The helminths were fixed in 70% ethanol, stained and identified. The overall prevalence was 16%. The identified helminths were as follow: digenetic trematode (Stephanostomum sp., with a frequency of 1%), cestode (Uncibilocularis sp., 1%; Tetragonocephalum sp., 2%; Grillotia sp., 4%) , and nematode (Raphidascaris sp., 3% and Anisakis sp., 5%) . The highest infection rate was belonging to Anisakis sp. (5%). There were significant differences between prevalence and weight of the infected fish.
