Study on the parasitic Infections of Aquarium Fishes

Objective: To determine parasitic infections of aquarium fishes around Esfahan Method & Materials: 1010 fish were sampled randomly. Parastitic infections of different organs, including skin, gills, eyes, blood, alimentary canal, liver, kidney, abdominal cavity, muscle and swimming bladder in six different species, including Barbus tetrazona (n=120), Betta splendens (n=170), Carassius autratus (n=102), Cichlasoma severum (n=267), Gymnocorymbus ternetzi (n=201) and Poecilia reticulate (n=150) were stdied. Blood samples were stained with Geimsa and examined. Other organs such as skin, gills, alimentary canal and other organs were examined, as well. Results & Conclusion: The incidence of different parasitic infections in fishes, for protozoans, arthropods and helminthes were 25.3%, 2.9% and 6.65%, respectively. Dactylogyrus vastator, Chiloldonella sp., Hexamita sp., Ictyoboda necator, Ichthyophtirius multifiliis, Microsporidium, Myxosporida sp., Tricodina sp. and Lernaea cyprinicea were collected from 5 (38%) species. Furthermore, Gymnocorymbus ternetzi was the least infected fish, being infected with Argulus foliaceus. Our findings revealed that the protozoal infected are very common among aquarium fishes. Although, no gross pathology was observed among infected fishes, but it is likely that in case of any changes in the environment, then parasites, become pathogen.
