Oyster lovers will shell out more for the marine delicacy this fall, as freshwater runoff from Hurricane Harvey's historic floods killed virtually all of the bivalves in the prolific seabeds of Galveston Bay.
The storm was the latest setback to a multimillion-dollar commercial fishing and seafood-processing industry that appeared poised to finally rebound from floods, including two devastating tropical weather systems, and an extended drought in less than a decade. Shrimpers, crabbers and other fishermen who work the bay also will feel an impact.
But it's most lethal in the case of the oysters, as Harvey-spawned rains and rainwater runoff drove down the bay's salinity to fatal levels. Salinity levels of 12 to 30 parts per thousand are ideal for a healthy oyster harvest in Galveston Bay, which researchers say is the nation's most bountiful. Yet preliminary tests performed by commercial fishers on Tuesday revealed salinity levels at 0 to 5 parts per thousand – and excessive water continues to drain into the bay.
