Six years after the oyster industry in Apalachicola Bay collapsed, scientists still don’t agree on what happened.

When Robert Livingston studied Florida’s Apalachicola Bay and River in the 1970s, he marveled at the ecosystem’s health. The bay produced a rich bounty of oysters, shrimp, fish, and crabs. Those animals, in turn, supported a thriving fishing community and seafood industry. But since then, the bay has declined. During a 2012 drought, the oyster fishery collapsed—and has not recovered. In the past, the ecosystem “was like a symphony orchestra,” says Livingston, an aquatic ecologist at Florida State University in Tallahassee. “Now it is not. It is dysfunctional.” >click to read< 09:35
