An analysis of within-season recaptures of tagged toothfish

In response to a request from WG-SAM, the secretariat inspected the available data on toothfish within-season recaptures (i.e. fish that have been tagged and recaptured in the same fishing season). Despite short times at liberty, the frequency distribution of distances between tag and recapture locations for these fish was similar to that of all recaptured fish. The relative frequency of within-season recaptures varied spatially and a particular ‘hot-spot’ was found over a northern, and isolated, seamount in Subarea 88.2.
