Abstract
Examining the causes and consequences of animal movement is fundamental to understanding the ecology of any species. This analysis focuses on Antarctic toothfish movements in the Southern Ocean as inferred from tagging data collected from 2001 to 2019 with a focus on the characteristics of long‐distance movements, defined as an individual recaptured greater than 200 km from their release location. The results of this analysis indicate that while adult Antarctic toothfish are generally quite sedentary a small proportion (~7%) move long distances, consistent with findings from previous studies examining movements of toothfish. There appears to be no relationship between time at liberty and long‐distance movements, no strong influence of sex and results indicate a distinct bias in the direction of long‐distance travel from release to recapture towards a counter‐clockwise direction. Frequency and scale of long‐distance movements are likely influenced by localized physical oceanographic processes and life‐history traits. Knowledge of these movements patterns remains highly important for stock assessments and the design of spatial and temporal fisheries management regimes.
