Argulus medication in Fresh Water Ponds of Catla Catla & Labeo Rohita
11/15/16 Argulus
5/7/14 Koi infected with Lernaea 4/26/10 Outside pond fish... possible Lernaeid 10/21/05 Hi, this is our first time on your web-site, and we have a question. We have an outdoor fish pond with 4th generation goldfish! Today I noticed something on one of the fish. It is gold in color, protruding ( from under his skin)? or sticking out of his skin, I can't really tell. It looks like a thick wire sticking out. He doesn't look or act different, eating as normal. I didn't see anything like this on the other five fish. Do you think this is some sort of parasite? <Mmm, possibly... Lernaea... "Anchorworm"...> What would you suggest we do? <Mmm... place this/these terms on the WWM, general search engines... read... If this is the cause/parasite, removing the adults by tweezing, inspecting all fishes, using a organophosphate to kill intermediates is suggested. Bob Fenner> Thanks Donna DTHP use, marine, dips 7/7/05 Hello, Crew, It's me, dum-dum, again. Okay, so I was reading about DTHP for the treatment of various and sundry parasites and other general nastiness. Recalling what I'd read already about QT, freshwater dips, Methylene blue, and so forth, I was wondering if anyone had ever established a protocol of a DTHP dip as a precautionary step prior to introducing species to the main tank. Perhaps during the last four or so days of QT? <Some wholesale outfits have used this, other organophosphates to rid fishes of "worms" and crustacean fauna (parasitic and otherwise) en-route... I would not, do not encourage home-hobbyists to do this. Too much likelihood of damage, toxicity to the livestock and themselves. Bob Fenner> Joe Kraska
Possible anchor worms and CopperSafe First, I'd like to tell you that your site is fantastic, the best fish site I've come across, and I've looked at a few. I think I'm having a problem with anchor worm. <Sometimes difficult to eradicate once established.> I have three tanks-one 20 gallon with four (used to be six) very large ex-feeder goldfish which is always cloudy, yet the ammonia and nitrites/ates are nil and the pH is 6.5 or so. One tank is 55gallons with two big Koi, three channel cats (two big), and seven goldfish of varying size (two of which came from the 20 g tank). The other tank is 15 gallons with three very small fancy goldfish (the ones with the big bellies and the forked tail fin) and a Pleco which also came from the 20 g tank. Two days ago, I noticed a goldfish in the 55g had a bump on his skin with a white wormy thing sticking out. <Does sound like a Lernaeid...> Then I saw that a goldfish in the 20g tank had two red raised spots with white stuff on him (the scales were missing from the spots) and one with a veiltail has red near the ends of his tail fin. The Pleco in the 15g has had his fins clamped and won't eat very much, and I think I saw some white stuff on his mouth. He doesn't come out much, it's hard to see what's going on. These tanks are all well established and have the same water chem, i.e. no ammonia, no nitrates, and 6.5 or so pH. The water in the 55g is crystal clear, and a little bit cloudy in the 15g. They're well established, I do water changes every week, and I don't understand why they should all of a sudden all get sick. The transferred fish have been in their new tanks for at least 2 1/2 weeks. I started using CopperSafe, and it made all these little red worms come out in the 20g tank, and white worms in the other 2. <The copper won't "get" the intermediate stages... you'll poison the fish stock before the treatment can be completed...> No noticed improvement in the fishes' conditions. How long does this stuff take to work? What can I expect? Do I have to treat for secondary bacterial infection? <Good questions. Please read here: http://www.wetwebmedia.com/PondSubWebIndex/contrpdparasit.htm You need to seek out a source of this pesticide, follow the directions that come with it, or the ones posted here> I apologize for the length, but I really don't want my fish to die and you really seem to know what you're doing. Thanks in advance. Pati <No worries. Do contact me if this is unclear, incomplete. This is an easy problem to fix, given the active ingredient... and cautious use. Bob Fenner> DTHP Dear Robert, Read your web article about DTHP. Where can I get this material <Is sold as such, by itself and in concert with other materials for pet-fish use in various products... mainly labeled as Masoten, Dylox... see a LFS re if you're looking to treat small volumes. We can chat if this is for thousands, much more volume.> and have you heard of it being used against Gyrodactylus? <Yes... you can see this through a literature search... the most recent work of Ed Noga, Nelson Herwig... Bob Fenner> Steve What's in Fluke Tabs? Hi Chuck! I bought the Fluke tabs. Do you know what are the active ingredients? It's not written on the product. Thanks! Dominique <The active ingredients are Mebendazole and Trichlorfon.-Chuck> Can't Get the Right Medication Hi Chuck, I really appreciate your replies on this. I get what you're saying about how nasty these things are to get rid of. I'm in the UK so Fluke tabs and 'Clout' aren't available here as far as I know. Have you any idea what's in them? < To treat these worms the Fluke tabs have Trichlorofon and I am not sure what the ingredients are in Clout. The next step I would try would be copper. Be very careful, usually the dosage required to kill parasite is very close to the same dosage required to kill a fish. There are suppose to be some newer less toxic forms on the market here in the US but I have not personally used them.-Chuck> Gill & Skin Fluke Treatments in the UK Dear Robert Hi, I'm Martin from Cornwall in England. I've been keeping Koi for 8 years and have a gas heated 6000 Imp gallon pool in my back garden. For me 2001 was a terrible year, I have lost 6 nice carp because of ulcerated wounds caused by a very persistent infestation of gill and skin flukes. These flukes seem resistant to treatments like potassium permanganate and chloromin T. The only thing that seems to control them properly is organophosphates, in the form of a product called 'Metosan'. <Yes... aka many other names. My standard "pitch" on DTHP archived here: http://www.wetwebmedia.com/pndparasitcont.htm and the associated FAQs... in fact, just had a query today from a pond-culture scientist in India, stored here: http://www.wetwebmedia.com/dailyq&a.htm re the use of this economic poison and others for treating Argulus on cyprinids...> This type of product is difficult to get hold of in the UK. do you know of any companies in the UK or USA who would be able to supply these types of products by mail order. <Mmm, no, don't... but would ask re this compound under the various names cited in the article above... and Dimilin... of friends, associates at TMC: http://www.wetwebmedia.com/tmcpropc.htm I strongly suspect they will know where to refer you> I have been able to get my hands on enough Metosan for one treatment, the are looking better than they have looked since last May. But I now need to repeat the treatment to kill the latest juveniles to have hatched out! <Yes... three treatments three days apart likely...> Hoping you will be able to help and look forward to hearing from you. Thanks Martin Yardley <Cheers my friend. Bob Fenner> Argulus (food, pondfish culture, disease
control) Dear D. Fenner Robert, I am a veterinarian working in
State Bank of India biggest Bank financing agricultural and
Aquacultural schemes in India. 2.Fish farmers raise Major Indian Carps
(Catla catla, Labeo rohita etc.,) in big freshwater ponds with an
extent of 10 acres to 100 acres Water spread area. The culture period
is 8 - 10 months -Weight 1-2 Kg each. To minimize the feed cost and
cost of production, our fish farmers are using heavy doses of dried
poultry droppings organic manure) to fertilize the pond waters and for
production of Phyto & Zoo plankton. The demerits of this practice
is too much infection with Argulus (sea lice). As a result, farmers are
using pesticides Viz., Deltamethrin (Butox), Dichlorovos (Nuvon) which
are retarding the growth of the fish. Please enlighten me on the
following two points: a. whether any effective biological control
against Argulus is available? <None that is practical as fast as
I'm aware... most practices are as yours, involving economic
poisons in the class of organophosphates (acetylcholinesterase
inhibitors)... as these crustacean parasites metabolisms are similar to
arthropod pests> b. whether Diflubenzuron/lufenuron (Dimilin) can be
mixed with the above chemicals to decrease the dosage and frequency of
chemical application? <Yes, once again, as far as I'm aware.
Dimilin supplanted the use of DTHP (Neguvon, Dylox...):
http://www.wetwebmedia.com/pndparasitcont.htm in ornamental pond use
(on cyprinids like Cyprinus carpio (Koi carp, Nishikigoi) and Carassius
goeblio (goldfish) in the U.S. some years ago. Should be miscible.>
Please send technical information on the life cycle and control methods
in big fish ponds. <I don't have ready access to such, don't
even know if this is part of the literature... would have to search as
you are> 3.Please help me in the upliftment of fish farmers. <I
will gladly assist you in what ways I can. Understand that though my
academic background is in fisheries, I have spent the last decades in
ornamental aquatics... not production. Bob Fenner> Thanking you.
