| Popis: | Parasites of fishes were investigated through the caught fishes in Zanjan province in Iran during September 2002 to August 2003. We used cast nets to sample a total of 155 specimens in five stations including Sohrein, Hasan Abdal, Khandagthloo, Sojasrood and Ghezel Uzoon in Zanjan provice. The specimens were identified as Alburnoides bipunctatus, Alburnus filippi, Barbus lacerta, Capoeta capoeta gracilis, Carassius auratus, Ctenopharyngodon idella and Leuciscus cephalus. Then, they were transferred alive to the laboratory and kept in five groups of aquariums at the stations. We measured weight and length of specimens, transected their spinal cord and we investigated their infections with parasites by microscope and stereomicroscope. Totally, 72 specimens were infected with four protozoan parasites as Ichthyobodo necatrix, Ichthyophthirius multifiliis, Chilodonella pisicola, Tricodina perforata and 58 specimens were infected with two myxosporean and six metazoan parasites Myxobolus cristatus, M. musajevi, Capillaria sp., Neoechinorhynchus rutili, Lernaea cyprinacea, Ergasilus peregrinus, Lamproglena compacta and Tracheliastes longicollis. This is the first report of fish parasitology study in Zanjan province. |
