Genomic inbreeding and population structure of northern pike (Esox lucius) in Xinjiang, China

Northern pike (Esox lucius) is originally only distributed in the Irtysh River, and now spread into many habitats in Xinjiang, China. A total of four populations were collected from north to south in Xinjiang, including Irtysh River (RIR), Ulungu Lake (LUL), a small lake nearby Ulungu River (LJD) and Bosten Lake (LBO). We estimated population genomic parameters, performed gene flow analysis, and estimated the effective population size of each population.
