The Secretariat was requested to generate risk profiles of overrunning catch allocations across a range of vessel capacity (or catch) and fleet sizes to help understand whether reporting requirements for the krill fishery require revision in the future. The fishery capacity and the capacity utilisation were calculated to monitor trends in krill fisheries and daily catches. These data were used to generate the risk profiles of overrunning catch allocations across a range of vessel capacity and fleet size that is presented in this paper.
Abstract:
Results from the 2020 Conversion Factor Survey of Members’ vessels participating in CCAMLR toothfish fisheries, undertaken by the CCAMLR Secretariat, are presented in this paper. All Members reported that their vessels utilized the headed, gutted and tailed processing method, however no other product type was uniformly produced by Members or vessels. The provision of Conversion Factors by Members, and/or the calculation of Conversion Factors by vessel crews and observers, was highly variable. The Secretariat recommends a focus workshop topic on Conversion Factors be convened, in particular on the headed gutted and tailed processing method, as this may elucidate the causes of Conversion Factor variability.
Abstract:
This document summarises the current state of the database of linked tags held at the CCAMLR Secretariat.
Biomass estimates for research blocks in data-limited fisheries and the resulting catch limits for the 2022 season have been determined using the trend analysis decision rules. The resulting catch limits are subject to approval by the Commission.
