“…This is supported by the breeding behavior of the weather loach, which prefers warm water rich in vegetation, similar to the conditions in this pond. While weather loach eggs and larvae have never been reported in Denmark (Møller et al, 2012), the breeding season in other European countries is between April and June (Hartvich et al, 2010) and it is therefore reasonable to presume that the eDNA sampling done in May corresponded to the breeding season of the local population. Interestingly, Spear et al (2015) found that eDNA concentrations for the Eastern hellbender (Cryptobranchus alleganiensis alleganiensis) increased markedly during the breeding season, both in natural river systems and in an aquarium setting with a captive male hellbender.…”

“…A good example is the European weather loach Misgurnus fossilis, a species of international conservation concern (Council of the European Union, 1992) that has declined rapidly across its range (Hartvich et al, 2010), and is nearly extinct in Denmark (Møller et al, 2012). Drainage channels are an important habitat of the weather loach in modern-day Europe, where oxbows, backwaters, swamps and periodically flooded pools and meadows -the natural habitats of the weather loach (Lelek, 1987) -are rare.…”

a b s t r a c tThe European weather loach (Misgurnus fossilis) represents one of many European freshwater fishes in decline. Efficient monitoring is essential if conservation efforts are to be successful, but due to the species' cryptic biology, traditional monitoring methods currently in use are inefficient, time consuming and likely prone to non-detection error. Here, we investigate the usefulness of environmental DNA (eDNA) monitoring as an alternative or supplementary method for surveying the Danish weather loach population, which is presumed to consist primarily of a single group of no more than 50 individuals. In 2008, the majority of historical Danish localities were surveyed, using traditional fishing techniques. We then applied eDNA methods to a number of these, as well as other potential localities. We successfully detected the weather loach at multiple sites in the single known remaining locality; a result that was later confirmed when local managers caught eight live specimens. Furthermore, the eDNA method indicated presence of the weather loach in another historical locality, where the species has not been observed since 1995. At the remaining localities, weather loach eDNA was not detected, providing further evidence for its absence. Importantly, the eDNA survey required less effort in person-hours and lower costs than the traditional fishing survey. This study confirms that eDNA monitoring is a valid supplement to traditional monitoring methods currently applied to monitor rare freshwater fishes. We propose that by providing reliable distribution data at lower cost and limited effort, the eDNA method can allow for increased management efficiency of endangered freshwater species such as the European weather loach.

“…Despite its adaptation to oxygen deficient habitats ( M . fossilis has the ability for cutaneous respiration and oxygen uptake via its gut), it has exhibited a distinctive decline in many regions (Hartvich et al ., ). As a result, the species is listed as vulnerable or nearly extinct across its original range, including Germany, Hungary, Czech Republic, Slovenia, Austria, Switzerland, Slovakia and Denmark (Zulka & Wallner, ; Haupt et al ., ; Sigsgaard et al ., ).…”

“…The European weatherfish Misgurnus fossilis (L. 1758) has a wide distribution throughout Europe; originally ranging from north-west France to western Russia (Lelek, 1987;Kottelat & Freyhof, 2007). Primary habitats are oxbows, backwaters and periodically flooded meadows, all containing muddy sediments and aquatic vegetation (Pekárik et al, 2008;Hartvich et al, 2010).

Thermal requirements of larval weatherfish Misgurnus fossilis were investigated in terms of growth, survival and aerobic performance. Growth and survival of M. fossilis larvae acclimated to five temperatures (11, 15, 19, 23 and 27° C) were measured over 25 days. In the upper temperature treatments (19, 23 and 27° C), survival of larvae was stable throughout the entire rearing period (>75%), whereas 11 and 15° C resulted in severe declines in survival (to <10%). Growth of larvae (expressed as dry mass and total length) was highest at 19 and 23° C, but significantly decreased at 27° C. Routine metabolic rate of 3 days post-hatch larvae was estimated as oxygen consumption rate (ṀO ) during acute exposure (30 min to 1 h) to seven temperatures (11, 15, 19, 23, 27, 31 and 35° C). Larval oxygen uptake increased with each consecutive temperature step from 11 to 27° C, until a plateau was reached at temperatures >27° C. All larvae of the 35° C regime, however, died within the ṀO measurement period. M. fossilis larvae show greater than expected tolerance of high temperatures. On the other hand, low temperatures that are within the range of likely habitat conditions are critical because they might lead to high mortality rates when larvae are exposed over periods >10 days. These findings help to improve rearing conditions and to identify suitable waters for stocking and thus support the management of re-introduction activities for endangered M. fossilis.

“…In contrast to the globally expanding Oriental Weatherfish, Misgurnus fossilis (Linnaeus, 1758) is a species of international conservation concern (Council of the European Union, 1992, listed in Annex II of the European Habitat Directive) facing rapid population declines across its European range (Hartvich et al, 2010;Freyhof, 2013). Its original distribution range covers Central and Eastern Europe from Northern France to the River Volga in the east, including the entire Danube River basin (Lelek, 1987;Banarescu, 1990).…”

-The Oriental Weatherfish is considered a globally invasive fish species. In Europe, several reported feral populations of Oriental Weatherfish display an overlapping distribution range with native weatherfish Misgurnus fossilis, a declining species of international conservation and aquatic management concern. Morphologically distinguishing the different weatherfish species can be difficult, as their coloration is highly variable, many species reveal high phenotypic plasticity, and morphological traits like coloration might be not obvious or might be degraded during field sampling and after preservation. Herein, we analysed suspicious weatherfish specimens from southern Germany, demonstrating the usefulness of molecular genetic species identifications in this genus. We present the first molecular genetic species record of Misgurnus anguillicaudatus in Central Europe, and confirm the range expansion of Oriental Weatherfish into the river Inn catchment in southern Germany. As accurate species identification is crucial both in the context of monitoring and conserving native endangered species, and in early detection and prevention of biological invasion, we suggest the standard use of genetic species identification if morphological traits are not obvious.Keywords: Misgurnus anguillicaudatus / Misgurnus fossilis / DNA barcoding / genetic species identification / biological invasion Résumé -Identification génétique des espèces de loche et première confirmation moléculaire de la présence de la loche baromètre Misgurnus anguillicaudatus (Cantor, 1842) en Europe centrale. La loche baromètre est considérée comme une espèce de poisson globalement invasif. En Europe, plusieurs populations sauvages signalées de la loche baromètre présentent une aire de répartition en chevauchement avec la loche d'étang indigène locale Misgurnus fossilis, une espèce en déclin, objet de conservation internationale et de gestion aquatique. La distinction morphologique des différentes espèces de loches peut être difficile, car leur coloration est très variable, de nombreuses espèces révèlent une forte plasticité phénotypique, et les traits morphologiques comme la coloration pourraient ne pas être évidents ou pourraient être dégradés lors de l'échantillonnage sur le terrain et après la conservation. Nous avons analysé les spécimens douteux du sud de l'Allemagne démontrant l'utilité des identifications génétiques moléculaires des espèces dans ce genre. Nous présentons les premières données d'identification génétique de l'espèce Misgurnus anguillicaudatus en Europe centrale et confirmons l'expansion géographique de la loche baromètre dans le bassin hydrographique de la rivière Inn dans le sud de l'Allemagne. Étant donné que l'identification précise des espèces est cruciale tant dans le contexte de la surveillance et de la conservation des espèces indigènes en voie de disparition, que dans le dépistage précoce et la prévention de l'invasion a These authors made equal contributions to this work.
