kofsky had fair numbers of pinks. A good showing of reds was noted 

 at Long John Lagoon and of chums at Pavlof Bay. Good runs of 

 chums and fair runs of pinks entered the streams from Cape Tolstoi 

 to Kupreanof Point, except at Balboa Bay, w^here the escapement was 

 very poor, apparently due to volcanic eruptions in that region. Ache- 

 redin Bay had a large escapement, but in general the spa^^^ling beds 

 of the Shumagin Islands were poorly seeded. A fair escapement of 

 red salmon at Wosnesenski Island was reported, and Sanak Island 

 had good runs of reds and fair numbers of chums and pinks. For the 

 Alaska Peninsula area in general there was a good escapement of reds 

 and chums and a light escapement of pinks and cohos. 



Bristol Bay. — The escapement of red salmon in the Bristol Bay area 

 as a whole was the most satisfactory in several years. The east side 

 of the hsij, especially, had large numbers of fish which were well dis- 

 tributed over the spawning area. The escapement at Nushagak was 

 much better than had been anticipated, although it was estimated as 

 but about 60 per cent of that required for efficient seeding. All other 

 areas of the district were adequately seeded. Reports covering exam- 

 ination of the spawning areas by Agent Dennis Winn and others will 

 be found elsewhere in this publication. 



HATCHERIES 



EXTENT OF OPERATIONS 



The propagation of salmon in Alaska was carried on at two Govern- 

 ment hatcheries (at Afognak and McDonald Lake) and at one privately 

 owned hatchery — that of the Northwestern Fisheries Co. at Hugh 

 Smith Lake.

' Also 32,826 steelhead trout eggs and 2,731,424 Dolly Varden trout eggs were collected, the latter for ship- 

 ment to the States. 



* .A.lso 353,000 pink-salmon eggs were collected. Shipped 3,144,960 eyed red-salmon eggs to Seattle in 

 October for the Oregon Fish Commission. 



AFOGNAK 



The Federal salmon hatchery at Afognak produced and liberated in 

 Litnik Lake and smaller lakes near by 5,553,080 No. 1 red-salmon 

 fingerlings from the 6,347,270 eggs of that species collected in the 

 summer of 1930. The net loss on the take, therefore, was approxi- 

 mately 13 per cent. Of the 13,671,670 pink-salmon eggs collected in 

 August and September, 1930, 10,155,776 v.^ere shipped in the eyed 

 stage to the Department of Fisheries and Game of the State of Wash- 

 ington; from the remainder there were produced 1,145,334 No. 1 

 fingerlings, which were released in Litnik River in April and June, 1931. 



In May there were taken near the outlet of Lake Litnik 32,826 steel- 

 head trout eggs, which were planted in Eagle Creek in June.
