Sažetak
Common carp production has an important status in Croatian aquaculture. Also, sport fishing of common carp in open waters is very popular, but is often based on stocking from fish farms. 243 individuals from 5 hatchery and 5 feral stocks were analysed using fifteen microsatellites. A total number of 148 alleles were recorded. However, the mean number of alleles per locus was remarkably low. Pairwise FST values (0.026-0.130) were significant (P<0.01), demonstrating differentiation among populations. AMOVA results for 10 populations indicate that the percentage of variation among populations was 6.26%, which is lower than the variation within populations (91.04%). Our results have demonstrated that microsatellite markers are a powerful tool in monitoring the genetic condition of different stocks. A higher genetic variability of feral carp populations in comparison to hatchery stocks has been found. This is particularly important in the light of the global threat to feral carp stocks. Five hatchery stocks of common carp have important status in aquaculture, so our results on genetic variability within/among them and the relationship among them can provide a new background of knowledge in stock conservation and breeding programs in Croatia.
