266 U. S. BUREAU OF FISHERIES 
The departmental regulations prohibited commercial fishing for 
salmon in Karluk waters before 6 a. m. June 15 and after 6 p. m. 
September 15, and in addition from August 21 to September 5 the 
weekly closed period in the district was extended from 6 p. m. Sat- 
urday to 6 a. m. Wednesday of each week in order to permit a larger 
percentage of the red salmon to escape. The commercial take of 
red salmon from the Karluk run was 2,131,616, or 46 per cent of 
the total. Ray S. Wood was in charge of counting operations at the 
Karluk weir, under the direction of H. H. Hungerford. 
A special study of the run at Karluk was made during the season 
by Dr. W. H. Rich. A large migration of red salmon fingerlings 
down river was noted in May, June, and July. Approximately 
47,000 of the early migrants were marked by clipping two fins. 
temporary web weir was constructed about 8 miles below Karluk Lake, 
more particularly for the handling of humpbacks if they ascended in 
any considerable numbers; but as the run was very small there was 
no great need of this supplementary weir, and its operation was 
discontinued. On July 19, 100 ascending red salmon were marked 
at the lower weir by attaching a piece of white tape to their tails. At 
the upper weir 52 of the salmon thus marked were noted, the time of 
ascending the intervening 16 miles varying from 2 to 9 days. Some 
of the marked salmon probably lost the tape and others may have 
passed through the weir unnoticed. 
ALITAK SALMON COUNT 
Weirs chiefly for counting red salmon were again maintained in 
two streams tributary to Olga Bay. The one at the upper station 
was completed on May 16 and the cannery-station weir on May 20. 
Red salmon began to ascend on May 22 and continued until Septem- 
ber 30, when the weirs were removed. ‘There were also a few red 
salmon that had not ascended at that time. At the upper station 
the escapement was 789,947 reds and at the cannery station 105,142 
reds, a total of 895,089. In addition, 10,866 cohos and 663 humpbacks 
were counted through the upper station weir and 2,900 cohos and 
8,327 humpbacks through the cannery-station weir, a total of 13,766 
cohos and 8,990 humpbacks. As these latter species spawn chiefly 
elsewhere, the counts at the weirs do not indicate the total escape- 
ment. There is also a run of red salmon into Horse Marine Lagoon, 
where no counting weir is maintained. It was estimated that ap- 
proximately 25,000 red salmon spawned in the lake and streams at 
its head, which bring the figures for the total escapement of reds in 
Alitak Bay waters to considerably over 900,000. 
Commercial fishing in Alitak Bay and its tributary waters was pro- 
hibited prior to 6 a. m. June 15, to which time there had been an 
escapement of 80,537 red salmon. The commercial catch approached 
the recorded escapement on July 31, and a trap in Moser Bay was 
ordered closed at 6 p.m. on July 31. Another trap in the same waters 
was closed at 6 p. m. August 7, and both remained closed until 6 a. m. 
August 16. The total reported catch of red salmon in the district 
was 323,596. No commercial fishing was carried on after Septem- 
ber 18. 
Homer H. Whitford was in charge of operations for the bureau.
