Deliberate introductions have also been followed by accidental escape and dispersal to other waters, as has been reported by Boeseman (1975) in the Netherlands, where it was introduced from Hungary. Dokuchaeva, S. I., 2011. Genetic structure and phylogeography of European catfish (Silurus glanis) populations. They can be identified by 6 barbels, 2 long ones on each side of the mouth and 4 shorter ones from the lower jaw. (2011) reported that in the Camargue in Southern France, S. glanis consumption was not a threat to eel distribution, as their diet was mainly omnivorous. Effects of the dietary protein and lipid levels on growth and body composition of bagrid catfish, Pseudobagrus fulvidraco. Removal of wels catfish from unlicensed lakes appears to be a priority for the Environment Agency in England and Wales, although how successful these measures are in practice has yet to be ascertained. Incubation lasts about 50 hours at 24°C. The flattened snout with spaced apart nostrils and long barbels on either side of the upper jaw, and 4 shorter barbels on the lower jaw, indicate that S. glanis sense their prey by highly sensitive chemical and olfactory sensors on their barbels and nostrils rather than by vision, as their eyes are small; this can be related to their benthic habitat ecology (Copp et al., 2009). © Copyright 2021 CAB International. Migration to European rivers including the Danube, Dnieper and Volga was via the Caspian, Black and Aral seas. S. glanis is robust enough during transport (even in minimal water and over considerable distances) to be translocated to areas outside its native geographical range (Copp et al., 2009).

They can also use holes or burrows of clay and muddy bottom substrate of lakes and ponds and are often hidden among dense macrophyte cover. However, many aspects of behaviour are still unknown, and Valadou (2007) suggests that virtually all aspects of the biology of introduced S. glanis require study.

Aquaculture development trends in Europe. Silure glane — Wikipédi . Wels catfish are also hosts of specialist parasites such as Trichodina siluri, Myxobolus miyarii, Leptorhynchoides plagicephalus and Pseudotracheliastes stellifer which may be detrimental to native fish survival (Copp et al.

Males have running milt 30-40 days before spawning and produce sperm for relatively long periods, with a gradual, extended duration of spermatozoa discharge (Shikhshabekov, 1978). Larval and juvenile stages of introduced fish are most susceptible to predation due to small size (Gozlan et al. It appears to establish relatively easily after introduction, especially in warmer climates such as around the Mediterranean (Crivelli, 1995). Although the genetic structure and phylogeography have been studied in its native range, there is little information known about the genetic characteristics of S. glanis in its introduced range (Copp et al., 2009). (2009) say that it is most common in the River Ebro, Spain, in the 130 km between its point of introduction in 1974 and the Ebro delta, and suggest that natural dispersal is likely to be slow and density dependent. Within these habitats the fish prefer benthic woody tree root habitats and stony crevices for refuge and cover. 2013, http://www.fao.org/figis/servlet/static?dom=collection&xml=dias.xml, Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License. 2001).

(2002) investigated the genetic structure of S. glanis across most of its natural distribution using 10 microsatellite loci. 2003), and also overwintering mortality as S. glanis larvae are unable to survive low temperatures <13ºC (David, 2006; Copp et al. Another reason for introductions is as a biocontrol agent for controlling cyprinid fish. Natural predators of S. glanis include otters (Lutra lutra), cormorants and waders, and other predatory fish such as pike (Esox lucius) and zander (Sander lucioperca). The sexual cycles of the catfish S. glanis, pike E. lucius, perch P. fluviatilis and pike-perch L. lucioperca. Wels catfish are carriers of viral pathogens, namely spring viraemia of carp (SVC) and European sheatfish virus (ESV), which may adversely impact native fish including salmonids and amphibians. In April 2012, accidental flooding from licensed lakes containing wels catfish into flood valleys of the River Colne and Chelmer in East Anglia were being investigated. Secondly, catfish are opportunistic foragers, able to switch their feeding to the most suitable resource available. Silure glane Poissons / Ostariophysien . The wels catfish S. glanis is part of the family Siluridae, a group of freshwater fish native to Europe, Asia and Africa. Preliminary telemetry data on the patterns and habitat use of European catfish (Silurus glanis) in a reservoir of the River Ebro, Spain. S. glanis has a broad omnivorous diet, including invertebrates and vertebrates such as small rodents. Following introduction outside its native range, the wels catfish has become established in Bosnia-Herzegovina, Spain, Denmark and Tunisia with some ecological effects. https://wcd.coe.int/com.instranet.InstraServlet?command=com.instranet.CmdBlobGet&InstranetImage=1338217&SecMode=1&DocId=1464096&Usage=2, FAO, 2012.

Aquaculture - a gateway for exotic species. Introductions to rivers in Spain have resulted in abundant populations in four river basins, where catfish can reach large sizes > 1 m (Carol et al., 2009). Use of frozen zooplankton in the intense rearing of European catfish (Silurus glanis L.) larvae. Routes of introduction of S. glanis include recreational angling, aquaculture and also use as a biological control agent for cyprinid fish, with certain pathways being more frequent in some countries; for example, the species is predominantly farmed in aquaculture in Italy, Romania, Poland and the Netherlands, but used mainly to enhance recreational angling in the UK. S. glanis is a popular fish among anglers because of its large size and relatively frequent capture. Pairing up of males and females commences during migration as they proceed to compete for best spawning grounds in the reach of the river and in heavily vegetated lakes. Consumer popularity of cultured S. glanis has remained low (Varadi et al. 2009). Ce comportement peut cependant évoluer exceptionnellement, comme mis en évidence par une étude sur des silures du Tarn chassant en pleine journée des pigeons venus s'abreuver sur les rives de la rivière ,  en se projetant hors de l'eau. The different routes of introduction are pertinent regarding release of non-native fish, as some routes such as angling have a greater risk of unregulated transfer activities from fishermen in unsupervised lakes. Other examples of depressed foraging activity and growth were reported at water temperatures <15ºC as fish were unable to metabolise food at temperatures <10ºC and were sedentary to minimise energy expenditure (Boujard, 1995). Consent is usually not granted for open waters, although enclosed waters are permitted (Britton and Pegg, 2007; Copp et al., 2009). > 10°C, Cold average temp. Diel rhythms of feeding activity in the European catfish, Silurus glanis. According to Linhart et al. Le silure glane. Some angling introductions are unregulated and illegal, with S. glanis transferred to unlicensed lakes in the UK that do not meet the ILFA (Import of Live Fish Act) criteria set by the Environment Agency because of risks concerning flooding and the likelihood of entry to nearby rivers. A review of the environmental biology of European catfish Silurus glanis in its native and introduced ranges. A model of isolation by distance seems more probable and a hypothesis of recent dispersion from only one glacial refugium around the Ponto-Caspian region is proposed. Il est originaire d'Europe centrale (Danube, Dniepr et Volga). Tête aplatie, 6 barbillons très sensibles.

The species was later introduced to Spain in the twentieth century and reintroduced to Belgium, Netherlands and France. Penil (2004) suggests that it may expand its range by movement in man-made canal networks. http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0050840 doi: 10.1371/journal.pone.0050840, Czarnecki, M., Andrzejewski, W., Mastynski, J., 2012.

Since 1975, it has been farmed for its meat in pond cultures in Italy and former Yugoslavia, and also in its native range in Hungary, Poland, Slovakia and Lithuania (and also Belarus -- Dokuchayeva, 2011) where it is considered an expensive meat delicacy. Current Frontiers in Cryopreservation, 13:254-267, Boujard T, 1995. Assessing the effects of climate change on aquatic invasive species. A potential beneficial ecological effect is that S. glanis can predate on signal crayfish (Pacifastacus leniusculus), which is an invasive species in Europe that is adversely effecting native crayfish populations (Carol et al., 2009; Copp et al., 2009).

Native populations extend from Germany to Eastern Europe including Poland and southern Sweden, and also from northern Iran and southern Turkey to the Baltic states and Russia, and to the Aral sea of Kazakhstan and Uzbekistan (Copp et al., 2009). (Hamáčková et al., 1993; Bogut et al., 1995; Filipiak et al., 1997; Mareš et al., 2003), but there is little data available about growth using forage fish as food in natural ponds (Zaikov et al., 2008; Cirkovic, 2012). Impact potentiels. Previous studies of cultured S. glanis in central and eastern Europe indicated that this species is capable of rapid growth in warm waters >20ºC (Linhart et al. The mitochondrial genome has 16,526 base pairs containing 37 genes, of which 13 genes are for protein synthesis, 22 tRNAs and 2rRNAs, and a control region which functions in the same way as other vertebrate mtDNAs. by Cowx, I. G.]. Growth is an integrating variable of fish physiology and behaviour, and reduced growth can result from a variety of factors: food abundance, fish age, social hierarchy, change in water temperature, habitat and increased energy expenditures (Zaikov et al. The routes used to introduce non-native fish species are closely related to the nature and extent of different anthropogenic activities such as aquaculture, research, pest control and also recreational fishing. The tiny dorsal fin on its upper body, rounded caudal fin and strong upper body assist the swimming motion. Since 1975, it has been farmed for its meat in pond cultures in Italy and former Yugoslavia, and also in its native range in Hungary, Poland, Slovakia and Lithuania (and also Belarus -- Dokuchayeva, 2011), where the species is considered an expensive meat delicacy. Overall, the tipping point temperature indicator for growth among cultured S. glanis appeared to be >20ºC and at these temperatures fish can gain ~ 4kg within 2yrs, in contrast to depressed growth at lower temperatures (Gullu et al. Journal of Applied Ichthyology, 23:654-660, Carol J, Zamora L, García-Berthou E, 2007. The sheer size of this fish has also attracted scuba-divers to some lakes where it has been introduced in the Netherlands (and probably elsewhere), which also generates local revenue.
