WG-EMM-95/04 More Info	Krill distribution variability and fishery conditions within the local ground of Subarea 48.3 in June 1991 Kasatkina, S.M. Abstract: Experiments on estimation of krill transport by a current and its distribution characteristics variability were carried out within a local ground of Subarea 48.3 in the fleet operation area. It is shown that krill transport by wat4er flow across the fishing ground results in variation of fished krill aggregations distribution, and thus, in unstable indices of fishing vessels activity.

WG-EMM-95/08 More Info	Comparison of equal-area cylindrical and circular piston transducers Foote, K.G. Abstract: Design of sondes for in situ measurement of zooplankton or other scatterers requires choosing among alternative transducer geometries. This contribution addresses the problem of choosing between cylindrical and circular piston transducers by comparing the performance of the two according to the principle that the acoustically active areas be equal.

Abstract: In connection with future calculation of volume of krill immigration/emigration (flux) in the choosen polygones, the proves of active long-distance migrations of krill are considered.

WG-EMM-95/23 More Info	Temporal scales of foraging in a marine predator: implications for interpreting the distribution of prey Boyd, I.L. Abstract: The pattern of prey distribution can profoundly affect the foraging behavior and success of a predator. In pelagic marine ecosystems, where prey is often patchily distributed, predators must be able to adapt quickly to changes in the spatial patterning of prey. Antarctic fur seals feed primarily on krill, which is patchily distributed. When combined with information about swimming speed on the Read More Submitted By: Admin Admin (CCAMLR Secretariat) Request Meeting Document

WG-EMM-95/25 More Info	Swimming speed and allocation of time during the dive cycle of Antarctic fur seals Boyd, I.L., K. Reid and R.M. Bevan Abstract: During sustained bouts of diving, predators like fur seals may adjust the time they spend diving to maximise the time they can spend foraging and minimise the time spent at the surface between dives. To examine this, swimming speeds and the time allocated to different parts of the dive cycle were measured in 10 adult female Antarctic fur seals (Arctocephalus gazella) while they were foraging Read More Submitted By: Admin Admin (CCAMLR Secretariat) Approved By: Admin Admin (CCAMLR Secretariat) Request Meeting Document

WG-EMM-95/39 More Info	On the consequences of differentiating between adult and sub-adult survival rates in the krill-predators model Thomson, R.B. and D.S. Butterworth Abstract: The krill-predators model is generalised by splitting post-first-year animals into adults and sub-adults, with different survival rates for these two groups. Broadly speaking, the sub-adult survival rate can be adjusted to ensure that the modelled predator population reflects observed growth rates, thus solving problems of lack of self-sustainability encountered in earlier model analyses.

Butterworth Abstract: A method is put forward which estimates the proportions by which the annual consumption of krill is split between predator species. This method uses data on the length distribution of krill from predator stomachs. The proportions estimated depend, through the krill yield model, on the schedule of krill natural mortality at age. In principle, such a method would allow inferences about this Read More Submitted By: Admin Admin (CCAMLR Secretariat) Approved By: Admin Admin (CCAMLR Secretariat) Request Meeting Document

The variance in system calibration with a standard sphere was evaluated in relation to sphere material and diameter, water temperature, and pulse length (Demer and Hewitt, 1992). Calibration bias was investigated by comparing the theoretical and actual target strength (TS) values of four Read More Submitted By: Admin Admin (CCAMLR Secretariat) Request Meeting Document

Watkins Abstract: Dual frequency (38 and 120 kHz) acoustic surveys were carried out in two regions along the northern coast of South Georgia from RRS lames Clark Ross during January 1994. Difference in signal strength between the two frequencies (δMVBS = MVBS 120 kHz - MVBS 38 kHz) was used to discriminate krill from other acoustic targets.
