Fish Lice / Argulus

Fish Lice or Argulus
I was called out to a pond where all the small fish were dying.
Because it was mainly the smaller fish, I suspected parasites, specifically Argulus(fish lice) or fluke.
However, I could not see any lice on the fish, so I did a scraping and found small fish lice with a microscope. I normally treat fish lice with Dipterex (10 g / 10 000 liters) because it is cheap and very effective against lice, so I did so, however, it did not clear the fish from the lice.
After investigating, I heard that the hobbyist treated his pond with Dipterex almost every two weeks, (weak solution of 10 grams per 15 000 liters) because he had various problems with lice and Anchor worm for more than a year.
This explained the fact that I could not see any lice with the naked eye and I immediately realized that the lice became immune to the Dipterex due to the constant treatment.
I treated with Dimilin (10 grams / 10 000 liters) and it immediately cleared the fish from lice. I will do a follow up treatment to sort out the juveniles hatched after my initial treatment.
It just shows you that we have to be cautious of using weak treatments or ongoing treatments, and we should stick to the prescribed dosages.

Do you need to repeat the treatment a few times before the parasites are completely cleared out?

Two treatments a week apart is normally sufficient.

Ek het die volgende E-Pos ontvang vandag:
Ek het so pas die website ontdek in my naarstiglike soeke na raad/medisyne. Baie dankie!
Ek so pas 'n groot Asagi koi verloor. Die vis was baie traag en het bolangs gehou. By nadere ondersoek vind ek toe dat die hele koi letterlik met derduisende visluise oordek is. Ek het in jare geen nuwe toevoegings in dam geplaas nie. Waar kom hulle vandaan en in sulke groot getalle?
Ek het dadelik Dipterex toegedien. Dit was Woendag en sal 'n verdere toediening op Saterdag doen. Dit is nie te gou nie? Verloor Dipterex die sterkte of sal 'n volgende byvoeging daarvn die dosis versterk?
Luise kom gewoondlik van voels, indekte, plante en die meeste tyd deur toevoegings van nuwe vis(wat jy egter nie gedoen het nie)
Daar is 'n moontlikheid dat die luise die heeltyd daar was maar bloot nou geweldig aangeteel het as gevolg van water toestande of stres onder die vis,
Om Saterdag weer te behandel is te vinnig. Wag ten minste 5 - 7 dae in die somer en 10 dae in die winter. Dipterex(Thrichlorfon) neem langer om uit te werk in die winter)
Trichlorfon kan baie gevaarlik wees indien jy oor doseer. Die visse vrek of trek krom.
Die volwasse luise behoort na een behandeling reeds dood te wees. Jy moet nou net die wat uitbroei na jou eerste behandeling bykom.
Vir veiligheid kan jy 'n derde behandeling toedien 7 dae later.
Indien jy Dimilin het, gebruik dit eerder want dan is die korrekte dosis nie so belangrik nie.
Ek kry egter ook goeie resultate met Trichlorfon.

Baie interesante storie ek het dit as jong groente boer ook ondervind met plantluise en rooispinnekop as jou dosis te lig is dan ky jy hulle nie meer dood nie en ons het ook gereeld die soorte spuitsof afgewissel. Het n vriend wat ook dieselfde doen met sy koi dam hy kla altyd die goed is duur dan gooi hy net die helfte en oor n maand het hy weer die probleem.
Ek hoop hy lees dit

just so I know for the future,do I bypass the bio when dosing ? and how long before I run the bio again?
Subject: Re: Fish Lice / Argulus Fri Jan 18, 2013 7:57 am
Vossie, kry Dimilin by Neville, 1g / 1000L
Baie veiliger as dipterex.
Terloops, hoe gaan dit met die vis wat jy laas by my gekoop het ?
Subject: Re: Fish Lice / Argulus Fri Jan 18, 2013 2:02 pm
Dimilin will do nothing to your biofilter. It is not a "poison" and only affects creatures with an exoskeleton like Argulus. I use it around the house for flies and worms on my plants all the time.
Dipterex has in fact been taken off the market and the available stock might be toxic because it will be old, becoming toxic Dichlorfos.
