Comparative growth rates of C. catla, L. rohita and C. mrigala of the Govindgarh lake are studied by means of scales. The relationship between fish length and scale length and time of formation of annuli are estimated. Instantaneous and absolute growth rates of fishes have been calculated separately for each age group. August to October and February to April have been observed as the periods of highest growth and winter months as the period of least growth. The growth curve of first year class fishes was affected chiefly by intensity of feeding and of adults by feeding and maturation of gonads.
