The thermal acclimation ability of notothenioid fish species

Several individuals of Trematomus bernacchii and Pagothenia borchgrevinki were captured and used in an experiment to understand the ability of these fish to acclimate to increased temperatures. Individuals were thermally acclimated over 24 hours to environmental temperature, 2.5°C and 4°C and over 1 week to 6°C. Fish were maintained at these temperatures for between 0-28 days and their tissues were harvested for subsequent genetic expression analysis to understand changes in gene expression related to thermal acclimation, with a particular emphasis on lipid metabolism and membrane function.
