From the St. Johns River Water Management District
The St. Johns River Water Management District and Brevard Zoo today celebrated the launch of an innovative cost-sharing project to reintroduce clams into the Indian River Lagoon with the goal of establishing new clam populations in the estuary.
“Since 2016, we’ve collaborated with 52 partners on projects targeted to improve water quality in the Indian River Lagoon,” said St. Johns River Water Management District Executive Director Dr. Ann Shortelle. “This particular cost-share project is special because it reintroduces a native species that filters water in the lagoon while taking advantage of the Brevard Zoo’s ability to organize and involve volunteers in the endeavor.”
Brevard Zoo is leading the project, which calls for establishing clam sites at 100 locations in the Indian River Lagoon. The bivalves will begin filtering and improving the water quality of the Indian River.
“After seeing early promising results from our oyster restoration and living shoreline projects, we are eager to begin working with clams as another tool to improve water quality in the Indian River Lagoon,” said Brevard Zoo Executive Director Keith Winsten. “We are grateful to the St. Johns River Water Management District and the State of Florida for investing in this new endeavor to restore critical ecosystem services.”
Whitney Laboratory for Marine Bioscience, a University of Florida research center in St. Augustine, will provide a nursery-raised hard-shell clam known for surviving brown tide and other algal bloom events. Seed clams will be added to several of the Zoo’s existing oyster restoration reefs, as research shows both clams and oysters have greater survival rates when together. Some sites will be planted with aquatic grasses cultivated by the Florida Oceanographic Society in Stuart. The project includes long-term monitoring to evaluate and track clam survival rates.
The District provided $1.03 million for the project through its cost-share program, with Brevard Zoo contributing a local match of $90,676.
