Guam EPA to list jellyfish calendar in weekly Beach Advisory

09 September 2013

Residents asked to report jellyfish sightings

The Guam Environmental Protection Agency (Guam EPA) will begin reporting the probability jellyfish will be near Guam’s shores in the weekly Beach Report.

Although they can be present at any time, jellyfish are usually reported near Guam’s shores nine to 11 days after a full moon. In addition to jellyfish, Guam can also have Pacific Man ‘o War blow near shore during periods of strong offshore wind. Both jellyfish and Pacific Man ‘o War can cause painful stings.

Every week, the Beach Report will include a Jellyfish Calendar box that outlines how likely jellyfish are to be near Guam’s shores. The box also includes the dates thatjellyfish are expected to appear.

“The ocean is a beautiful ecosystem but it can be dangerous if approached without knowledge and respect,” said Guam EPA Administrator Eric M. Palacios. “We hope to keep the public informed about bacteria levels and the possibility of jellyfish so everyone can enjoy the beach safely.”

Residents are also asked to report any sightings of jellyfish or Pacific Man o’War to Guam EPA via the agency’s website, Facebook or by calling 300-4751/52/53. Residents can also report sightings to the Guam Department of Agriculture at 735-3955/6 or 787-5853.

The upcoming dates jellyfish are expected include Sept. 29 through Oct. 1, Oct. 29 through 31, November 28 through 30 and Dec. 27 through Dec. 29.
