1. Towards the development of an assessment of stock abundance for Subarea 88.2 SSRUs 88.2C–G

   Abstract:  This paper frames a discussion for improving the assessment of toothfish abundance for ... SSRUs 88.2C–G. We initially provide a characterisation of the fishery and a summary of available tagging ... fish have been recaptured. It is likely that the lack of recaptures of tagged fish in this region has ... been caused primarily by the poor spatial overlap of released tagged fish with subsequent fishing ...

2. Research plan for the exploratory longline fishery for Dissostichus spp. in 2016/17 in Division 58.4.3a by France and Japan

   Abstract:  In Division 58.4.3a, since 2012, research fishing has been conducted in the research ... block by two vessels using longlines: Shinsei Maru No. 3 (Japan) and the Saint André (France). The catch ... limit for Dissostichus spp. is 32 tonnes and the total reported catch up in 2014/2015 was 15 tonnes. A ... technical problem for the French vessel had shortened the fishing campaign. In this proposal, France and ...
