Abstract

The age determination of a carp, Labeo calbasu (Hamilton-1822) from Vadavar river Lower Anicut, Tamil Nadu has been assessed from the 110 specimens collected between April 2010 and March 2011. Using length-frequency method and scale study, it was found that Labeo calbasu attains model length of 250, 283, 385 and 442 mm at the end of zero, 1st, 2nd and 3rd years of life respectively. The relationship between the total length (TL) of the fish and scale radius (S) was found to be linear. The age estimates from scale resulted into five age groups 0 to 4 at the model length of 150, 283, 335, 395 and 442 mm. The age estimates compared the scale and length frequency methods.
