This paper provides a review of the three main trawling systems used to target Antarctic krill: traditional, continuous fishing systems and fishing systems utilising pumping to clear the codend. Common terms used in reference to trawling techoniques and gear are defined, with specific emphasis on continuous trawling. The operational procedures for trawl vessels targeting krill in the Read More

• Information was taken from CCAMLR observer reports and interviews with fishing masters;
• The variation in reported conversion factors for similar reported products can be attributed to a number of reasons:.;
  o Differences in the method of processing the same products
  o Seasonal variation o Spatial variation
  o Krill water content
  o Reporting errors ( Read More

The aim of this document is to serve as an objective guideline to decide on an appropriate observer coverage to understand overall behaviour and impact of the fishery. CCAMLR Observer data, together with haul-by-haul fine-scale data were used to identify the target SSMUs and the critical periods as baseline to evaluate the level of observer coverage needed to achieve the CCAMLR objectives. The Read More

Conservation Measure 22-07 (2008) requires vessels fishing in the Ross Sea region (and most areas south of 60 °S) to monitor longline bycatch for VME indicator organisms. Observers classified invertebrate bycatch using new protocols and a new VME taxa classification guide, and retained these samples for subsequent onshore classification by taxonomists. Comparison of the observer’s Read More

Illegal, unregulated and unreported (IUU) fishing vessels are increasingly using gillnets as a fishing method to target toothfish in the Convention area. Estimating the impact of IUU fishing is hampered by a lack of data on the design, deployment, catch and bycatch rates of gill nets. This paper describes a gillnet found abandoned by Australian vessel patrolling BANZARE Bank (Statistical Read More
