“Can Suminoe Oysters Save Chesapeake Bay?” by Nieman & Liu Page 

Annapolis, January 2008 “If you don’t do the right thing, we will take matters into our own hands.”

State Senator Ben Fisher hung up the phone slowly. " at was one of his constituents, one of the many he had heard from that day, each one angrier than the last it seemed. His was the swing vote on the Assembly bill funding the full-scale introduction of sterile Suminoe oysters to the Maryland side of the Chesapeake Bay. " e bill was an attempt to try to off -set the eff ects of declining populations of native oysters in the bay, the result of habitat degradation, over-harvesting, and disease. Introducing the Suminoe oysters would be an expensive and risky undertaking, but there were costs—both environmental and economic—of doing nothing, too.

Environmentalists were divided, “clean” versus “pristine.” Some demanded widespread seeding of the imported oysters to deal with worsening water quality that was wiping out aquatic life in the bay. Others warned that this could be a bigger disaster than kudzu. Test introductions in Virginia had been limited and closely monitored—and so far so good. But scientists warned that a few oysters would be fertile and might proliferate, forcing out the last of the Eastern oysters or interbreeding with the native species - bringing who knew what changes to the already damaged ecosystem?

Ben gazed out his offi ce window. “CLEAR THE BAY!” said one of the banners that blocked his view of the sailboats in the harbor. “DON’T TINKER WITH A NATIONAL TREASURE!” warned another.

Business interests held all sorts of positions. “We’d rather see those tax dollars go into developing infrastructure for high-end development,” a major developer with plans for summer homes, condos and retail shops had emailed Ben. “Do you know what that land is worth under those broken-down, abandoned fi shing shacks?” He didn’t need to add that he put a lot of money into political campaigns.

" e owner of a fi sh market had called earlier in the day, worried that the oysters, whether native or otherwise, might not be fi t for eating as a result of all the pollution they fi ltered from the water. She had few oysters to sell now—would the new ones appeal to customers?

" e Delmarva Peninsula poultry producers didn’t want any more controls on the nutrient load entering the bay. " ey felt there were too many controls as it was, and warned that more controls would hamper their operations. " ey were all in favor of the oysters as a solution. So were the charter-boat owners who wanted clear water for the rockfi sh.

The commercial fishing industry wanted the oysters too, and now. Boats were idled and processing plants were handling trucked-in Louisiana oysters. The biggest plant in Ben’s district said it would close this year if things didn’t change. These new oysters grew three times as fast, they said. It wasn’t too late to save an industry.

On the other hand, the State of North Carolina was threatening a lawsuit, fearful that the nonnative oysters would spread down the coast and aff ect their beds. " ey cited the destructive virus brought in by oyster introductions decades ago.

And many of Ben’s constituents were in an uproar over the expense that Marylanders would bear for the oyster option—or the alternative. Towns and cities didn’t want to spend money to upgrade their sewer systems when so much pollution came from out-of-state.

Even within the Senator’s own family there was division. His father, who had started tonging oysters when he was a boy, said it was time to let the old ways go, that fi shing was no way to make a living these days. Spend the money elsewhere. His daughter, a member of a cultural preservation group, pleaded: “We need to preserve the watermen culture. We need the oysters.”

And now this dramatic phone call—desperate people threatening to take the matter into their own hands and dump imported oysters—nonsterile ones that could reproduce and spread—into the bay to restore the beds. " e debate had dragged on too long, they said. A decision had to be made.

Senator Ben Fisher left his offi ce and walked down the echoing hall to the Assembly chamber, where he would have to cast his vote.

Questions . Who is being aff ected by this decision and how? . If the decision is made to introduce the Suminoe oysters, what might be the long-term eff ects on

the environment, the communities, the people? . Any choice implies other lost opportunities. In what alternative ways might this money be spent

to deal with the Chesapeake Bay’s problems and serve constituents? . What might this region look like in  years if nothing is done? . What should Senator Ben Fisher do?
