Studies on the age and growth and population dynamics of Otolithes cuvieri (Ttewavas) bated on the data collected for a period of six years from 1979-80 to 1984 85 off Bombay waters are reported here. This species attains 170 mm, 260 mm and 318 mm at the end of first, second and third years of its life respectively. The von Bertalanffy's growth parameters estimated were as follows: Loo = 395 mm, K = 05331 (annual), to = 0. 06246 years. Using the length-weight relationship formula Woo was calculated at 6)5 gms. Instantaneous rates of total, natural and fishing mortality were estimated as Z = 2.64, M — 1.30 and F = 1.34. Exploitation ratio (E) and the exploitation rata (U) were found to be 0.50 and 0.47 respectively.
