6. 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

   Abstract:  During the feeding period icefish aggregations are confined to a frontal zone between ... . Icefish concentrations were detected at the periphery of a cyclonic meander or in the centre of the ... and the coastal waters. Such a confinement of fish aggregations to dynamically active zones arises ... rather from concentration of food organisms in these areas than as a result of favourable conditions for ...
