Description
Increased iron concentrations in fish liver is an indicator of hepatic pathology. Environmental pollutants, such as mercury, result in liver damage and putative increased hepatic iron. We collected spotted gar (Lepisosteus oculatus) livers from two southern Arkansas lakes with varying levels of mercury contamination. We quantified total liver mercury concentrations and stained histological sections for the presence of iron. Here, we present the relationships between liver mercury concentration and the observed degree of hepatic tissue iron staining. We present our findings in the context of how environmental quality may directly impact fish health and the overall health of the ecosystem
