Artificial propagation and stocking of brown trout is a standard practice in recreational fishery management. In recent decades, the importance of maintaining intraspecific diversity and protecting locally adapted lineages has been recognized for the species' long-term survival. The first step in selecting donors for stocking involves distinguishin...

The genetic identity and conservation status of lake ecotype of brown trout (Salmo trutta) populations in Slovenia's Alpine lakes Bled and Bohinj have been subjected to changes due to historical stocking practices. We aimed to evaluate the genetic differentiation and origins of these populations to advise for correct conservation strategies. Using...

Aim Paleohydrological dynamics are well‐documented for European river systems, promoting shifting phases of isolation and connectivity of their aquatic fauna. These conditions coupled with high rates of hybridisation found in freshwater fishes may introduce considerable complexity and potential mito‐nuclear discordance of phylogenetic patterns. We...

1. The middle part of the Sava River in Slovenia provides one of the longest free-flowing habitats for huchen, a threatened species that is also protected by the European Habitats Directive. However, there are plans for the construction of a chain of hydropower plants along this stretch of river. It has previously been assumed that huchen is no lon...

Using nuclear DNA sequences we studied the phylogeny and genetic structure of trout in Morocco, and estimated the impact of stocking upon natural populations. We supplemented the sample set from a previous study with new sample localities and with specimens from the main hatchery in Morocco. Phylogeny was performed using Bayesian inference, identif...

The sculpins Cottus metae and C. scaturigo have previously been distinguished morphologically from C. gobio and described as distinct species. In the present study, sculpin samples from numerous sites covering the proposed range of C. metae and C. scaturigo, including unexamined adjacent sites that include topotypic specimens and other sculpins, we...

In 1848, the grayling Thymallus aeliani (Valenciennes) was described from Lake Maggiore, Italy, in the north Adriatic basin. Genetic analyses of the mitochondrial control region showed a unique evolutionary history of grayling inhabiting the rivers of northern Adriatic basin, from the upper reaches of the Po River and its left tributaries in the we...

European bullhead sensus lato is a species complex, in which lineage determination based on morphology has proven to be extremely difficult, probably due to low interspecific and high intraspeciefic morphological variation. Therefore, major evolutionary lineages across Europe have been determined based on molecular data, which also to some extent c...

The evolutionary relationship of grayling populations from the Kama and upper Ural drainage was studied, and the genetic diversity of the local populations was assessed. The complete mitochondrial DNA control region was sequenced and 12 microsatellite loci genotyped. Five previously undescribed closely related haplotypes (Caspian clade) were detect...
