Description
Summary:With regard to the problem of restoring the muksun ( Coregonus muksun ) population in Western Siberia by means of artificial regeneration, the genetic differentiation of natural populations and broodstocks of fish rearing farms “Forvat” and “Sobsky” was studied. Eighty-four sequences of mtDNA (3,006 bp) containing the highly polymorphic genes ND1 and ND2 were analysed. The differences between the populations of Western and Eastern Siberia were revealed. These findings must be taken into account when attempting to restore the species population in each particular region. The genetic closeness of the muksun from fish rearing farms “Forvat” and “Sobsky” with muksun from the Ob-Taz basin gives grounds for using these broodstocks for seeding the Ob and Taz rivers.
