WG-EMM-2023/05 Подробнее	Current krill sampling protocols followed by fishery observers undersample small krill and underestimate the proportion of juvenile krill caught D. Bahlburg, L. Hüppe and B. Meyer Резюме: As an essential part of the krill fishery management imposed by CCAMLR, fishery observers are regularly deployed onboard commercial fishing vessels to monitor the fishing operations. One of their tasks is to take regular samples of the caught krill to record length-frequency distributions and stage composition. These data provide important information on the stage- Read More Представлено (имя): Professor Bettina Meyer (Германия) Утверждено (имя): Professor Bettina Meyer (Германия) Запросить документ совещания	4

WS-KFO-2023/02 Подробнее	Krill Observer Workshop, what to expect G.P. Zhu and S. Kawaguchi Резюме: This paper provides a brief summary of scientific observer activities for krill fishery and how it informs fishery management, especially in the context of CCAMLR’s krill work plan development and new krill fishery management approach. The workshop will review the data sampling protocols, discuss workloads, and refine Read More Представлено (имя): Professor Guoping Zhu (Китай) Утверждено (имя): Dr Xianyong Zhao (Китай) Запросить документ совещания	2
WS-KFO-2023/03 Подробнее	An investigation of variability in krill length and observation duration of scientific observer involving in krill biological data collection in Antarctic krill fishery G.P. Zhu, Z.H. Zheng and S. Qiu Резюме: The CCAMLR Observer Manual details scientific observation guidelines and contains a set of logbook forms with instructions for recording observation, and krill length distribution and time budget are two key aspects related to Scientific Observation. This document investigates the variability in krill length under 4 sampling strategies, i.e., 50 Read More Представлено (имя): Professor Guoping Zhu (Китай) Утверждено (имя): Dr Xianyong Zhao (Китай) Запросить документ совещания	3, 4
WS-KFO-2023/04 Подробнее	Data quality screening for data reported from vessels and observers in the krill fishery K. Huang, D. De Pooter and S. Parker Резюме: This study focuses on addressing data quality issues in the CCAMLR krill fishery database, particularly related to data consistency and accuracy. Historical data links between observer data and C1 vessel data were examined which resulted in 5660 newly created links. Data accuracy issues were also identified, including unit errors and missing values, which affect the analysis of fish by-catch Read More Представлено (имя): Mr Daphnis De Pooter (Секретариат АНТКОМ) Утверждено (имя): Dr David Agnew (Секретариат АНТКОМ) Запросить документ совещания	4
WS-KFO-2023/05 Подробнее	Draft data collection form for whale incidental mortality events in the krill trawl fishery N. Kelly Резюме: During its 2022 meeting, WG-IMAF noted the need to develop a data collection template and accompanying instructions for krill trawling vessels to report standardised data in the event of a whale mortality event. Independent of WG-IMAF discussions, the US Marine Mammal Commission generously provided to IWC-SC a potential data collection form for recording information on whale Read More Представлено (имя): Dr Nat Kelly (Австралия) Утверждено (имя): Dr Philippe Ziegler (Австралия) Запросить документ совещания	4
WS-KFO-2023/06 Rev. 1 Подробнее	A summary of current SISO observer tasks in the krill fishery, and responses to the krill observer survey questionnaire. CCAMLR Secretariat Резюме: This paper provides details of current observer tasks conducted by designated SISO observers in CCAMLR krill fisheries, and a summary of responses received from the krill observer survey questionnaire that was circulated to SISO technical coordinators prior to this workshop. The details provided in this paper are to inform the discussion around future tasking and prioritization for SISO Read More Представлено (имя): Mr Isaac Forster (Секретариат АНТКОМ) Утверждено (имя): Ms Catherine Stubberfield (Секретариат АНТКОМ) Запросить документ совещания	3
