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 rate between male and female fish of the same maturity category. Male and females with developed, ripe and spent or resting gonads had significantly lower movement rates than immature females.
There was significant negative positive correlation between movement rate and local toothfish density at the point of release.
