The development of aquaculture in the past decade and concern about the prevalence of parasites causing more experts attention to this parasites problem and their importance in reducing reproduction of aquatic. This research investigates Bighead Carp (Aristhichthys Nobilis) affection rates to Lernaea cyprinacea. 275 fishes weighing more than 150 grams of 4 Shushtar fish farms in four cardinal directions were caught in September and October of 2009. The caught samples were placed in 20 liters barrels containing 10% formalin and then were transported to the laboratory of Veterinary Medicine of Kazerun University. These samples were studied of total length, standard length, body height and weight. In the next stage, the contaminated fish separated and affection rates to Lernaea Cyprinacea of contaminated fish was assessed. The results showed that 78 fishes of the total caught fish were affected by Lernaea Cyprinacea. Contamination frequency of investigated fish to the mentioned parasite reported 36/28%.also the relationship between total length and weight with affection rates to Lernaea Cyprinacea studied and no significant relationship between the above variables and affection rates of mentioned parasite was observed. In the present study only the Bighead Carp affection rates to Lernaea Cyprinacea investigated and the only species on contaminated fish was Lernaea Cyprinacea. https://biomedpharmajournal.org/vol7no1/the-study-of-bighead-carp-aristhichthys-nobilis-infection-rates-to-lernaea-cyprinacea-in-the-hot-season-of-khuzestan-shoshtar-fish-farms/ Bighead Carp Lernaea Cyprinacea fish farms Khuzestan
