404 U. S. BUREAU OF FISHERIES 



During the fiscal year the Quilcene and Diickabush (Wash.) stations 

 were transferred to the jurisdiction of the Quinault station. As usual 

 these two establishments concentrated on the propagation of chum 

 salmon, eggs of which are available in large num.bers. However, 

 other species of salmon, including silvers, humpbacks, steelheads, 

 chinooks, and eastern brook trout were also handled. 



At the Birdsview (Wash.) station operations other than of a fish- 

 cultural and routine nature consisted of the installation of a concrete 

 floor in the hatchery, the diversion of Grandy Creek to the Skagit 

 River in order to avoid the possibility of flooding the station grounds, 

 and the partial completion of an additional cottage for residence 

 purposes. Experiments in the marking of sockeye salmon fingerlings 

 for securing life history information w^ere continued. 



The Baker Lake (Wash.) substation received only a limited number 

 of salmon eggs owing to exceptionally poor runs. Over one-half 

 miUion trout eggs of the four species were shipped in with the object 

 of concentrating on the propagation of trout at this point in the future. 

 The new road giving access to this hatchery was completed during 

 the year. 



The Mount Rainier substation incubated a total of 1,000,000 trout 

 eggs for the production of fish to be used in stocking waters of the 

 national park. Throughout the year considerable trouble was ex- 

 perienced with various diseases. 



In the California field various improvements were made to the 

 Baird hatchery and substations through C. W. A. allotments. The 

 fish cultural activities were substantially the same as in the previous 

 year. 



GREAT LAKES SPECIES 



The output of the commercial forms of the Great Lakes was greatly 

 reduced with the exception of pike perch. The two Michigan sub- 

 stations, auxiliaries of the North ville (Mich.) station, were closed 

 early in the fiscal year and achieved no output except several hundred 

 thousand lake trout which were being reared by the jUpena (Mich.) 

 substation. These were planted early in the year. 



The field of operations of the Duluth (Minn.) station was greatly 

 restricted owing to the fact that no fishing was allowed during the 

 closed season for the purpose of taking whitefish or lake trout eggs. 

 A few days fishing after the closed season was ended permitted the 

 collection of 1,500,000 lake trout eggs. Under the same conditions 

 approximately 500,000 whitefish eggs were obtained. Eggs of game 

 trout were incubated and distributed from this point. Cooperative 

 arrangements were effected with the Minnesota Fish and Game De- 

 partment to handle the collection of pike-perch eggs in the spring, 

 but the run was light, yielding only approximately 7,000,000 eggs. 



At the Put in Bay (Ohio) station the sudden advent of cold weather 

 resulted in the cessation of fishing for whitefish before it was possible 

 to secure a large number of eggs, so that only 1 1 ,500,000 were obtained. 

 However, the spring collection of pike-perch eggs was the largest 

 since the station has been in operation. The collections of this spe- 

 cies amounted to 830,000,000, of which over 500,000,000 were incu- 

 bated at the Ohio State hatchery, the balance being handled at the 

 Bureau's station. This hatchery was operated under cooperative
