Tangier Island
Farmed in floating cages off an eroding Chesapeake island of 450 people. Investors and local watermen started it; ice destroyed 600,000 oysters before the first harvest.
Vibrio Moves North
In 2004 raw oysters from Alaska made cruise passengers ill, 1,000 km north of any oyster previously linked to the illness. Warming water is redrawing where raw oysters carry risk.
The Oyster That Escaped
Farmers thought northern Europe was too cold for Pacific oysters to breed. Warm summers proved them wrong, and wild reefs now run from the Netherlands to Norway.
A More Acidic Ocean, a Different Oyster
Acidified upwelling already kills larvae in Pacific Northwest hatcheries. In experiments it also leaves adult oysters with thinner shells and less carbohydrate, and so less body.
The 2021 Heat Dome and Oysters
Record heat, the lowest tides of the year and midday exposure: how the 2021 heat dome cooked shellfish on Salish Sea beaches, and what it revealed about triploids.
The Hydrogen Project Named After an Oyster
An EU consortium set out to make hydrogen from seawater at the foot of offshore wind turbines, and named the project OYSTER. It ended in 2025 before its trial ran.
Oysters and Coastal Ecosystems
Oysters filter, remove nitrogen and build reef. Before overharvest, Chesapeake oysters could filter the whole Bay in about three days. Today it takes most of a year.
