ALASKA FISHERY AND FUK-SEAL INDUSTRIES, 19 3 3 261 



Before the seaward mifrratiou of youiinj red salmon boo:an in tlie 

 spring a considerable number of predatory trout were caught by traps 

 and seines. Forty thousand red-salmon fingerlings were marked at 

 Karluk Lake in i\Iay and June. 



Charles P. Turner was in charge of this weir, under the direction 

 of Warden Howard H. Hungerford. 



CIIIGXIK RIVER 



The site of the Chignik weir was approximately 30 feet below that 

 used in the previous year, where the river is about 455 feet wide and 

 from 2 to 4i/2 feet deep. Construction began on April 25 and was 

 completed on JNIay 25. The first sahnon passed upstream on June 

 6, and counting was continued through June 24, when 104,565 red 

 salmon had been tallied. As a result of heavy rains which began 

 on June 20, the river rose rapidly and the gravel at the bottom was 

 washed away, causing the weir to sag and finally, on the morning of 

 June 25, to break down so that the salmon could pass through. By 

 July 17 the river had dropped 1 foot, and an attempt was then made 

 to repair the weir, but it was unsuccessful. 



The run of red salmon, which reached its peak during the week 

 ending July 1, was light throughout the season. The reported catch 

 of reds was 541,678, and it was estimated that 534,660 escaped to the 

 spawning grounds. The run of chum salmon was the largest since 

 1929, the pink salmon run was good for an off year, and the coho run 

 was fair. Warden Charles Petry was in charge of the Bureau's 

 work at this place. 



CHIN IK CREEK 



A weir was placed in Chinik Creek, Kamishak Bay, on the site 

 formerly used, and from June 28 to July 25, inclusive, 39,222 red 

 salmon were counted. Frank West, stream watchman in the dis- 

 trict, pel formed the weir work under the direction of Capt. H. L. 

 Cole. 



ALITAK BAY 



The cannery station weir on Olga Bay, in the Alitak Bay region, 

 was installed for the purpose of catching predatory trout in the 

 spring and was operated for a number of weeks thereafter in counting 

 the salmon escapement. From May 23 to August 26 there were 

 counted 90,448 red salmon. As this stream normally receives about 

 25 percent of the run into Olga Bay, it is estimated that at least 

 300,000 red salmon entered the Olga Bay tributaries. The total 

 reported catch of red salmon in the district was 168,540. 



Henry B. Looff conducted operations here under the supervision 

 of Warden Howard H. Hungerford. 



SALMON LIFE-HISTORY STUDIES 



Studies of the biology of the Alaska salmon w^ere continued in 1933 

 by the staff of investigators of the Fisheries Biological Station at 

 Seattle, Wash. Two major investigations dealing with the red 

 salmon, at Karluk and Chignik, and one pertaining to the pink 

 salmon in southeastern Alaska were in progress during the year.
