ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1925 107 



AFOGNAK 



The rebuilding of the Federal hatchery at Afognak was finished 

 in time to collect eggs during the season of 1925. Spawning oper- 

 ations began on August 3 and continued to September 15, during 

 which time 11,000,000 red-salmon eggs were taken. Fry were not 

 distributed during the year as no eggs were collected in 1924. Atten- 

 tion was given to the destruction of predatory trout, which are 

 abundant in Litnik Lake and are believed to be mainly responsible 

 for the decline of the run of salmon. From July to December, 

 54,100 Dolly Varden trout were taken in traps and beach seines. 



m'donald lake 



At the Federal salmon hatchery on McDonald Lake, 27,382,000 

 red-salmon fry were hatched from 30,080,000 eggs taken in 1924, 

 a loss of about 9 per cent, and these were liberated later as fry and 

 fingerlings. Extreme cold weather and the partial freezing of the 

 water supply in December and January necessitated the planting of 

 6,300,000 fry in order to avoid losing them. All other plants con- 

 sisted of No. 1 and No. 2 fingerlings, and were made from June to 

 October. 



In the period from September 7 to October 6, 1925, 39,680,000 red- 

 salmon eggs were taken. On November 20, a shipment of 8,645,760 

 eyed eggs was made, 5,645,000 to the bureau's station at Baker Lake, 

 Wash., and the remaining 3,000,760 to the Oregon State Fish Com- 

 mission. 



HECKMAN LAKE (FORTMANN) 



The Alaska Packers Association liberated 11,005,000 red-salmon fry 

 from its Fortmann hatchery on Heckman Lake in 1925, which were 

 hatched from 11,640,000 eggs taken in 1924, a loss of 5.45 per cent. 

 In addition, 805,000 humpback-salmon fry, hatched from eggs 

 collected in 1924, were released. Egg taking began on September 5 

 in 1925 and ended on November 16, during which time 16,920,000 

 red-salmon eggs and 4,680,000 humpback-salmon eggs were taken. 



HUGH SMITH LAKE (QUADRA) 



The Northwestern Fisheries Co. liberated 19,430,000 red-salmon fry 

 from its hatchery near Boca de Quadra in 1925, hatched from 20,- 

 050,000 eggs taken in 1924, a loss of 3 per cent. In 1925, the hatchery 

 was filled to capacity with 20,240,000 red-salmon eggs taken from 

 August 7 to September 9. 



TERRITORIAL HATCHERIES 



Under date of March 29, 1926, Patrick Gildea, secretary of the 

 Alaska Territorial Fish Commission, submitted a general outline of 

 the commission's fish-cultural work in Alaska in 1925, as follows: 



Hatchery operations. — At the Ketchikan hatchery, 1,930,000 chinook-salmon 

 fingerlings were reared, which were liberated in August. These were hatched from 

 2,000,000 eggs that were obtained in 1924 from the State of Washington. Ten 

 thousand of these chinook fingerlings were marked by removing the dorsal and 

 adipose fins. Some of these fry are still in Ketchikan Creek. From 3,477,000 

 eggs taken in 1924, 2,946,000 humpback-salmon fingerlings were produced. Most 

 of these were taken to the salt-water feeding pond at Ponds Bay, Duke Island. 

 They did very well for a time and were liberated during the latter part of March,
