Table 6. — Elapsed time between tagging of chum 

 salmon off south shore of Unimak Island and 

 southwestern shore of Alaska Peninsula and 

 recapture at principal recovery areas, 1961 



Too few pink salmon were tagged and re- 

 covered to warrant any conclusions, but the 

 pattern of recoveries was similar to 1958 

 when pink salmon tagged in June migrated 

 west, and those tagged in July spawned in 

 local streams (Thorsteinson, 1959). 



Coho and King Salmon 



Not one of the 4 coho or 20 king salmon 

 tagged was recaptured. Eighteen of the king 

 salmon were immature and had lengths of 

 350-575 mm. All immature king salmon had 

 spent only one winter at sea, and most were 

 tagged near Cape Pankof in early July. 



SUMMARY 



Table 7. --Age of chum salmon tagged off south 

 shore of Unimak Island and southwestern shore 

 of Alaska Peninsula, June 15 to July 14, 1961 



from widely separate spawning grounds were 

 passing through the tagging area (fig. 7). 



During June 15-28 inclusive, 145 Pink 

 salmon were tagged; only 4 were recaptured. 

 The recaptured fish were taken at points 

 west of the tagging sites --two at Cape Lutke 

 (tagged at Unimak Bight and Cape Pankof); 

 one at Ikatan Bay (tagged near Deer Island); 

 and one near Pakachak River, East Kam- 

 chatka, U.S.S.R. (tagged in Unimak Bight). 



Although most pink salmon tagged during 

 July were recaptured near the tagging sites, 

 two migrated in an easterly direction. One 

 was tagged July 8 at Cape Pankof and re- 

 captured in the Buskin River, Kodiak 

 Island, and the other was tagged July 14 in 

 Morzhovoi Bay and recaptured in Geographic 

 Harbor on the Alaska Peninsula north of 

 Kodiak Island. 



Salmon tagging off the south shore of 

 Unimak Island and the southwestern shore 

 of the Alaska Peninsula from mid-June to 

 mid- July of 1961 demonstrated that sockeye 

 and chum salmon move westerly and then 

 northeasterly into the Bering Sea. Lack of 

 movement eastward from Cape Lutke indi- 

 cates that this is the last point at which 

 salmon migrating into the Bering Sea are 

 taken south of the Peninsula. 



Of 1,318 sockeye salmon tagged, 84 (6.4 

 percent) were recaptured; 63 percent of the 

 number recaptured were taken in Bristol 

 Bay. The average rate of travel from the 

 tagging area to the Kvichak-Naknek and 

 Egegik areas was 31. 3t 6.2 nniles per day; 

 elapsed time between tagging and recapture 

 was 11-20 days, with a mean of 14.9. More 

 than 70 percent of the tagged sockeye salmon 

 were 5-year-olds. 



Of 996 chum salmon tagged, 60(6.0 percent) 

 were recaptured. Chum salmon exhibited a 

 broad pattern of dispersion, with most re- 

 captures being made from points along the 

 north side of the Alaska Peninsula, Bristol 

 Bay, and the Bering Sea coast as far north 

 as the Koyuk River on Norton Sound. One 

 tagged chum salmon was recovered from 

 a Japanese river and another from Kodiak 

 Island. Nearly 70 percent of the tagged chum 

 salmon were 4-year-olds. 



Of 247 pink salmon tagged, 13 (5.3 percent) 

 were recaptured. Too few pink salmon were 

 tagged and recovered to warrant definite con- 

 clusions, but the results indicate an inter- 

 mingling of widely separated stocks as 

 evidenced by one recapture from Kodial^ 

 Island and another in the Pakachak River, 

 Kamchatka, U.S.S.R.
