Proportional recruitment indices of Antarctic krill from Japanese fisheries data in Subareas 48.1, 48.2 and 48.3 during 1980 through 1997
from logbook data of Japanese commercial krill fisheries during 1980 to 1997. Inter-annual patterns of ... Siegel et al. (1 998)'s values. This may be due to the net selectivity and/or incomplete coverage of ... the distribution of small krill by commercial fisheries. Inter-annual pattern of R1 and R2 in Subarea ... 48.2 showed somewhat similar pattern to Subarea 48.1. However, because of inconsistency of the ...
