site for the collection of blaclc-spotted-troiit eggs. A promising field 

 was located, but as no funds were available for the purpose it was 

 impossible to do an3'thing toward its development during the year. 



SPEARFISH (S. DAK.) STATION 



[D. C. Booth, Superintendent] 



Fish-cultural activities at this station were chiefly concerned in the 

 propagation and distribution of the brook, Loch Leven, and rainbow 

 trouts, and the steelhead salmon, the aggregate output of fish of 

 these species for the year amounting in round numbers to 1,460,000. 

 Aside from the work prosecuted at the main station and its Sand Creek 

 auxiliary, located near Beulah, Wyo., the Spearfish station assisted 

 in the black-spotted-trout operations in the Yellowstone Park by 

 furnishing the services of two of its regular personnel during the egg- 

 collecting and eying period in that field. Some work was also accom- 

 plished in the way of pond construction, and, to overcome a con- 

 siderable wastage from the new concrete storage reservoir, a concrete 

 bottom was laid over a large portion of its area. 



Approximately 180,000 brook and Loch Leven trout eggs were 

 collected during the fall from the station brood stock, and 110,500 

 additional wild eggs of these species were secured in the Sand Creek 

 field. This stream constitutes the only available source of supply 

 in the region for eggs from wild trout, and were it not for the fact 

 that it is being heavily fished every year by tourists and automobile 

 parties it could soon be built up to the point where it would form a 

 valuable adjunct to the work of the Spearfish station. This stock 

 was increased by the transfer of 375,000 brook-trout eggs from the 

 Springville (Utah) station and 1,005,000 Loch Leven trout eggs from 

 the Madison Valley (Mont.) field station. 



Between January 29 and March 20 the brood rainbow trout carried 

 in the station ponds yielded approximately 56,000 eggs, and later in 

 the spring a consignment of aoout 55,000 steelhead eggs was for- 

 warded to the station from a hatchery operated by the Oregon Fish 

 Commission. Aside from the distributions made during the year, 

 considerable numbers of young trout of the various species handled 

 were reserved to supplement the station brood stock. 



SPRINGVILLE (UTAH) STATION 

 [Claudius Wallich, Superintendent] 



In pursuance of an agreement entered into with the fisheries author- 

 ities of Utah, an employee of the bureau's Springville station was 

 detailed during October to make collections of brook-trout eggs at Fish 

 Lake in conjunction with employees of the State. This work extended 

 from October 18 to November 25, and during its progress approximately 

 7,000,000 eggs of good quality wore secured, of which 2,500,000 were 

 allotted as the bureau's share. The spawning period could hardly be 

 said to have closed when operations ceased, but the lateness of the 

 season made it appear advisable to discontinue the work and transfer 

 the collections to the home station before the roads were made im- 

 passable by snow. The ^reat abundance of fingerling trout noted all 

 along the shores of the lake in the course of spawn-taking furnishes 



food evidence that the supply of brook trout in this body of water is 

 eing well maintained.
