Case study of microsatellite polymorphism of European perch in selected commercially important lakes of Latvia
- 4 Downloads
Polymorphism of selected microsatellite markers was described for European perch populations of inland Lake Kala and costal Lake Babites in Latvia. The data consisted of ten microsatellite loci analysed for 90 individuals from the Lake Babites (n = 45) and the Lake Kala (n = 45). Both lakes differ in water area, connection with the Gulf of Riga (Baltic Sea), lake type, and fish species. In the Lake Kala population, the average number of alleles per locus varied from 4 to 15 and in the population of Lake Babites from 4 to 12. Low but significant genetic differentiation was detected between populations (FST = 0.046). Observed and expected heterozygosity in both lakes was similar (Kala: Ho = 0.680 and He = 0.816; Babites: Ho = 0.693 and He = 0.815). The number of unique alleles per locus was 2.3 in Lake Kala and 0.6 in Lake Babites. The present study showed relatively high polymorphism of analysed microsatellite markers.
