*J4 FISH AND GAME COAIMISSION 



versify participating, lias completed four years of active work. Some 

 18 imhlislied ]iai)ers relating to various i)hases of the investigation have 

 ajjpeared and otliers are in preparation. Some recommendations, the 

 results of careful tests, have already been accepted and put into prac- 

 tice. Ill li»:!4 an allotment of $20,()00 to the United States Bureau of 

 Fisheries from the Public Works Administration permitted Dr. P. R. 

 Xeedham and i\Ir. A. C. Taft of the cooperative investigation to make 

 an extensive stream and lake survey in the state. The work was mostly 

 confined 1(> waters Avitliiii llic Klamath, Sequoia, Inyo and Plumas 

 national loi-ests. TIh' results and recommendations embodied in 

 rcpoils arc now available. The principal activities of the trout inves- 

 tigation have centered about Scott and Waddell Creeks in Santa 

 Cruz County, at Beaver and Fall Creeks tributary to Klamath River, 

 and at Hot Creek ponds in Owens Valley. From these points it has of 

 necessity spread to other localities which offered particular opportuni- 

 ties. The stream studies have much to do with the migratory habits 

 and other features of the life history of rainbow trout, while the work 

 at Hot Ci-eek concerns itself largely with selected brood stocks, the pro- 

 Lluction of eggs, studies in growth, proper diets, hatchery procedure, etc. 

 The bureau has attempted in so far as possible to conduct its work 

 on scientific principles and base its procedure on established facts. 

 Suggestive and constructive criticism have been alike received an4 

 carefully considered. And finally it has attempted to maintain a spirit 

 of friendly cooperation with sportsmen and others interested in the 

 conservation of game fishes and the maintenance of sport fishing.
