TECHNOLOGICAL INVESTIGATIONS 



The primary function of the Bureau of Fisheries is to properly 

 conserve the food fishes of the Nation. Conservation should be 

 understood to include more than a simple saving or hoarding of 

 resources. In order that our fisheries may be of greatest value, they 

 must be made to yield the maximum supply of fish food commensurate 

 with their continued productivity. This means that raw materials 

 taken from the sea should be utilized in a manner that will provide 

 the greatest amount of properly prepared food materials to the Nation. 

 The fishing industry is notoriously backward in the adoption of iin- 

 proved methods of preserving and marketing its products, the utili- 

 zation of its by-products, and in so conducting its business as to fur- 

 nish a stable suppl}'^ of products. 



Fisheries technolog}', as practiced by the Bureau of Fisheries, has 

 to do with the improvement of existing and the development of new 

 and better equipment, methods, products, and practices within the 

 different branches of the fishing industry, and with the proper 

 utihzation of its wastes and by-products. The accomplishment of 

 these ends calls for the application of science in many forms, and the 

 carrying out of quite widely diversified research, both as to type and 

 purpose. Kjiowledge of practices thus gained are then presented to 

 the industry and their application thereto urged and directed until 

 they become integral parts of it. 



The fisheries industries offer an almost virgin field for work of this 

 nature, and a large amount of such work must be done before they 

 can be placed in the same class with other industries that supply the 

 Nation with food. Well-directed efforts along these lines may be 

 expected to and do yield large returns. The success now being attained 

 with the results of the bureau's net-preservative and sardine-canning 

 investigations bears out this statement. 



The policy of the bureau is to carry on such technological investi- 

 gations as are possible with the limited funds and personnel available
