of bounties on predatory trout that feed upon salmon eggs and fry. 
This work is administered by the Bureau in connection with the regular 
patrol of fishing grounds. Studies of the Dolly Varden trout were con- 
tinued in the Kodiak area, and considerable numbers of these predators 
were destroyed by employees in charge of salmon-counting weirs. 
PRODUCTS OF THE FISHERIES 
The total production of the Alaska fishery industry in 1939 was some- 
what less than in the previous year, notwithstanding an increase in the 
number of plants and persons employed in the industry. The total 
output was 368,536,000 pounds, valued at $40,104,000, as compared 
with 446,664,000 pounds, valued at $42,870,000, in 1938. The estimated 
value of the 1939 catch to the fishermen was about $11,321,000, or 
approximately $719,000 less than in the preceding year. There were 
30,572 persons employed in the various branches of the industry, as 
against 28,084 in 1938. 
Salmon products represented 73 percent in volume and 91 pentane in 
value of the total fisheries output in Alaska in 1939. Ninety-three per- 
cent of the salmon products consisted of canned salmon, the pack 
amounting to 5,263,000 cases, or 252,631,000 pounds, valued at $34,- 
441,082. Red salmon comprised 387 percent and pinks 48 percent of 
the total pack of canned salmon, as against 37 percent and 47 percent, 
respectively, in 1938. As compared with the pack in the preceding 
year, the output of canned salmon in 1939 showed a decrease of about 
23 percent in quantity and about 6 percent in value. One hundred and 
nine canneries were operated in Alaska in 1939, or 11 more than in 
the previous year, and the number of persons employed in the salmon- 
canning industry increased from 22,280 in 1938 to 24,921 in 1939. 
There were 21 herring plants operated in 1939, as compared with 17 
in the previous year. Products of the herring fishery were valued at 
$2,090,000, an increase of about 2 percent over 1938. Halibut landings 
were slightly less in 1939 than in the previous year, and many of the 
minor fishery products, including clams, shrimp, and crabs, also were 
less than in 1938. 
ALASKA FUR-SEAL SERVICE 
General Activities 
Sealing and foxing operations were carried on as usual by the native 
inhabitants of the Pribilof Islands under the supervision of the Bu- 
reau’s staff. Approximately 80 additional natives from the mainland

with fur-seal activities, and 25 employees of the Fouke Fur Co. also
