32 ALASKA FISHERIES AND FUR INDUSTRIES IN 1916. 
HATCHERY OPERATIONS. 
YES BAY. 
In September, 1915, a collection of 72,000,000 red-salmon eggs was 
made at the Bureau’s station at Yes Bay, from which 52,319,500 fry 
were hatched. Of this number, 32,915,000 were liberated as fry in 
the winter of 1915-16 and 19,402,500 as fingerlings in 1916, there being 
a loss of 2,000 fingerlings. Shipments of eggs were made in October, 
1915, as follows: Oregon Fish Commission, 3,000,000; Quinault Lake, 
Wash., 50,000; and Anderson Lake, British Columbia, 50,000. In the 
report of Alaska Fisheries and Fur Industries for 1915 it was indicated 
that 100,000 eggs were transferred to Quinault Lake, but in reality 
50,000 of these were diverted at Seattle and sent to Anderson Lake. 
In November, 1915, a shipment of 15,000,000 red-salmon eggs was 
sent to the Afognak station. The total loss of eggs and fry at Yes 
Bay was 1,580,500, or a little more than 2 per cent. 
Spawning operations at Yes Bay in 1916 began September 1 and 
ended October 2. During that period 58,000,000 red-salmon eggs 
were taken. From this collection 2,000,000 eggs were transferred in 
October, 1916, to the Bonneville, Oreg., station of the Oregon Fish 
Commission. 
A temporary substation for the collection of humpback-salmon eggs 
was established at Smeaton Bay, but there was a very small run of 
humpbacks in that locality and only 29,600 eggs were obtained, which 
were planted on the near-by spawning beds. 
The Bureau’s efforts to rear salmon to fingerling size before planting 
were continued at Yes Bay, but facilities for holding the young fish 
are still too limited to admit of more than part of the station’s output 
being carried beyond the fry stage. The young fish were fed on 
raw salt salmon ground up after being freshened. The results 
obtained from the use of this food were better than in 1915, when 
cooked salmon was used. It was also noted that the young fish 
thrived better in the hatching troughs than in the rearing ponds. 
The usual patrol of Yes Bay was maintained during the run of red 
salmon in order to enforce the order closing those waters to commer- 
cial fishing. . 
AFOGNAK, 
Tn 1915 the collection of red-salmon eggs at Afognak was 6,353,000. 
In the Bureau’s Alaska Fisheries and Fur Industries Report for 1915, 
it was inadvertently stated by reason of duplications in returns from 
the station that the take was 8,183,000. The collection in 1915 was 
augmented by the transfer of 2,600,000 eyed eggs from Uganik, 
3,173,000 from Seal Bay, and 15,000,000 from the Bureau’s station 
at Yes Bay, making a total of 27,126,000 red-salmon eggs handled 
at this station during the season of 1915-16. From this number
