1. Estimates of the tag loss rates for single and double tagged toothfish (Dissostichus mawsoni) fishery in the Ross Sea

   Abstract:  The rate at which tags are lost from tagged toothfish is an important parameter in modelling of the Antarctic toothfish (Dissostichus mawsoni) populations in Subarea 88.1 and 88.2. The toothfish stocks in these areas have been assessed using data from tag-release and recapture

2. Report on the results of exploratory research fishing for crabs in Subarea 48.2 on board FV Tamango in the 2009/10 season

   Abstract:  Exploratory research voyage of F/V 'TAMANGO' proceeded from March, 23 to May, 8, 2010. Three areas were explored during the voyage: Patagonian shelf (Statistic Subarea 41.3.1), South Orkney Islands shelf (CCAMLR Subarea 48.2) and the North Scotia Ridge. Exploratory pot-line

3. A preliminary population status model for the Patagonian toothfish, Dissostichus eleginoides, on the Kerguelen Plateau (Divisions 58.5.1 and 58.5.2) using CASAL

   Abstract:  The Kerguelen Plateau (Statistical Divisions 58.51 and 58.5.2) supports the largest Patagonian toothfish (Dissostichus eleginoides) fishery in the Southern Ocean outside of the Atlantic sector. Analysis of genetic, demographic and tagging data indicates that toothfish form a

4. 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

5. 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

6. 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.

7. CCAMLR fishery information 2011

   Abstract:  Summary of fishery-related information for WG-FSA including availability of data, catches of target and by-catch species in assessed and exploratory fisheries, tagging rates and the tag overlap statistic, notifications (fisheries, research and VMEs), development of species profiles and

8. 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

9. Description of fishing gear and procedures of setting / hauling of Spanish longline system for toothfish in CCAMLR area

   Abstract:  Although Spanish longline has been used in CCAMLR fisheries for a number of years, detailed information on the fishing gear and the procedures for setting/hauling has not been described in detail and is not currently included the CCAMLR gear library. In order to contribute to the
