| Some biological aspects of Asp Aspiusvoraxwere studied from September 2014 till April 2015 for the Jeryan and Qutba stations in Tharthar Lake/ Salahaddin, Iraq. 66 samples were fished with standard length 17.8-53.3 cm. less the lowest udmber of fish was recorded in the second station 6.06% in December 2014 and for the first station was in march 2015, while the highest record was 18.18% in September 2014 in the second station and in April 2015 in the first station. Less standard length was in record for the fished that the second station 26.32 cm and 20.73 for the first station during sapleafar and December 2014 respectivelylawe the highest standard length observed in the second station 48.55 cm in September 2014 and for the first station was 45.20 cm in March 2015. It was clear from the a value for the straight length relationship which was Positive relationship between standard length and body depth, body width, distance before and after dorsal fin with 32.99, 0.09, 1.67, and 1.26respectively. A positive relationshipako occurred between standard length and each of head dimensions such as length, depth, width, and snout length as well of miuhdimaurionscepresentud by width and hight. A conclusion obtained from this study that there were asymmetry in the relation between body length and other dimensions represented by d.Herea morphometric parameters and there were a symmetry growth for these fish lived in different area of Tharthar Lake. | ||
