Abstract

Age and growth of Labeo dussumieri (Val.) of the river Pampa was determined by resorting to scale studies. Examination of margin of scales collected during different months of the year revealed that the annulus formation occurs during March-August, the peak being in May-June. Growth parameters were estimated following integrated method of Pauly and ELEFAN I and the theoretical lengths at various ages calculated by growth equation showed almost agreement with length at ages calculated by scale studies and length frequency analysis. Therefore, it is inferred that von Bertalanffy's growth equation adequately described the actual growth of L. dussumieri. The theoretical growth equation derived for L. dussumieri is: male : 473 (1_e-o.65i8(t+o.iio9))) a n d female : 496 {i-^smmMwy T he females attain asymptotic length faster than males. In natural waters the rate of growth of L. dussumieri during its first year is almost comparable with that of L. calbasu, L. rohita and L. fimbriatus
