PROPAGATIOX AND DISTRIBUTION OF FOOD FISHES, 193 3 473 



The Si)earlish (S.Dak.) station was rendered more efficient by the 

 construction of a small auxiliary or substation on leased property 

 several miles from the hatchery. This was necessitated by recurrent 

 failure of the luain spi-ing water supi)ly in the hatchery during the 

 winter months. A suitable buildino; was constructed and the eggs 

 were incubated there for transfer to the main station for rearing 

 when the water supply returned to normal. The output of this sta- 

 tion was increased thereby, both as to numbers and size. 



There was placed in operation during the year a new station in 

 southern Idaho located near the towai of llagernum. The hatchery 

 was constructed during the winter months and a superintendent's 

 dwelling was completed at the close of the fiscal year. Several 

 buildings already on the pro])erty were remodeled for use as dwellings 

 and other purposes. The water supply was developed and consider- 

 able improvement to the grounds in general was effected. The 

 station was stocked with eggs of rainbow and steelhead trout during 

 the spring months, the latter having been obtained from collections 

 at Williams Lake, Idaho. It was evident that owing to the relatively 

 high temperature of the w^ater a splendid rate of grow^th will be 

 attained with the fish reared at this station. The Salmon (Idaho) 

 station formerlj'^ operated for the propagation of commercial salmon 

 will be discontinued. 



The Dexter (N.Mex.) station, one of the two hatcheries for warm- 

 water fish in the Western territory was very successul. A satis- 

 factory output of fish, particularly bass, was attained, the total 

 production being slightly over 400,000. Minor construction work 

 in the nature of completion of projects already under way was car- 

 ried on. These comprised the completion of the superintendent's 

 residence and pump house and some additions and im})rovements 

 to the pond system. Two wells were also drilled for the purpose 

 of increasing the water supply. 



The Bozeman (Mont.) station was connected up to utilize ele*-- 

 tricity for power and lights. The station distributed over 16,500,000 

 eggs and fingerling fish within its own territory reciuiring 26 trips 

 by the fish car and 84 truck trips with at least 10 carloads of fish 

 remaining on hand at the close of the year. 



The two substations located in the Madison Valley at Ennis and 

 Blaine Springs w^ere also successful in their operations. The former 

 w^as responsible for a collection of over 23,000,000 Loch Leven trout 

 eggs and less than 1,000,000 rainbow trout eggs. At the new Blaine 

 Springs substation the development work was the main activity, 

 a 48-trough hatchery having been practically completed and a resi- 

 dence and garage being virtually ready for occupancy. Work was 

 started on other buildings and the construction of 5 rearing ponds 

 was also taken up. 



At the Miles City auxiliary operated for the production of bass and 

 other warm-water pond fish, the fall distribution was (juite satisfactory. 

 However, owing to the severe winter, there was a heavy loss of adult 

 brood bass which necessitated replacement with 400 specimens in 

 June. Arrangements have been made to secure the use of a leased 

 pond better adapted for wintering the brood stock. 



The season at Glacier Park substation was, as a whole, successful. 

 Attempts to take brook trout eggs within the Park were not particu- 

 larly gratifying, however, since only a limited number were obtained.
