This study was conducted at depth 5-20 meters from the coastal area of Bushehr during July to September, 2013. The aim of this study was identification of Bopyrid: Isopod in two shrimp species Penaeus semisulcatus and Metapenaes affinis and the effects of biological and environmental factors on its disturbance. In this study 814 kg of samples included of 735 kg of Green tiger shrimp (P. semisulcatus), 68 kg of jinga shrimp (M. affinis) and 20 kg other species were collected. The identified Bopyridae parasite was belonged to Epipenaeon ingens. The result showed that the abundance of bopyridae parasite in the Green tiger shrimp (P. semisulcatus) was 26%, which observed in the depth of 10 – 20 meters. No Bopyridae parasite was detected from jinga shrimp (M. affinis). The average weight and length of infected green tiger prwan specimens were 39.87±0.27 gr and 19.61±0.07 cm, respectively. The physiological state of infected shrimps indicated that, reduction of ovarian development and petasma in female and male, respectively. There was a significant relationship between water temperature and salinity increased with increasing of E. ingens abundance in P. semisulcatus in the studied area.Journal
