  In the present study a total of 180 S.glanis (60 fish for each area) were collected from Aras, Mahabad and Zarrineh (shahid kazemi) dam reservoirs in the one-year survey of 2018. The seasonal prevalence of infection to Siluris glanis in Aras, Mahabad and Zarrineh were a چکیده کامل

  In the present study a total of 180 S.glanis (60 fish for each area) were collected from Aras, Mahabad and Zarrineh (shahid kazemi) dam reservoirs in the one-year survey of 2018. The seasonal prevalence of infection to Siluris glanis in Aras, Mahabad and Zarrineh were as spring (60%, 56%, 59%), summer (70%, 66.5%, 69%), Autumn (63.3%, 66%, 64%) and winter (45%, 39%, 41%) respectively. Maximum infection intensity (Mean ± SE) of P.osculatus was determined in Aras (6.61 ± 0.5), Mahabad (5.82 ± 0.61) and Zarrineh (5.7 ± 0.56) dams in summer. The numbers of parasites were ranged from 1 to 17 in different seasons. The prevalence and intensity (Mean ± SE) of infection were significantly different in summer and winter with the other seasons (p<0.05). Data analysis had demonstrated that infection rate in affected fish mostly depended on seasons. Also, there was no significant difference in infection to this parasite between male and female European catfish. Also, pathological study demonstrated that scolex adhesiveness to the intestine of Siluris glanis caused mechanical damages on it. According to the results, infection of freshwater catfish to Protocephalus osculatus enjoyed the highest prevalence in the study area. پرونده مقاله

  Nowadays, ornamental fish are considered to be of value in most countries due to their beauty and variety. The living, beautiful and lively environment of aquariums has made people to be interested in having an aquarium, however small in size, at their home or work. The main aim of this study is to identify the parasitic elements in ornamental fish (92 Goldfish , 32 Oscar fish, 18 Flower fish, 24 Arvana fish, and 41 Discus fish) that are culled from fish breeding centers in Urmia. Classification of the fish was carried out based on their morphological characteristics. The results of the study indicate the presence of parasitic infection of these fish in four protozoan species including Ichthyophthirius multifiliis, Trichodina spp, chilodonella spp and Hexamita spp. Also, Diplostomum spataceum, Dactylogyrus spp and Gyrodactylus spp were observed from monogenea and digenea trematodes and lernaea spp from crustose parasites. پرونده مقاله
