    1     Opening of the meeting

    The Con-conveners will  welcome participants, outline priorities for the meeting  and provide an overview of local  facilities, including Secretariat support, Internet access and extracurricular activities.

    2     Protocols for the collection and analysis of krill acoustic data from fishing vessels, with emphasis on Simrad echosounders (EK60, ES60/70)

    SG-ASAM will review automated methods for processing acoustic data collected on krill fishing vessels according to the established CCAMLR Protocols as outlined in the SG-ASAM-16 Report (163.47 KB).

    3     Analysis of data collected from fishing vessels

    SG-ASAM will  review data collected by krill fishing vessels during 2015/16 and 2016/17 with particular emphasis on

    1. occupation of repeat transects
    2. fishing-vessel-based regional surveys
    3. data collection during fishing operations.
