Important catches of sea pens (Pennatulacea, NTW) in the 58.4.4b sector (Lena bank) have been reported during the CCAMLR SAM Working Group 2018 (see WG-SAM-18/31 "Annual report of research fishing operations at Division 58.4.4b in 2016/17 fishing season" by Japanese and French delegations).

Detail of French catches, with abundances and weights are provided here (Tab.1). Data and specimens have been collected according to the French protocol for benthic invertebrate survey, which includes the exhaustive collection of the organisms caught by the longlines (see WG-EMM-17/09). This report does not include the latest data collected.
