Nine years of tag-recapture in CCAMLR Statistical Subarea 48.3 – Part II: Spatial movement and analysis

This paper presents an analysis of data gained from nine years of tagging of Patagonian toothfish (Dissostichus eleginoides) in Subarea 48.3. In addition to providing information on tagging procedure, Patagonian toothfish biology, growth and local movement of Patagonian toothfish in 48.3 (presented in WG-SAM-14/35), it describes the spatial movements and regional connectivity in Subarea 48.3. The characterisation of tag recapture data from Subarea 48.3 shows that the tagging programme is successful in providing substantial information for the stock assessment and that it can give a first indication of spatial areas of biological interest, such as potential spawning and nursery grounds.
