Salmon fishery.—Regulations Nos. 6 and 7 are amended to permit commercial 
salmon fishing, except by traps, from 6 o’clock antemeridian October 1 to 6 o’ clock 
postmeridian October 20. 
Revised regulations effective in 1940 for the protection of the com- 
merical fisheries of Alaska were issued by the Secretary of the Interior 
under date of January 4, 1940, copies of which may be obtained, with- 
out cost, upon application to the Fish and Wildlife Service, Washing- 
font D.C, 
ANNETTE ISLAND FISHERY RESERVE 
As in the previous year, the Annette Island Canning Co. operated 
the salmon cannery at Metlakatla under its lease from the Department 
of the Interior. 
Kight salmon traps were operated by the company, the catch of 
which totaled 878,523 salmon of all species, and 11,845 salmon taken 
by seines and gill nets in the waters of the reservation were purchased 
from natives. In addition, 462,450 salmon were purchased from inde- 
pendent operators of seines, gill nets, and traps outside the reserve. 
Ali these fish were packed in the company’s plant. In the operation 
of the cannery and fish traps employment was given to 51 whites and 
319 natives. 
The estimated profits to the Metlakatlan Indians of the reserve on 
the cannery operations for 1939 under the provisions of the lease 
amounted to $58,500. 
STREAM IMPROVEMENT 
No extensive program was carried on in 1939 for the clearing of 
salmon streams to assure the accessibility of all spawning areas to 
brood fish. The only work of this kind, other than that performed by 
Bureau employees in connection with fishery patrol duties, was that 
conducted in the Cook Inlet area under an allotment of funds from 
the Territorial appropriation and contributions of the local salmon 
packers for clearing salmon streams. Two men were employed in 
that area for about a month, examining conditions of the spawning 
beds in tributaries of Knik Arm, and a third man was engaged for a 
short time in similar work on the Kenai River system. A number 
of beaver dams in these localities were opened to permit the passage 
of salmon to the spawning grounds. 
The removal of log jams and other debris that prevented the ascent 
of salmon was reported for a few districts. Some work was done 
on the stream connecting the lower and upper lakes at Kaflia Bay, 
which stream is shallow and unusually rapid. A definite channel was 
constructed and crude resting pools were made at frequent intervals 
to facilitate the progress of spawning fish. 
CONTROL OF PREDATORY TROUT 
In some parts of Alaska which are sparsely settled and infrequently 
visited by sport fishermen, Dolly Varden trout are exceedingly 
numerous and are regarded as unmistakable enemies of the commer- 
cially valuable fish, inasmuch as they feed voraciously on salmon eggs 
and fry. To curb. their depredations, therefore, the Territorial 
Legislature for many years has appropriated funds, matched by con- 
tributions of local salmon packers, for the payment of bounty on 
Dolly Varden trout in certain red-salmon spawning streams, notably
