Brief description

Zooplankton were collected with a Rectangular Midwater Trawl (RMT 8+1 net) from 37 sampling sites on and near the Southern Kerguelen Plateau. Specimens of the euphausiid Thysanoessa macrura were selected for cohort analysis, based on lengths, and allometry (dry weights and lengths). Lipids were extracted from the animals to provide a lipid content (%) as a function of dry weight. A small number of individuals was examined further to produce profiles of the main fatty acids and fatty alcohols. Instantaneous growth rate experiments (IGR) were conducted onboard to determine growth rates of males, females and juveniles.

Notes

Purpose
The purpose of this data was to produce a detailed description of the fundamental biology of T. macrura. Further, we used the data to feed into broader analyses of the food web/s of the region; in particular highlighting the krill trophic pathway and the copepod-fish trophic pathway.
