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 ... -Petersen equation, we summarise the processes that may occur during a tagging program that lead to ... estimate. We also review the methods that have been used in CCAMLR tag recapture to program to mitigate ... depredation rates are a priority for new tagging programs and tag-based assessments.
