英文摘要 | This study analyzed and compared variations of the sulcus and otolith outlines of three geographic stocks(Huanghe(Yellow) River estuary(HHE), Jiaozhou Bay(JZB), and Changjiang(Yangtze) River estuary(CJE)) of white croaker P ennahia argentata in northern Chinese coastal waters. The sulcus and otolith outline analyses via elliptical Fourier transform(EFT, i.e., outline analysis) achieved an overall classification rate of 80.4% and 87.2%, respectively. Based on a combination of sulcus and otolith shape indices(SIs) and two derivative ratios, a moderate discriminatory efficiency of 64.7% was obtained. The results indicate that sulcus outline analysis could be used alone to discriminate white croaker stocks, and that both sulcus and otolith outline analyses discriminated the fish stocks at a higher classification rate than the shape indices. The sulcus outline analysis provided complementary information to the whole otolith outline analysis for stock discrimination. Both the sulcus and otolith outline analyses efficiently discriminated between the most geographically separated CJE and HHE stocks, indicating that they could be considered discrete stocks for fishery management. |
