1. Development of an acoustic sensor to estimate catch directly from the trawl during continuous krill harvesting

   Abstract:  This paper describes experiments and plans for development of an acoustic sensor to support  precise catch reporting for the continuous krill harvesting fishery.  Author(s):  O.R. Godø, B. Krafft and F. Grebstad Title:  Development of an acoustic sensor to estimate catch directly from

2. Report of the Workshop on data and modelling issues relevant to the planning of a potential Marine Protected Area (MPA) east of the zero meridian in the Weddell Sea (MAUD)

   Abstract:  The workshop was convened to follow up the agreement in the 2018 meeting of CCAMLR on an approach to facilitate progress on the further development of the Weddell Sea MPA proposal. In its report, the Commission referred to how Norway: 1) encouraged agreement during that meeting on

3. Trials with net monitoring cable during the 2017/18 and 2018/19 seasons onboard FV Saga Sea

   Abstract:  This paper describes trials with a net monitoring cable on board FV Saga Sea. The solution as described in the permit for using a third cable was abandoned at an early stage, as it was operable only when using one trawl behind the vessel. Trawling from the two beams caused practical

4. Supporting industry sustainability and CCAMLR monitoring with Sailbuoy operations

   Abstract:  This paper describe tests with the Sailbuoy during the 2019 RV Kronprins Haakon cruise in the Antarctic. The trials were successful giving data during continuous operations from end of January to mid February. We present data demonstrating capabilities to run survey transects, to observe

5. Empirically-driven feedback management incorporating multi-scale risk assessment and an experimental framework to facilitate adaptive improvement

   Abstract:  Currently, several approaches to FBM have been tabled to CCAMLR – Risk Assessment (RA: Constable et al. 2016), experimental fishing (EF: WS-SM-18/05) and Decision Rule approaches (DR: Watters et al. 2016), and recently a more empirical approach using a combination of fishing fleet

6. Exploring trends of the krill fishery indicators among the NWAP D1MPA zones in the Subarea 48.1

   Abstract:  Domain 1 marine protected area (D1MPA) proposal has been developed sin 2012 and now has been intensively discussed. Its implementation will establish a new scenario for the current krill fishing fleet dynamic, therefore it is necessary to understand what represent each D1MPA zones for

7. Detection of predator dive patterns from stationary echosounder data

   Abstract:  Standard protocols for processing of echosounder data are geared towards the estimation of biomass indices of pelagic organisms. More transient visitors to the watercolumn however also give echoes, and the data provided by the echosounders may be used to assess the behaviour of these

8. Annual migrations of pelagic fish stocks into a krill hotspot

   Abstract:  We report here on the existence of seasonal fish migrations into a krill hotspot, utilized both by central place foragers and the industry. We do not have trawl samples overlapping with the acoustic data, but the behaviour displayed suggests that the fish are planktivorous. Furthermore,

9. Using stationary acoustic platforms to assess precision and accuracy of acoustical krill surveys

   Abstract:  The current CCAMLR protocol specifies daytime acoustic sampling in order to avoid issues of krill migrating too close to the surface to be acoustically detected, as well as potential issues of diel changes in acoustic scattering strengths. However, due to logistic constraints, acoustic

10. Preliminary results on the observations of cetaceans in the CCAMLR Statistical Subareas 48.1 and 48.2

    Abstract:  Visual observations of cetaceans were conducted aboard the Ukrainian krill fishing vessel More Sodruzhestva. Observations were made during December 2018 – to January 2019 in Subareas 48.1 and 48.2. 66 baleen whale registrations were recorded. Whale’s behavior was observed and analyzed.
