    Occurrence and intensity of parasites in Prussian carp, Carassius gibelio from Anzali wetland, Southwest Caspian Sea (2018)
    Details
    Publication Date: 2021-05-19
    Description: The aim of this study was to detect the occurrence of parasites in Prussian carp, Carassius gibelio as the most important alien fish in Anzali international wetland. This undesirable fish was introduced accidentally to Iran with Chinese carp fries which imported to the country during the last decades and then acceded to Anzali wetland. Today this fish has significant stocks in Anzali wetland but there have been limited studies about the parasites of this fish in Anzali wetland. During this study a total of 90 Prussian carp were collected by electrofishing and gillnets from April through July 2012. After recording biometric characteristics, common necropsy and parasitology methods were used. A total of 2715 individuals out of 11 parasite species were recovered. Parasitofauna consisted of: two protozoans, Ichthyophthirius multifiliis and Trichodina sp. one nematode, Raphidascaris acus one trematode, Diplostomum spathaceum six monogeneans, Dactylogyrus formosus, Dactylogyrus dulkeiti, Dactylogyrus baueri, Dactylogyrus arquatus, Dactylogyrus inexpectatus and Gyrodactylus kobayashii and one crustacean, copepodid stage of Lernaea cyprinacea. The monogeneans had the highest prevalence values (88.89%). The occurrence of D. inexpectatus in C. gibelio is reported for the first time in Iran.

    Study of Parasites occurrence and intensity in fishes of Anzali Lagoon (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Tish survey prolonged from summer 2011 trough summer 2012. During this period 574 samples of different fish species were investigated for their parasites. Totally 30 species of parasites isolated of the fishes. Some of the isolated parasites are recorded for the first time in Iran. Rafidascaris acus Orientocreadium siluri, Silurotaenia siluri, Acanthocephalus lucii , Argulus foliaceus has recorded for the first time from European catfish, Silurus glanis, and Dactylogyrus inexpectatus has recorded for the first time from Gibel Carp, Carassius auratus gibelio, in Anzali wetland. Statistical comparison of parasites infections and intensity between the different area of Anzali wetland were done. Infection of Pike, Esox lucius, to Diplostomum spathaceum, Raphidascaris acus and Monogenean in western parts of wetland were significantly different from the Eastern and Central areas (p〈0.05). So based on the data have concluded the eastern and central regions of the wetland are more polluted than the western part. Comparing the results of the present study with before ones showed that the composition of parasite species has been changed over time, while the prevalence, intensity and abundance of parasites have been increased. It may be due to changing environmental conditions such as increasing discharge of effluent, eutrophication of the wetland. This results accents to necessity of reconstruction of Anzali wetland with preference of eastern and central regions.
