Excerpt from Progress in Biological Inquiries, 1929 Corresponding to these direct studies of supply on the Atlantic coast are the investigations of the great salmon fisheries of Alaska. Here scientific studies are providing information that is rapidly bringing this important source of food within complete control. This promises the ultimate restoration of former abundance and assures the perpetuation of the supply. Of less direct application, but of equal importance to an under standing of the fisheries, are such studies as the tracing of the course of development from egg to adult in these same species of food fishes and in the many related or competing species preying upon commercial forms or furnishing their food. Of still more remote application, but of even more fundamental importance, is the understanding of those factors in the environment that determine the fate of the myriads of fish eggs deposited in the ocean waters each season. Oceanographical studies recently undertaken dealing with the currents, salinities, temperatures, and other physical and chemical phenomena of the ocean waters, as well as the teeming invertebrate life therein contained, all bear ultimately upon fishery problems and may hold the key to the final understanding and control of variations in the fish supply.

Excerpt from Progress in Biological Inquiries, 1935 To many people, perhaps even to most, it implies some form of prohibition. To some it means prohibiting all people from fishing, so that all fish may live their lives in the ocean and in the streams forever unmolested; to others, it means prohibiting only other people from fishing, so that they themselves can enjoy exclusive right to pursue their piscatorial pleasures without competition. In the face of such confusion, then, what does the Bureau of Fish eries mean by conservation? It means precisely what a business organization does when it refers to a conservative financial policy. In other words, it is the practice of getting for the most people the greatest value from resources without impairing the capital - living off the income without cutting into the principal.

Excerpt from Progress in Biological Inquiries, 1928: Including Extracts From the Proceedings of the Divisional Conference, January 2 to 5, 1929 The demands for investigations in all sections Of the country continue to exceed the facilities of the bureau, and it is therefore necessary that the coherent program that has been developing for many years be followed with scrupulous care. The three main phases of this program, comprising investigations pertaining to conservation of the commercial fisheries, studies Of aquiculture or the propagation and cultivation of fresh-water fishes, and the development of Shell fish culture, by no means cover the entire field Of fishery research. Well-conceived plans have been made, however, and presented to Congress to extend investigations in these respective fields during the next 5 years to all of the major fisheries of the country and to the important areas in the interior.
