According to the results of helminthological studies, 32 species of helminthes were identified in 13 species of fish in the Bukhara region of Uzbekistan, including 12 species of cestodes, 6 species of trematodes, 12 species of nematodes and 2 species of acanthocephalans.

The nematode of Philometra kotlani, first recorded in the fish of Uzbekistan. Infection of the studied 13 fish species averaged: cestodes: prevalence is 16.8%, intensive infection is 1-63 specimens; trematodes: prevalence - 2.1%, intensive infection - 1-6 specimens; nematodes: prevalence - 14.8%, intensive infection - 1-14 specimens and acanthocephalans: prevalence - 1.2%, intensive infection - 1-4 specimens. The total percentage of infection of fish with helminthes is 8.7%. The number of parasites per fish ranges from 1 to 63 specimens.
