A dissertation was presented at the Academic Council of the Pacific branch of VNIRO

A dissertation for the degree of candidate of biological sciences was presented at a meeting of the Academic Council of the Pacific Branch of the Russian State Research Center of Fisheries and Oceanography (VNIRO) on December 10.
 
Denis Kurnosov, head of the Intraspecific Differentiation Group at the Fish Age and Growth Research Laboratory, shared with colleagues the goals, objectives, relevance of the topic, and the main points of his dissertation, "Genetic Differentiation and Spatial Population Structure of Pacific Herring (Clupea pallasii) in the Russian Far Eastern Seas."
 
This study is the first comprehensive molecular genetic analysis of the herring population structure within its Far Eastern range.
 
The practical importance of the obtained data relates to fisheries regulation: they allowed us to establish the boundaries and extent of genetic differentiation between the main spawning herring groups in the Sea of ​​Japan, the Sea of ​​Okhotsk, and the Bering Sea, and also indicated the independent origins of several lake forms.
 
Following discussion, Denis Kurnosov's dissertation was recommended for defense in the specialty 1.5.7. Genetics.
