Abstract

Some ecological and biological aspects of shabbot Arabibarbus grypus collected from Lesser Zab River at Kurdistan Region, Iraq were studied at Taq taq a district. In the period of August 2024 to July 2025. The lowest values water temperature reached for was 9.3°C during January and the highest was 29.2°C during July 2025. Water pH values were ranging between 7.4 and 8.3. Salinity concentration values were ranged between 0.21 g/l during January and 0.44 g/l during July 2025. The lower value of water transparency was 21cm recorded during February and the highest was 50 cm reached during July 2025. The highest dissolved oxygen in water was 12 mg/l at January 2025, whereas, the lowest was 7.6 mg/l during August 2024. A total of 342 specimens of shaboot Arabibarbus grypus were collected ranging between 14 and 58.8 cm in total length and between 17 and 1850 g in total weight. Length weight relationship showed that fish growth was allometric. Fish condition factor for male was ranging between 0.63 during October 2024 and 0.98 during March 2025, while for female was ranging between 0.68 during October 2024 and 1.00 during June 2025.
