ABSTRACT: The present work, based on 600 specimens (ranging from 2.9 cm to 13 cm of Total Length and 1.03 gm to 19 gm of Body Weight), describes Length–Weight relationship and Condition factor in different age groups of Aspidoparia morar (Family: Cyprinidae) from river Tawi and its tributaries. The value of correlation coefficient indicated a high degree of correlation between length and weight in all the age groups. It was 0.988 in 0+ age group, 0.956 in 1+age group, 0.960 in 2+age groups and 0.971 in 3+age group. The parabolic equations obtained were W=0.2249L1.436, W=0.01148L2.86, W=0.009997L2.941 and W=0.007228L3.073 in 0+, 1+, 2+ & 3+ age groups respectively. The condition factor (K) was found to decrease with advancing age viz. 1.057, 0.882, 0.875 and 0.877 in 0+, 1+, 2+ and 3+ age groups respectively.
