Abundance, size and maturity of krill (Euphausia superba) in the krill fishing ground of Subarea 48.1 during 1990/91 austral summer
Abstract: Acoustic and net sampling surveys for krill were conducted in the krill fishing area ... 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 ... krill into this zone. The total biomass over the survey region was estimated to be 1.59 ± 0.45 million t ...
