Briefly describe the project goals and methodology
The goals of the project are to assess the relationships between predator ontogenetic stages, trophic position, prey network properties, and PCB accumulation using the red drum in salt marshes as a model system. I will collect red drum at each of three life stages (i.e. juvenile, young-adult, and mature) and associated key prey species using trammel nets and hook and line. Nets will be deployed at high tide and collected at low tide in order to sample the entire outgoing tidal cycle. Specimens will be collected for quantification of PCB concentrations and stable isotope analysis. Additionally, the top layer of sediment and above ground vegetation will be sampled at each sampling location.
Where will the project be located?
Potential sampling sites include Dean creek, Oakdale creek, Barn creek, the creek behind the marine institute, and the creeks by Lighthouse road, Dock road, and Beach road.
How will you provide GPS coordinates for study sites?
I will provide a provisional map and arrange with my sponsor to collect and register GPS coordinates
What are the expected start and end dates of the project?
Start Date: 07/14/2016 End Date: (ongoing)
How many people will access the site and at what frequency?
If by boat, minimum of three per sampling event. If by kayak, 1-2. Ideally sampling will be conducted on a daily basis until sample size has been reached, however this is subject to the tide and weather.
Keywords that describe your project
What equipment will be deployed in the field?
Trammel net (35 ft, 100ft, and 200 ft) and hook and line. At selected sites, nets will be deployed at high tide and collected at low tide in order to sample the entire outgoing tidal cycle.
Will plants or animals be collected as part of this study?
As permitted by the GA DNR collections permit (29-WJH-16-213) I aim to collect and retain a maximum of 100 individuals per red drum at each of the following size classes: >6-13", 14-23", and > 23", as well as 10 individuals per each of four associated prey species. Potential prey items may include striped mullet, whiting, menhaden, Atlantic croaker, silver perch, mummichogs, blue crabs, fiddler crabs, ribbed mussels, Atlantic oyster and possibly other bivalves. I will also be collecting 8-10 stocks of spartina at each sampling site.
What are the likely impacts of the project on the site?
Removal of sediment, flora, and fauna ( mentioned above).
Will the project design include boardwalks? If not, explain why not.
No, site will be accessed by boat or kayak.
How long will impacts persist after the research is concluded?
Impacts on the red drum population should be negligible.
