Abstract[1] In order to survey on the incidence of Lernea sp. on the big head carp (Aristhichthys nobilis), in rearing ponds of Shushtar, lies in Khuzestan province during warm season, 275 fish were captured from four ponds by fishing net and transferred to laboratory of veterinary medicine, Kazerun Branch of Islamic Azad university by Containers of formaldehyde 10%. After identifying the Lernea sp. by identification keys, biometric operations were performed on infected fish. The results showed that from 275 fish, 78 fish were infected by lernea sp. which formed 36.28% of the captured fish. Results showed that there was no significant relationship between total length and body weight with number of lesions on the body and also between lesions and coefficient factor (P>0.05). * Corresponding Authors; Email: [e-mail]
