Savannah scientists continue study of black gill in shrimp

As the Research Vessel Savannah moved slowly along Georgia’s coast in early October, Wynn Gale calmly arranged about a dozen shrimp on a table inside one of the boat’s laboratories. He inspected each specimen for dark gill coloration, and then he took a photo of the shrimp on his smartphone. Black gill, named because of a telltale dark coloration on shrimps’ gills, is caused by a microscopic parasite. Scientists have determined that the parasite is a ciliate, a single-cell organism, but have yet to identify the specific type. Scientists say shrimp suffering from black gill are safe for humans to eat. click here to read the story 08:53

Research reveals black gill kills shrimp

A disease that’s crippling the shrimp industry may be doing more damage than originally thought. Researchers in our region have made new findings about black gill disease, this as the industry is still rebounding from the worst shrimp harvest in Georgia history. The latest findings from scientists with the University of Georgia’s Skidaway Institute of Oceanography is unsettling. It reveals black gill may continue to push the shrimp industry into the red. “We’ve observed in controlled laboratory situations, mortality events, death of shrimp, that could only be caused by them having black gill. We’ve removed all other predators, uh, we have control groups where they don’t die, so it’s not something else in the water, but the ones with the black gill are dying.” said Dr. Marc Frischer with the UGA Skidaway Institute of Oceanography.

Study aims to help Ga. and S.C. shrimpers weather black gill

There’s no quick fix for black gill, a disease that affects shrimp from Florida to North Carolina. But as regulators and scientists collaborate with fishermen to work on the problem, they’ve already boosted an iconic coastal tradition. “Generally, we’re seen as the bad guys, the ones that kill the turtles and rape the ocean,” said Micah LaRoche, a third generation shrimper from Wadmalaw Island. “I’m anything but that. I have grandchildren looking to get into the business. As far as conservationists go you’ll never find another one like me.” Read the rest here 07:34

South Carolina and Georgia shrimpers brace for black gill

While Lowcountry shrimpers have seen little of their catch infected with black gill disease this year, scientists say it’s only a matter of time. The infection, which causes dark spots to appear on the midsection of shrimp, is not dangerous to humans. It remains somewhat of a mystery to scientists and shrimpers, but some of them blame it for reduced shrimp population in recent years. Charles Gay of Gay Fish Company on St. Helena Island said his shrimpers began seeing black gill this week. Read the rest here 13:24
