    ABSTRACT
    The paper presents an estimate of IUU catches of toothfish during the 2009/10 fishing season, using the
    standard, compliance derived methodology.
    The paper was revised on 4 October 2010 to take into account new information submitted in
    respect of two vessels fishing in Divisions 58.4.1 and 58.4.4a. Changes from version 1 are
    highlighted in bold.

    ESTIMATION OF IUU CATCHES OF TOOTHFISH INSIDE THE
    CONVENTION AREA DURING THE 2009/10 FISHING SEASON
    BACKGROUND
    The Secretariat has prepared an estimate of IUU catches of Dissostichus spp. in the
    Convention Area for the 2009/10 season using the existing compliance-derived methodology.
    This methodology calculates total IUU catch levels as a product of the fishing time of IUU
    vessels and likely daily catch rates. The fishing time of IUU vessels is based on reports on
    the presence of IUU vessels in the Convention Area. Verified reports of undocumented
    landings and trade may also be taken into consideration if they show that IUU fishing for
    toothfish has occurred and which has not already been attributed to a sighting report.
    Information on the estimated number of days fished has generally been obtained from reports
    of patrols and inspections, the CDS database or from the logbooks of IUU vessels where
    available. Catch rates of IUU vessels are generally based on catch and effort reports from
    licensed longline fisheries from the same area unless more precise information is available,
    eg. information from IUU vessels.
    2. At CCAMLR-XXVIII, the Secretariat was also requested to provide revised estimates
    for gillnet catches for previous years and estimates of IUU catches of both D. eleginoides and
    D. mawsoni (CCAMLR-XXVIII, paragraph 9.12).
