A Baseline Studies on Plasmatic Constituents in the Notothenia Rossii and Notothenia Coriiceps in Admiralty Bay, King George Island, Antarctica

Abstract

e Antarctic Peninsula, a pristine natural system has been found to be very sensitive to changes in the environment arising from climate changes and anthropic activities. e plasmatic levels of various metabolic constituents in sh have been used to identify the e ect of environmental changes. e present study aims to establish base line of plasmatic constituents (glucose, triglycerides, cholesterol, total protein and albumin) concentrations in two Antarctic sh species, Notothenia rossii and Notothenia coriiceps, which are abundant in Admiralty Bay, King George Island, Antarctica. Blood sample collection was done by caudal vessel puncture immediately a er capture. Plasmatic levels of glucose, triglycerides and cholesterol were signi cantly higher in N. rossii, at Refuge 2 compared to the other two sites, whereas there was no signi cant di erence in albumin and total protein concentrations from the three sites. For N. coriiceps, only the albumin levels were higher at Refuge 2 compared to the other sites. e di erences in the plasma constituent’s levels may be due to the physical and chemical di erences in marine environments at sampling sites, as well as the morphological and lifestyle behavior of the two sh species.
