NOTES ON OPERATIONS 



COMMERCIAL SPECIES 



Pacific salmons. — In the Pacific coast field, including Alaska, the 

 main activity is the propagation of salmon, with the object of main- 

 taining the important industry dependent upon the fisheries for these 

 species. In connection with this work during 1932 there was a mod- 

 erate decrease in the output of all the Pacific salmons with the excep- 

 tion of the chum and the steelhead salmons. In certain areas, how- 

 ever, particularly in CaHfornia, where hatcheries are operated at Baird 

 and near-by substations, and on the Columbia River, capacity collec- 

 tions of eggs were made, and a considerable portion of the run was 

 allowed to spawn naturally, due to insufficient room to care for the 

 eggs. In the Puget Sound field, where five stations are operated, one 

 of the most striking features was the damage caused b}^ floods during 

 the early spring. In the Columbia River area salmon flesh to the 

 extent of more than 14 tons was frozen and held in cold storage for 

 the purpose of feeding it to the millions of fish held for rearing to 

 fingerling size. It was reported that at the Yes Bay (Alaska) station 

 one of the best runs of sockeye salmon noted in years was in evidence. 



Various major improvements were made at a number of points, in- 

 cluding a complete rehabilitation of the water supply system for the 

 Clackamas (Oreg.) station, which comprised a new pump and replace- 

 ment of the water-supply line. Over a half-mile length of new water- 

 supply line was also installed at the Little White Salmon (Wash.) sub- 

 station. Salmon propagation at the Snake River (Idaho) substation 

 gave unsatisfactory results but a considerable degree of success 

 attended the handling of rainbow trout. A discussion of the construe-
