| Abstract: | The biological characteristics of Antarctic krill(Euphausia superba) caught by trawler in subarea 48.1 and 48.2 of CCAMLR's Convention Area around the Antarctic Peninsula from January 24th to February 11th,2010 were studied.Results showed that body lengths were from 33.65 to 65.80 mm,with the dominant length from 50.00 to 58.00mm,accounting for 60.66% of the total.Mean length in subarea 48.1was bigger than that in subarea 48.2,and average length of females was bigger than of males.Growth parameter was 2.75.... |
