Inmates Make Oyster Cages, Plant Hope for a Cleaner Bay
Oct. 9, 2014 - The state of Maryland is running an innovative oyster gardening program to help improve the water quality of the Chesapeake Bay and bring back the bay's natural filters. Using baby oysters (called spat) provided by the University of Maryland and cages built by inmates at a Maryland prison, volunteers tend to the oysters for a year. The full-grown oysters are
then harvested and delivered to sanctuary reefs in the Chesapeake,
where they will start the filtering process and provide habitat for
other bay species.

DON MERITT, DIRECTOR – OYSTER RESTORATION AT HORN POINT
LABORATORY, UNIVERSITY OF MARYLAND:
The bay has gotten a lot dirtier. There’s a lot more algae blooms and a lot
more sedimentation. I’ve seen the bay
when I was a teenager. In the summer the
bay it would be very common to have visibility be 12-15 feet, even 25-30 feet
in some places. Now you are lucky if you
can see down a foot.
As we learn more about what causes our bay to degrade ,we’re
going to learn more about what will fix it.
And I think that’s what our oyster program here is helping to do.
[MARK LOUZON SOT] So all these shells are full of barnacle
but it is also good for the spat as well.
So, Chris do you want to be the Counter-in-Chief? (Laughs)
DON MERITT, DIRECTOR – OYSTER RESTORATION AT HORN POINT
LABORATORY, UNIVERSITY OF MARYLAND:
Maryland Department of Natural Resources has a really
effective oyster gardening program called “Marylanders Grows Oysters.” And what they do is they recruit waterfront
property owners that have piers or something and they provide them with baby
oysters, or oyster spat, and they hold them in trays under their pier for a
year and the oysters grow. And the
citizens go out and take care of those.
And once a year Maryland DNR picks those oysters up, takes them to a
sanctuary area, puts them on the bottom where they will create this wonderful
diverse oyster ecosystem.
SUZANNE BRICKER, MANAGER - MANAGER - NATIONAL ESTUARINE EUTROPHICATION ASSESSMENT,
NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION:
The main issue in the Potomac River estuary in my opinion is
nutrients. That means high algae blooms floating
on the water. That sinks and causes
low-dissolved oxygen which we also call hypoxia or anoxia.
So we’re hoping that with our research on the potential for
aquaculture of oysters to reduce the systems of water quality health by taken
them out water body through filtration.
DON MERITT, DIRECTOR – OYSTER RESTORATION AT HORN POINT
LABORATORY, UNIVERSITY OF MARYLAND:
Our oyster hatchery here, like most other hatcheries, we can
control the temperature here and we can get oysters to be ready to spawn pretty
much whenever want them to. Once they
spawn, we collect the eggs, we fertilize the egg, we grow the larvae in large
tanks. And it takes 2-4 weeks from the
time the eggs are spawned and turn from a swimming larvae into a spat.
Those spat have to go into some kind of structure that is
held under the pier. Maryland has a
cooperative program with the inmates in Hagerstown at one of the prisons and
they actually provide the manpower to build the cages.
JEFFREY STUART, INMATE, MARYLAND CORRECTIONAL INSTITUTION:
I’ve been building oyster cages to replenish the bay. So we come in here and put them
together. We do approximately 2 piles a
day, about a 130 cages.
CHESTER CONLEY, INMATE, MARYLAND CORRECTIONAL INSTITUTION:
We have several guys working on them. They have different stages. When they get bored of doing one area, we
switch them to another area. That way
nobody gets monotonous about their own job, you know. So it goes pretty smoothly, really.
GREG HAUPT, REGIONAL MANAGER – WEST DIVISION, MARYLAND
CORRECTIONAL ENTERPRISES:
What is does is it provides a lot of our inmates for
valuable work and a chance to contribute to society. So we think we’re doing that. We make these for the [Maryland] Department
of Natural Resources. They pay us—our inmates—for working on all of
these. And that money goes back to pay
the inmates , pay our salaries, pay our trucks that deliver them. We’re totally self-supporting.
MARK LOUZON, OYSTER GARDENER:
Originally it was going to be four cages. I said we can take more than that. Eight, then it grew to ten. So we’ve run ten cages for the past two
years. It’s purely volunteer so the
biggest thing for us is we have to make sure we’re down here every two weeks
and do the oyster shaking.
We love the area and we know the Chesapeake Bay is
challenged with keeping water quality up.
We know the oysters are challenged because they dropped off so much over
the years. And we thought this was our
way of maybe giving back a little bit.
DON MERITT, DIRECTOR
– OYSTER RESTORATION AT HORN POINT LABORATORY, UNIVERSITY OF MARYLAND:
It’s not just the oysters that are filtering. It’s the community that the oyster themselves generate. Lot of things come and live around
oysters. Many of them are also filter
feeders. So when we talk about the
filtering capacity of oysters, what we really should be talking about is the
filter capacity of the community that develops because we put oysters out
there.
