Length-weight relationship and condition factor of rohu-catla hybrid in Lake Udaisagar, Udaipur, Rajasthan
Author(s): Gokhale GS, Sharma SK, Sharma BK, Upadhyay B
Abstract: Rohu-catla hybrid contributes significantly (14.42%) in the total fish landing og lake Udaisagar. The fish attained more weight per unit of length in early age (1-2 years) in the lake thus, showing a linear growth. The correlation coefficient was positive and highly significant (r = 0.0.803** and 0.748**; P = < 0.01) in length groups A (24-29 cm) and C (36-41cm). The values of condition factor ‘K’ varied between 1.711 to 2.775. The nearness of the K values to 1.0, in length group C (1.711) and D (1.742) indicates the environment suitability of the lake Udaisagar for good growth of fish. Further, the high value of condition factor (K) in group a (2.775) and B (2.652) 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. The latter results into varied growth performance of the fish under study during different age groups.
