The Mean

There are two stocks of American paddlefish Polyodon spathula in Poland, one in Pogorze and the other in Wasosze. These stocks were established from small quantities of eggs imported from the USA in 1995. In this study, we examined genetic variation at seven microsatellite loci in adult fish from the two Polish farms and one stock farmed in Gorny Tykich in Ukraine. Our data were compared with those reported for one native population from the Mississippi River (USA). The polymorphism of examined loci varied in the Polish and Ukrainian stocks, showing 25&minus;30 alleles across each stock (3.6&ndash;4.3 alleles per locus), though they were less polymorphic than those in the Mississippi (49 across the population, 7.0 per locus). The mean observed heterozygosity per locus estimated in Polish stocks (0.59&minus;0.60) was comparable to that found in the Mississippi (0.68). The Garza-Williamson index and values of the heterozygosity excesses revealed a reduction of genetic variation in all the three European stocks (probably resulting from bottleneck or founder effect). Finally, genetic distance measurements confirmed a closer relationship between Pogorze and Wasosze <br />(F<sub>ST </sub>= 0.007) stocks than between these two Polish stocks and that from Ukraine (F<sub>ST</sub> = 0.096 and F<sub>ST </sub>= 0.054). &nbsp;

Genetic variation in four reared stocks of European sea bass Dicentrarchus labrax L., originating from Greek commercial farms, was assessed using five polymorphic microsatellite markers and was compared with that of three natural populations from Greece and France. The total number of alleles per marker ranged from 8 to 22 alleles, and hatchery samples showed the same levels of observed heterozygosity with samples from the wild but substantially smaller allelic richness and expected heterozygosity. The genetic differentiation of cultivated samples between them as well as from the wild origin fish was significant as indicated by Fst analysis. All population pairwise comparisons were statistically significant, except for the pair of the two natural Greek populations. Results of microsatellite DNA analysis herein showed a 37 % reduction of the mean allele number in the hatchery samples compared to the wild ones, suggesting random genetic drift and inbreeding events operating in the hatcheries. Knowledge of the genetic variation in D. labrax cultured populations compared with that in the wild ones is essential for setting up appropriate guidelines for proper monitoring and management of the stocks either under traditional practices or for the implementation of selective breeding programmes.
