The aim of this study was to determine the prevalence of this parasite in Mazandaran. The effects of habitat temperature and kind of pool (sandy-cement) were considered as well. Methods: In this study, 103 fish samples were obtained in all stages; the samples (male and female) were divided into 3 groups based on length of fish, temperature, origin of cultured fish, kind of pool, height from sea and sex.
