Mercury and amino acid content relations in northern pike (Esox lucius) in subarctic lakes along a climate-productivity gradient
Mercury is a highly toxic element for consumers, but its relation to amino acids and physiology of wild fish is not well known. The main aim of this study was to evaluate how total mercury content (THg) of northern pike (Esox lucius) is related to amino acids and potentially important environmental...
