spawned salmon, thus materialy affectinfj the possible take of eggs. 

 The run of salmon was reported as behig equal to that of 1919, or 

 sufficient to have yielded a quantity of eggs far in excess of the 

 capacity of the hatchery. 



FORTMANN. 



The Alaska Packers Association operated the hatchery at Heck- 

 man Lake, on Revillagigedo Island, as heretofore. In 1919 a collec- 

 tion of 18,42(),0()() red-salmon eggs was made, from which 17,()7(),()00 

 fry were hatched and planted in the Naha stream system. The loss 

 during incubation was 1,350,000, or approximately 7.3 per cent. 



Egg collecting in 1920 began September 4 and ended November 11. 

 In that time 18,240,000 red-salmon eggs were obtained. In addition 

 360,000 humpback-salmon eggs were also taken. 



QUADRA. 



The Quadra hatchery on Hugh Smith Lake is owned by the North- 

 western Fisheries Co. Out of the 11,710,000 red-salmon eggs taken 

 in 1919, there were hatched and liberated 11,357,000 fry, the loss 

 being 353,000, or 3 per cent. 



Egg taking in 1920 began August 5 and ended October 28, resulting 

 in a collection of 19,450,000, an increase of more than 71 per cent over 

 1919. 



JUNEAU. 



The Alaska Territorial Fish Commission operates a hatchery in a 

 rented building at Juneau. The plant appears to be modern and is 

 equipi)cd with concrete troughs. No ponds, however, are available 

 for rearing ])urposes. The commission began this work in 1919, and 

 in 1920 the capacity of the hatchery was enlarged to handle 10,000,000 

 salmon eggs. 



In 1919 the commission reported the collection of salmon eggs as 

 follows: Cohos, 10,540,000; chums, 3,425,000; and humpback, 890,- 

 000— a total of 14,855,000. Of the resulting product, 6,815,000 were 

 distributed as eyed eggs and 5,250,000 as fertilized eggs, while 2,110,- 

 000 were distributed as fry. The loss in eyeing and hatching was 

 680,000. The distributions occurred in waters on Admiralty and 

 Baranof Islands and streams on the mainland in the Juneau region. 



In 1920 the commission reported a collection of 17,020,000 salmon 

 eggs, of which 6,460,000 were cohos, 5,250,000 chums, 4,640,000 hump- 

 backs, and 670,000 reds. Of these, irrespective of species, 4,885,000 

 were planted as eyed eggs, 6,500,000 as fertilized eggs, and 2,919,000 

 Avere distributed as fry. The loss of eggs held through the period 

 of incubation was 846,000, or a little more than 8 per cent. By 

 species, these distributions were cohos, 5,730,000; chums, 5,000,000; 

 humpbacks, 3,410,000; and reds, 134,000. The fry remaining in the 

 hatchery totaled 1,900,000. 



GENERAL STATISTICS OF THE FISHERIES IN 1920. 



The total investment in the fisheries of Alaska in 1920 was $70,- 

 986,221, or $3,195,339 less than in 1919. Approximately 89 per cent
