Months from February 2014 to July 2014 sampling of fish parasites within 6 months of the six research stations up and down the river Hableroad, Ali Fountain, King lights martyr Dam the Fishing nets 150 pieces of the fish. The study of microscopic lesions in the skin, gills, fins and eyes of 2 different parasite species, genera such as: 1 genus Ligula intestinalis class Cestoda, Identify the seven genera of Monogenea category includes 2 genera Gyrodactylus. sp, 1 genus Dactylogyrus. sp, 1 genus Dactylogyrus lenkorani, 2 and 1 Paradiplozoon. sp and Diplozoon megan.The highest and lowest diversity and parasite densities respectively with 3 and 1 Cyprinus carpio and Albumus charusini. The fish resources of this province were the highest and lowest classes Monogenea and Cestoda 7 sex with one gender, It was reported two sex organs Paradiplozoon. sp and Gyrodactylus. sp jointly Cyprinus carpio and Alburnoides bipunctatus. Length-weight regression analysis and Pearson's correlation coefficient 2 domain (P< 0.05) indicates the correlation is imperfect and partial direct and inverse correlation Cyprinus carpio and Alburnoides charusini and Capoeta capoeta gracilis.
