikan Creek. 



The egg take this year consisted of 11,415,000 humpback, 320,000 chum, and 

 165,000 red-salmon eggs; and 2,000,000 chinook-salmon eggs were secured from 

 the State of Washington. 



At the Cordova hatchery, 3,242,150 red-salmon fry were hatched from 5,250,- 

 000 eggs collected in 1924, and later were liberated. From 571,000 chinook- 

 salmon eggs secured in 1924 from the State of Washington, 523,500 fry were 

 hatched. In 1925, the number of red-salmon eggs collected was 7,530,300, 

 which produced 7,318,455 fry. 



The 1,429,000 chinook-salmon eggs secured in 1924 from the State of Wash-
