Description: The contribution of hatchery produced chinook salmon Oncorhynchus tshawytscha to the Ninilchik River sport harvest was estimated from 23 May to 22 June 1992. A roving creel survey two-stage sample design was used to estimate total effort, catch and harvest. Harvested chinook salmon were examined for adipose finclips to recover coded wire tags. A total of 12,606 salmon were caught with a total effort of 60,246 angler hours. An estimated 4,896 chinook salmon were harvested, with 2,789 estimated to be hatchery produced, for a hatchery contribution rate of 57%. Although total harvest was similar to 1991, hatchery contribution declined 26%. Poor weather and poor water clarity prevented estimation of escapement.
