Abstract: The present study was carried out to calculate the length-weight relationship and condition factor of Cyprinus carpio var. communis and Schizothorax niger. A total of 360 samples each of C. carpio var. communis and S. niger were collected from Dal lake from August 2018 to July 2019. Length-weight relationship of C. carpio var. communis and S. niger bothindicates negative allometric growth. The functional form of Length-weight relationship of C. carpio was fitted as Log W = -3.984+2.615 Log L (Pooled), Log W = -3.754 +2.516 Log L (Male) and Log W = -4.162+2.692 Log L (Female) while for S. nigerLength-weight relationship was established as Log W = -3.577+2.399 Log L (Pooled), Log W = -3.644 +2.424 Log L (Male) and Log W = -4.162+2.692 Log L (Female) . The value of growth coefficient (b) for pooled data was found to be greater for C. carpio (2.615) than that of S. niger (2.399) which indicates better growth in C. carpio as compared to S. niger. The value of the condition factor (K) of the common carp ranged from 1.151 to 1.928 while as in case of S. niger it ranged from 0.966 to 1.32 which indicates better growth of C. carpio.
