Oyster Filtration

In this striking visualization we see two tanks filled with water from the Honga River, an estuary of the Chesapeake Bay.  The tank on the right also contains oysters.  Over the course of 2 hours those oysters filtered all of the algae out of the water.  Typically a single oyster can filter up to 2 gallons of water an hour.

Oyster Filtration – Time-lapse video demonstrating oyster filtration.  An adult oyster is capable of filtering 20 to 50 gallons of water per day.  It is estimated that historic populations of oyster in the Chesapeake Bay were capable of filtering the entire volume of the bay in less than 5 days!
