USF using 3D printed clay structures to restore oyster populations
A pilot installation in Tampa Bay is the first step in a multi-year effort to rebuild marine habitat lost to urban development
Students and faculty at the University of South Florida (USF) have installed 3D printed clay structures along the seawall of Bayboro Harbor in St. Petersburg, Florida, as part of a research initiative aimed at reversing the decline of oyster populations in Tampa Bay.
The 3D printed structures have been designed to function as a living seawall capable of supporting thousands of oysters, and each is able to filter thousands of gallons of water per day. They have been dubbed “oyster restoration brick structures” (ORBS), and are shaped in a honeycomb pattern.
“Our oyster restoration brick structures serve as ideal habitats for oysters while fusing art with innovative design,” said Tina Piracci, professor at the USF Honors College. “The overall goal is to reverse the decline of oyster populations in Tampa Bay that have plummeted due to development, and as more seawalls with synthetic materials are constructed.”
Students conducted site assessments, operated the 3D printers, installed the habitat structures, and carried out environmental research as part of their coursework.
Pilot project sets stage for broader deployment
Oysters’ role in the marine ecosystem’s health is crucial, as they filter water to reduce excess nutrients and mitigate harmful algal blooms. The reef structures they form shelter more than 300 marine species and help protect shorelines from erosion.
USF biology students will monitor fish populations and behavior following the Bayboro Harbor installation, while also developing protocols to measure oyster growth over time.
The project team plans to install approximately 30 structures across southeast St. Petersburg over the coming years. Open-source design files will be made available so other educational institutions can replicate, modify, and deploy their own reef structures.
The initiative is operating under The Habitat Laboratory, a partnership that includes USF’s College of Design, Art and Performance, Clearwater Marine Aquarium, and a number of other educational and environmental organizations.
