1. Research program on resource potential and life cycle of Dissostichus species from the Subarea 88.2 A in 2014–2017

   Abstract:  Russian Federation intends to continue research in Subarea 88.2 that began in 2010-2012. The main objectives are studying of toothfish migration from SSRU 88.1 K to Subarea 88.2 A. The survey program was improved in accordance with recommendations of WG-SAM-2014 and intercessional work

2. Comparative data on size–age composition and growth of Antarctic toothfish Dissostichus mawsoni in Ross Sea, Amundsen Sea and Weddell Sea

   Abstract:  Comparative data on size-age composition and growth of Antarctic toothfish D. mawsoni in the Pacific (SSRUs 88.1, 88.2) and Atlantic (SSRU 48.5) Antarctic areas in 2005-2014 seasons are described.

3. A review of by-catch in CCAMLR exploratory toothfish fisheries

   Abstract:  Mitigating the adverse affects of commercial fishing on the environment is an integral responsibility of fisheries globally.  Efforts to reduce bycatch, to exploit previously unfavourable species and to carry out research on associated organisms have increased with time but charismatic

4. Revised research plan for toothfish in Division 58.4.4 b by Shinsei maru No. 3 in 2014/15

   Abstract:  In this document, we revise stock status assessments of D. eleginoides in research blocks C and D using CPUE analogy method, Petersen method and CASAL model, although the data of current season has not been validated and not used for the present analysis. We used updated reference area

5. The use of electronic monitoring camera system for the toothfish fishery in CCAMLR Subarea 48.3: a study case to help CCAMLR

   Abstract:  Sampling methods to determine the composition and nature of the catch of the longlining fishery around CCAMLR Subarea 48.3 have, to date, been limited to in situ line observations conducted by CCAMLR observers deployed on the fishing fleet. The collection of this data is important for

6. Deployment and recovery of an archival tag on an Antarctic toothfish in the Ross Sea

   Abstract:  Data from electronic archival tags are often used to characterise movement and migration patterns in fishes. Understanding these movement patterns is one of the key information needs for the assessment and management of Antarctic toothfish. We deployed 4 pop-off satellite archival tags

7. Preliminary stock assessment of Rajiformes in statistical Subarea 48.3

   Abstract:  Elasmobranch species, such as skates (Rajiformes), are not target species within the CCAMLR longline fisheries. However, they form a major part of the bycatch and as such it is necessary to understand the effect of each fishery on the Rajiformes population. Here we describe biological

8. Discrimination of two species of grenadier (Gadiformes, Macrouridae), Macrourus whitsoni and M. caml, in the Ross Sea region of the Southern Ocean (CCAMLR Subareas 88.1 and 88.2) on the basis of otolith morphometrics

   Abstract:  Two species of grenadier are predominatly taken as bycatch in the Ross Sea region, Macrourus whitsoni and M. caml. A total of 220 otoliths from M. whitsoni and 307 otoliths of M. caml from fish taken as bycatch in the Ross Sea on New Zealand fishing vessels in the 2011–12 fishing year

9. Using acoustic echo counting to estimate grenadier abundance in the Ross Sea (SSRU88.1I)

   Abstract:  Grenadiers (Macrourus spp.) are the main bycatch species in the exploratory longline fishery for toothfish in the Ross Sea. Previous studies concluded that acoustics methods could be used to index the relative abundance of grenadiers and be useful for exploring spatial distribution.

10. Brief analysis of tag-recapture data in Statistical Subarea 48.4

    Abstract:  This paper presents an analysis of data gained from an eight-year tagging programme of Patagonian toothfish (Dissostichus eleginoides) in Subarea 48.4. It describes the tagging procedure, the information gained about biology, growth and movement of Patagonian toothfish, and looks at the
