Revised new Research Plan for Toothfish (Dissostichus spp.) under CM 24-01, paragraph 3 in Subarea 48.2, conducted by Chile from season 2025/26 to 2027/28

This new research plan aims to update information for toothfish in Subarea 48.2 in the Northern (NRB) and Southern Research Blocks (SRB) during the 2025/26-2027/28 fishing seasons, following a six-year data gap (2019-2025). The primary objectives are: a) obtain unbiased abundance estimates for toothfish species using design-based methods for both research areas, correcting the spatial sampling bias from previous surveys; b) characterize biological parameters including length/age structure, age-length key (ALK), reproductive data, and maturity indices; c) continue the CCAMLR tagging program with balanced spatial coverage to study connectivity between Subarea 48.2; and d) assess ecosystem impacts through bycatch species characterization and monitoring of seabird/marine mammal interaction
