Age and growth of the ribbonfish Trichiurus lepturus Linnaeus is studied by length-frequency analysis of 20,562 fish measured during October 1965 to December 1970. The fish attains an averags length of 41.6, 69.0 and 88.5 cm in l&t, 2nd and 3rd years, respectively. The growth rate is fairly faster than what hitherto believed was to be. The von Bertalanfly growth equation is fitted, which has the parameters L o3 = 145.4 cm, K = 0.29 and t ^ = -0.20 years. The length-at-age data obtained in this study compare favourably well with similar data on the same species from the northern Gulf of Mexico, East China Sea and Yellow Sea-Pohai Bay.
