Abundance, size and maturity of krill (Euphausia superba) in the krill fishing ground of Subarea 48.1 during 1990/91 austral summer
north of the South Shetland Islands from 18 January to 3 February 1991. Distinct offshore-inshore ... heterogeneities in abundance and maturity of krill were observed. The survey region was divided into four zones ... ; oceanic, slope frontal, neritic and nearshore zones. The mean density of krill was low in the oceanic zone ... (95% confidence limit), of which 1.22 ± 0.42 million t was concentrated in the fishing grounds (" ...
