We are grateful to Captains Y. Kimura, S. Murakami, H. Irihama, and T. Tsubouchi of the Yamada Suisan Company Ltd. and their crews onboard No. 21, 1, and 2 Yamada Maru, and to the officers and crew of the RV Kaiho Maru of Okinawa Prefecture, for allowing us to board their vessels and collect specimens. We also thank U. Yamada, formerly of Seikai National Fisheries Research Institute, for both invaluable information on lizardfishes (Saurida spp.) and comments on our study, B.N. Campbell for critically reading this manuscript, and two anonymous reviewers for their constructive suggestions and comments. This study is supported in part by Research Fellowships of the Japan Society for the Promotion of Science for Young Scientists.

N2 - The age and growth of the lizardfish Saurida sp. 1 (Japanese name: Kuroeso), collected in the East China Sea from April 1998 to March 2000, were examined using polished thin sections of otolith. Length-frequency distributions clearly showed differences in the range of sizes between the sexes. All specimens larger than 400 mm in fork length were females. Monthly changes in the frequency of appearance of a translucent band on the outer margin of the otolith, and in the marginal increments, indicate that ring marks form once a year, from December to March. Male specimens had 1-9 ring marks, while females had 1-11 ring marks. Using the back-calculated fork lengths, the growth of male lizardfish was expressed as FLt = 421.7(1 - exp{-0.162(t + 1.238)})(1 ≤ t ≤ 8) and that of females as FLt = 489.4(1 - exp{-0.160(t + 0.948)}) (1 ≤ t ≤ 10). Our results suggest that females grow faster and live longer than males. A discussion of the summary of scale to age determination in lizardfish is carried out.
