This study was designed to investigate the rate of common carp (Cyprinus Carpio) to Lernaea cyprinacea. 275 pieces weighing more than 150 grams were caught from 4 fish farms in the Shushtar city located in the four cardinal directions, in September and October of 1388. The collected samples were placed in 20 liter drums containing 10% formalin and then were transferred to the laboratory of Veterinary School in University of Kazerun. The Samples were studied in terms of total length, standard length, body height and weight. In the next stage, the infected fish were separate from other fish and infected were evaluated regarding Lernaea Cyprinacea infection. : The results showed that 69 % of the total numbers of fish caught were diagnosed with Lernaea Cyprinacea. Frequency of fish’s infection to the parasites was reported as 09/25%. Also, investigation of the relationship between total length and weight with infection rate to Lernaea Cyprinacea showed a significant relationship between the variables (parameters) above with the rate of infection to the parasite.This study determined the prevalence of carp fish infection to Lernaea Cyprinacea as 09/25%. This study also indicated that a significant relationship between the total length, standard length and weight with the rate of infection. https://biomedpharmajournal.org/vol7no1/infection-rate-of-common-carp-cyprinus-carpio-to-lernaea-cyprinacea-parasite-in-warm-season-of-year-in-farming-ponds-of-shushtar-region-in-khuzestan-province/ Cyprinus Carpio Lernaea Cyprinacea parasite farming pond Khuzestan
