    Resumen

    This paper represents the bycatch analysis results of a multi-Member longline survey on Patagonian toothfish (Dissostichus eleginoides) at Division 58.4.3a by France and Japan. The data set, C2 and scientific observer data, was provided by the CCAMLR Secretariat on the 3th August, 2018. In this paper, the C2 data from 2012/2013 to 2016/2017 fishing seasons was used for the analysis because scientific observers have ceased recording number and weight of by-catch fish with some lines. ANT (Antimora rostrata), GRV (Macrourus spp.), RFA (Raja taaf), and SRX (Rajihormes spp.) are common by-catch species. These common by-catch species indicate some temporal change of their by-catch pattern.
