The collection of Irukandji jellyfish from onshore and offshore coastal Queensland for taxonomy and toxinology research (C6.3)
Task leader:
Task associate: NA.
Irukandji jellyfish have been caught around Cairns for the past 6 years
and specimens sent to Australian Venom Research Unit (AVRU) in Melbourne
for venom analysis. In the past three seasons the approximate numbers
caught have been 200, 2, 1800 respectively. The analysis of venom extracted
from these jellyfish has improved our understanding of the underlying
causes of this potentially deadly marine sting. However further study
of the venom and the way in which it causes injury is essential for a
full understanding of the syndrome.
The Surf LifeSaving Association (SLSA) will continue to collect culprit
jellyfish using qualified personnel in appropriate safety gear. Our collection
method was used in 2003 and resulted in a zero sting rate. We will also
acquire specimens from the Whitsunday region. Cental Queensland Rescue
Helicopters will transport the catcher to the relevant offshore islands
when the helicopter is called out on Medivac. The catcher will then remain
behind and, following the same protocol, net the Irukandji. Lifeguards
in Townsville and Magnetic Island are also being trained to net safely
for Irukandji. The specimens will be snap frozen for venom extraction
in Melbourne. Additional samples will be kept for taxonomic and DNA studies.
Objectives
This research aims to collect and identify suspected and definite
Irukandji jellyfish for taxonomic and toxinological research purposes.
The SLSA proposes to continue to have qualified personnel drag for Irukandji
whilst wearing updated marine stinger suits and following the same protocol
that has proven effective in 2003.
The aim is to catch Irukandji jellyfish in the northern Cairns beaches,
offshore Cairns and Port Douglas, Magnetic Island and Townsville, and
the Whitsunday Islands. These specimens are necessary for Irukandji venom
research at the AVRU, and elsewhere. Drags will only be conducted after
someone has been stung, as this method has been found most cost-effective
in the past.
