Fine-Scale Geographic Variation Of Stable Isotope And Fatty Acid Signatures Of Three Fish Species In The Indian River Lagoon, Fl, Jennifer Fletcher Odom
Fine-Scale Geographic Variation Of Stable Isotope And Fatty Acid Signatures Of Three Fish Species In The Indian River Lagoon, Fl, Jennifer Fletcher Odom
Electronic Theses and Dissertations
The Indian River Lagoon, Florida, is a unique closed “bar built” estuary system that has little interchange with the Atlantic Ocean and which is home to many resident species. Three fish species were investigated to see if their isotopic and fatty acid signatures differed based on geographic location. The goal was to assess the degree of resolution of spatial variation that is possible when using stable isotope and fatty acid signature analysis to interpret feeding habits and potential linkages between feeding habits and health status. Spotted seatrout (n=40), pinfish (n=60) and white mullet (n=60) were collected over a 4 week …
