ANACONDA 



The silver salmon (Oncor- 

 hynchus kisutch) has become an 



important fish in the manage- 

 ment of certain Montana lakes. 

 The eggs have been obtained 

 from west coastal states, how- 

 ever, hydroelectric and other 

 water developments in the 

 Columbia River system have so 

 lowered the supply of silver 

 salmon that there is doubt 

 whether Montana can continue 



to obtain eggs from these sources. 



Prior to this biennium, silver salmon eggs have been obtained 

 from fish in Georgetown Lake and hatched at the Anaconda station. 

 Fish reared from these eggs have been held at this station and during 

 this biennium eggs were obtained from the resulting mature fish. 

 This is the first time on record that silver salmon eggs have been 

 obtained from brood stock which have spent their entire life cycle 

 in fresh water. 



The Anaconda station is of great importance to the hatchery 

 system in the State, since it is used for collection and distribution 

 of rainbow and cutthroat eggs for a large portion of the other 

 hatcheries in the state. The Georgetown Lake and Willow Creek 

 reservoir spawning stations are operated from Anaconda. 



In addition to the wild eggs taken, the domestic brood stock 

 of early spawning rainbow is maintained at this station. 



All necessary maintenance was carried on at the Anaconda 

 station. ^
