Résumé

In 2016, the USA and New Zealand began a collaborative initiative to describe Antarctic toothfish (Dissosticus mawsoni) movement and habitat preferences in the Ross Sea (Subarea 88.1) using pop-off satellite archival tags (PSAT) tags. Fish were tagged as part of research longline efforts in the southern shelf and northern seamount regions. A total of 10 PSAT tags of two tag types were released on the southern Ross Sea shelf in the austral summer, and 5 PSAT tags were released on the northern seamounts in the austral winter, for a total of 15 PSAT releases. All fish were also double tagged with standard CCAMLR dart tags. Releases were distributed across 5 different SSRUS within Subarea 88.1.
