NOTES ON OPERATIONS 



COMMERCIAL SPECIES 



Pacific salmons. — The work of the hatcheries propagating the com- 

 mercial salmons of the Pacific coast yielded an increased output for 

 two species only — the chum salmon and the important sockeye 

 salmon. A number of these stations handled game trout in addition 

 to the main work with the salmons. In Alaska the Afognak station 

 experienced an average season and special attention was given to 

 improving conditions in Letnik Lake, in which the larger proportion of 

 the output of the station is planted. However, this station was 

 closed at the end of the year, owing to economy requirements and 

 some question as to the value of its operations. At Yes Bay, Alaska, 

 successful results were experienced during the fall of 1932 in the 

 feeding and rearing of sockej^e salmon fingerlings. Some 19,000,000 

 of these were reared and at least 4,000,000 were released at a length 

 of 4 inches. An attempt to follow^ the same procedure during the 

 spring and summer of 1933 was seriously interfered with by the 

 outbreak of an epidemic, which caused a heavy loss among the fry 

 and fingerlings. It w^as not possible to determine the cause or the 

 most effective treatment for this trouble. A number of brook trout 

 hatched and reared at the station was distributed in certain lakes in 

 the vicinity by airplane. 



In the California field the most striking development was a very 

 sharp decline in the take of chinook salmon eggs, the total collections 

 amounting to only a small fraction of the previous year. A special 

 appropriation was available for improvement of the stations in this 

 territory and was expended largely in remodeling the superintendent's 

 residence at Baird and in the development of a deep well and pumping 

 system for improving the water supply at Mill Creek. Other improve- 

 ments of a minor nature were also accomplished with these funds. In 

 the Columbia River section the main station at Clackamas enjoyed 

 a normal season with both salmon and trout. The collection of 

 salmon eggs, chiefly of the chinook variety, exceeded those of 

 last year by some 9,000,000. Water supply pipe to the extent of 

 400 feet was laid at the Clackamas station. The Little White Salmon 

 (Wash.) substation froze and stored 27 tons of spawned-out salmon 

 for use in feeding the fingerling fish held at this point and at the Big 

 White Salmon substation. At Butte Falls, Oreg., a new substation,
