The purpose of this study was to determine the concentrations of metals, cadmium, chromium, lead and nickel in Liza vaigiensis and Johnius carutta, in order to: compare metal concentrations between two species with different gender, and to determine the significance between metal concentrations in the gill, liver and muscle. The highest mean concentrations of cadmium, chromium, lead and nickel in different tissues of these two fish species were found in the liver of L. vaigiensis at 0.68, 0.83, 0.37 and 1.42 μg g(-1), respectively; while the lowest mean concentrations of cadmium, chromium, lead and nickel were observed in the muscle of J. carutta at 0.16, 0.16, 0.03 and 0.29 μg g(-1), respectively. The results showed that the metal concentrations in both species were higher in the females than in the males (except chromium in gill and cadmium in muscle of J. carutta). Also, the results indicated that the metal concentrations were different among fish tissues (one-way ANOVA, p < 0.001), but there was no difference (except lead in gills of J. carutta) between sex (male vs. female).
本研究旨在测定瓦氏黄颡鱼和红鳍笛鲷肌肉、鳃和肝脏组织中金属（镉、铬、铅和镍）的浓度，以：比较两种不同性别鱼类金属浓度的差异；确定鳃、肝和肌肉组织中金属浓度的差异。这两种鱼不同组织中镉、铬、铅和镍的最高平均浓度分别为：瓦氏黄颡鱼肝脏中的镉 0.68μg/g、铬 0.83μg/g、铅 0.37μg/g 和镍 1.42μg/g；红鳍笛鲷肌肉中的镉 0.16μg/g、铬 0.16μg/g、铅 0.03μg/g 和镍 0.29μg/g。结果表明，除了红鳍笛鲷鳃中的铬和肌肉中的镉之外，两种鱼的雌性金属浓度均高于雄性。此外，结果还表明金属浓度在鱼类组织之间存在差异（单因素方差分析，p<0.001），但在性别之间无差异（除了红鳍笛鲷鳃中的铅）。
