In addition to the nursery tank system, small boats and rafts made in Italy are used to gather oysters that cannot be reached by bare foot.
Under ideal laboratory conditions, an oyster can filter up to 190 L (50 US gal) of water per day. Under average conditions, mature oysters filter 11–45 L (3–12 U.S. gal). Chesapeake Bay 's once-flourishing oyster population historically filtered excess nutrients from the estuary's entire water volume every three to four days.
