“…Within this region, three phylogeographical groupings, namely the Danubian, the Atlantic and the Adriatic, have been detected. However, a major part of the Black Sea populations that have been studied belongs exclusively to the Danubian grouping (Osinov & Bernatchez, 1996;Togan et al, 1996;Bernatchez, 2001). Togan et al (1995) found fixed differences at three allozyme loci between two populations of the Black and Mediterranean Sea basins.…”

“…In their preliminary study, the authors suggested that the Black Sea brown trout population of Turkey belongs to an undescribed phylogenetic group lying between the Danubian and Mediterranean groupings. However, most of the Turkish brown trout populations have been included in the Danubian grouping (Bernatchez, 2001). The genetic and phylogenetic status of many populations in Turkey and its neighbouring Balkan and Black Sea countries, and Iran, remain to be confirmed using molecular techniques.…”

“…The brown trout (Salmo trutta L.) displays a high level of genetic diversity in its native range in Europe (Bernatchez 2001;Cortey et al 2004). In France, both Mediterranean (MED) and Atlantic (ATL) brown trout populations show a clear genetic distinction at mitochondrial and nuclear genes (Guyomard 1989;Bernatchez et al 1992;Launey et al 2003).…”

In the native range of the brown trout (Salmo trutta L.) in Europe, the hybridization of native populations by nonnative domesticated strains introduced by stocking is one of the most serious threats to the long-term conservation of diversity within this species. With the objective of conserving and restoring the native gene pool, fishery managers are beginning to implement various management strategies at the local scale. Nevertheless, few case studies have been published that investigate the effectiveness of the various different conservation strategies for native brown trout populations. In the Chevenne Creek, a small French mountain stream, we tested the strategy of removing nonnative individuals by multiple electrofishing carried out by fishery managers in order to evaluate its feasibility and effectiveness for eliminating a nonnative population threatening a native population. Electrofishing produced major reductions in the nonnative population between 2006 and 2009, with 82-100% of nonnative individuals being removed over a period of 4 years. Nevertheless, despite multiple-electrofishing campaigns, this nonnative population was not entirely eradicated, and some natural recruitment persisted. The young of the year and subadults were less effectively removed than the adults. The results suggest that repeated electrofishing campaigns can be used by managers to reduce the nonnative brown trout population with the objective of conserving the native gene pool, but the removal operation must be continued for at least 4 consecutive years. This strategy, which is feasible in small streams, has to be followed by complementary operations to allow the restoration of a new, native, self-sustainable brown trout population.

1. Brown trout (Salmo trutta) is an important conservation resource in the Iberian Peninsula. The Atlantic is considered the most hydrologically stable region for the species, although inner Galicia (NW Spain) shows Mediterranean (unstable) climatic conditions. The Galician region, threatened by past releases of brown trout individuals from central European origin, harbours two native lineages, one of them endemic to the Iberian Peninsula. These populations are thus highly valuable for conservation, as well as being important for recreational fisheries. 2. In total, 546 individuals from 16 sampling sites (15 natural locations from inner Galicia and one from a central European hatchery stock) were genotyped for 11 nuclear markers (10 microsatellite loci and the LDH‐C* locus) to analyse genetic variability, population structure and introgression impact from stocking in order to assess the conservation status of brown trout in the region. Moreover, correlation among hatchery introgression and environmental variables relevant for species population dynamics was also investigated. 3. Genetic variability was within the range of Iberian brown trout (He = 0.500–0.600). Stocking impact was higher than previously reported values for the Atlantic region and was related to environmental instability. Highly significant native population differentiation was observed in the whole region (FST = 0.283), at least four main genetic groups being detected across the geographic distribution studied. 4. Conservation strategies at local level (including the creation of genetic refuges and temporal monitoring of genetic composition) are suggested to agencies and administrations for the sustainable management of brown trout.
