HATCHERY OPERATIONS 



M DONALD LAKE 



The Federal salmon hatchery at McDonald Lake produced and 

 liberated 21,817,800 young red salmon from the 25,550,000 eggs taken 

 in 1923, a loss of 14.6 per cent. There was a heavy loss of eggs 

 attributed to the water being supercharged with air, causing bubbles 

 to form on the eggs and float them to the lower end of the baskets, 

 where congestion resulted. 



In the period from September 8 to 25, 1924, 30,080,000 red-salmon 

 eggs were collected at this station. In addition, from 15,000,000 to 

 20,000,000 red-salmon eggs were spawned naturally in waters adja- 

 cent to the station. 



HECKMAN LAKE (FORTMANN) 



The Alaska Packers Association liberated 13,875,000 red-salmon fry 

 from its Fortmann hatchery on Heckman Lake in 1924, hatched from 

 the 1923 take of 15,480,000 eggs, a loss of eggs of 10.4 per cent. In 

 addition, 1,150,000 humpback-salmon fry, hatched from eggs collected 

 in 1923, were released. Egg taking in 1924 began August 22 and 

 ended November 18, during which time 11,640,000 red-salmon eggs 

 and 900,000 humpback-salmon eggs were taken. 



HUGH SMITH LAKE (QUADRA) 



The Northwestern Fisheries Co. operated its salmon hatchery as 

 usual on this lake on the mainland near Boca de Quadra. Egg col- 

 lecting began August 7 and ended October 7, the total take being 

 20,050,000 red-salmon eggs, which was the full capacity of the hatch- 

 ery. The take in 1923 was 17,885,000 red-salmon eggs, from which 

 17,234,000 fry were hatched and liberated in the headwaters of Sock- 

 eye Creek, a loss of 651,000, or 3.6 per cent. 



TERRITORIAL HATCHERIES 



Information received from the Governor of Alaska in regard to the 

 three salmon hatcheries operated by the Territory is as follows: 



At the Ketchikan hatchery 3,447,000 humpback-salmon eggs, 

 2,640,000 chum-salmon eggs, and 2,000,000 chinook-salmon eggs were
