Biomass of Antarctic krill (Euphausia superba) off east Antarctica (30–80°E) in January–March 2006
relatively weak aggregations (s A <100 m 2 nmi-2 for each 2 km-alongtrack integration interval), with 50 ... % of integration intervals containing backscattering values <10 m 2 nmi-2. Half of the biomass was ...

Age and growth of the Antarctic skate (Amblyraja georgiana) in the Ross Sea
the curve for both sexes provides the best available representation of growth in the species: Lt ... = 70.8(1-e-0.308[t+1.10]), where Lt is the pelvic length (PL) in centimetres at age t. Applying this ...
