Abstract: The study is an attempt to estimate the age and growth and Virtual Population Analysis (VPA) of Harpodon nehereous by the FiSAT programme from length-frequency data collected from Kutubdia channel of the Bay of Bengal. Growth parameters L∝ and K were found to be 24.48 cm and 1.50/yr respectively. This fish attained 19.17cm at the end of 1(one) year. The equation for length-weight relationship of H. nehereus was W= 0.00243TL3.051. The relationship was significant at 5% level (r = 0.997). The asymptotic weight was 43.69g. The relation condition factor ( kn ) values ranged from 0.908 to 1.22 (x̄ = 1.003, SD ± 0.081). Relative condition values changed during various months: highest peaks denoting the spawning period and the trough and small peak representing the cyclic gonadal development. Sexual maturity was attained when the fish attained 13 cm length.
