ponds and will be released this fall when conditions of the river and 

 temperature are favorable. 



We desire again to call particular attention to the salmon run in 

 the Sacramento and San Joaquin rivers. Already greatly depleted, 

 it is threatened with extermination, if measures are not taken at once 

 to increase the output of salmon fry from the hatcheries. The con- 

 struction of impassable dams and the diversion of water for irrigatioii 

 is fast cutting off the last remaining spawning beds in the tributary 

 streams of these rivers and this excellent fish is doomed to extermiiia- 

 tion if prompt action is not taken. This department has called atten- 

 tion to this condition for the last four years, but the legislature and 

 the commercial fishermen as well as the general public pay no heed 

 to the recommendations offered and no action to save this fine fish is 

 taken. The Fish and Game Commission is waging an uphill fight 

 when it comes to conservation as the people do not realize the destruc- 

 tion of wild life until it is too late. 



MOUNT SHASTA HATCHERY. 



During the season of 1920 and 1921, the Mount Shasta Ilatcliery has 

 been operated to its fullest capacity, 10,966.000 salmon fry and 

 21,676,800 trout fry being hatched and distributed from this station. 

 The Mount Shasta Hatchery is one of the best equipped stations in 

 the country. The pond system alone furnished 18.000,000 trout eggs 

 during the last biennial period. The^e with the additional eggs
