TERRITORIAL HATCHERIES. 



The Alaska Territorial Fish Commission carried on salmon cul- 

 ture at Eyak Lake near Cordova and at Auk Lake and Anan Creek 

 in southeast Alaska. At Eyak Lake 3,134,000 red-salmon eggs were 

 trdcen, from wliich 3,078,000 were eyed and planted in the gravel of 

 streams tributary to that lake, there being a loss of 56,000 eggs dur- 

 ing the period of incubation. Spawn taking began in tliis field on 

 July 6 and was discontinued August 1. At Auk Lake 945,000 red- 

 salmon eggs were collected and transferred to the hatchery at 

 Juneau, from which 779,000 fry were produced and distributed in 

 streams of the Juneau district. In addition a shipment of 5,098,936 

 red-salmon eggs was received from the Federal Bureau of Fisheries 

 station at Afognak, from which 4.933.000 fry were hatched. Of this 

 number 2,600,000 were planted in Auk Lake and 400.000 on Menden- 

 hall Bar. 



Tlie commission operated a humpback-salmon collecting station 

 on Anan Creek during July and August and secured a total of 

 250,000 eggs. These were transferred to Juneau in a green state 

 with a loss of approximately 50 per cent. The 121,000 fry that re- 

 sulted were distributed in the Juneau district. 



At the beginning of the year 100.000 coho fingerlings were being 

 held in the Juneau hatchery. These were planted during the summer 

 in streams and lakes tributary to Gastineau Channel and Lynn 

 Canal. 



In addition to its fish-cultural operations the commission continued 

 the work of removing obstructions from salmon streams, thus open- 

 ing larger areas to the spawning fish. Several streams in the Seward 

 and Ketchikan districts were cleared during the year, $3,659.04 being 

 expended in this work. 



EGG COLLECTIONS BY AVASHINGTON STATE FISHERY AUTHORITIES. 



Early in the season the Washington State Fish Commission ap- 

 plied for permission to make collections of humpback-salmon eggs 

 in southeast and central Alaska, stating that approximately half
