1. Recommendations on estimating krill escape mortality during fishing operations: the problems and approaches

   Abstract:  The task to estimate the escape mortality of krill during the fishing operation assigned by Scientific Committee requires assessment of the total krill passed through the rope and netting parts of trawl and krill amount appeared unviable in the process of escapement. The recommendations

2. Assessment of fishable krill biomass on the basis of the acoustic surveys results using geostatistical methods

   Abstract:  ABSTRACT Applicability of geostatistical methods in processing the acoustic fields of krill density based on the acoustic survey data is demonstrated. The results obtained indicate usefulness of these methods in studying the structure of krill density field for biomass assessment in

3. Proposal to commission an independent review of the Secretariat’s data management systems

   Abstract:  1. The Secretariat manages a comprehensive, detailed set of independent or related databases which support the work of the Commission and give effect to Article XX of the CAMLR Convention. Since the establishment of CCAMLR 28 years ago, there has been no formal, in-depth audit of the

4. Update on Patch v2: a simulation program in R for evaluating spatial management strategies to conserve structure and function of ecosystems

   Abstract:  Version 2 of Patch is available. Patch is a simulation program in R for evaluating spatial management strategies to conserve structure and function of ecosystems. Patch has been defined specifically for evaluating strategies to manage bottom fisheries to avoid significant adverse impacts

5. Estimation of natural mortality using catch-at-age and aged mark-recapture data: a simulation study comparing estimation for a model based on the Baranov equations versus a new mortality equation

   Abstract:  Attempts to estimate natural mortality, as a single constant M, simultaneously with other model parameters in integrated assessments via CASAL for the Heard and McDonald Islands (HIMI, CCAMLR Division 58.5.2) Patagonian toothfish (Dissostichus eleginoides) fishery have been unsuccessful.

6. Linking predator and prey behaviour: contrasts between Antarctic fur seals and macaroni penguins at South Georgia

   Abstract:  Antarctic fur seals Arctocephalus gazella and macaroni penguins Eudyptes chrysolophus are the two main land-based krill Euphausia superba consumers in the northern Scotia Sea. Using a combination of concurrent at sea (predator observations, net hauls and multi-frequency acoustics), and

7. AMLR 2009/10 Field Season Report: objectives, accomplishments and conclusions

   Abstract:  The U.S. Antarctic Marine Living Resources (U.S. AMLR) field season completed it’s 24th season of a long-term series of studies of the Antarctic Peninsula ecosystem. Hydrographic results characterizing the waters around the South Shetland Islands indicate that several water masses

8. Mean circulation and hydrography in the Ross Sea sector, Southern Ocean: representation in numerical models

   Abstract:  Three models were used to look at the Southern Ocean Ross Sea sector circulation and hydrography. Two were climate models of low (1°) to intermediate resolution (1/3°), and one was an operational high resolution (1/10°) ocean model. Despite model differences (including physics and

9. A preliminary assessment of age and growth of eel cod (Muraenolepis sp.) and violet cod (Antimora rostrata) in the Ross Sea, Antarctica

   Abstract:  Samples of an eel cod (Muraenolepis sp.) and violet cod (Antimora rostrata) were obtained from the bycatch of the longline fishery for toothfish (Dissostichus mawsoni and D. eleginoides) in the Ross Sea, Antarctica. Counts of zones visible in sectioned otoliths were used to estimate

10. A preliminary assessment of age and growth of Antarctic silverfish (Pleuragramma antarcticum) in the Ross Sea, Antarctica

    Abstract:  Antarctic silverfish (Pleuragramma antarcticum) were sampled during a trawl survey in the Ross Sea, Antarctica. Biological data, including fish length, weight, sex, gonad maturity, liver weight and diet analysis were collected from 311 specimens. Standard length and weight were well
