Distribution of mackerel icefish by size-group at South Georgia
Abstract: The depth distribution of C. gunnari was investigated with data from 9 groundfish ... of 8 depth strata with mean depths of 112, 137, 165, 185, 208, 230, 257 and 308 m. Fish were divided ... into size groups representative of age-classes. Kruskal-Wallis tests on log-transformed median ... abundance (number of fish km?2) indicated that depth of maximum abundance increased as the size of the fish ...
