Descriptive analysis of the toothfish (Dissostichus spp.) tagging programme in Subareas 88.1 & 88.2 for the years 2000–01 to 2010–11
Abstract: Descriptive analyses of the toothfish tagging programme in Subareas 88.1 and 88.2 are updated, including summaries of data for the 2011 season. Overall, a total of 28 458 Antarctic toothfish have been reported as released and 1417 recaptured, and 1124 Patagonian toothfish released and 67

Estimating unaccounted fishing mortality in the Ross Sea and 88.2C–G bottom longline fisheries targeting Antarctic toothfish
Abstract: Stock assessments rely upon estimates of the total mortality resulting from fishing activities. The level of mortality resulting from the loss of sections of bottom longline gear in the Ross Sea region and Subarea 88.2 Antarctic toothfish (Dissostichus mawsoni) fisheries is not currently

Pilot study using electronic satellite tags to determine movements of Antarctic toothfish in the Ross Sea region
Abstract: New Zealand will deploy four pop-off satellite transmitters on Antarctic toothfish along the Ross Sea continental slope in January 2012. They will be programmed to pop-off the fish, float to the surface, and transmit in December 2012. The purpose of this paper is to provide an

CCAMLR measures regulating the tagging of Dissostichus species, metrics used to assess vessel tagging performance, the potential for some anomalous results, and general recommendations on tagging; a view from the hauling room
Abstract: The background to the current CCAMLR toothfish tagging programme is reviewed and recent performance measures implemented by CCAMLR to control and monitor the tagging of toothfish (Dissostichus species) in exploratory fisheries carried out within the Convention Area are described.

plotImpact – software for producing image plots of spatially referenced impact assessments
Abstract: Software is presented for the automated production of standardised image plots of spatially referenced bottom fishing impact assessments. This software is submitted to WG-FSA to assist the Secretariat or CCAMLR Working Groups in the production of integrated bottom fishing impact

Investigation of the sensitivity of the Ross Sea toothfish assessment to withholding subsets of the available data
Abstract: Antarctic and Patagonian toothfish stocks in the Antarctic have been assessed within CCAMLR areas using integrated statistical catch-at-age stock assessment models. These models were initially run annually, but have been run biennially since 2007. This document investigates the impact on

Estimates of sustainable yield for 50 data-poor stocks in the Pacific coast groundfish fishery management plan
Abstract: The Magnuson-Stevens Fishery Conservation and Management Reauthorization Act of 2006 requires Regional Fishery Management Councils to set annual catch limits for all stocks or stock complexes in Federal fishery management plans beginning in 2011. Most species listed in the Pacific Coast

Depletion-based stock reduction analysis: a catch-based method for determining sustainable yields for data-poor fish stocks
Abstract: We describe a method for determining reasonable yield and management reference points for data-poor fisheries in cases where approximate catches are known from the beginning of exploitation. The method, called Depletion-Based Stock Reduction Analysis (DB-SRA), merges stochastic Stock

Depletion-corrected average catch: a simple formula for estimating sustainable yields in data-poor situations
Abstract: The depletion-corrected average catch (DCAC) formula is an extension of the potential-yield formula, and it provides useful estimates of sustainable yield for data-poor fisheries on long-lived species. Over an extended period (e.g. a decade or more), the catch is divided into a
