Water Flow in Florida U.S. Army Corps of Engineers, Jacksonville District

Comprehensive Everglades Restoration Plan (CERP) CERP implemented as a means of reinitiating natural freshwater flow to both coasts of south Florida Monitoring component of CERP addresses impacts of changed FW flow on the flora and fauna Eastern oyster chosen as a target species for CERP

Study Sites IMPACTED SITES St. Lucie Estuary Loxahatchee River Lake Worth Lagoon Biscayne Bay CONTROL SITES Tampa Bay Mosquito Lagoon Sebastian River

Mosquito Lagoon Pristine environment Located within Canaveral National Seashore Few anthropogenic or freshwater inputs

Mosquito Lagoon Stations 2 3 1

St. Lucie Estuary Urban environment Increasing levels of development, industry and agriculture Flood control canals and drainage ditches

St. Lucie Estuary Exposed to altered patterns of water quantity and quality excess wet season flows insufficient dry season flows extreme salinity fluctuations High sediment and pollutant inputs

St. Lucie Stations 1 1 2 North Central 3 2 3 1 South 2 3

Salinity Patterns

Juvenile Recruitment Monthly sampling 3 replicate spat arrays at each station Count live oysters on underside of each strung shell

Juvenile Recruitment

Abundance and Distribution Twice per year 10 replicate 1-m2 quadrats at each station Count total live and dead oysters Measure SH of 50 live oysters

Abundance and Distribution

Perkinsus marinus (Dermo) Monthly sampling Collect and dissect 15 oysters from each site Process gill and mantle tissues with RFTM Parasite density ranked with Mackin scale

Perkinsus marinus (Dermo)

Summary Mosquito Lagoon St. Lucie estuary Mean Max Min Salinity 33.6 42.4 26.1 11.1 29.5 0.20 S.D. % Recruitment 1.35 2.52 0.28 1.10 Density 43.0 53.3 96.2 144.4 Shell Height 53.0 26.3 28.4 8.7 Dermo 0.43 0.71 46 0.05 0.25 9

Conclusions The prevalence and intensity of dermo infection is greater at the high salinity Mosquito Lagoon site than at the more variable salinity St. Lucie site Nevertheless, oysters in Mosquito Lagoon exhibit higher recruitment rates and less variable adult populations relative to the St. Lucie estuary The indirect (negative) effects of salinity appear to exceed the direct effects of dermo on oyster health and abundance in east coast Florida waters In FLORIDA SOUTHEAST COAST ESTUARIES, it may be premature to conduct oyster reef rebuilding operations until freshwater entering those estuaries is properly managed
