Abstract

The study presents for the first time the Cherna River, southern Bulgaria, Aegean water basin, the results of research on the biological diversity and helminth communities of the Round-scaled barbell Barbus cyclolepis Heckel, 1837. 30 specimens of B. cyclolepis are studied. Infection by 5 species of helminths are found (Allocreadium isoporum (Loos, 1894); Bathybothrium rectangulum (Bloch, 1782); Caryophyllaeus laticeps (Pallas, 1781); Capillaria petruschewskii Zeder, 1800; Neoechinorhynchus rutili (Müller, 1780)). The infection indices and the dominant structure of helminth communities are presented. Basic biotic indices are determined. Helminth communities are analyzed at two levels: infracommunity and component community. All established parasite species are autogenous for the helminth communities of the Round-scaled barbell from the freshwater ecosystem of the Cherna River. New data for helminths and helminth communities of B. cyclolepis are presented. The bioindicator significance of helminths and helminth communities are discussed. [ABSTRACT FROM AUTHOR]

Abstract

Ecological monitoring was performed on Chepelarska River using Barbus cyclolepis Heckel, 1837, and its parasite communities as bioindicators. Helminth parasites are recorded in 45.83% of the examined specimens of the round-scaled barbell from the freshwater ecosystem of the Chepelarska River. Two species of parasites are fixed: one acanthocephalan species Pomphorhynchus laevis (Zoega in Müller, 1776), and one nematode species (Rhabdochona hellichi (Sramek, 1901). The analysis of the dominant structure of the found parasite species is presented to the component and infracommunities level. In the component community of Barbus cyclolepis from Chepelarska River R. hellichi is core parasite species (P%=37.5), and P. laevis is an accidental parasite species (P%=7.41). The determined basic ecological characteristics, biotic indices, and bioindicator significance of the established parasite species were discussed for ecological evaluation of the state of the studied freshwater ecosystem. The established in this study parasite species are considered and compared with previous researches of parasite communities of Barbus cyclolepis in Bulgaria. This is the first report of Pomphorhynchus laevis and Rhabdochona hellichi from Chepelarska River, Bulgaria. [ABSTRACT FROM AUTHOR]
