Abstract :
Abstract[1] The Abramis brama orientalis is a commercially valuable species distributed in the Iranian shores of the Caspian Sea, particularly in the coasts of the Gilan province, Anzali Wetland and in the lake behind the Aras Dam. Changes in environmental conditions and occurrence of disease are associated with changes in some hematological parameters. The effects of parasitical infection on hematological parameters in 175 Abramis brama were studied during the fishing season for this species in 2008-2009. After fish catching and transporting to laboratory, different organs like eye, skin, gill and digest system surveyed. In this study, average length (28.67±2.86 cm) and average weight (298.18±62.74 g) were. Based on studies 4 parasite species: Diplostomum spathaceum, Trichodina sp ., Ligula intestinalis and Caryophyllaeus laticeps introduced. According to results, maximum outbreak (73%(, average frequency (1.84 pieces) related to Ligula intestinali, maximum average virulence (3.96 pieces) related to Caryophyllaeus laticeps and minimum outbreak (22%) belonged to Diplastomum spathaceum and Caryophyllaeus laticeps, minimum average virulence (2.06 pieces) belonged to Diplastomum spathaceum, minimum average frequency (0.45 pieces) Caryophyllaeus laticeps and parasite number amplitude (1-6 pieces) were related to 4 parasite species. *Corresponding authors; hayatbakhsh_mohammadreza@yahoo.com
