THE blue blubbers that plagued Hervey Bay's beaches last summer look set to return.
Surf Life Saving Queensland regional manager for Wide Bay Capricorn Craig Holden said the blue blubber, also known as the catostylus jellyfish, was not life-threatening - but it could give a nasty sting.
"I wouldn't exactly say they were a major concern but swimmers need to be aware," Mr Holden said.
"Last year they reached almost plague proportions, we're hoping there won't be quite as many this year.
"The water had been pretty clear, up until about a week ago."
Mr Holden said the best treatment for the blubber's stings was flushing with warm water.
"After that, if it's still hurting, use some ice to minimise the pain," he said.
"Jelly numbers are monitored as part of our daily risk management strategy when-ever we patrol the beach."
