Abstract: In the present study age, growth and virtual population analysis (VPA) has been estimated by the FiSAT program from length-frequency data collected from the Kutubdia channel of the Bay of Bengal. Growth parameters L ∞ and K were found to be 16.80 cm and 1.30/year, respectively. This fish attained 12.06 cm at the end of one year. The estimated length-weight relation for the combined sex was found to be W=0.00383TL2.801. The asymptotic weight (W ∞ ) was 10.36 g. The highest peak of fishing mortality (F) occurs in the length range between 12 and 14 cm.
