Excerpt from Progress in Biological Inquiries, 1929<br/><br/>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.
