Název v původním jazyce

Comparison of microsatellite variability in wild and cultured tench (Tinca tinca)

Popis výsledku v původním jazyce

The tench is a cyprinid fish species of increasing interest for European pond aquaculture. However, only little is known on the population genetic structure of this species; the few studies conducted so far were based on allozyme polymorphisms. In the present study, tench specific microsatellites were used for a genetic comparison of two wild populations and four cultured strains from Germany and Czech Republic. Seven out of nine loci analysed were polymorphic with a total number of alleles ranging from2 (locus MTT-2) to 19 (locus MTT-9). Wild populations showed a higher allelic richness than the cultured strains (3.73 vs. 2.43) but this difference was still not significant (P=0.062). Observed heterozygosity (0.370 vs. 0.366) and gene diversity (0.403vs. 0.343) were globally similar in wild and cultured tench. In contrast to the variability within populations, genetic differentiation was significant between all of them as estimated by FST values from pairwise comparisons. The differe
