there were planted in the period from February to June, 1916, 
11,833,200 fry and 11,100,440 red-salmon fingerlings, or a total of 
22,933,640 young salmon. 
The red-salmon spawning season of 1916 began July 28 and ended 
October 18, in which period 17,044,000 eggs were taken. This num- 
ber was increased by the transfer in August of 1,016,000 eyed eggs 
from the Karluk hatchery of the Alaska Packers Association, 681,000 
from Uganik, and 4,600,000 from Seal Bay in October, thus making 
a total of 23,341,000 red-salmon eggs incubated at Afognak in the 
winter of 1916-17. : 
In October and November, 1916, there were planted 1,401,000 fry 
hatched from these eggs, and at the end of December there remained 
on hand 7,200,000 eggs and 13,021,000 fry. 
_ In 1916 the first humpback-salmon eggs were taken August 11 and 
the last on September 11. During that period 25,310,000 eggs were 
obtained, which is more than double the take of 1915, when 12,355,000 
were collected. The transfer in October of 10,321,000 eyed eggs 
from Uganik and 2,820,000 from Seal Bay increased the total number 
handled at Afognak to 38,451,000. From this number a shipment 
of 16,000,000 eggs was made to the Bureau’s stations in the New 
England States and in Washington and Oregon, each region receiving 
8,000,000 eggs. 
Plants of humpback-salmon fry in November and December agegre- 
gated 15,756,000, while 3,095,000 eggs were lost, leaving a balance of 
3,600,000 eggs on hand at the end of the year. Additional plants of 
fry hatched from eggs collected in 1915 totaled 2,336,500, thus mak- 
ing a grand total of 18,092,500 young humpback salmon released at 
Afognak in 1916. 
A matter which invites comment is the greatly lengthened red- 
salmon egg-collecting period each year since the eruption of Mount 
Katmai in 1912 as compared with the period of such operations prior 
thereto from the beginning of fish-cultural work on Afognak Island 
in 1908. That year the first red-salmon eggs were taken on July 27, 
the maximum take was made August 17, and the last eggs were col- 
lected on August 26. The spawning season covered a period of 31 
days. This was the approximate length of each season to and in- 
cluding that of 1912. Beginning with 1913 there has been a marked 
variation from this condition. Although the first eggs secured in 
1913 were taken July 31, about the usual time, the last collection was 
not made until October 10, the length of the season being 72 days, 
almost two and one-half times that of 1910, the shortest season on 
record at this station. After 1913 the seasons were much longer 
than they had been in previous years, culminating in 1916 in one of 
‘83 days’ length, beginning as it did July 28 and closing October 18.
