year, the old materials being carefully piled on the bank for emer- 

 gency use. Construction was started on May 7 and completed 10 

 days later. The first salmon were tallied on May 19, and counting 

 was continued through October 8, when the total escapement con- 

 sisted of 1,090,511 reds, 0,485 kings, 110,330 pinks, and 5,754 cohos. 

 At the time the weir was removed on October 9 there were still a 

 few reds in the lagoon that had not entered the river because of the 

 very low stage of the water. 



Departmental regulations prohibited commercial fishing for salmon 

 in Karluk waters prior to o'clock antemeridian June 1, and after 

 September 30. However, as the salmon were late in entering the 

 river, commercial fishing was not permitted until June 21. The run 

 continued very light as the season advanced, and further restrictions 

 were necessary. On July 1 seining was stopped on Karluk beaches 

 between Cape Uyak and Cape Karluk, and all commercial fishing 

 was prohibited in the Karluk district from o'clock postmeridian 

 August 2 until o'clock antemeridian September 1. The commercial 

 take of red salmon from the Karluk run was 155,395, indicating that 

 12 per cent of the total run was caught and 88 per cent escaped to 

 the spawning grounds. 



Except during the seaward migration of young red salmon, the 

 capture and destruction of predacious fishes was carried on by means 

 of traps and beach seines, some 13,500 being taken. As usual, 

 some 50,000 red salmon fingerlings were marked for purposes of 

 scientific study. 



Ray S. Wood, under the direction of Warden H. H. Hungerford, 

 was in charge of counting operations at the weir. 



ALITAK BAY 



The weir at the cannery station was constructed on May 9 and 10, 

 and that at the upper station about two weeks later. The counting 

 of salmon at both weirs began on May 24. In addition to these weirs, 

 which have been operated each season for a number of years, and that 

 on Silver Salmon Creek, which was first maintained in 1929, a new 

 weir was installed in the stream that enters Horse Marine Lagoon, at 

 the eastern end of Olga Bay. The Horse Marine Lagoon weir was 

 completed on June 1 and that at Silver Salmon Creek on June 3; 

 the first salmon were counted through the former on July 9 and 

 through the latter on June 25. Traps for the capture of Dolly 

 Varden trout were maintained at all weirs, and seines were also 

 used from time to time in this work, the total take of these predatory 

 enemies of salmon numbering 104,000 during the season. 



As usual, the greater portion of the Olga Bay escapement passed 

 through the upper station weir. Of a total of 286,138 red salmon 

 counted, 259,497 were tallied at the upper station, 9,907 at the cannery 

 station, 3,045 at Silver Salmon Creek, and 13,689 at Horse Marine 

 Lagoon. In addition, 10,320 cohos, 3,813 pinks, and 180 chums were 

 counted through the weirs. The run in Silver Salmon Creek was over 

 considerably earlier than in the other streams. Removal of the weir 

 there was accomplished on September 10, that at the cannery station 

 on September 27, and the other two on September 24. Cohos were 

 still plentiful in the bay the latter part of September, but very few 

 were entering the streams at that time. The total reported catch of 

 red salmon in the Ahtak district was 113,769.
