FISHERY INDUSTRIES. 23 
made in the period from September 8 to 16, 1915, when operations 
were discontinued at the request of citizens of Ketchikan, and the 
eges were planted upon the natural spawning grounds. In 1913 a 
substation was operated at Ketchikan, but in 1914 no eggs were 
obtained, as there was no run of salmon in the creek. 
Realizing the advantages of planting fingerlings rather than fry, 
the Bureau has “increased its efforts to feed as many of the young 
salmon at Yes Bay as possible before liberating them. Three rear- 
ing ponds, each 12 by 60 feet in size and 24 feet in depth, constructed 
in 1914, were utilized for this purpose in 1915, Eighty troughs in 
the hatchery were also used for feeding young salmon. The food 
consisted of steelhead trout that were obtained near the hatchery 
and adult salmon which had been salted down after their eggs were 
taken the previous fall. These salmon were thoroughly freshened by 
being placed in running water for 24 hours or more. The food was 
cooked, ground, pressed dry, and after grating and screening was ready 
tobe fed, It appeared to give satisfactory results. Some difficulty 
was experienced with the salmon held in the ponds when the water 
warmed up to an unusual degree in the month of June. Most of the 
fingerlings then remaining on hand were accordingly planted in the 
lake. 
A watchman was stationed on Yes Bay, beginning July 13, 1915, 
and continuing through the run of the red salmon, to see that the 
order closing the bay to commercial fishing was fully observed. 
ABOGNAK. 
The collection of red-salmon eggs at the Afognak station from 
August 1 to September 29, 1914, aggregated 7,390,000. From these 
eggs there was planted in the period from December, 1914, to May, 
1915,a total of 5,444,830 young salmon, most of which were of the fin- 
gerling size. The take of red-salmon eggs at this station in 1915 con- 
tinued from August 7 to September 30, during which time 8,183,000 
eggs were obtained. 
A shipment of 15,000,000 red-salmon eggs in 65 cases from the Yes 
Bay station arrived at Afognak village December 9 and was placed 
in the Bureau’s warehouse at Litnik Bay. On account of unfavora- 
ble weather and great difficulties in transporting the egg cases over 
the ice, it was not until December 22 that the last of the eggs reached 
the hatchery. Although made ready for shipment at Yes Bay on 
November 23, these eggs were in good condition with the exception 
of one case in which there had been some premature hatching. 
From August 4 to September 14, 1914, there were taken at Afognak 
6,574,600 humpback-salmon eggs. From these eggs 119,480 young 
salmon were planted in the winter and spring of 1914-15. Most of 
the eggs from this collection went with the 2,534,000 collected from
