Technical Bulletin No. 0217: The Effects of Unbleached Kraft Mill Effluents on Salmon

The attached Technical Bulletin is a report on two aspects of our continuing investigation of the influence of pulp and paper mill effluents on aquatic resources at our West Coast Regional Research Center at Oregon State University. The first study, concerned with growth, food consumption and swimming ability of juvenile chinook salmon, was conducted by Erick M. Tokar, Graduate Student, Department of Fisheries and Wildlife, and Eben L. Owens, Research Engineer, National Council of the Paper Industry for Air and Stream Improvement, at the Pacific Cooperative Water Pollution Laboratories, Oregon State University, Corvallis, Oregon. The study received financial support from the National Council and the Northwest Pulp and Paper Association, as well as a research grant from the Office of Water Resources Research, U. S. Department of the Interior.This study parallels in a number of ways one conducted in laboratory simulated streams and reported earlier in National Council Technical Bulletin No. 210. Your attention is therefore directed to the earlier bulletin as well, for a fuller understanding of the experimental objectives and observations. The second study, concerned with the flavor of jack coho salmon, was conducted by Dean L. Shumway, Department of Fisheries and Wildlife, and Lois A. Sather, Department of Food Science and Technology, Oregon State University, Corvallis, Oregon and received financial support from the National Council and the Northwest Pulp and Paper Association.
