A series of interviews with Canadian redfish Sebastes spp. fishing industry participants active in the 1980s and 1990s was conducted to determine how fish were caught, how much was caught (reported landings, unreported landings, and discards), and the sizes of fish caught during that time. Indicators of total fish catch derived from these interviews showed that reported catch may have underestimated catch by a factor of 2 or more. The proportion of small fish landed may also have been underestimated by a factor of 150–200. The re‐examination of catches from interviews with fishermen can provide a useful context for interpreting population model abundance estimates for this stock. This interpretation can have implications for present‐day stock assessment and fishery advice.
