| 摘 要： | 1 Introduction The redlip mullet, (Chelon haematocheilus) (Tem-minck et Schlegel, 1845), belongs to the family Mugili-dae. It is mainly distributed in the coastal areas of Korea, Japan and China (Wang et al., 2000). Because of the good adaptation to envir…

| Abstract: | Horizontal starch gel electrophoresis was used to investigate genetic structures of four populations (Dandong, Rizhao, Ningbo and Guangzhou) of redlip mullet (Chelon haematocheilus). Fourteen loci of ten enzymes (G3PDH, IDHP, LAP, LDH, MDH, MPI, PGDH, PGM, SDH, and SOD) were identified. The proportions of polymorphic loci varied from 0.07 to 0.14. The average observed and expected heterozygosities ranged from 0.02 to 0.05 and from 0.02 to 0.04 respectively among the 4 populations. The average number of efficient alleles of each locus varied from 1.02 to 1.06. The genetic distance among populations was from 0.0004 to 0.0021. The genetic distances between Dandong, Rizhao and Ningbo populations were small, while those between Guangzhou population and other three populations were relatively high. The result indicated the possible divergence of redlip mullet between the South China Sea and the other sea areas of China due to geographic isolation. |
