A Comparison Of Whole Body Mercury Concentrations Of Mummichogs (Fundulus Heteroclitus) And Atlantic Silversides (Menidia Menidia), Daniel P. Ferons
A Comparison Of Whole Body Mercury Concentrations Of Mummichogs (Fundulus Heteroclitus) And Atlantic Silversides (Menidia Menidia), Daniel P. Ferons
Electronic Theses and Dissertations
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 …
The Fish Kill Mechanism Of The Harmful Raphidophyte Chattonella Subsalsa, Amy E. Grogan
The Fish Kill Mechanism Of The Harmful Raphidophyte Chattonella Subsalsa, Amy E. Grogan
Electronic Theses and Dissertations
Harmful algae blooms (HABs) and toxins associated with HAB species are a significant threat to the health of marine species and coastal environments. In the South Carolina coastal zone, HABs have proliferated with intensified anthropogenic eutrophication in coastal waters. The raphidophyte species Chattonella subsalsa is a prominent cause of algal blooms resulting in fish kills in South Carolina. Though C. subsalsa is a known ichthyotoxic alga, the fish kill mechanism of this species remains unidentified. C. subsalsa is likely to elicit fish mortality via one of two mechanisms: (1) gill damage induced by cell contact irritation or (2) the production …
