Translocation and introduction of non-native organisms can have major impacts on local populations and ecosystems. Nevertheless, translocations are common practices in agri- and aquaculture. Each year, millions of wild-caught wrasses are transported large distances to be used as cleaner fish for parasite control in marine salmon farms. Recently, it was documented that translocated cleaner fish are able to escape and reproduce with local wild populations. This is especially a challenge in Norway, which is the world's largest salmon producer. Here, a panel of 84 informative SNPs was developed to identify the presence of nonlocal corkwing wrasse (Symphodus melops) escapees and admixed individuals in wild populations in western Norway. Applying this panel to ~2000 individuals, escapees and hybrids were found to constitute up to 20% of the local population at the northern edge of the species’ distribution. The introduction of southern genetic material at the northern edge of the species distribution range has altered the local genetic composition and could obstruct local adaptation and further range expansion. Surprisingly, in other parts of the species distribution where salmon farming is also common, few escapees and hybrids were found. Why hybridization seems to be common only in the far north is discussed in the context of demographic and transport history. However, the current lack of reporting of escapes makes it difficult to evaluate possible causes for why some aquaculture-dense areas have more escapees and hybrids than others. The results obtained in this study, and the observed high genomic divergence between the main export and import regions, puts the sustainability of mass translocation of nonlocal wild wrasse into question and suggests that the current management regime needs re-evaluation

Not that clean: Aquaculture-mediated translocation of cleaner fish has led to hybridization on the northern edge of the species' range

This is the final SNP dataset used in Faust et al. (2021) study "Not that clean: aquaculture mediated translocation of cleaner fish has led to hybridization on the northern edge of the species’ range" published in Evolutionary Applications.
There are two files. First one, named "genepop_all_sorted.gen" is the actual genotype data file in genepop format. 
It contains a header ("snp2gen-converted") followed by locus names (starting with "SYMME")and each individual genotype.
Samples from different populations are separated with "POP". Population names are shown in individual names and follow the names given in the paper in Table 1. Same table gives additional information of e.g. number of samples in each population.  
Accompanyig file named "ID_all_sorted.txt" is a text file giving population name (pop_name), used population code (pop_code), sample name (Sample_name), sample ID (sample_ID) and corresponding larger geograohic group (Group) for each sample in same order  as given in the genpop file
