Quantifying vessel performance in the CCAMLR tagging program: spatially and temporally controlled measures of relative mortality and tag-detection rates
CCAMLR of a number of toothfish fisheries in Antarctica, but the evaluation of tagging performance has ... detection rate of recaptured fish. This method was applied to the tagging data in CCAMLR Subareas 88.1 and ... 88.2. Results show that the indices developed can provide evidence of significant differences in ... indices are robust to the choice of the control group and the area included in the analysis, as well as ...
