Abstract
When analyzing a population’s genetic makeup, looking at variation of individuals and populations is a crucial factor. The management of yellow perch will be aided by this information particularly in regard to stocking or relocation. Microsatellite loci were used to analyze the genetic population structure of yellow perch Perca flavescens within and among 29 sampling areas throughout Minnesota’s basins. Seven microsatellite DNA loci were evaluated, with heterozygosities ranging from 0.41 to 0.78. The Lower Mississippi basin samples showed higher numbers of alleles per locus and greater expected heterozygosities compared to other basins, with Lake Pepin (PEP) exhibiting the highest average expected heterozygosity at 0.78. Pfeiffer Lake (PFE) also contained unique alleles. Genetic population structure analysis revealed diverse ancestral compositions among populations, with some, like BRS, TNB, and PEP, showing dominant ancestral clusters, while most others had weaker differentiation. Neighbor-joining tree analysis indicated little genetic separation within Rainy River basin populations but significant differences between Rainy River and Minnesota River basin populations. PCoA and FST values suggested four distinct genetic groups: a central/southern Minnesota & Upper/Lower Mississippi basin cluster, a highly divergent Red River basin group, and tightly clustered Rainy River and Great Lakes basin groups. This study provides valuable insights into the genetic structure, diversity, and connectivity of yellow perch populations in Minnesota. The observed variations highlight the importance of considering regional differences in genetic makeup for effective fisheries management. Understanding these genetic distinctions will inform future conservation strategies, stocking decisions, and translocation efforts to preserve locally adapted gene pools and enhance the long-term resilience of yellow perch populations in the face of environmental changes.
