“…Establishment of all populations of F. limosus in Europe can be traced back to the introduction of only 90 individuals (Filipová et al, 2011), underlining the fact that even if only a few individuals remain after a control measure this can be sufficient enough to build up the population again (Henttonen and Huner, 1997). For marbled crayfish (Procambarus virginalis Lyko, 2017), a species which reproduce by parthenogenesis, it is theoretical even possible to rebuild a population with only one individual (Ercoli, 2019). In this case, the probability of extinction is again much higher due to environmental factors, predation and failure to breed.…”

Invasive crayfish species were first documented in Switzerland in the 1970s. Today, North American crayfish species dominate in most major lakes and streams in Switzerland. In combination with the crayfish plague, they pose a substantial threat to our native crayfish. Over the past 20 years, various techniques have been applied to reduce negative impacts of these invasive crayfish in Switzerland: eradication (temporary drainage or destruction of a water system, biocides), suppression (intensive trapping, electricity introduction of predatory fish) and containment (construction of crayfish barriers). Temporary drainage or filling-in of isolated ponds, in combination with calcium hydroxide application has been successful in eradicating populations of invasive crayfish. However, trapping and introduction of predatory fish led to a reduction in population density but neither method has ever caused the extinction of a population. Invasive crayfish have not yet reached crayfish barriers, therefore, long-term functionality of these barriers still needs to be proven. Nevertheless, functional controls with native crayfish have shown that barriers prevent their upstream movement. Implementation of crayfish barriers is the most promising method to protect native crayfish from displacement by invasive crayfish species. Many measures are expensive, time consuming, and show little or no success in controlling invasive crayfish. Therefore, we recommend to focus on implementing drastic measures, such as filling-in or draining of isolated waters or a combination of various methods to maximise the reduction of population size.

“…This is exemplified by the situation in Madagascar, where the animals were first detected around 2006 20 , 21 , and have now populated an area of 100,000 km 2 that encompasses many diverse habitats 18 , 22 . Isolated wild populations have also been described in Germany and in several other European countries 23 – 29 , but their genomic variation has not been analyzed yet.…”

The marbled crayfish (Procambarus virginalis) represents a very recently evolved parthenogenetic freshwater crayfish species that has invaded diverse habitats in Europe and in Madagascar. However, population genetic analyses have been hindered by the homogeneous genetic structure of the population and the lack of suitable tools for data analysis. We have used whole-genome sequencing to characterize reference specimens from various known wild populations. In parallel, we established a whole-genome sequencing data analysis pipeline for the population genetic analysis of nearly monoclonal genomes. Our results provide evidence for systematic genetic differences between geographically separated populations and illustrate the emerging differentiation of the marbled crayfish genome. We also used mark-recapture population size estimation in combination with genetic data to model the growth pattern of marbled crayfish populations. Our findings uncover evolutionary dynamics in the marbled crayfish genome over a very short evolutionary timescale and identify the rapid growth of marbled crayfish populations as an important factor for ecological monitoring.

“…Considering the high interest in the marbled crayfish from aquarists, their presence in European ecosystems is probably due to the voluntary release into the wild carried out by some owners and traders [ 32 , 33 , 34 , 35 , 36 , 37 ]. To date, stable populations of P. virginalis in Europe are known from: Germany and Netherlands [ 10 ], Croatia [ 38 ], Romania [ 39 ], Slovakia [ 40 ], Estonia [ 41 ], Czech Republic [ 42 ], Hungary [ 43 ], Ukraine [ 44 ], and Sweden [ 45 ]. The spread of this species is not limited to Europe, in fact its presence has been also reported in Japan [ 46 ] and Madagascar [ 29 , 47 ].…”

In the fresh waters of Sardinia (Italy), the non-indigenous crayfish species Procambarus clarkii has been reported from 2005, but, starting from 2019, there have been several reports of a new non-indigenous crayfish in southern and central areas of this Mediterranean island, and its morphology suggests that this species may be the marbled crayfish Procambarus virginalis. Forty-seven individuals of this putative species were analyzed, using the mitochondrial gene Cytochrome c Oxidase subunit I as molecular marker to identify this crayfish and investigate the level of genetic variability within the recently established population. Phylogenetic and phylogeographic analyses were carried out on a dataset including sequences from the Sardinian individuals and from all congenerics available in GenBank. Results showed that the new Sardinian crayfish belong to the species P. virginalis. All the sequences belonging to P. virginalis from European countries are identical, with only few exceptions found among Sardinian individuals. In conclusion, this paper highlights the occurrence of a new further alien species in the Sardinian fresh waters, which are already characterized by the high presence of non-indigenous species.
