1. Results of reading tests of TOP otolith sections and time schedule of reading for Dissostichus otoliths caught in regions of data-poor fisheries

   Abstract:  The correct age-length keys are essential for the stock assessment of Dissostichus spp. by CASAL model. However, the age estimations using the otoliths have been scarcely progressed in regions of data-poor fisheries. Therefore the analysis is an urgent task. We have made five reading

2. Reports on abundance and biological information of toothfish in Division 58.4.4a & b by Shinsei Maru No. 3 in 2012/13 season

   Abstract:  A survey was conducted to collect data of stock status and various biological information of toothfish in SSRUs C and D of Division 58.4.4a & b (Ob Lena Banks) from April 25 to May 22, 2013. A total of 64 research hauls using normal trotline system were made in SSRUs C and D. Total

3. Research plan for toothfish in Division 58.4.4a & b by Shinsei Maru No. 3 in 2013/14

   Abstract:  We made stock status assessments of Dissostichus eleginoides in SSRUs C and D in Division 58.4.4 a & b. Regarding SSRU C, the stock size was estimated by using following six methods; 1) comparative CPUE analysis, 2) modified Lincoln-Petersen 3) CASAL_base model, 4) CASAL_YCS_fix

4. Operational difficulties in exploratory fisheries

   Abstract:  F/V Shinsei Maru No.3 has been engaged in Exploratory Fisheries since 2003. Furthermore the vessel has conducted research activities under CM24-01 in division 58.4.4 since 2008 and provided significant scientific information on toothfish. For the rational utilization of toothfish

5. Results of research program of the Russian Federation in Subarea 48.5 (Weddell Sea) in season 2012/13

   Abstract:  Research program in data-poor Subarea 48.5 (Weddell Sea) have been carried out for the first time. New commercial and biological data on the target (Dissostichus mawsoni Norman, 1937) and by-catch species have been collected. Toothfish tagging program have been executed. Distribution of

6. Review of fishery monitoring and forecast procedures

   Abstract:  The Secretariat monitors the catches of all target and by-catch species (or species groups) in CCAMLR fisheries, including catches taken from small-scale research units and other management areas where catch limits apply. Each season, approximately 130 catch limits are monitored and a

7. Further development of a spatially explicit population dynamics operating model for Antarctic toothfish in the Ross Sea region

   Abstract:  We present an optimised spatially explicit age-structured population dynamics operating model for Antarctic toothfish over the entire Ross Sea region, for a medium scale spatial resolution (189 spatial cells) covering the Ross Sea region. The model was developed as a generalised Bayesian

8. Investigation of potential biases in the assessment of Antarctic toothfish in the Ross Sea fishery using outputs from a spatially explicit operating model

   Abstract:  Toothfish stock assessment results are strongly influenced by tag-release and tag-recapture data, and rely on the assumption that tagged and untagged fish have constant probabilities of recapture regardless of the spatial distribution of releases or subsequent fishing effort for

9. Considerations for research plan design and implementation in data-poor fisheries

   Abstract:  The Scientific Committee has provided detailed advice on the preparation and evaluation of research plans in data poor fisheries submitted under CMs 21-02 and 24-01 in 2011 and in 2012. We formulate advice arising from extensive Working Group discussions and highlight additional design
