ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1929 269 



MORZIIOVOI BAY 



The Morzhovoi weir, on the outlet of the lake at the head of 

 Middle Lagoon, was put in readiness for operation and a watchman 

 was stationed there during the last week of June. The first salmon 

 passed through the weir on July 7, and counting continued through 

 September 5, when the total escapement was 15,974 reds and 45 

 cohos. Assistant Agent L. G. Wingard directed operations at this 

 weir. 



NAKNEK RIVER 



The counting of salmon ascending the Naknek River to the spawn- 

 ing grounds was started in 1929 by the establishment of a weir about 

 26 miles above the marine ways, just below the rapids, where the 

 river is approximately 1,150 feet wide and at high-water stage is 

 from 4 to 10 feet deep. Seven counting gates were provided, each 

 with an opening about 8 inches wide, and one larger gate was built 

 where the channel is deepest to permit the passage of boats through 

 the weir. Construction was begun on June 2 and completed on July 

 2, the work having been considerably delayed because of heavy wind 

 storms and high water. 



A small early run of salmon ascended the river before the counting 

 weir was completed, and there were some fish below the rack after it 

 was submerged on July 31, but the bulk of the run passed upstream 

 in July. It is noted, however, that the early run appears to be 

 gradually increasing, and it was somewhat larger this year than in 

 any previous year. The total count of salmon from July 3 to July 30, 

 both dates inclusive, was made up of 561,916 reds, 1,498 kings, 

 1,044 chums, and 134 pinks. Wm. E. Sullivan, under the direction 

 of Agent Dennis Winn, was in charge of this weir. 



UGASHIK RIVER 



Construction of the weir on the Ugashik River was started on June 

 17 and completed in 10 days. The first salmon passed through on 

 July 1, when 14 reds were counted. The total escapement through 

 August 10 consisted of 147,513 reds, 557 chums, 29 pinks, and 23 

 kings. It was estimated that there were about 1,500 red salmon in 

 the river below the weir at the time it was removed on August 10. 

 They were not bright fish and presumably would spawn in the stream 

 bed below the rack. No fish were reported in the lower river at that 

 time. Henry McFadden, under the supervision of Agent Dennis 

 Winn, carried on operations at this weir. 



SALMON TAGGING 



Continuing the series of tagging experiments that have been 

 conducted in Alaska since 1922 to develop information on the migra- 

 tion routes of individual runs of salmon, the bureau tagged approxi- 

 mately 4,000 salmon in central Alaska during the summer of 1929. 

 Of this number, 1,900 were tagged in Cook Inlet and about 2,100 in 

 Prince William Sound. 



The Cook Inlet operations consisted of seven experiments carried 

 on in four localities — Flat Island, Nubble Point, Cape Starichkof, 

 and Nikishka Bay. Four species of salmon were tagged, approxi-
