| Abstract: | Silver pomfret (Pampus argenteus) is one of the most commercially important marine fish species in China, and its resource has declined sharply in recent years. So far, the population diversity research is rare, and the stock structure of silver pomfret is not clear which are very crucial for rational conservation and exploitation of this important species. So, five geographic samples, totally 224 individuals, were collected near coastal areas of the Bohai Sea, Huanghai Sea and East China Sea. The morphological variation among five samples was studied by using the method of multivariate morphometics. The result of cluster analysis showed that five samples were divided into 4 groups. The normalized Euclidean distance between Lianyungang (LYG) and Zhoushan (ZS) and Huanghua (HH) samples was shorter than others, which indicates that these three samples have close relationship. However, the normalized Euclidean distance between Xiapu (XP) and Lianyungang (LYG) samples was the largest. The results of stepwise discriminate analysis and canonical variate analysis showed that five samples could be separated accurately, which indicates that there were morphological differentiation among five samples. Different life history and habitat environmental factors may contribute to the morphological variation. Based on the results from cluster analysis, stepwise discriminate analysis and canonical variate analysis, there were probably three different morphological populations in the Bohai Sea, Huanghai Sea and East China Sea, that is Huanghai Sea-Bohai Sea, northern East China Sea, and southern East China Sea populations. |
