The reader is especially referred to the section in the latter part of 

 this report entitled "Statistical survey procedure" which gives in 

 detail the methods employed in the collection of fishery statistics and 

 other pertinent information. 



TECHNOLOGICAL INVESTIGATIONS 



Some of the food industries of this country during the past 15 

 years have made rapid strides in developing new products and new 

 methods of manufacture and in developing a more orderly plan of 

 m.arketing and merchandising. These developments are no doubt 

 directly traceable to such factors as changes in consumer demand, 

 education of the consumer, shifts in population, occupational changes 

 among our people, and others. Many of these developments have 

 leaned toward the production of prepared and packaged foods of new 

 types, with consequent concentration of trimmings or waste which is 

 available for conversion into valuable byproducts. In turn, methods 

 have been found for converting much of this waste into useful com- 

 modities. These developments have clearly demonstrated the need 

 for technical advancement in the aquatic food industry if it is to keep 

 pace with the other food industries. In order to aid in this connec- 

 tion the Bureau is continuously conducting a series of technological 

 investigations covering problems in the manufacture, preservation, 

 and handling of fishery products. A summary of the accomplish- 

 ments in these fields during the past year appears in the next few 

 pages. For details regarding this work, the reader is referred to 

 published reports and special articles of the various members of the 

 staff, or in case the investigation is not completed, by direct com- 

 munication with the Bureau of Fisheries in Washington. 



LABORATORIES 



During 1934 the Division carried on its technological studies under 

 the direction of J. II . Mannmg, in charge of technological investiga- 

 tions, at its laboratories located in Washington, D. C, Gloucester, 

 Mass., Seattle, Wash., College Park, Md., and at a field laboratory on 

 Kodiak Island, Alaska. In addition, certain cooperative investiga- 

 tions were conducted by our technologists in the chemical laboratory of 

 the State Medical College at Charleston, S. C, the food products 

 laboratory of the Massachusetts State College at Amherst, Mass., the 

 bacteriological and chemical laboratories at George Washington 

 University, Washington, D. C, and the laboratory of the Agricultural 

 Experiment Station, College Park, Md. A resum^ of the facilities 

 and equipment at the laboratories in Washington, D. C, Gloucester, 

 Mass., Seattle, Wash., and Charleston, S. C, is contained in the report 

 of this Division for 1933. Late in 1934, under a cooperative arrange- 

 ment with the University of Maryland, our nutrition laboratory was 

 moved from Washington, D. C, to quarters provided free of charge 

 by the university at College Park, Md. This laboratory is now 

 equipped with all the appliances which were formerly in the nutrition 

 laboratory in Washington, D. C.
