[Cnidaria] cleaning jellyfish mucus from nets

[Browne, Joanna]

Dear Wyatt,
 
Thanks for your info, I'll give the vinegar a try.  I'm working on
Catostylus mosaicus, and spend a day on the water so by the time I get
back to rinse the net, the mucus has taken hold!  I go out every 6 weeks
on Port Phillip Bay and the net has lasted 8 trips now so it's not doing
too bad considering all the mucus on Catostylus!   I've also been
working on Cassiopea (and an assortment of hydrozoans and ctenophores)
up in Queensland, but I've caught them by hand (well, gloved hand!) or
zip lock bag so no net issues!
 
Thanks for the advice,

Cheers
Jo

	Hey Joanna,
	We rinse out nets immediately after each use, usually from
straining a moon jelly to feed out to other jellies. We give them a
pretty thourough blast with a hose on "shower" setting. This works for
us, however if it still gives you trouble, perhaps try adding a little
vinegar/acetic acid? Or a light bleaching shoud do the trick. Pretty
sure I know the mucus blockage you are describing and that usually only
happens to us when we don't rinse a net immediately.
	 
	Which mucusy species are you studying?

	Dear all,
	 
	I am a PhD student studying jellyfish parasites.  My sampling
net, a hand net with a fine 100 micron mesh, is becoming increasingly
blocked by jellyfish mucus.  I clean it each time I use it with a high
pressure hose but it is not too effective.  Does anyone have an
alternative cleaning method, such as soaking, or a chemical to remove
the jelly mucus?
	 
	Thanks for your help
	Jo
