The Campbell/Quinsam River system was surveyed from 1975-76 to 1979-80 to assess the effects of steelhead production from the Quinsam Hatchery on the winter steelhead fishery and to compare estimates obtained by the on-site creel survey with those calculated by the annual mail survey (Steelhead Harvest Analysis). Angler use among the most intense in the province, was consistently higher on the Campbell River but tended to decrease as use increased on the Quinsam River. An increase in angler use of the Quinsam River occurred after 1977-78 when the first adult hatchery steelhead entered the fishery. This numerical response by anglers implies general acceptance after 1977-78 but the estimated increase may not necessarily reflect real changes in either of the two parameters. Possible confounding effects are discussed. Estimates of angler-days by the mail survey appeared to be less biased than those calculated by the on-site creel survey. Estimates of catch rates and catch by both survey methods were probably infl
