FY 1986 was the eighth year of a study to determine the distribution, contribution, and value of artificially propagated fall chinook on the Columbia River. Tagging of hatchery fall chinook was completed in FY81. Sampling of sport and commercial marine fisheries from Alaska through California, Columbia River fisheries, and Columbia River hatcheries and adjacent streams occurred in 1986 as planned. Catches and returns of one brood year tagged for this study (1981) could have occurred in 1986. Returns of fall chinook to Columbia River facilities as of December 1, 1986 are 108,154. This return is already the fourth largest of the past seven years. Several facilities (Cowlitz, Grays River, and Washougal) are having the greatest returns since inception of the study. However, Spring Creek and Lewis River hatcheries are having the smallest return. Estimated Catches of coded wire tagged salmonids are available through 1984 for all fisheries except Alaska in 1981 and Washington in 1984. Catch proportions by fishery for the 1978 brood are .01, .39, .34, .07, 0, and .19 for the Alaska, Canada, Washington, Oregon, California, and Columbia River fisheries respectively. Catch proportions for the 1979 brood are similar to those for the 1978 brood (.03, .33, .37, .05, .01, and . 21) for the same fisheries respectively. The proportion of recoveries for the four age groups of 1978-brood fish caught are .07, .69, .23, .01 for the two-through five-year-old chinook respectively.
