碩士 / 國立臺灣海洋大學 / 海洋事務與資源管理研究所 / 104 / The possible stock structure of Japanese butterfish (Psenopsis anomala) in surrounding waters of Taiwan were examined based on both otolith morphometry (including morphometric indices and elliptical Fourier analysis) and otolith microchemistry (including Sr/Ca, Ba/Ca and Zn/Ca ratios) in company with previous studies. Samples of P. anomala were collected from north eastern and south western waters of Taiwan (NET and SWT, thereafter) in spring 2015, and with additional site in the South East China (SEC) in winter 2015. There were no differences found between seasons in both elemental ratios and combined morphometric analysis for P. anomala collected from NET, but differences (MANOVA, p < 0.05) were found only in morphometric analyses for sample collected from SWT. For the same season of spring, differences (MANOVA, p < 0.05) in both elemental ratios and combined morphometric analysis were found between NET and SWT, but no differences were found between NET and SWT in winter for both analyses. However, significant differences were found between SEC and NET, and between SEC and SWT in winter, indicating that different stocks may exist between surrounding waters of Taiwan and the SEC, but seasonal mixing may occur between stocks and deserve further studies. The result presented in this study may provide important guidelines for further management of P. anomala in Taiwan.
