Annual report of research fishing operations at Division 58.4.3a in the 2017/18 fishing season

This paper presents the annual report of a multi-Member longline survey on Patagonian toothfish (Dissostichus eleginoides) in Division 58.4.3a in the 2017/18 fishing season by France and Japan. One fishing cruise by French vessel (“Mascareignes III”) took place in May 2018 and caught 2.5 tonnes of D. eleginoides in 58.4.3a. The data set, C2 and Observer data, were provided by the CCAMLR Secretariat on the 21th August 2018. In this paper, the data set during current fishing season (2017/18) was used for reporting the quantity of data, samples collected, and results of analysis as a progress toward research millstones. The research operations in 58.4.3a have not yet been completed in the 2017/18 fishing season which means that some data may not be reflected in tables and figures at the time of submission of this document.
