1. Analysis of observer coverage for Japanese krill fishing vessels

   Abstract:  Sources of variability of krill mean length and fish bycatch number was investigated to ... explore proper allocation of scientific observers on Japanese krill fishing vessels using the data from ... 1995 to 2008. Based on the multistage sampling theory, we derived the equation of variance in four ... coefficients of variation (CV) caused by the shifts in coverage at different sampling stages.

3. Potential climate change effects on the habitat of Antarctic krill

   summer foraging sites of many of these predators are concentrated between 0° and 90°W. Parts of this ... sector have experienced recent localised sea surface warming of up to 0.2°C     per decade, and ... projections suggest that further widespread warming of 0.27° to 1.08°C will occur by the late 21st century. We ... assess the influence of projected warming on Antarctic krill habitat quality. The results divide the ...
