Abstract

My internship project at the NOAA SEFSC entailed the analysis of the pink shrimp (Farfantepenaeus duorarum) using species count and environmental information obtained from the Florida Fish and Invertebrate Assessment Network (FIAN) and the Faunal Monitoring in response to Harbor Dredging (FMHD) in relation to the enlargement of the Port of Miami to accommodate Panamax-size vessels. Species count of the pink shrimp and environmental variables were organized and analyzed to obtain information and compare between pre- and post- dredging conditions in Port Miami, using Northern Biscayne Bay as a control. Abundance of shrimp fluctuated with seasons and between years, but was strongly correlated between the Port of Miami and Northern Biscayne Bay. The dredge event itself did not significantly affect average shrimp abundance at the Port of Miami, however the dredging had direct effects on shrimp habitat variables (turbidity, seagrass canopy height) that were shown to affect abundance. This implies that any losses of seagrass and changes in turbidity resulting from the dredging would have reduced the overall population size of shrimp in the Port of Miami. The size of this reduction does not seem to have been large in comparison with the natural fluctuations in shrimp populations observed during the period of study. This information will contribute to determining the ecological effects of the port expansion and assist planning future marine construction projects of a similar nature, such as the Port Everglades expansion project.
