Length-weight relationship and condition factor of Catla catla in reservoir Udaisagar (Udaipur, Rajasthan)


Author(s): Laxmi Kauwar Rathore and BK Sharma

Abstract: The commercially important fish species of Udaisagar reservoir Catla catla was selected for their biological study. Present study which include the length-weight relationship and condition factor of Catla catla. The exponent values of total length and weight varied from 0.138 to 0.280. On the basis of exponent value of length-weight relation, it could be concluded that Catla catla attains more weight per unit of length in the Udaisagar reservoir. The values of condition factor (K) of Catla catla was also computed and found that the species performed well. The maximum of ‘K’ value was found 1.917 in Catla catla (group A). Observed condition factor of Catla catla reported that the fish were in well condition during the study period. On the basis of length-weight data, the regression equations of body weight on total body length were calculated. The higher values of ‘n’ could be attributed to high rate of weight increase with per unit increase in length. The correlation co-efficient ‘r’ between total length and weight were found to be significant for all the length groups of Catla catla.
