NOTES ON OPERATIONS 



COMMERCIAL SPECIES 



Pacific salmon .—The output of chinook, chum, silver, and soekeye 

 salmon from the Pacific coast hatcheries was below that of last year. 

 This was due to the decline in the take of eggs. Humpback salmon 

 were handled for the first time since 1934. At the Clackamas, 

 Oreg., station, and its auxiUaries, more than 20,000,000 chinook sal- 

 mon eggs were collected. The collections at Mill Creek and Battle 

 Creek substations were practically quadrupled over last season. This 

 was ascribed to heavy rains and high water during the entire season, 

 permittmg an unusually heavy run of fish. The acquisition of the 

 Delph Creek rearing station by transfer from the Oregon State Game 

 Department is provmg to be a valuable addition to fish-cultural 

 activities of the Clackamas, Oreg., station. Chinook salmon and 

 brook trout were both reared at this point. The Butte Falls, Oreg., 

 substation collected approximately 2,000,000 chinook salmon, 80,000 

 silver salmon, and 113,000 steelhead trout eggs. Two new residences 

 are under construction at this point. 



The Little Wliite Salmon and Big White Salmon, Wash., sub- 

 stations were largely engaged in the propagation of chinook salmon. 

 At the former station 9,775,000 eggs were collected, while at the 

 latter 8,640,000. The take of eggs at both of these units was below 

 that of last year, correlated, of course, with a reduction in the run of 

 fish. Reestablishment of the Big White Salmon station was carried 

 on under the auspices of the United States Anny EngTiieers, as a part 

 of the Bonneville Dam project. Buildings were moved and ponds 

 rearranged. 



In tlie Puget Sound territory the Birdsview, Wash., station collected 

 6,700,000 salmon and trout eggs and received by transfer 1,280,000 

 eggs. These eggs comprised the five species of Pacific salmon and 

 four varieties of trout. Gratifying results have been attained in 

 establishing new runs of soekeye salmon where fingei'ling fish of this 

 species were liberated during 1934 and 1935. The largest run of 

 humpback salmon in the past 25 years occurred in the Skagit River 

 and its tributaries during the fall of 1937.
