ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1924 117 



handled, from which 2,952,000 humpback-sahiion fry, 2,571,000 

 chum-salmon fry, and 1,949,000 chinook-salmon fry were hatched. 

 An experiment in feeding 100,000 humpback-salmon fry in a salt- 

 water pond at the Ketchikan hatchery early in 1924 was very satis- 

 factory, and arrangements are being made to conduct salt-water 

 feeding on a larger scale in 1925. 



At the Cordova hatchery 5,250,000 red-salmon eggs and 571,000 

 chinook-salmon eggs were handled, and at the Seward hatchery 

 1,015,000 red-salmon eggs and 1,429,000 chinook-salmon eggs were 

 taken care of. At the time of the report, on March 1, 1925, egg 

 hatching had not been completed at these two hatcheries. The 

 bureau cooperated with the Territorial Fish Commission by furnish- 

 ing transportation from Cordova to Latouche for 1,700,000 red-salmon 

 eggs, which were planted at Eshamy. 



The chinook-salmon eggs handled at all three hatcheries were 

 received from the State of Washington. 



In connection with the operation of the Territorial hatchery near 

 Cordova, a weir was maintained at the outlet of Eyak Lake for the 

 counting of red salmon ascending to the spawning beds. Counting 

 began on June 6 and continued until September 21, the weir being 

 dismantled on vSeptember 30. Reports received indicate that during 

 this period 44,245 red salmon passed through the weir. 



OTHER HATCHERY OPERATIONS 



Representatives of the Washington State Fish Commission col- 

 lected humpback-salmon eggs and maintained an eying station at the 

 head of Fidalgo Bay, on Prince William vSound, in the season of 1924. 

 Egg taking began on August 8 and ended August 28, during which 

 period 21,320 female humpback salmon were taken. Of the 42,217,100 

 eggs secured from these fish, 3,097,100 were lost and the remaining 

 39,120,000 eyed eggs were forwarded to Seattle in four shipments 

 late in September and early in October. 



TROUT OPERATIONS 



The department of fisheries and game and the game commission 

 for King County, both of the State of Washington, engaged in collect- 

 ing trout eggs in southeastern Alaska early in the season before the 

 run of salmon began. The department of fisheries and game 

 operated at Eva Lake, tributary to Peril Strait, and secured about 

 200,000 cutthroat-trout eggs, of which 50,000 were hatched and 

 planted in Eva Lake and the remainder delivered to the Forest 

 Service. The game commission for King Count}^ operated at a stream 

 tributary to Thorne Arm, indenting the southern shore of Revillagi- 

 gedo Island, and took 568,000 steelhead-trout eggs, which were 

 shipped to the State of Washington.
