Oyster Farming Demonstration Project
Application of Triploidy to the Emergent Florida West Coast Industry
This project allows for large-scale demonstration and evaluation of an oyster breeding process to local conditions on Florida’s west coast by oyster growers. The objectives are two-fold:
- Document production performance, assess health, and evaluate the quality (sensory characteristics) of diploid (2N) and triploid (3N) oysters under commercial conditions, and
- Quantify the effects of different culture methods, salinity regimes, and seasonal harvests.
SCOPE OF WORK: Oysters from two ploidy types (triploids – 3N and diploids – 2N) and two seasonal spawns (spring and fall) are being provided to certified growers, who have obtained approval from DACS to culture oysters on their shellfish aquaculture leases. Eleven growers in four west coast counties (Charlotte, Franklin, Levy, and Wakulla) are using a variety of culture systems (floating bags, bottom cages, and adjustable lone lines), which allows for evaluation of site and gear interaction on ploidy type. University of Florida (UF) faculty are also culturing oysters at their research lease off Cedar Key to document growth and survival and evaluate gear types, stocking densities, and antifouling coatings.

Single-set triploid oyster seed were produced by crossing Cedar Key stocks with sperm from tetraploid stocks maintained at Louisiana Sea Grant’s oyster hatchery. Read more
Triploid and diploid oyster stocks were also planted by UF at their experimental lease located within the Dog Island Lease Area off Cedar Key on August 4.
