24 ALASKA FISHERIES AND FUR INDUSTRIES IN 1915. 
August 26 to September 5 at Uganik and the 5,000,000 purchased 
from the Karluk hatchery of the Alaska Packers Association, to make 
up the total of 12,500,000 humpback-salmon eggs shipped in Novem- 
ber, 1914, of which 7,000,000 were consigned to Government hatch- 
eries in Maine and the balance to stations of the Bureau in Wash- 
ington. 
The taking of humpback eggs at Afognak in 1915 extended from 
August 2 to September 21, the total collection beir.g 12,355,000. 
Nearly all the young salmon handled at the Afognak station were 
fed for some time before being planted. Several tons of Dolly Varden 
trout and spawned salmon had been salted down the previous season 
to be used for this purpose. In preparing the food the fish were 
freshened, cooked, pressed into a cake and left under pressure until 
cold; then the food was cut into strips, which were run through a fine 
_ meat grinder several times and finally through a fine screen. The 
young salmon did very well on this diet. The construction of a series 
of 12 rearing ponds, each 20 feet long, 6 feet wide, and 3 feet deep, is 
under way. When these ponds are completed it is anticipated that 
they will be of great assistance in holding and feeding young salmon. 
The ponds are being so built that additional ones can be constructed 
just below them, if necessary. 
Fish-cultural operations in this region are still greatly handicapped 
on account of the volcanic ash resulting from the eruption of Mount 
Katmai in 1912. 
UGANIK. 
The total collections at this pot in 1915 were 2,685,000 red and 
2,461,000 humpback salmon eggs. The loss was 85,000 red and 
61,000 humpbacks; the balance, 2,600,000 red and 2,400,000 eyed 
humpback eggs, was transferred to the Afognak hatchery. The 
Uganik field station was closed October 9. 
SEAL BAY. 
A new collecting and field station was established at Seal Bay on the 
northeast coast of Afognak Island. Some of the equipment used 
here was transferred from the field station operated in 1913 at Eagle 
Lake. Preparations for work at Seal Bay were begun in June and 
operations were brought to a close on October 13, 1915. Collec- 
tions totaled 3,232,100 red and 1,235,000 humpback salmon eggs. 
The loss was 59,100 red and 111,200 humpbacks, thus leaving 3,173,- 
000 red and 1,123,800 humpback eggs, all eyed, which were trans- 
ferred to the Afognak hatchery. 
FORTMANN. « 
The Fortmann hatchery is the largest salmon propagating station in 
the world, its capacity being approximately 110,000,000 red-salmon 
eggs. Itisoperated by the Alaska Packers Association and is located
