THIRTY-FOURTH BIENNIAL REPORT 17 



the Pisino clam, and a study of Monterey Bay "wluch is being' carried 

 on in cooperation with Stanford Universit}'. 



Six fish bulletins and numerous short articles have been published 

 by members of the laboratory staff during the biennium. 



FISH EXCHANGE 



According to the requirements set forth in Chapter 825, Statutes 

 of 1933, the Fish Exchange unit of the Bureau of Commercial Fisheries 

 was abolished on June 30, 1936. During the year 1934-35 this unit 

 carried on an extensive publicity campaign for the purpose of increas- 

 ing the consumption of fresh fish. As a part of this program exhibits 

 were shown at the state and eount}^ fairs, cooking demonstrations were 

 held and recipe books were distributed to houscAvives. In addition, 

 over 1200 i-etail dealers were contacted and given advice relative to 

 the iini)r()vement of fresh fish marketing methods. 



BUREAU OF HYDRAULICS 



This bureau was reestablished during 1935 after a period of 

 inactivity which was the result of the passage of a bill requiring the 

 Division to pay one-half of the cost of screening diversions which are 

 destructive to game fish. The personnel of the bureau has been engaged 

 in preparing plans and specifications for fish screens which will be 

 constructed as funds are made available. Plans have been formulated 

 for the screening of some 250 diversions in the Klamath River drainage 

 basin alone. 



The reinstallation of the fishway at the Benbow Dam on the South 

 Fork of the Eel River and the careful testing of the Burkey electric 

 fish stop have been supervised by engineers connected with this bureau. 

 In addition, the routine inspection of existing fish screens and ladder.s 

 is being carried on as part of the every day work of the hydraulic staff. 



BUREAU OF LICENSES 



The Division is supported entirely by the sale of licenses, the 

 income from privilege taxes and fines for the violation of game laws, 

 and it is therefore gratifying to note that this bureau reports a sub- 

 stantial increase in the income of the Division during the biennium just 

 ended. A comparative analysis of the income of the Division during 

 the past four bienniums is an interesting addition to the usual financial 

 statement. 



The adoption of a new style of license identification button became 

 effective in 1935 and, during that same year, a blank on which each 

 sportsman was asked to list the amount of fish or game taken during 

 the preceding year was made a part of the hunting and fishing license 

 applications. Boats, catering to fishermen for profit, were licensed 

 during 1935 and the section of the Fish and Game Code which requires 

 a license to angle for game fish in the ocean was enforced for the first 

 time during 1936. 



To facilitate the sale of licenses the adoption of a uniform system 

 of license distribution has been urged. Licenses are distributed to 

 vendors at the present time by three separate and distinct methods.
