Sensitivities in the assessment of the Patagonian toothfish (D. eleginoides) in Subareas 48.3 and 48.4 to truncation of tagging data
Abstract: The assessment of toothfish in CCAMLR subarea 48.3 currently uses the first four years ... of tag recaptures post release as input data, whereas the assessment in subarea 48.4 uses all ... available recapture data (excluding in-year recaptures). A theoretical analysis of the use of data from ... introduce bias into the assessment. Sensitivity tests on both stocks show that this bias occurs in practice ...
