Sockeye Salmon 



Most of the sockeye salmon were tagged from 

 June 15 to July 9. Of the 1,318 sockeye 

 salmon tagged, 84 (6.4 percent) were re- 

 covered (table 3). 



Most returns were from the Kvichak- 

 Naknek system (46.4 percent of the number 



recaptured)' and the Egegik system (15.5 

 percent) (fig. 5). At Cape Lutke, 18 tagged 

 sockeye salmon (21.4 percent of those re- 

 captured) were recovered but only 3 of these 

 had been tagged there. The other 15 tagged 

 fish recovered at Cape Lutke had been tagged 

 at points to the east- -4 from Unimak Bight 

 (10 miles) and 11 from Cape Pankof (45 miles) ; 

 elapsed time between tagging and recapture 

 averaged only 1 day. The small number of 

 recoveries of sockeye salmon tagged at Cape 

 Lutke and later recovered in the same place 

 and the short time between release of tagged 

 fish at Cape Pankof and recapture at Cape 

 Lutke indicate a rapid westerly movement 

 along the south shore of Unimak Island. 

 From the similarity in distribution of re- 

 coveries between the 1961 and the 1922 and 

 1923 laggings (Gilbert, 1923; Gilbert and 

 Rich, 1925), we infer that the Cape Lutke 

 fishery does intercept the westerly migration 

 previously demonstrated. 



The recapture of tagged sockeye salmon 

 indicates only a negligible easterly migration 



' An additional tag fronn a sockeye salmon tagged at 

 Cape Pankof on July 9, 1961, was found on the beach of 

 Iliamna Lake in summer 1963.
