Résumé

A multi-year, multi-Member research program was established to map and sample the fishable areas of SSRUs 88.2 A–B north of 66° S latitude. During the 6^th - 10^th February 2015, the UK fishing vessel Argos Froyanes surveyed SSRU 88.2 A research block 4 defined in the multi-Member 88.2 offshore research survey. Bathymetric data was collected and longline fishing conducted to release tagged fish and collect information on the characteristics of the toothfish inhabiting the region. The vessel set 7 longline sets with all vessel operations conforming to the required research criteria. A catch of 49 tonnes of D mawsoni and small catch of 29 kg of two D eleginoides was taken; 150 tagged fish were released at 3.1 fish tagged per tonne and a tag overlap statistic of 85%.
