About the species
The Eastern oyster is treasured as food by humans and other species. They are habitat for fish, crabs, and other aquatic life—and because as filter feeders, they help filter the water. Centuries ago, they were plentiful. In some places, reefs were so big that ships had to navigate around them. Since then, in many areas, the populations have dwindled to just a few percent of what they once were. This is due to disease, overharvesting, habitat loss, and poor water quality.
But people, including NOAA scientists, are working hard to rebuild oyster populations. Many people are growing oysters for people to eat. Oyster aquaculture—farming of these tasty shellfish—is a growing industry. And NOAA and our partners are working to restore the healthy oyster reefs that so many other species rely on for habitat. Recreational anglers target healthy reefs for fishing opportunities, too. In the Chesapeake Bay, for example, NOAA and partners are involved in the world’s largest oyster restoration effort . There, they have restored nearly 1,400 acres of oyster reef—that's more than 2 square miles, or 1,055 football fields.

Appearance
Eastern oysters are of the shellfish family. Like mussels, clams and scallops they are bivalve mollusks, and have a hinged shell. They have fast growth rates and high reproduction rates. Each female Eastern oyster can product over 100 million eggs during one spawning event.
Adult Eastern oysters are sessile—they stay in one place—and inhabit both intertidal and subtidal areas. They first mature as males, and then later develop female reproductive capabilities.
Where They Live Range Eastern oysters are found along eastern North America from the Gulf of St. Lawrence to the Gulf of America (formerly Gulf of Mexico). They are found in the middle and lower Chesapeake Bay and its rivers. They are the only species of oyster native to this region.
Habitat Eastern oysters live in brackish and salty waters from 8 to 35 feet deep. In some warmer areas, they are able to live in the intertidal zone. They attach to firm bottom areas, and to each other, to grow into reefs. These reefs provide habitat for fish, crabs, invertebrates, macrofauna, and birds.

Habitat
Are Eastern Oysters Sustainable? U.S. farmed Eastern oysters are a smart seafood choice because they are sustainably grown and harvested under U.S. state and federal regulations.
Ocean City & Mid-Atlantic context
From Ocean City, Maryland, use this Eastern Oyster profile as NOAA Mid-Atlantic directory context—not a promise you will meet the species on every charter.
Always verify current Maryland and federal size, season, and bag rules for your exact date and coordinates before you keep any catch.

What charter to book from Ocean City
Eastern Oyster is more of a bay, inshore, or specialty harvest story than a typical OC six-pack trolling day—match the trip type to the animal.
