Oglethorpe Oysters:

Marshing through time

Oglethorpe Oysters is a collaborative project between Oglethorpe Charter School in Savannah, Georgia and the Georgia Aquarium in Atlanta, Georgia.

Our project is on oysters . Oysters are very important and have many uses. They give the smaller animals food and are very nutritious. Native Americans ate large amounts of oysters. People on barrier islands used those oysters to make houses and shelter. That’s why the houses you see here aren’t made of bricks or wood. They’re also used to filter water in the ocean. One single oyster can filter up to 50 gallons of water. They also give shelter and protection to the smaller fish that live in the water. Finally, people like to eat them!

Ossabaw Island

Ossabaw Island is a Georgia barrier island that is South from Wassaw Island. Ossabaw Island is Georgia’s third largest biggest barrier island. Eleanor “Sandy” West, sold the island to the State of Georgia in 1978, for half of what it was worth. It is protected by the Georgia Heritage Trust Act. That makes it so that it's only for education, research, and preservation. Ossabaw Island has over 5,000 years of human interaction, which makes it an ideal place to research or study oysters.

Native American Use

The Guale were a historic Native American chiefdom of Mississippian culture located along the coast of Georgia. They lived on Sapelo, St. Catherines and Ossabaw Islands.

This is a Native American shell midden on Ossabaw Island, GA. A midden, as seen in the photo, is a pile of waste and remains which have historical significance. For example, on Ossabaw Island, the Guale tribe would use oysters as a food source. As a result, many oyster shells can be found in clumps around the island.

Tabby

Tabby is a building material composed of oyster shells, lime, sand, and water. It was made by mixing lime, sand, water, and oyster shells. The lime is created by burning oyster shells, and the mixture is then poured into molds to form walls, foundations, and other structures. It was utilized from the 1800s across Georgia's barrier islands, Tabby was commonly used in the construction of structures such as slave quarters and plantation houses. Tabby can still be seen today on Ossabaw Island, Wormsloe Plantation outside Savannah, the Horton-DuBignon House on Jekyll Island, the ruins of Spalding's plantation on Sapelo Island, and many other places along the coast.

Ossabaw to Pin Point

Pin Point was settled in 1896. Freedmen came from Ossabaw, Green, and Skidaway islands. They were originally farmers. Pin Point is where they ran several coastal industries such as shrimping, oystering, and crabbing.

-B. Jones

Ossabaw Island

Hurricanes in the late 1800's forced the people farming on Ossabaw to start a new community in Savannah called Pin Point.

-M. Medhi

Pin Point

Pin Point was settled but not yet established in 1896 one year before 1897. It was formed by slaves that came from three different Islands which are Ossabaw Island, Green Island, and Skidaway Island. In 1897 they founded the Sweetfield of Eden Baptist Church in Pinpoint. It was a successor to the Hinder Me Not Church in Ossabaw. This church also served as a temporary school for the whole community.

The People

The people of Pin Point opened the Bond and Anderson Seafood house in 1900. The A.S. Varn Crab and Oyster Factory followed and was closed in 1985.

-J. Smith

Oyster Bateau

The watermen of Pin Point rowed handmade Tuck Boats, or bateaus, out into the marsh which surrounds Pin Point to make their living on the river. They constructed their own nets, collected oysters, shrimp, and blue crab, and helped the renowned canning firm A.S. Varn & Sons, which was located at Pin Point from 1926 to 1985.

Oyster Reproduction

Oysters reproduce through a process called broadcast spawning. They release millions of eggs into the water, where fertilization occurs.

Living Shorelines

Oysters provide ecosystem services when used for living shorelines. Living shorelines are made by using oyster shells to make oyster reefs that create strong barriers against waves. Living shorelines are made by providing oyster shells for oysters to attach to. When the baby oysters attach to the shell, they make a reef. The oyster reefs help stop erosion by blocking waves and holding the soil in place. Oysters also clean the water by filtering it and provide a home for marine life. Their shells form natural protection for the coast. By filtering water, they help improve water quality. Many sea creatures rely on oysters for shelter. By building oyster reefs instead of walls we can provide habitat and improve water quality.

Bagging oyster shells

The GA DNR supplied the knowledge, workspace, and materials to create living shorelines using bagged shell and wire cage methods.

Creating oyster cages

OCS students have created 27 m of living shoreline in 2024 and 2025.

The Coastal Conservation Association of Georgia has helped with memberships and advocacy for OCS students in 2024 and 2025.

Living shorelines are not only better for the environment, they are less expensive than hard armoring as well!

The Tybee Oyster Company's farm

Oyster Aquaculture

The Tybee Oyster Company and the E.L. McIntosh and Sons Oyster Company are two family-owned companies that are farming oysters on the Georgia Coast.

Tybee Oyster Company

The first company to use floating cages to farm oysters. The company was founded by a former U.S. Navy pilot Perry Solomon and an educator at the Tybee Maritime Academy Laura Solomon. They are able to produce oysters that taste good and look good for restaurants that sells oysters.

McIntosh Oysters

This is a family-owned oyster farm located in Townsend, Georgia. The McIntosh family has been working on the water for almost 50 years. They first started as crabbers until they transitioned into an oyster farm. They are a Gullah-Geechee family from Harris Neck.

-T. Moore and I. Oberhelman

McIntosh and Sons Oyster Company focuses on cultivating oysters using environmentally friendly methods. Their practices contribute to the conservation of the local marine habitat. Their oysters are known for the flavor and are served in restaurants like The Grey in Savannah.
