Catch and effort data
Catch and effort data is used to monitor CCAMLR fisheries and to forecast fishery closures.
Catch and effort data is submitted to the Secretariat by Flag States, or their vessels, using the CCAMLR data forms. Catch and effort data is submitted at different reporting periods depending on the conservation measure (CM) that applies to a fishery and the status of the fishery in relation to its catch limit.
Daily catch and effort data
Daily catch and effort data is submitted in accordance with Conservation Measure 23-07 and is required for all exploratory toothfish fisheries.
5-day catch and effort data
5-day catch and effort data is submitted in accordance with Conservation Measure 23-01 and is required for established toothfish and icefish fisheries (except Division 58.5.2), established krill fisheries when krill catches exceed 10–80% of their respective limits (see monthly catch and effort reporting) and during research fishing undertaken in accordance with Conservation Measure 24-01.
10-day catch and effort data
Monthly catch and effort data
Monthly catch and effort data is submitted in accordance with Conservation Measure 23-03 and Conservation Measure 23-06 for established krill fisheries in Subareas 48.1, 48.2, 48.3 and 48.4 and Divisions 58.4.1 and 58.4.2 when the total catch is less than 50–80% of the trigger level or 10% of the trigger level in Subarea 48.1 (CCAMLR-XXXIII, paragraph 5.5).
Catch, effort and biological data reporting is also required on a haul-by-haul (fine-scale) basis. This data is used to characterise fisheries, quantify catches of target and by-catch species, incidental catches and removal of vulnerable marine ecosystem (VME) indicator species, estimate fishery and biological parameters and assess fish stocks.
The reporting of catch and effort data on a haul-by-haul basis is required in all fisheries. The data must be submitted before the end of the month after the month when the data are collected in accordance with Conservation Measure 23-04.
Haul-by-haul (fine-scale) data is also required in special cases where the equivalent data is not collected and submitted by the CCAMLR Scheme of International Scientific Observation (SISO). In such cases, the data must be submitted before the end of the month after the month when data are collected in accordance with Conservation Measure 23-05.
