Department or Commerce, 



Bureau of Fisheries, 

 Washington, July 1, 1930. 

 The honorable the Secretary of Commerce. 



Dear Mr. Secretary: I have the honor to submit the following 

 repoit ol" the ojierations of the Bureau of Fisheries during the fiscal 

 year ended June 30, 1930. 



There is much evidence of an intensified interest in the future 

 welfare of our fisheries. Sportsmen's organizations are concentrating 

 their efforts to provide better angling, to overcome the evils of pollu- 

 tion, and to obtain the passage of State and Federal laws which will 

 more adequately conserve this great natural resource. Commercial 

 fishernuMi are taking a greater harvest from the waters than ever 

 befoie, are introducing greatly improved methods, and are revealing 

 a greater interest in the proper conservation of this resource as a 

 sound economic policy. State governments are giving more and 

 more attention to legislation aftecting the fisheries, and State execu- 

 tives are revealing greater interest in the selection of capable adminis- 

 trators in their departments of conservation. The State Department 

 has negotiated with Canada a revised convention for the preservation 

 of the halibut fishery of the North Pacific Ocean and a convention for 

 the preservation and extension of the sockej^e salmon fisheries breeding 

 in the P>aser River system, which now await ratification by the 

 Senate. Greater cooperation is requested from the bureau by other 

 Federal agencies in the heavier stocking of the waterways on public 

 lands with game fish and in working out a sti'eam-stocking policy to 

 insure good fishing to the millions of our people who visit our national 

 parks and forests annually. C\nigress has also revealed a greater 

 interest in fishery problems in the passage of a 5-year construction 

 and maintenance program for the Bureau of P^isheries, an amended 

 black-bass law of much broader power, provision for the study of the 

 probable effect on the fisheries of the proposed power project in 

 PassanuKjuoddy Bay, and by the Senate's action in creating a special 

 connnittee on the wild life resources of the country. 



The iiureau of Fisheries finds a reflection of this intensified interest 

 in the increased demands for fish for stocking waters, for additional 

 fish-cult ui'al facilities, and aid to a greater number of |)rivate organiza- 

 tions interested in the cooperative rearing of fish for stocking local 

 streams. This is also true of the demands for scientific investigations 

 to disclose the need of stronger conservation measures; for studies of 

 every important fishery to reveal its condition and trend; for an 

 expansion of its investigative program with respect to such aqui- 

 cultural i)ursuits as oyster farming, fish farming, and the control and 

 prevention of diseases. Likewise more intelligent interest is being 

 shown in the solution of the i)roblems of the commercial fisheries, 

 improvements in methods of numufacturing and merchandising, in the
