Samples were collected from Tajan River, Anzali Lagoon and some fish farms. Immediately after caught live fish were transported to laboratory and kept in aquarium for further examination.

Morphology of spores, development stages of plasmodia, tissue specifications and cyst production of these parasite species were investigated in the present study. Four of the Myxosporeans were identified as potential pathological hazards for three fish species. These are Myxobolus pavlovski for Silver Carp (Hypophthalmichthys molitrix) and Big Head (Hypophthalmichthys nobilis), M. bramae for Kutum (Rutilus frisii kutum). M.muelleri and M. ellipsoides f.....
