not completed until after the close of the spawning season. Subse- 

 cjuently a shipment of 5,000,000 eyed red-salmon eggs was made 

 from Afognak, from which 4,025,000 young salmon were produced 

 and liberated in McDonald Lake. In 1921 the collection of red- 

 salmon eggs aggregated 51,000,000. The egg-taking season ended 

 September 27. 



AFOGNAK. 



From the collection of 62,300,000 red-salmon eggs obtained at 

 Afognak in 1920 shipments of 5,000,000 and 2,340,500 eyed eggs were 

 made, respectively, to the bureau's stations at McDonald Lake, 

 southeast Alaska, and at Quinault, Wash., and 3,000,000 eyed eggs 

 were shipped to the Oregon State hatchery at Bonneville. Out of 

 the remaining 51,959,500 there were liberated 47,808,000 fry and 

 fingerlings in Afognak Lake and tributaries. The loss of eggs and 

 fry was 6.66 per cent. In the season of 1921 a total of 53,835,000 

 red-salmon eggs was collected. The run of salmon was good, and a 

 larger take of eggs might have been made had not high water inter- 

 rupted operations. The season opened in July and closed Septem- 

 ber 20. 



FORTMANN. 



The Fortmann hatchery of the Alaska Packers Association on Heck- 

 man Lake, Revillagigedo Island, liberated 17,375,000 young red 

 salmon in Naha stream and lakes, out of 18,240,000 eggs collected in 

 1920. The loss of eggs was 4.74 per cent. In addition 345,000 

 humpback-salmon fry were hatched and planted in the same water 

 system. Egg taking in 1921 began August 26 and ended November 

 21. In that period 13,380,000 red and 900,000 humpback salmon 

 eggs were collected. 



QUADRA. 



The hatchery of the Northwestern Fisheries Co., on Hugh Smith 

 Lake, produced and released 18,913,000 red-salmon fry out of a total 

 collection of 19,450,000 eggs in 1920. The loss was 2.7 per cent. 

 Spawn taking in 1921 began in August and ended November 14. 

 In that time 9,985,000 red-salmon eggs were taken. 



JUNEAU AND CORDOVA. 



The Alaska Territorial Fish Commission continued fish-cultural 

 work in the Juneau field during 1921 by collecting 6,300,000 coho and 

 humpback salmon eggs. Of this number the commission reports 

 that 5,300,000 were coho-salmon eggs, of which 1,000,000 were planted 

 as eyed eggs and 4,050,000 were hatched and liberated as fry. The 

 reported loss was 250,000 eggs and fry, or approximately 4.71 per 

 cent. The remaining 1,000,000 eggs of the total collection were 

 taken from humpback salmon. Out of this lot 500,000 fry were pro- 

 duced and distributed, 450,000 were planted as eyed eggs, and 50,000, 

 or 5 per cent, were lost. Plants of eggs and fry were made in Baranof 

 Lake, at Warm Springs Bay, and in the streams of Admiralty and 

 Douglas Islands and oi the mainland near Juneau. 



Fish-cultural work was also inaugurated at Eyak Lake, near Cor- 

 dova, by the construction of a battery of troughs for use as an eyeing
