Reasons of differences between distribution and density of mackerel icefish (Champsocephalus gunnari) aggregations in the South Georgia area during summer and autumn periods in different years from the bottom trawl survey data
the largest aggregations of food organisms are concentrated at the beginning of the spring period ... . Icefish concentrations were detected at the periphery of a cyclonic meander or in the centre of the ... anticyclonic circulation formed by the Weddell waters. Confinement of the fish to the boundary of water masses ... between the shelf waters and ACC was also traced. Favourable conditions for formation of dense ...

A RE-APPRAISAL OF THE TOTAL BIOMASS AND ANNUAL PRODUCTION OF ANTARCTIC KRILL
Abstract: Despite much research on Euphausia superba, estimates of their total biomass and ... revisions in acoustics have made it possible to refine previous estimates. Net-based databases of density ... and length frequency (KRILLBASE) yield a summer distributional range of ~19 x106 km2 and a mean total ... abundance of 8x1014 postlarvae with biomass of 379 million tonnes (Mt).
