Abstract
In this study which has been done between April 2008 and June 2009, fishes captured from Ağrı and Erzurum were examined by endoparasite fauna. Examined fishes are as follows: Acanthobrama marmid Heckel, 1843, Alburnus akili Battalgil, 1942, Barbus plebejus Bonaparte, 1839, Barbus mursa Güldenstädt, 1773, Capoeta barroisi Lortet in Barrois, 1894, Capoeta capoeta Güldenstädt, 1773, Cyprinus carpio Linnaeus, 1758, Leuciscus cephalus Linnaeus, 1758. Consequently, a total of 908 individual parasites were detected from six parasite species; Rhabdochona denudata Dujardin, 1845 (Nematoda), Neoechinorhynchus sp. and Pomphorhynchus sp. (Acanthocephala), Bothriocephalus acheilognathi Yamaguti, 1934, and Caryophyllaeus laticeps Pallas, 1781 (Cestoda), Allocreadium isoporum Looss, 1894 (Digenea). The distribution of the infection prevalence, mean intensity, and abundance values of parasite species were determined. As a result of our study, 93 of 233 (39.91%) fish were reported with parasites.
Highlights
Fishes are one of the important basic nutritional elements in animal food sources and provide high-quality protein and a large variety of vitamins and minerals (Öztürk, 2005; Balami et al, 2019)
A total of 233 fish were caught as part of this study, 98 of which were from the Murat River and 135 from the Aras River
Bothriocephalus acheilognathi was found in Cyprinus carpio caught from the Aras River, Caryophyllaeus laticeps was found in Acanthobrama marmid and in C. capoeta caught from the Aras River, Pomphorhynchus sp. was found in the Leuciscus cephalus, C. capoeta and Barbus plebejus caught from the Aras River, while no Pomphorhynchus sp. was determined in fish caught from the Murat River
Summary
Fishes are one of the important basic nutritional elements in animal food sources and provide high-quality protein and a large variety of vitamins and minerals (Öztürk, 2005; Balami et al, 2019). Fishes are constantly together with parasites in the natural environment, parasitic diseases constitute one of the most important problems of fisheries (Taşçi & Topçu, 1990; Öztürk, 2005; Aydoğdu & Selver, 2006). Parasites exogenously live in the gills, skin, fins, and eyes, endogenously live in various internal organs of fish species (Dörtbudak et al, 2019). It is reported that almost 50% of the fish larvae die from parasitic infections in crowded pools (Dörücü & Mutlu, 2008). Parasites are reducing the nutritional value of the fish and prevent them from growing, reproducing, and feeding (Özan & Kır, 2005).
