Precision and Bias of the British Columbia Steelhead Harvest Analysis

The BC Steelhead Harvest Analysis (SHA) is a province-wide mail survey of steelhead anglers which has been conducted annually since 1967, to obtain estimates of effort and catch stratified by stream and residency. This study reports the compilation and examination of information relating to the accuracy of the survey. Objectives were to assess the capability of available data to reveal the precision and bias of SHA estimates, and to summarize how SHA results compare to steelhead fishery catch and effort parameter estimates from other sources.
