4. Research plan for toothfish in Divisions 58.4.4a and 58.4.4b by Shinsei Maru No. 3 in 2012/13

   Abstract:  A tagging survey in SSRUs B and C in Division 58.4.4 a & b was conducted in the 2011/12 fishing season with the aims of providing the data required for assessments of the population structure, size, movement and growth of Dissostichus spp. in the centred area of Division 58.4.4 a

5. Method of age determination for Antarctic toothfish (Dissostichus mawsoni)

   Abstract:  This work is based on material from Antarctic toothfish, collected in the Ross Sea from December 2004 to March 2005 on the longliner “Volna”.  Age was determined for 364 individuals. Currently widely applicable "the break and burn method" was used in the present work (Chilton,

6. Movement of Patagonian toothfish (Dissostichus eleginoides) in Subarea 48.3

   Abstract:  Movement of Patagonian toothfish in Subarea 48.3 was investigated using tagging program data.  Data from 33,322 tag releases and 4,203 tag recaptures were used. The mean movement rate of both sexes combined varied from 25 to 34 km year-1.  There was no significant difference in movement

8. Data requirements for research fishing

   Abstract:  There are currently two sets of requirements for reporting data from vessels conducting fishing for research purposes (i.e. research fishing): (1) research fishing conducted under Conservation Measure 24-01 (scientific research) requires that catch, effort and biological data be reported

9. CCAMLR tagging program: tag link status update

   Abstract:  In order to reflect the level of confidence when linking a tag recapture to a tagging event, as well as an indication of the time and effort taken to make the link, the Secretariat introduced in 2011 a tag recapture link status code.  For the 2011 season, a total of 1433 tags have been

10. 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 difficulty in accurately estimating key parameters, and consequently introduce bias into an abundance
