FISHERY INDUSTRIES. 35 
FORTMANN. 
This hatchery is owned and operated by the Alaska Packers As- 
sociation. It is located on Heckman Lake, Revillagigedo Island, 
southeastern Alaska. The hatchery was first operated in the season 
of 1901-2, and®it has been operated each season since. The ca- 
pacity of the hatchery is approximately 110,000,000 red-salmon 
eggs. The Alaska Packers Association has recently adopted the in- 
cision method of taking eggs at this hatchery. 
In 1915 there were taken 26,520,000 red-salmon eggs in the period 
from August 21 to November 20. From this take 25,055,000 young 
salmon were released in 1916 in the Naha stream system. The loss 
was 1,465,000, or 5.52 percent. In the same season 600,000 hump- 
back-salmon eggs were taken at this hatchery for experimental pur- 
poses in the period from August 22 to November 22, 1915. From 
this take of eggs 560,000 fish were liberated in 1916. The loss was 
40,000, or 6.66 per cent. 
The take of red-salmon eggs in the period from August 22 to No- 
vember 10, 1916, totaled 62,580,000. This is the largest take of 
eggs since the season of 1911-12 and the fourth largest in the history 
of the hatchery. The average number of eggs per female spawned 
was 2,932. 
KARLUK, 
The take of red-salmon eggs at Karluk in the period from June 26 
to September 29, 1915, was 41,135,000. From this take there were 
released 23,948,000 fry. The loss in eggs and fry was 17,187,000, or 
41.8 per cent. In June, 1916, before it was decided to close the 
hatchery at the end of that month, more than a million red-salmon 
eggs were collected, from which 1,016,000 eyed eggs were transferred 
to the Afognak hatchery in August. 
The Karluk hatchery was built by the Alaska Packers Associa- 
tion in 1896 and has been in operation each season since until closed 
in 1916. It is located at the upper end of Karluk Lagoon at the 
head of tidewater, a distance of about 1? miles from Karluk Spit. 
In the period of its operation about 627,000,000 red-salmon eggs 
were taken, from which approximately 515,000,000 fry were hatched 
and liberated. Prior to the establishment of this station by the 
Alaska Packers Association fish-cultural work was undertaken in a 
limited way in 1891 by several companies engaged in canning opera- 
tions at Karluk, who built a small hatchery near the site subse- 
quently used by the Alaska Packers Association. This small 
hatchery, however, was operated only one season, the take being 
2,500,000 red-salmon eggs, from which because of lack of suitable 
facilities and want of experience only about 500,000 fry were re- 
leased.
