Progeny would be reared and released into rivers managed by the Fishing Club Bled. In this study was performed genetic characterization of broodstock from Bled fish-farm in order to assess hybridization of native brown trout of Danubian phylogeographic lineage with trout of the allochtonous Atlantic lineage. Material and Methods: DNA was isolated from fin clips of 20 males and 20 females from broodstock. PCR-RFLP technique was used for distinguishing between Atlantic and Danubian lineages on the basis of control region of the mitochondrial DNA (CR mtDNA) and lactate dehydrogenase gene (LDH). Results: Results show a high percentage of allochthonous genetic markers especially among females and confirm hybridization between native and introduced brown trout. Conclusions: Because of low percentage of native trout markers, Bled fish-farm decided to continue with collecting and genotyping fish to establish a broodstock with higher percentage of genetic markers characteristic for native trout of Danubian lineage. |
