SOME NEEDS OF THE FISHERIES SERVICE. 



The Commissioner renews his previous recommendations for a 

 modern building with ample laboratory facilities for the Washington 

 headquarters combined with an aquarium for experimental and 

 observational work in fish breeding, fish feeding, and fish pathology. 

 The aquarium should be adapted for public education and should be 

 recognized as a national institution. The need for and benefits to be 

 derived from such a building are fully set forth in the Secretary's 

 communication to the Speaker of the House of Representatives on 

 April 2, 1917, printed as House Document No. 117, Sixty-fifth 

 Congress, first session. 



In order more adequately to perform the duties devolving on the 

 Bureau, more particularly those that have received an added impor- 

 tance because of the national crisis that necessitates increased output 

 of food and industrial materials, there is urgent need for additional 

 personnel and facilities for practical and immediately productive 

 work in furtherance of the activities hereinbefore referred to, in 

 behalf of the exploitation of neglected aquatic resources, the methods 

 of preservation best adapted to the various products and com- 

 munities, and the prevention of waste in all branches of the fisheries. 

 Items have been included in the estimates of appropriations for the 

 next fiscal year that will meet some of the Bureau's needs in respect 

 to these matters. 



Respectfully submitted. 



H. M. Smith, 

 Commissioner of Fisheries. 



To Hon. William C. Redfield, 



Secretary of Commerce.
