At a series of predesignated stations extending from off Northern Vancouver Island to off Unalaska Island, Alaska, experimental and exploratory fish- ing will be conducted to obtain information on the high-seas distribution, abundance, life history, racial composition, etc., of North Pacific salmon in the Gulf of Alaska and adjacent offshore waters. Additional objectives will be to catch salmon on the high seas in condition for tagging and to collect salmon from various localities for studies of racial determination, size composition, age analysis, and other related data. Oceanographic observations in connection with these fishing activities will al- so be made. The primary fishing gear will be nylon gill nets of various mesh sizes design- ed to catch both mature and immature salmon. A series of east-west transects will be run across the Gulf of Alaska with fishing stations at 60-mile intervals. Special attention will be given to an area southeast of Kodiak Island which is report- ed to be rich in plankton. A limited amount of experimental fishing will be done with surface long-line and trolling gear in addition to the gill Scientific personnel from the Service's Branch of Fishery Biology and from the Department of Oceanography, University of Washington, will participate in the re- search. All salmon caught in suitable condition will be tagged and released. Mor- phometric measurements, stomach analyses, blood samples, and other biological data will be obtained. Oceanographic observations, including water samples, tem- peratures, etc., will be taken at each fishing station and at other regular intervals. This cruise is part of the research program approved by the International North Pacific Fisheries Commission. Liaison will be maintained when possible between the John N. Cobb and other research vessels operating in nearby waters. Informa- tion
