44 REPORT OP BOARD OP PISH AND GAME COMMISSIONERS. 



EXPERIMENTS ON TRUCKEE RIVER. 



Mr. F. A. Shebley and Mr. N. B. Scofield began a series of practical 

 experiments on the Truckee River during the latter part of September, 

 to determine if the refuse that passes into the river from the Crown 

 Pulp and Paper Mill at Floriston is injurious to trout eggs and fry. 

 The eggs and fry are being studied above and below the mill but the 

 experiments have not yet been completed. A careful record is being 

 kept of all the experiments, and so far the results of the experiments 

 have been very conclusive. When the experiments are finished a full 

 report of the results will be sent to your honorable Board. 



RECOMMENDATIONS. 



Besides the suggestions and recommendations that have already 

 been made in this report, there are a few more that I deem it advisable 

 to give at this time. They relate to the inauguration of a sea coast 

 patrol boat, a southern California hatchery, discontinuance of planting 

 eggs taken from the Sacramento River in other rivers, a general increase 

 of hatchery work and a warning concerning the introduction of foreign 

 fish. 



SEA COAST PATROL BOAT. 



On my trips of inspection in the southern coast counties, I inter- 

 viewed a Eumber of the more prominent fishermen, citizens interested 

 in the preservation of the marine fishes, and the deputies in the seaboard 

 counties, and from what I could learn regarding the condition from 

 Monterey south, I am of the opinion that the Commission should have 

 a motor boat for the sea coast patrol ; a seaworthy boat that could stand 

 the rough weather, so that the deputies could visit any of the islands 

 from San Miguel Island south to Coronado Island. I believe that this 

 is a very important measure for your honorable Board to consider, and 

 I respectfully recommend that you give this your early and earnest 

 consideration, so that the necessary recommendation can be made to the 

 legislature for an appropriation to purchase a good seaworthy patrol 

 motor boat to be used in the coast and island patrol. 



SOUTHERN CALIFORNIA HATCHERY. 



In my March report I recommended that the Commission investigate 

 conditions in southern California, with a view to establishing a small 

 hatchery in that end of the State. Pursuant to this recommendation, 

 in company with Mr. E. W. Hunt, I made a trip in October through 

 the southern California coast counties lying south of the Tehachapi 

 Mountains. We examined a number of important sites and made a care- 

 ful study of them to determine which was the best suited for the loca- 

 tion of a hatchery to supply the southern California streams with trout 

 fry. We found the San Antonio canon in Los Angeles County to be 

 the most favorable. At this site there is an abundance of pure water, 

 free from algas, organic matter, or any form of harmful bacteria or 

 other deleterious matter. The site is just above the intake of the 

 Sierra Power Company's pipe line in San Antonio eaiion, on the south
