Description Studies on the age and growth of three Indian major carps viz. Cotlo
catlo (Ham). Cirrhino mrigolo (Ham) Dnd Lobeo rahita (Ham) based on
scale and the length frequency data are presented. The markings on
the sca les of these fishes were used as indices of age, aftar ascertaining
the annual nature of formation of growth checks. It was found that in
these three fishes rings were laid down almost during the same period
i.e. May to August. The fesult obtained from scale study is compared
with Petersen Method. A close agreement can be seen in their va lues
obtained. Von Bertalanffy's growth equation was used for fitting the
growth data obtained by scale study and it adequate ly describe the
actual growth of those fishe s. The length at age and the rate of growth
of these fishes were compared and it was found that rate of increase
in length was faster during the initial periods of life and dec rease
when they become old .
