Study on the Parasitic infestation on the following fish species in Ahvaz

This study was carried out to determine the health status of four following Aquarium fish species in Ahvaz \Carassius auratus, Astronatus ocellatus, Hypostomas plecostomus, Poecilia reticulata .For this purpose during 1 year, 120 fish (each species 30 specimens) were transferred to the laboratory and examined. Each fish was inspected and examined by routine methods. The parasitical infection was studied by sampling from the organs. The infestation rate in Gold fish was 100% and all 30 fish were infected by at least one type of parasites. In this species the infestation rate from trematoda, protozoa and crustacean parasites were 80%, 66% and 6% respectively. In Astronatus ocellatus the infestation rate was 90% (90% trematoda and 72% protozoa). In Poecilia reticulata the infestation rate was 50% (23% trematoda and 13% protozoa and 13% crustacae). In Hypostomus plecostomus the infestation rate was 60% (60% trematoda and 13% protozoa). In this study following protozoa were detected: Ichthyophethirius sp., Cryptobia sp., Trichodina sp., Myxobolus sp., Lerneae, Hexamita and Dactylogyrus sp.
