Abstract: A research into length-weight relationship and condition factor (K) of Catla catla was carried out in Lake Pichhola, Udaipur district during the period from November (2015) to March (2016). The Catla catla attained more weight per unit of length in early age (1-2 years) in the lake Pichhola thus, showing a linear growth. The correlation coefficient was positive and highly significant (r = 0.886** to 0.580**) in length groups B (61-70 cm) and D (81-90 cm). The values of condition factor ‘K’ varied between 1.307 to 2.145. The nearness of the K values to 1.0, in length group B, C and D indicates the environment suitability of the lake Pichhola for good growth of fish. Further, the high value of condition factor (K) in group A (2.145) indicate higher increase in weight in relation to length. Variations in length-weight relationship between different size-groups could be attributed to the prevailing environmental conditions, available food and space besides, the biological features specific to the species.
