Clackamas Station, Oregon (Waldo F. Hubbaud, Superintendent). 



The work of this station consists in the propagation of the quiunat 

 salmon. On August 25, 1891, the work of clearing the fislii]ig-grounds 

 and building the traps was begun. Some distance below the rack, 

 which was built at the end of the previoiis year, were two channels, in 

 each of which a trap was placed. Between the rack and the traps all 

 the large rocks were removed from the river, which left a bed of fine 

 gravel where the salmon came to spawn and thence were driven into 

 the traps. A second fishing-place, further down the river, was made. 

 Here the fish were caught by a net and put in pens, where they were 

 kept till stripped of their spawn. 



On September 8 the first eggs were taken from four salmon caught 

 in one of the traps. It soon became evident, however, that but few 

 fish could be caught at the station, owing to the existence, about five 

 miles below, ot a dam across the river which in low water prevented 

 the ascent of the salmon. As a good many fish were seen below this 

 dam a temporary collecting-station was there established September 

 21. A large tent, to serve as a hatchery, was placed on a small island 

 below the dam, from which, by means of a flume, water was led into 

 the hatching troughs. Two siniwu-takers were left at this station, the 

 parent fish being purchased from the fishermen in the viciliity. 



Eggs were obtained daily during October, the total amount gathered 

 being 1,185,000. The number of eggs taken at the regular station 

 during the season, from Sepl ember 8 to October 31, was 851,500. The 

 total take of eggs was 2,03(5,500. The number of salmon spawned at the 

 station was 198, and at the tent 2 17. The average number of eggs to 

 the full-roed fish was about 5,000. Eye-spots began showing in the 

 eggs taken at the temporary hatchery about October 24, when 90,000 

 eggs packed in boxes, on cautou-flaunel trays, were transferred to the 

 station without loss.
