“…To identify introductions of non-native brown trout stocks, we amplified and analyzed the CR or D-loop that has been proven to be a good phylogeographic and taxonomic marker (Bernatchez et al, 1992;Cortey and García-Marín, 2002;Tougard et al, 2018). It is used for a range of purposes in combination with other molecular markers, including determining implication for conservation and management (Vera et al, 2011), migrating strains (Habibi et al, 2013), and analyzing the consequences of stocking (Škraba et al, 2017).…”

The diversity of native trout fish Salmo spp. comprises a variety of nominal taxa in Serbia, Montenegro, and Bosnia and Herzegovina. Recent mapping of the resident trout populations detected the presence of brown trout Salmo trutta (sensu stricto) of the Atlantic (AT) mtDNA lineage introduced into populations of both tentative Danubian trout Salmo labrax and of tentative Adriatic trout Salmo farioides belonging to the Danubian (DA) and Adriatic (AD) mtDNA lineages, respectively. Introduction of the tentative Macedonian trout Salmo macedonicus of the AD lineage was also detected in a native population of the tentative S. labrax. In almost all recipient nonmigratory trout populations, a cross-breeding between native and introduced trout was detected by heterozygosity in either only the LDH-C nuclear locus or the LDH-C and specific microsatellite loci. The only exception was a population where both resident and migratory, lake-dwelling individuals of the tentative Adriatic trout spawned in a downstream section of a stream in Montenegro, as no microsatellite alleles of Atlantic brown trout that had been introduced upstream were detected. The occurrence of cross-breeding between Adriatic and brown trout was evident in the isolated, upstream section. It appears that migrating, lake-dwelling Adriatic trout in combination with their resident, stream-dwelling conspecifics suppress the introgression of genes from those situated upstream. In this regard, consideration should be given to the occurrence of the migratory brown trout in the Danube River at the broader Iron Gate Gorge area. They migrate in late summer and early fall from the Iron Gate One reservoir to the lower sections of tributaries devoid of any trout fish. However, some of these streams house very special native trout of the DA lineage in their short-extending upper sections. These native trout populations are, so far, still out of contact with the reservoir-dwelling trout. However, given the resilience of trout and their migratory life history, the outcome of this introduction could be deleterious for those native fish that are very precious in the conservation sense.

“…Although, based on the observed sea catch it seems that S. caspius has not yet been recovered properly and considered endangered at the national level [11]. There are two morphotypes of S. caspius based on the seasonal breeding, namely fall and spring breeders between October-November and March-April, respectively, however molecular investigations did not prove the significant differentiation and less is known about the morphology differences between these two forms [12].…”

Salmo caspius Kessler, 1877 is one of the most commercially important species of Salmonidae in the southern basin of the Caspian Sea. The occurrence of its wild populations has undergone sever reduction during the last years. In spite of the yearly restocking activity, still no progress on the recovery of its wild population has been observed. Hence, the present study was done in order to assess the efficiency of the current restocking activity in the southern Caspian basin in term of genetic diversity. DNA extracts of 32 S. caspius from four different groups were screened using 62621 genome-wide single nucleotide polymorphisms (SNP). The overal genetic diversity and Fst values were 0.18 and 0.08, respectively. Considering the observed admixture pattern and the positive values for inbreeding coeficient it seems that S. caspius suffers from its small effective population size. In order to obtain the maximum performance, alonside with expanding the size of brood stocks, rehabilitation of the habitats and spawning rivers of this nationally endangered species is of great importance.

“…Molecular markers, such as mtDNA D-loop and cytochrome b, microsatellites, RFLP (Restriction Fagments Length Polymorphism) and AFLP (Amplified Fragments Length Polymorphism), were recently used in a variety of investigations regarding brown trout. These include evolutionary and population-genetic studies (Zhang and Hewitt, 2003), phylogeography (Bernatchez, 2001;Cortey et al, 2002Cortey et al, , 2004, effects of stocking, conservation and management of populations and species (Apostolidis et al, 2008;Vera et al, 2010b;Kohout, 2012Kohout, , 2013, identification of migrating strains (Habibi et al, 2013) and resolving of the taxonomy-regarding confusion (Apostolidis et al, 2011;Mrdak et al, 2012). Mitochondrial DNA (mtDNA) has a number of characteristics that makes it a valuable molecular marker for evolutionary and population-genetic structure studies (Zhang and Hewitt, 2003).…”

Brown trout Salmo trutta wild stocks sustain a remarkable angling and hatchery-reared fish stocking pressure in waters of Serbia, where four drainage-specific and indigenous mitochondrial DNA haplotypes were reported for the drainage area of the Danube River basin. One of these mitochondrial DNA haplotypes, Da23b, was exclusive for brown trout in headwaters of the Crni Timok River (Grand Timok River system, Eastern Serbia). After its discovery in 2003, brown trout stocking was completely halted and abandoned, and a strict Catch-and-Release fishing regime was issued. However, failure of this regime due to enforcement resulted in decline of brown trout fishery. On checking the aboriginality of brood fish sampled in three headwater forks for artificial brown trout propagation, a novel, drainage-specific mtDNA haplotype was recorded in 54% of brown trout. It was assigned Da23c, due to its similarity (substitutions at the two variable sites) to the hitherto known haplotypes of Da23 group. Its finding and absence of Da23b haplotype imply an oversight in earlier haplotype determination. Incorporation of the non-indigenous haplotypes Da2 and Da-s1, introduced in the area by stocking before 2003, into the gene pool of native brown trout and declining of the latter's stock imposes the need for the more stringently enforced conservational activities (genotyping of each brood fish involved in artificial propagation) and improved fisheries management (Catch-and-Release) in the area.
