New CCAMLR SISO Observer Manuals and updated longline logbook

This paper presents two new observer manuals for finfish and krill fisheries. The manuals include updated information on identifying and sexing target catch species, provide guidance on standard tasks and requirements for observers as well as supplementary information to aid data collection requirements. In addition a new version of the observer longline logbook is presented, with additions to allow data collection for a focussed skate tagging programme in the Ross Sea, beginning in the 2020 season.
