Intra-regional similarities and inter-regional differences in wild steelhead (Oncorhynchus mykiss) abundance patterns over time throughout British Columbia were identified using Catch-per-Angler-Day (CpAD) as an index of abundance of wild in-river adult steelhead abundance. This index was calculated from data collected by the Steelhead Harvest Questionnaire (SHQ) from 1967/68 until 1995/96. Time-series and other analyses rejected hypotheses that changes in fee schedules, regulations affecting an angler's entitlement to retain wild steelhead, the actual percent retention of wild steelhead (i.e., percent catch-and-release), sport anglers' methods/skills, angler residency, etc. are generally important factors affecting real or apparent trends in wild steelhead CpAD. However, after 1992/93, the introduction of mandatory catch-and-release, and mitigation of steelhead interception and retention by marine commercial salmon fisheries may have increased wild CpAD for the Skeena and Nass watersheds.
