13. Development of a Silver Salmon Brood Stock. 



The silver salmon (Oncorhynchus kisutch) has proven itself to be an effective 

 tool for sport fishery management in the fresh waters of Montana. The future for 

 a supply of eggs from sea-run stock is questionable. As a part of this project it 

 was found that eggs taken from land-locked fish planted from sea-run stocks 

 could be fertilized, hatched, and reared in a hatchery. A brood stock was 

 started from eggs taken from land-locked fish. These fish became ripe for the 

 first time in 1953-54.

14. Phases of the Life History of the Utah Chub in Montana. {FA: F-9-R in part) 



The Utah Chub is native to the Bonneville Basin of Utah and the upper Snake 

 River Drainage. These were introduced into Hebgen Lake, Montana, by minnow 

 fishermen. It is now present in the Missouri Drainage as far downstream as 

 Helena. The Utah chub is a nuisance fish of considerable magnitude. It is felt 

 that a better understanding of this fish may lead to methods of control.
