A restocking programme by captive breeding was initiated in 1999 to support S. trutta abanticus population. Reared 2-year-old juveniles from randomly caught wild parental individuals in Macka breeding farm were introduced into Lake Abant. We aimed to compare genetic and morphological divergences between wild-and captive-bred populations using seven microsatellite loci and geometric morphometric measurements. A significant genetic and morphological divergences were detected between all population in F-st and canonical variate analysis based on geometric morphometric with 10 homolog landmark. Eighty-six microsatellites alleles were recorded across loci. Number of private alleles, observed alleles and observed heterozygosity are statistically significant higher in Macka captive-bred population than Lake Abant and Seven Lakes populations. Of 42 tests, three departures from Hardy-Weinberg equilibrium were detected in all populations after Bonferroni correction. Two pairs of loci (Ssa85 - Str73 and Str73-Str543) in Macka, one pairs of loci (Ssa85-Str73) in Abant and two pairs of loci (Ssa85-Str60 and Str73-Str543) in Seven Lakes populations show linkage disequilibrium. Population structure analysed with Structure software showed three genetic groups (Delta K = 3) in our studied populations. Relatedness estimates show higher mean relatedness values (r = 0.220 +/- 0.230) for Macka captive-breed population than wild populations of Abant Lake and Seven Lakes (r = 0.140 +/- 0.210 and r = 0.170 +/- 0.200 respectively).eninfo:eu-repo/semantics/closedAccessCaptive-BredGenetic and Morphological DivergencesGeometric MorphometricsMicrosatelliteSalmo Trutta AbanticusArticle10.1111/are.133844811562456302-s2.0-85019577605Q2WOS:000412517900020Q3
