38 tr. S. BUREAU OF FISHEEIES. 



Egg collections of the steelhead trout were made from February 

 24 to May 8. There was a ^"ood run of fish, notwithstanding the 

 somewhat unfavorable climatic conditions prevailing, and 3,673,000 

 eggs were secured. After developing them to the eyed stage nearly 

 2,000,000 were transferred to the Rogue River substation for incuba- 

 tion, and shipments comprising a total of 200,000 were furnished to 

 the State fishery departments of New York, Minnesota, and Penn- 

 sylvania, and to the bureau's Bozeman (Mont.) station. The re- 

 mainder were hatched, with the view of rearing the resulting fish 

 to the fingerling stage for distribution in the parent waters. 



SANDY RIVER (OREG.) SUBSTATION. 



With the view of determining the fisli-cultural value of this field, 

 operations were undertaken late in July at the abandoned State 

 hatchery, located below the hydroelectric dam on the Sandy River, 

 near Marmot, Oreg. A rack was hastily thrown across the river to 

 intercept the fish still running, and chinook-salmon eggs to the num- 

 ber of 1,637.000 were obtained between August 18 and September 10. 

 These Avere held until eyed, the losses being unusually heavy because 

 of an inadequate water supply, and were then transported to the 

 Clackamas station to be hatched. While the work with the chinook 

 salmon was still in progress a heavy run of silver salmon was ob- 

 served, but, as no preparations had been made for work with that 

 species, Qgg collections could not be undertaken, and the substation 

 was closed for the season on October 1. In the month of March an 

 employee was stationed at Sandy River to determine the size of the 

 run of steelheads and black-spotted trout, and incidentally, at little 

 expense, he obtained 634,000 steelhead eggs. 



With the experience gained the advisability of conducting opera- 

 tions at this location is no longer questioned, and preparations for the 

 improvement of the hatchery and the proper handling of the stock 

 will be started next season in due time. 



SALMON (IDAHO) SUBSTATION. 



The importance of the Salmon River region in connection with the 

 valuable commercial fishes of the Columbia River Basin having been 

 recognized from the experience gained in the fish-cultural work of 

 past years and the more recent investigations, it was decided to de- 

 velop fish-cultural operations there and not confine the work to egg 

 collections only. The Salmon River with its tributaries and the 

 beautiful glacial lakes that they drain constitutes a most important 

 natural nursery for salmon arid trout. On account of its rugged 

 topography, inaccessibility, and lack of agricultural land much of 

 this territory, and particularly the portion that is drained by the 

 South Fork and the Middle Fork of Salmon River, lying within the 

 Idaho and Payette National Forests, will probably remain unde- 

 veloped for a long period, though a highway follows through the 

 canyon of the main branch of the Salmon River from Shoup to 

 Stanley, a distance of 150 miles. Because of the splendid spawning 

 areas available, in addition to the advantages mentioned above, it 

 would seem that some measure of protection against the unsports- 

 manlike methods pursued by many, of spearing and otherwise dis-
