PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1922. 61 



GLACIER NATIONAL PABK (MONT.) SUBSTATION. 



The work of this small hatchery was addressed to the incubation 

 of rainbow-trout eggs received from the Meadow Creek collections, 

 black-spotted-trout eggs from the Yellowstone National Park and 

 the State of Montana, and steelhead eggs from Applegate Creek, 

 Oreg. The records indicate a distribution of 168,000 black-spotted 

 trout, 250,000 rainbow trout, and 48,000 brook trout, with approxi- 

 mately 160,000 fingerling fish on hand at the end of the year. The 

 bureau is indebted to the State of Montana for the brook-trout 

 fingerlings appearing in the above record, and to this number may 

 rightfully be added the 30,000 fingerlings of this species mentioned 

 as having been placed in Kootenai River and Cameron Lakes. 



In recent 3'ears the pelican has been much discussed in connection 

 with the problem of fish culture and conservation in certain sections 

 of the territory in this region, particularly as regards the Yellow- 

 stone National Park and the Madison Valley, in Montana. This 

 bird, protected by law, it is claimed by many who are apparently in 

 a position to know, constitutes one of the most important agencies 

 in the destruction of the game fishes, and the evidence produced in 

 support of this statement is of a convincing nature. 



In order to obtain more authoritative knowledge on this important 

 subject an investigator, working under the direction of the division 

 of scientific inquiry, was employed near the close of the fiscal year 

 to investigate the habits of tlie pelican in Yellowstone National Park. 



LEADVILLE (COLO.) STATION AND SUBSTATION.

 LEADVILLE (COLO.) STATION. 



During the year the rearing capacity of the Leadville station was 

 increased by repairing and connecting with the water supply the 16 

 cement ponds in front of the hatchery building. Additional troughs 

 were also placed in the hatchery. 



The brook trout is the important species propagated at this sta- 

 tion, and excellent results attended the efforts along this line during 

 the fiscal year 1922. The eggs handled are obtained almost exclu- 

 sively from privately owned lakes, where, under agreement with the 

 owners, the bureau's fish-culturists annually make egg collections 

 from spawning trout. The eggs thus obtained are all taken to the 

 Leadville hatchery, where a predetermined percentage of the total 

 collections from each point of eyed eggs, fry, or fingerling fish are 

 held subject to the owner's disposal. During the fiscal year 1922 col- 

 lections were made from seven Colorado lakes, as follows : 



Turquoise 1 , 3, 027, 200 



Enselbrecht 2, 108,700 



Carroll 235,500 



Northfield 49, 900

Musgrove 587, 600 



Evergreen 96, 500
