3. Measures to avoid bias in abundance estimates of Dissostichus spp. based on tag-recapture data

   Abstract:  Using the simplest form of an abundance estimator using tag-recapture data, the Lincoln ... against this bias, or to account for their effects in assessment models. In nearly all cases, examples of ... these biases. Estimates of post-capture mortality, tag detection rates and where it occurs, post-release ... depredation rates are a priority for new tagging programs and tag-based assessments.
