VARIABILITY OF MICROSATELLITE LOCI IN POPULATIONS OF PACIFIC COD (GADUS MACROCEPHALUS TILESIUS) (GADIDAE)

Despite the almost secular period of Pacific cod investigation, the monitoring of condition of its stocks, many biological features and especially population structure remain poorly understood. The variability of DNA microsattelite loci Gmo3, Gmo34, Gmo35, and Pgmo32 in Pacific cod samples from diff...

Description
Summary:Despite the almost secular period of Pacific cod investigation, the monitoring of condition of its stocks, many biological features and especially population structure remain poorly understood. The variability of DNA microsattelite loci Gmo3, Gmo34, Gmo35, and Pgmo32 in Pacific cod samples from different areas of the North Pacific was analyzed. The data obtained show that Pacific cod from the southern Kuril Islands significantly differs (the highest differentiation was inherent in microsattelite loci Gmo3 and Pgmo32) from populations of the Bering Sea, Sea of Okhotsk and coastal waters of Canada. By this, Pacific cod of the three latter populations demonstrates high degree of similarity (I = 0,981—0,993) in spite of considerable geographic remoteness of these areas one from another. Проведен анализ изменчивости микросателлитных локусов ДНК Gmo3, Gmo34, Gmo35, Pgmo32, Gmol9 в выборках тихоокеанской трески из различных районов северной части Тихого океана. Полученные данные показывают, что треска южно-курильского региона на достоверном уровне отличается (наиболее высокую дифференцирующую нагрузку несут микросателлитные локусы Gmo3 и Pgmo32) от выборок трески и Берингова, и Охотского морей, и прибрежья Канады, демонстрирующих при этом высокую степень сходства между собой (I = 0,996), несмотря на значительную дистантную разобщенность.
