    Due to natural dispersal and artificial transplantation, it is currently distributed
    in most parts of Europe, Central Asia, North Africa and Xinjiang Irtysh River system, Ili River system and Heilongjiang River system.
    Due to its fast growth, adaptability and high nutritional value, pikeperch has become an important freshwater breeding object
    in Europe and Central Asia.
     
    The biotechnology team of Heilongjiang Institute of Chinese Academy of Fishery Sciences successively collected six population samples of pikeperch from Ulungu Lake (UL) in Xinjiang, Tengger Lake in Ningxia (TL), Heihe section of Heilongjiang River (HR), Fuyuan section of Ussuri River (WR), Xingkai Lake (KL) and Dandong section of Yalu River (YR) to carry out population genetics research
    .
    Based on the pikeperch genome sequence, 30 microsatellite sequences were developed and screened, and the genetic structure and genetic
    differentiation of 6 populations were evaluated.
    The results showed that the UL, TL, HR, YR pikeperch populations were at high polymorphism levels (PIC≥0.
    5), while the WR and KL populations were at moderate polymorphic levels (0.
    25≤PIC<0.
    5).

    There was moderate genetic differentiation among pikeperch populations (FST=0.
    2093>0.
    15), while the four pikeperch populations of UL, TL, HR and YRs had high genetic differentiation with KL and WR populations
    .
     
    Based on the above results, it is believed that the Chinese pikeperch population is divided into two genetic lineages, and the UL, TL, HR, YR PIKEPERCH POPULATION BELONGS TO ONE GENETIC LINEAGE, AND IT IS SPECULATED THAT IT MAY SPREAD FROM CENTRAL ASIA TO CHINA THROUGH THE ELTYSH RIVER.
    The KL and WR pikeperch populations belong to another genetic lineage and are speculated to have spread to China
    via Xingkai Lake.
    The relevant research results were published in the JCR Region 1 journal Aquaculture Reports, paper link: https://doi.

    The research was supported
    by the Special Project for Fishery Resources and Environment Survey in Key Waters in Northwest China, the Special Project for Fishery Resources and Environment Survey in Key Waters in Northeast China, and the National Freshwater Aquatic Germplasm Resource Bank Project.
