During thelohanellosis, a disease of carp fingerlings caused by Thelohanellus nikolskii, it is possible to differentiate six stages which may be described clinically and histologically using light and electron microscopy. Characteristic developmental stages were manifested during the first years of appearance of this most widely spread parasitic fish disease, while in the following years, the appearance and stages of the disease could not be resolved as regularily. This paper makes a comparison between the clinical manifestations and the results obtained using the classic histological methods (light microscopy and transparent electron microscopy). Since the mass appearance of the disease, up to date, its developmental cycle has changed considerably.
