Brief Description (Abstract):

The slow but steady increase in temperature in the Antarctic ecosystem has been a cause of concern and raises questions on the adaptability of polar marine ectotherms to the variation in the environmental factors. In this study, metabolic rates of Antarctic Krill were determined in the austral summer of 2009 in the Prydz Bay region of east Antarctica during the 28th Indian Scientific Expedition to Antarctica. Live individuals of Euphausia crystallorophias were maintained onboard under controlled laboratory conditions between a temperature range of 0 to 6 ?C and the effects of temperature (T) on oxygen consumption (O2), ammonia excretion (NH3) and phosphate excretion (PO4) rates were quantified.

Status: Completed

Purpose: The present study enables a preliminary understanding of the physiological responses of Antarctic krill towards a possible rise in seawater temperature in the future.
