Developments in the CCAMLR tagging program

In order to assess the level of confidence in the link made, as well as the time and effort  taken to make the link, the Secretariat introduced a tag recapture link status code to identify the level of effort involved in linking a tag recapture to its tagging event.  For the 2011 season 673 tags have been returned;  37% provide an exact match with tag numbers  held in the database, 22 % provide an exact match with tag numbers but had inconsistent ancillary data . For those tags that did not provide exact or unique matches only 63 (9%) could not be successfully linked using additional information.
