spawned salmon, thus materialy affecting the possible take of eggs. 
The run of salmon was reported as being 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 18,420,000 red-salmon eggs was made, from which 17,070,000 
fry were hatched and planted in the Naha stream system. The loss 
during incubation was 1,850,000, 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 11,857,000 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 
equipped with concrete troughs. No ponds, however, are available 
for rearing purposes. 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 for ized eges, 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 
were 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, 184,000. 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
