Primary emphasis of the research was on (1) salmon (genus Oncorhynchus) in the North Pacific Ocean and the Columbia River Basin and (2) groundfish on the Continental Shelf of the Pacific Northwest. Considerable progress was made toward showing how the distribution of salmon is related to the ocean environment. Biochemical techniques showed promise in pinpointing genetic and geographic differences in stocks of fish. To gather the data needed for managing the salmon stocks, integrated studies were made of ocean growth, mortality, maturation, and effects of gear on salmon. Research in the Columbia River Basin provided new information on how dams and reservoirs affect salmon and steelhead trout (Saimo gairdneri) ; studies were made to measure and to develop ways to counteract the losses of fish. Groundfish research disclosed diff"erences in Pacific hake (Merlucci-us productus) stocks of Puget Sound and the Continental Shelf. Publications and staff of the laboratory are listed. Scientific fishery research of the U.S. Government in the Pacific Northwest was accelerated under the terms of the White Act of 1930. A 3-story research building was completed in 1931 on a 7-acre site at 272.5 Montlake Boulevard East, Seattle, Wash., on Portage Bay south of the University of Washington. A new 4-story laboratory, connected to the "old" building by an auditorium-library, was dedicated in 1965 and provides 65,000 square feet of additional laboratory and oflice space. The Biological Laboratory shares the Montlake research complex with other Bureau of Commercial Fisheries agencies — the Exploratory Fishing and Gear Research Base, Food Science Pioneer Research Laboratory, Marketing Office, and Technology Laboratory. The Biological Laboratory, with some 80 scientists, is the largest research organization in the Bureau. Under Laboratory Director Gerald B. Collins, our scientists conduct intensive research on salmon and groundfish of the eastern Pacific Ocean to accomplish the aims of the Bui'eau — to strengthen the American fishing industry and to conserve the fishery resources. Assistant Director Francis M. Fukuhara directs marine and coastal research on salmon and groundfish; Assistant Director Carl H. Filing supervises fresh-water and estuarine research. Of inestimable value is the Laboratory's close association with representatives of the fishing industry, government officials, educators, engineers, and scientists — locally, nationally, and inter-
