Conceptual diagram depicting factors that may influence Hg concentrations in fish. Fish are exposed to Hg primarily through dietary uptake (1), with a smaller proportion of their Hg obtained via waterborne uptake (2). The level of Hg can be expected to decrease with increasing growth (3) and to incr
