NOTES ON OPERATIONS 



COMMERCIAL SPECIES 



Pacific salmon. — Headquarters for the work in both the Pacific 

 Coast States and the Rocky Mountain section were transferred to 

 Seattle, Wash., at the start of the fiscal year. The propagation of 

 the Pacific salmons yielded much better results than during the 

 previous year. A noticeable increase in the two most valuable 

 species, the chinook salmon and the sockeye salmon, was registered. 

 No pmk salmon were propagated and the chum variety was handled 

 in smaller numbers. 



The augmented output of chinook salmon was due to a record run 

 of fish at the Big and Little White Salmon, Wash., substations. Col- 

 lections were made to the full capacity of these establishments and 

 enough fish were available to yield a collection of approximately 

 45,000,000 eggs. It is particularly important to increase the pro- 

 duction of this variety, due to the changes which will occur in the 

 Columbia River following the completion of the Bonneville Dam. 

 In fact, these two stations will be partly flooded when the dam is 

 completed and plans are being made for their relocation at other 

 points where the work can be contmued with the same efficiency 

 and trout may be handled in addition. 



The facilities of the main station at Clackamas, Oreg., were im- 

 proved by the action of the State of Oregon in transferring to the 

 Bureau the hatchery property located at Delph Creek, a few miles 

 away. This will be used to rear trout and salmon during the sum- 

 mer months when the water supply at the station is inadequate. The 

 fish cultural work at Clackamas proceeded along normal lines other- 

 wise. The station is constantly increasing its production of game 

 trout, however. 



In the California field no effort was made to collect eggs at the 

 Baird station due to the uncertain results and the cost involved. A 

 million and a half chinook salmon eggs were transferred for incubation 

 from the Battle Creek substation. Total collections at that point 

 amounted to 8,500,000, approxunating a normal take under existing 

 conditions. At the MiU Creek substation egg collections amounted 

 to 4,500,000. 



In the Olympic Pieninsula the output of sockeye from the Quinault, 

 Wash., station again resumed normal proportions, approximating 

 13,000,000. Some new rearing ponds were constructed by E. C. W.
