In this paper, length-weight relationship and condition factor (K) for important Rohu-catla hybrid from lake Pichhola are described. Pichhola is freshwater lake, is situated in Udaipur district of Rajasthan. This study aimed to estimate the length-weight relationship and characterize the condition factor of Rohu-catla hybrid the most abundant and economically important species in lake Pichhola. The fish attained more weight per unit of length in early age (2 years) in the lake thus, showing a linear growth. The correlation coefficient was positive and highly significant (r = 0.982** and 0.793**) in length groups A (26-30 cm) and D (41-45 cm). The values of condition factor 'K' varied between 1.343-1.836. The high value of condition factor (K) in group A (1.836) and D (1.626) indicate higher increase in weight in relation to length.
