I have found this organism on the Cyprinus carpio skin. The fish was in adult stage. It looks like to me as a some kind of nematod, but I cannot be sure!
Thanks,
Zlatko
Dear Zlatko:
unfortunately I cannot help with determining your "winding organism" but would like to point you to:
Sepulveda, M. S., Kinsella, J. M. Helminth Collection and Identification from Wildlife. J. Vis. Exp. (82), e51000, doi:10.3791/51000 (2013).(including a video): see

Perhaps you will find help from the authors of the study/article.
Best of luck and wishes, WM.

Dear mr. Wolfgang, thanks for your guides. I think this helmith could be from the genus Strongyloides, but it something strange because Strongyloides are most common as a parasites of the primates and humans, but very rare in fish.
Dear (Mr. ) Zlatko, thank you for your additional information. I shall be with the thread until the secret has been elucidated (:-)) Unfortunately I am not quite familiar with that parasites, neither in fish nor in other primates or human...but find the matter interesting. Just as a question aside (not necessarily urgent for reply): which method of documentation in a video you used? Good luck, best wishes for now (and hopefully there will be another expert in the field of paraistes chiming in... yours sincerely, Wolfgang (my first name.... I am really an informal person (:-))
Zlatko, I tried to search...and found the following (guessing that you don't deal with aquarium fishes...): Capillostrongyloides ancystri sp (new parasite in aquariumm fishes in Europe), Article with sketch see: folia.paru.cas.cz/savepdfs/fol/1987/02/09.pdf
Best regards, WM
Das ist sehr gut, ich werde dieses Artikel ansehen, aber ich denke das ist Strongyloides. Ich arbeite jetzt auf dem Sava Fluss und dort gibt es viele Verschmutzigung aus der Kanalisation. In vorlaufige Ergebnisse von meine Forschung habe ich viele verschiedene Forme von die Parasiten: Protozoa, Monogenea, Digenea, Cestodes, Acantocephala, Crustacea usw.
Lieber Herr Kollege Zlatko Nedic....vielen Dank...auch für die Antwort in Deutsch.
(Dear Zlatko, thank you for your kind info on your work and translated to German too!) I wish your work is/will become successful!
Best regards, Herzliche Gruesse, WM
I recomend to you the fixation of the worm on a slide and proceed with the observation of the crown or "head" counting the spicules for the taxonomic identification. Regards, Jose. P.D. This fish is not common in South America but is under attack of parasites in aquaries.
I would say that it is a juvenile nematode. I was hoping you could provide more information. Is this a wild or farmed/aquaria fish? Did you observe any unique features on the nematode? Any other details regarding the fish or parasite that can't be seen from the posted video?
Dear prof. Frederick, thanks for your answer, and thanks dr. Pizarro too. Aformentioned fish was wild fish, species Cyprinus carpio. I study parasites on fish individuals in Bosnian waters and did not observe any features of located unknown individuals. I have found a lot of similar individuals on the other fishes from cyprinid family. The question is why? Why are these individuals on the fish skin and behave their self like an ectoparasites? The reason for that condition could be a lot of fecal materies in the waters. The Origin of these materies could be fecal products of the human!
I haven't forgotten your question! My apologies, I've been quite swamped with meetings, manuscripts, and data analysis. I'll be taking a look over today, if it's not too late :)
Looking back on the video and knowing that they are infecting the external surfaces...I wonder if it could be leeches you're observing....
Looks like a larval nematode. Fix it in hot ethanol and clear with lactophenol and make a permanent slide to establish its identity.
