The spatial distribution of fish individuals is affected by habitat conditions and species ecological characteristics, and it also reflects the longtime adaptation to habitat at the phenotypic and genotypic level. Adaptation to a typical habitat over a long period of time causes fish species to form a distinct geographic population. As a typical river-lake migratory fish, the silver carp habitat selection was determined by its migration preference and genetic features. In this study, 15 microsatellite fluorescent markers combined with capillary electrophoresis were used to analyze the genetic diversity, genetic differentiation, and structure of wild silver carp populations in the Sanzhou (SZ), Hukou (HK), Anqing (AQ), Zhenjiang (ZJ), and Rugao (RG) sections of the Yangtze River. The results showed that 15 simple sequence repeat (SSR) loci exhibited medium to high polymorphisms (polymorphic information content (PIC) range 0.466-0.918. The overall genetic diversity in the Yangtze River w ....
