Proposed revision to the estimation of fisheries footprints
Abstract: A revised approach to the estimation of longline fisheries footprints is presented. The ... method uses a data-derived estimate of the uncertainty around the locations of longlines to define a ... grid. The proportion of the area of each grid cell that is covered by buffered lines is then used as a ... footprint index.

Modelling egg and larval transport of Antarctic toothfish (Dissostichus mawsoni) in the East Antarctic region: preliminary result using satellite data
larval transport of the Antarctic Toothfish in the East Antarctic region. This paper presents the ... transport pattern of particles released from plausible spawning grounds, i.e. Banzare Bank (BB: Kerguelen ... 2-year simulation. From the result of the BB region, while strong self retention on the BB was ... observed in the experiment A-1, the majority of particles were advected eastward in the experiment A-2. A ...

Feeding behaviour of Antarctic krill on salps
Abstract: Feeding behavior of Antarctic krill (Euphausia superba) on salps was observed through ... 1 salp/krill/day. Among 4 items of ethanol extracts; salps, phytoplankton, krill, and polychaets ... attractive to krill. The result of our experiment might indicate a tight ecological relationship between ... krill and salps. Since salps have ability to ingest wide size range of particles, there might also be a ...
