RI warns swimmers of jellyfish population explosion in 2 Charlestown ponds


Thousands of species of jellyfish that can cause a painful sting have been spotted in two salt ponds in Charlestown, according to the State Department of Environmental Management.

The state’s departments of health and environmental management released a joint statement on Wednesday informing swimmers that Atlantic sea nettle jellyfish “have been identified in large numbers by the Fisheries Division DEM marines at Ninigret and Green Hill Ponds “.

“Their bites usually cause moderate discomfort and itching,” state departments said in a press release.

Katie Rodrigue, senior marine biologist with DEM’s Marine Fisheries Division, said: “Their population in the ponds has exploded over the past month or so, probably as the water temperature has risen, and over the past week or so. , we observed thousands of them in the western section of Ninigret Pond along the East Beach side. “

Sea nettles can often be found in Rhode Island waters during the summer, most commonly in salt ponds in South County, according to the state.

People using the ponds should bring a first aid kit, along with a bottle of vinegar and anti-sting spray, according to the state.

Anyone who gets stung should remove visible tentacles with a gloved hand or plastic bag

The area should be rinsed in vinegar, anti-bite spray or salt water, depending on the condition. Do not use soft water as this can make the condition worse.

DEM is not sure why there are so many jellyfish this summer, but says the numbers are expected to decrease over the summer.
