Jelly babies booming

THE River Derwent has been invaded by jellyfish _ thanks to a spawning boom by the colourful creatures.
Tasmanian Museum and Art Gallery curator of invertebrate zoology Liz Turner said the event was not unusual and most of the invaders were of the Aurelia aurita species but the numbers were bigger than normal.
"There are several sizes among the masses, which suggests we are having a boom spawning," she said.
"This happens every now and then in the River Derwent, though to my knowledge it is the first time since 1999 that there have been such numbers."
While not as toxic as its tropical cousins, the species can cause a painful sting.
It does not have a painful sting as a juvenile but caution is advised with mature jellyfish. Examples of the species are regularly washed up on beaches during summer and have been seen in the river and docks in recent weeks.
In three months they can grow from 10c-sized specimens to saucer-sized.
"Some of the stings can be uncomfortable and some people can have terrible allergic reactions," said Recreational Fishing Tasmania president Don Paton.
It is expected they will stay around sheltered waters most of the summer.
There are other less common jellyfish in Tasmanian waters, including the lion's mane jellyfish, Cyanea capillata, which has a more painful sting. It is commonly called the brown jellyfish and has also been spotted in larger numbers in recent weeks.
They can be distinguished from other jellyfish by their dark, beer-bottle colour.
Mrs Turner said the bluebottles in Tasmania, also brought in by winds and currents during summer, were nasty, though less harmful than the tropical version.
TREATING STINGS
Run under cold water, preferrably sea water, and apply an ice pack.
For bluebottle stings, run hot water over the area, then cold water and then apply an ice pack.
