> U. S. BUREAU OF FISHERIES 
FOREWORD 
This report constitutes a summary of the activities of the Division 
of Fishery Industries as well as an annual review of fishery statistics. 
As its name indicates, this Division of the Bureau is concerned with 
the activities and welfare of the commercial fishery and fishery in- 
dustries, the trade in fishery products, and the fish canning and pre- 
serving industries. Its functions include the collection and publi- 
cation of fishery statistics, the conducting of market surveys, the 
prosecution of research designed to solve the technical problems of 
the industry, and the dissemination of authoritative and practical 
information to the fishery industries and the public. Results of 
technological investigations and marketing studies are published in 
separate documents as each project is completed. The information 
obtained from statistical surveys 1s published in part 2 of this report, 
which includes all the detailed statistical information that has become 
avaliable since the issuance of the previous report,” together with such 
summarized statements and interpretations of the statistics as are 
deemed significant and useful. In the preparation of this report, 
members of the Division’s staff have taken part and their assistance 
is appreciatively acknowledged. 
Part I. OPERATIONS OF THE DIVISION 
COOPERATION WITH OTHER FEDERAL: AGENCIES 
As in 1935, various members of the Division’s technological, eco- 
nomic, and statistical staff assisted other Federal agencies where the 
work and studies of such agencies required information or advice 
concerning the fishery industries. 
During the past year, our technologists engaged in a cooperative 
investigation with the Bureau of Chemistry and Soils and the Food 
and Drug Administration of the United States Department of Agri- 
culture for the development of standards for halibut-liver oil essential 
in the administration of the Federal Food and Drug Act and for other 
purposes. This cooperative project will be described in detail else- 
where in this report. In addition, various members of our technolog- 
ical staff, both in our Washington, D. C., laboratories and in our field 
laboratories, cooperated with the scientists of other Federal Govern- 
ment organizations wherever helpful information of mutual interest 
could be exchanged and whenever cooperative assistance could be 
extended. 
For a few months in the summer of 1936, Dr. Francis P. Griffiths, 
of our technological staff, conducted some practical studies in the 
freezing of oysters in the Seattle laboratory of the Bureau of Chem- 
istry and Soils, United States Department of Agriculture. 
The National Bureau of Standards also cooperated with our tech- 
nological staff in the development of net measuring devices for exper- 
imental use in the Great Lakes’ fisheries. 
Our technologists, in the Bureau’s Washington laboratories, gave 
courses in canning fishery products to State Extension Service 
workers at the request of the State Extension Service, of the United 
States Department of Agriculture. 
Cooperation was had with the Bureau of Foreign and Domestic 
Commerce in obtaining data on the extent of the cooperative move- 
an Fishery Industries of the United States, 1935, by R. H. Fiedler: Appendix II to the Report of the 
U.S. Commissioner of Fisheries for 1936, pp. 73-348.
