| Abstract: | Despite almost a hundred years of studies on the Pacific cod’s biological and ecological peculiarities, many of them and especially
population structure remain poorly understood. The variability of DNA microsatellite loci Gmo3, Gmo34, Gmo35, Pgmo32, and Gmo 19 was analyzed for the cod sampled in different areas of the North Pacific. The cod sampled nearby the Southern Kurils, differed
significantly by Gmo3 and Pgmo32 compared to the populations inhabiting the Bering Sea, the Sea of Okhotsk and the coastal waters off Canada. Further, Pacific
cod of the three latter populations demonstrated high similarity (I = 0.996) in spite of considerable geographic remoteness
of these areas from one another. |
