Another encouraging feature is that so long as these refuges remain 
inviolate it will be practically impossible to exterminate the larger 
game animals. 
Fishculture. 
During the past two years our Department of Fishculture has had in 
operation twelve hatcheries and nine egg-collecting stations. The out- 
put of the hatcheries has been very gratifying. A 16 per cent increase 
in the number of trout fry reared is to be noted, the total output being 
35,058,000. These millions of trout were successfully planted in the 
streams of the state by means of our distribution cars and auto trucks. 
The output of the Mount Shasta Hatchery will compare favorably with | 
that of any trout hatchery in the world. The limit capacity of trout 
fry that can be successfully reared at this hatchery is about ten million. 
In 1916, 9,377,000 trout fry were distributed from this hatchery, and 
in 1917 the total was 9,972,000. 
Experiments started several years ago have proved that the eaten 
trout will do well in lakes in the interior. As a consequence it will be 
safe to plant trout of this variety in the mountain districts and 
increased numbers of this variety will be reared in the future. In 
order to increase the output of Eastern brook trout, arrangements were 
made with the Nevada Fish Commission to operate the Marlette-Carson 
Hatchery. As a result 577,000 additional Eastern brook fry were 
planted in 1916 and 200,000 additional in 1917. For the first time 
golden trout have been propagated. At an ege-collecting station estab- 
lished at Cottonwood Lakes 500,000 golden trout eggs were taken in 
1918. These eggs were successftlly hatched at the Mount Whitney 
Hatchery. 
Although less salmon were hatched during the past biennial period, 
the output of the California hatcheries amounted to 25,701,000. Splen- 
did results have been obtained from the pond system installed. 
Although in the past we have relied largely upon salmon eges furnished 
us by the United States Bureau of Fisheries, we will in the future 
obtain the larger proportion of the eggs ourselves. An egg-collecting 
station has been established at Bryan’s on the Hel River, and next year 
we will take over the Bureau of Fisheries’ Station on the Klamath 
River. 
Shad were propagated for the first time during the spring of 1916, 
when a hatchery was established at Yuba City. A total of 872,000 
shad fry were planted in the Feather River as a result of the season’s 
operations. 
The completion and successful operation of the Mount Whitney 
Hatchery in Inyo County has solved the distribution problem in gouth-
