Abstract: In the present studies, Length-weight relationship of Labeo dero (Family: Cyprinidae) was studied on about 300 specimens (ranging from 3.1cm to 27.5 cm Total length and 0.43gm to 200.10 gm of Body Weight). The value of correlation coefficient indicated a highly significant correlation between length and weight in all the age groups. It was 0.978 in age group 0+, 0.999 in age group 1+, 0.995 in age group 2+, 0.983 in age group 3+ and 0.995 in pooled data of all age groups. The parabolic equation obtained were W= 0.11480L2.756, W= 0.00575L3.149, W= 0.00395L3.319 and W=0.04920L2.521 in 0+, 1+, 2+, 3+ age groups respectively. The condition factor (K) also varied in different age groups was found to be decreasing with advancing age viz. 1.2268, 1.1015, 1.1008, 1.0343 in 0+, 1+, 2+ and 3+ age groups respectively.
