obtained from trout planted at different ages, of different strains, given differ- 

 ent hatchery care, and liberated in different manners.

8. Rush Creek Trout Management Study. (FA: F-8-R in part) 



This is a continuation of a complete creel census made at this stream since 

 1947. Until 1953, only rainbow were planted, with special emphasis on the sur- 

 vival to the angler of catchable plants. Since 1953, only brown trout have been 

 planted, and the objective will be to find out if it is possible to produce good brown 

 trout fishing for the average trout fisherman. 



Rush Creek, Mono County; began 1947, indefinite; $10,000; J. H. Wales, 

 Leader; reports available.

9. Striped Bass Study. 



The striped bass study is providing the information needed for management 

 of the species. Emphasis during 1953 was placed on winding up a prolonged 

 series of tagging experiments aimed primarily at determining the rate of har- 

 vest, and secondarily at improving tagging techniques. A second phase of the 

 work was the annual survey of the abundance of fry during July. California's 

 striped bass fishery supports an estimated 2, 000, 000 angling days a year, with 

 a total catch of about 1, 500, 000 fish. 



Central California; began March 1946, indefinite; $15,000; reports available.

10. Pit 4 Fish Study. 



The aim is to determine the release of water necessary to adequately main- 

 tain trout in the section of the river to be dewatered when the Pit 4 Power Plant 

 goes into operation in 1955. Electrofishing is being used for population sampling.

11. Experimental Backcountry Fish Management. (FA: F-3-R) 



The objectives of the project are to evaluate the success of past and cur- 

 rent management policies in backcountry waters and make any necessary changes; 

 to determine new or improved management procedures through experimentation; 

 and to evaluate rapid survey or inventory methods used throughout the State. 

 Field operations include examination of stream improvement devices previously 

 installed, possibility of reclaiming a drainage for golden trout, results of fish 

 population control using chemicals, and competition between introduced species. 



Mountainous areas of the Sierra Nevada; began April 1952, to close June 1954; 

 $12, 000; Joseph H. Wales, Leader.

 ment, 106 South Main Street, Bishop, Calif. 



12. Investigation of Disease and Nutrition Problems in California Freshwater Fishes. 



This project is concerned chiefly with disease and nutrition in trout hatch- 

 eries, but related problems in trout and diseases of other freshwater fishes are 

 studied as occasion demands. Current studies are being made of the blood 

 flagellate Cryptobia , the trout myxosporidian, Ceratomyxa , of the microscopic 

 appearance of normal trout tissues, and of hypnotic and anesthetic drugs useful 

 in the transportation of trout.
