Does any one know what these thigs on the yabbies are? 
Is salting the way to go ? how much? When I catch the yabbies they crawl around. The other day I found one of the yabbies dead and covered in them but it may have been the hot weather that finished it off. I'm wanting to add some fish to the system but thinking I need to get rid of these first.

Interesting link CC What I have in the pond are probably gilgies, Koonacs look interesting because of the size. So anyone have a clue which are best to keep/eat. Sorry for the hijack Lambs  looks like salt is the only real option.

Great Link C1 Sounds like they are Epistylis. Looks like salt bath time. |

interesting, at first I though yabbie fry, they tend to crawl all over mum too, but not to kill her

Initially hoped baby yabbies but as I found one is definitly female and has a few little tackers. She only got a mild bath so hopefully the babies will survive. |

Looks like the salt bath has done the job. 
I use a solution of 30g rock salt to 1l water for 2 minutes. This got about 3/4 of the suckers. Then followed up about 1-2 weeks later with the same for 3 minutes. I was a bit worried if the babies can handle the salt but there seems to be plenty of them swimming around now.

Lambs what do you mean for 2 minutes? Did you remove the yabbies and place them in a bath for 2 minutes? Are the parasites only on the yabbies, and not in the water too? Is there any reason you didn't just salt the entire tank? |

KP Took the yabbies out one at a time, dropped them in the salt bath for 2/3 minutes then back into the tank. I think there were still some parasites left in the water so the second time I did it they went into a different tank, but still part of the same system. far less salt for one litre and the plants did not have to suffer |

ok fair enough. How do you intend to remove the parasites from the tank the yabbies were taken from? starve them by denying yabbies, and put a sock over the pipes to stop them moving from tank to tank? Could be you'll have to repeat this process a few times, like lice they may leave behind eggs yet to hatch that aren't killed by the salt. You'll get em all in the end I'm sure

Im trying to starve them and hope they dont move between the tanks. good idea with the sock, the drain is an over flow so hoping the eggs will sink. next option would be to get rid of the yabbies (only 4 left and some babies) and replace them with fish or salt the whole system. |

I read somewhere on here that yabbies have a really high salt tolerence. A quick google: "How much salinity can yabbies take? Yabbies can survive up to about half seawater (17000 mg/L), but as a group they become unsociable over 12000 mg/L and growth slows over 6000 mg/L. Research is needed on Yabby eggs and hatched young, which may be less tolerant. Salinity tolerance is not really an issue because yabbies do well, and you can trap them, in muddy dams. Muddy dams will usually go clear over about 1000 mg/L salinity. " From http://www.fish.wa.gov.au/docs/aq/aq001 ... 4.php?0309 |
