“…Taniguchi and Pérez-Enríquez, 2000). A decline of neutral genetic variation is irreversible in closed breeding programs and is indicative of random erosion at genomic scale, what can jeopardize genetic improvement since the first generation in hatchery (Vuorinen, 1984). We provide inbreeding figures obtained in silico, which are useful to figure out alternate breeding protocols within and between stocks, aiming to minimize the rate of intergenerational inbreeding.…”

The Eurasian range of the tench distribution is subdivided into deeply divergent Western and Eastern phylogroups evidenced by nuclear and mitochondrial DNA sequence markers. A broad zone of overlap exists in central and western Europe, suggesting post-glacial contact with limited hybridisation. We conducted a population genetic test of this indication that the two phylogroups may represent distinct species. We analysed variation at introns of nuclear genes, microsatellites, allozymes and mitochondrial DNA in populations from two postglacial lakes within the contact zone in Germany. The test is based on the expectation that in the presence of strong barriers to reproduction, a hybrid population will show genome-wide associations among alleles and genotypes from each phylogroup even after hundreds of generations of interbreeding. In contrast to this expectation, no consistent significant deviations from linkage and Hardy-Weinberg equilibria were found. Samples from both lakes did show significant disequilibria but they were limited to individual loci and were not concordant between populations, and were not robust to the method used. The single consistent association can be attributed to physical linkage between two microsatellite loci. Thus, results of our study support the hypothesis of free interbreeding between the two phylogroups of tench. Therefore, although the phylogroups may be considered as separate phylogenetic species, the present data suggest that they are a single species under the biological species concept.

The vendace (Coregonus albula L.) inhabits several Latvian lakes. In Latvia this species is included into the list of specially protected species with limited use. Taking into consideration the high variability of vendace and the fact that it belongs to valuable and marketable fish, there arises a scientific interest to reveal possible reasons influencing its variability. There is no precise scientific data on the local vendace populations and its biology and this hampers the rational usage of this fish and possibilities of its reproduction in Latvian lakes.In the present work the genetic polymorphism and the structure of vendace populations in Rāznas, Nirzas and Sventes lakes in Latvia have been defined based on the analysis of isoenzyme systems and RAPD markers. The genetic variability and population structure both within and among vendace populations have been studied. The activity of eight isoenzyme systems was studied and 16 loci were selected for genetic analysis. Eight of them were polymorphic and used for the statistical analysis. Also, 60 decanucleotide (RAPD) primers were tested. For the analysis, eight decanucleotide primers were used.The average level of isoenzyme polymorphism in vendace populations from three lakes was 41.67%. The diversity of alleles based on allozyme data in the studied populations was approximately the same. Data of RAPD analysis showed that Coregonus albula populations from the studied lakes were highly polymorphic.The results of this study indicate that the estimated intraspecific variation may be more pronounced with RAPD markers than with allozymes when the two approaches were applied to the same populations.
