Abstract
A stock assessment of Shabbot, Barbus grypus community was studied in Euphrates river, south of Iraq. Monthly samples were collected from September 2002 to December 2003. A total of 749 specimens was collected ranging between 9.8 to 62.9 cm in total length and 10-6250 gm in total weight. Fishes and ranged from1-5 years age. According of Gulland and Holt by using FiSAT program, the growth factors values L and K were 75.5cm and 0.21 respectively. Fishes natural mortality rate (M=0.52) was more than fishing mortality rates (F=0.39). The exploitation rate (E) was under optimum level (0.42). The annual recruitment patterns for one year showed two unequal modes. The major one was the second peaked which contributed 52.12% and recorded the highest peak during July (19.56 %).
