http://hisz.rsoe.hu/alertmap/index2.phpState scientists will head to the Florida Panhandle this week to check on East Bay oyster beds where oystermen are reporting a die-off. Oyster season opened Oct. 1. Oystermen have reported pulling up dead oysters from beds that had been filled with large, healthy oysters at the end of the last harvest season on June 30. "We're finding very few alive," Pasco Gibson, a main supplier of the East Bay oysters, told the Pensacola News Journal. "This time of the year, we should be catching 500 to 1,000 pounds per boat a day. We're not even catching a hundred pounds." Gibson's six oyster boats are mostly idle, and some of his freelance oystermen are heading to Apalachicola to look for work. He said the meager harvests have cost him 40 percent of his income. Depending on what's killing the oysters, once they start growing back, it could take up to three years to grow them large enough to harvest, he said. "Something happened in August, and it had
to be massive because some of these beds are 10 miles apart," Gibson said of the beds scattered near the shorelines of East Bay. Scientists from the Department of Agriculture's Division of Aquaculture will check the oyster beds this week. Oyster die-offs are not unusual, said Leslie Palmer, director of the Aquaculture Division in Tallahassee.
A variety of causes could potentially be responsible, including drought, extreme heat, warmer-than-normal water temperatures, or high salinity and low oxygen in the water, she said. Diseases and parasites also can wipe out an oyster bed. Storm water runoff from Tropical Storm Lee, which hit the area Labor Day weekend, could have pushed silt over the beds, smothering the oysters, said Robert Turpin, Escambia County's marine resources manager. "That could be easily confirmed by jumping into the water and checking out the beds to see if it is silt or something else," he said. Palmer and Turpin hesitated to blame the die-off on the 2010 BP oil spill. The massive oil slick washed up on Pensacola's beaches, and pockets of submerged oil remain in Pensacola Pass. BP's Florida District spokesman Craig Savage said the oil company is working with state and federal agencies, as part of the Natural Resource Damage Assessment process, to collect hundreds of field observations and thousands of oyster samples with a goal of further understanding all the potential factors that can affect oyster production. "These results will help to guide the agencies and public in order to make informed decisions for future oyster management," he said. "We understand from federal, state, and academic scientists and fisheries experts that many factors can affect the population of oysters, which are independent of any potential impacts related to the Deepwater Horizon accident."
