The current wild oyster population in Chesapeake Bay sadly is at 1 per cent of historic levels. That’s not only bad news for the fishery, but also for water quality. A single oyster can filter as much as 50 gallons of water a day, so the vast wild oyster beds that used to thrive in Chesapeake Bay surely played a vital role in filtering the water and improving its clarity.

Though the wild harvest of Chesapeake Bay oysters continues, the practice of growing oysters in large aquaculture operations has exploded over the last five to seven years. Some of the larger operations have 5 to 6 million oysters in the water at a time, which means the busy bivalves are filtering as much as 300 million gallons of local water each day.

This video shows how oyster aquaculture is having a positive effect on Bay waters:

There are additional benefits from the practice. A percentage of the oysters are able to reproduce, casting their fertilized eggs into the surrounding waters, which aids in boosting local wild populations. Oysters also provide great habitat for small fish and other aquatic life, even when they are raised in cages.

Twenty groups, ranging from oyster farmers to research organizations, plan to boost the Chesapeake Bay’s oyster population to 10 billion by 2025, improving the Bay’s water quality in the process.

No Butt Shucking!

Curtis “Fuzzy” Wilson knows a thing or two about oysters — he’s been shucking them professionally for 35 years. The Virginia native spends the Chesapeake Bay oyster season shucking several bushels of the stubborn bivalves each day, reminding rookies to never open an oyster up from the rear, a shucking faux pas known as “butt shucking.”
