Few studies have focused on mercury cycling within salt marsh estuaries. Mummichogs (Fundulus heteroclitus) and Atlantic silversides (Menidia menidia) are two species of forage fish that live year round in South Carolina salt marshes. During high tide, mummichogs feed from the water column, sediment, and off of smooth cordgrass while Atlantic silversides prey upon zooplankton. In this study, total and methyl mercury within mummichogs and Atlantic silversides from Dunn Sound, SC were quantified and compared over four seasons throughout 2014. Gut contents were also quantified and compared to determine if there was a dietary impact on the concentrations of total …
