| Abstract | ||||
| The purpose of this article is obtaining information about Lernaea species that infects carp fish in the fish farms of Tashkent and Fergana regions of Uzbekistan. Of the 240 carp samples examined, 76 were found to be infected with Lernaea cyprinacea, with the highest infection rate being 40% in the Tashkent region. The number of parasites is 1 - 8 copies. The morphology of the parasite, as a result of experimental studies, the average length of parasite females is 8.86 mm the anchor width is 2.35 mm. The morphological and morphometrical description are almost consistent with the description of L. cyprinacea in previous studies, which confirms that it is L. cyprinacea. Molecular identification 18S rRNA studies revealed a one nucleotide difference (99.8%) between the Lernaea cyprinacea species of this parasite and L. cyprinacea (KY435939) from the Genbank database. | ||||
