Estimating krill recruitment and its variabiliity
Abstract: A maximum likelihood method is developed for the decomposition of krill density at ... length data into the proportion of recruits in population sampled in a net haul survey. Preliminary ... results from a series of 5 net haul surveys in the South Atlantic and the Indian Ocean sectors of the ... 0.100. The corresponding results for two year old krill from 9 surveys are 0.552 and standard deviation ...

Proposed expansion of research block 48.6_4 for more reliable stock assessment
Abstract: At WG-SAM-15, Japan indicated it would submit a revised proposal on the design of ... research block 48.6_4 to WG-FSA-15. Here we propose the westward expansion of the research block along the ... continental shelf-slope to promote sufficient utilization of the catch limit, which would enable us to ... complete planned research and support a more reliable stock assessment. The revised design may also ...

Chinstrap penguins alter foraging and diving behaviour in response to krill size
changes in prey availability. Chinstrap penguins are dependent predators of Antarctic krill in the Scotia ... Sea region. Both the sizes of krill found in penguin diets and acoustic estimates of krill biomass ... have fluctuated in recent years. We therefore examined the diet of chinstrap penguins at Livingston ... dives were unexpectedly deep (up to 110m) and mean nighttime depths sometimes exceeded those from the ...

Krill length frequency distribution in Subarea 48.3 in January–April 1988 in relation to sources of its origin
considered in the frame of hypothesis of krill resources forming from two sources: Antarctic Circumpolar ... Current and Weddell Scotia Sea water flow. It is shown, that small krill with the mode of about 33 mm is ... distributed in the coastal zone of about 7-40 miles wide, further is situated the boundary zone at the ... distance of about 30-60 miles, beyond boundary zone occurs larger krill with the mode of about 49 mm. Krill ...

PROPOSAL FOR REVISING CONSERVATION MEASURES 24-02 (2005) AND 41-03 (2006) IN RELATION TO SUBAREA 48.4
Abstract: The provisions for fishing season and mitigation measures in Conservation Measure 24-02 ... (2005) regulating fishing in Subarea 48.4 do not currently conform to the IMAF Risk Assessment advice ... given in CCAMLR-XXIV/BG/26. The UK proposes text that should be added to CM 24-02 to bring the measure ... into line with the Risk Assessment, which would allow fishing outside season April – September if it is ...
