The wels catfish S. glanis is part of the family Siluridae, a group of freshwater fish native to Europe, Asia and Africa. Larval and juvenile stages of introduced fish are most susceptible to predation due to small size (Gozlan et al. However, there are reports of breeding in some lakes in southern England at present temperatures (Copp et al., 2009). Studies on wels catfish (Silurus glanis) development during cold season as an auxiliary species in sturgeon recirculated aquaculture systems.

Signalé pour la première fois en 1993 Environ 400 … Evolution de son aire de répartition et prédiction de son extension. The diet of small juveniles is sometimes almost entirely invertebrates, but can also be composed of benthic or mid-water column organisms such as Chironomidae, and during their first year S. glanis take an increasing proportion of young-of-the-year (YoY) fish. 2009; Syväranta et al. National Marine Fisheries Service, S. glanis is the largest-bodied European freshwater fish. Their paired pelvic fins are each made up of one spine and 11-12 soft rays and have paired pectoral fins of one spine and 14-17 soft rays. Diurnal and seasonal behaviour of adult and juvenile European catfish as determined by radio-telemetry in the River Berounka, Czech Republic. 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). Habitat use follows a daily pattern, and incorporates territorial behaviour. Hendry, A. P., Wenburg, J. K., Bentzen, P., Volk, E. C., Quinn, T. P., 2000. PLoS ONE, 6(10), e25732. Le silure glane (Silurus glanis) est une espèce de poissons d'eau douce du genre Silurus, originaire du Paléarctique occidental. S. glanis was introduced to Netherlands from Hungary for this purpose.

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. Peu exigeant en revanche quand à la qualité et la teneur en oxygène, il évolue dans toutes sortes de milieux, pourvu que les eaux soient calmes ou faiblement courantes. 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. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. In the UK, wels catfish, because they are non-native, require an ILFA (Introduction of Live Fish Act) license for introduction as part of regulatory legislation control and enforcement.

However, consideration must be given to the economic costs that are likely to arise from management control policies with the removal of S. glanis from unlicensed waters; monitoring, removal costs and challenges in recapturing demersal species. 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. Some example maps demonstrate the extent of introductions. Aquaculture of this species is constrained by water temperatures <10ºC during winter months in some regions of Europe including France. 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. Copp et al. S. glanis is a warm water predatory fish with fast growth rate (Cirkovic, 2012); cultured fish can attain a mean length increment of >15cm TL within 4 months at optimum temperatures >26ºC (Hilge, 1989).

Secondly, catfish are opportunistic foragers, able to switch their feeding to the most suitable resource available. Average temp. Fast growth is advantageous for non-natives in minimising predation by quickly exceeding gape size of native predators, and in increasing foraging opportunities (Hendry et al.

Wels catfish exhibit parental care of young, and the males guard clusters of eggs adhered to woody tree roots and submerged macrophytes in riparian reaches and floodplains (Copp et al., 2009). Fisheries Management and Ecology, 14:263-268, Britton, J. R., Davies, G. D., Brazier, M., 2010. It appears to establish relatively easily after introduction, especially in warmer climates such as around the Mediterranean (Crivelli, 1995). (2002), S. glanis has been farmed historically in Austria, Bulgaria, Croatia, Germany, France, Hungary, Greece, Macedonia, Poland, the Czech Republic and Romania. (2009) indicated a narrower range between 25 and 28ºC. Life span is normally 15-30 years, with a maximum recorded age of 80 years (Kottelat and Freyhof, 2007). Mareš, J., Wognarová, S., Spurný, P., 2003. Impact potentiels. (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. It and Sander lucioperca are predatory fish that are traditionally reared to control wild forage fish dispersed during seasonal pond flooding that may be interspecific competitors with cyprinids (Bokor et al. The potential risk of hybridization with native species is likely to be limited to native Silurus species, such as the native congener S. aristotelis in Greece. 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. Aquaculture, 243(1/4), 323-329. http://www.sciencedirect.com/science/journal/00448486, Kinzelbach R, 1992. Handbook of European Freshwater Fishes. It is the largest-bodied European freshwater fish (Copp et al., 2009). Eggs are protected by mucous and stickiness.

Generate a print friendly version containing only the sections you need. The ecological trophic effect of S. glanis is unclear; some authors consider that the species can decimate tench (Tinca tinca) populations while others are of the view that as they are to some extent scavengers, their predatory impact may be benign rather than intense (Copp et al., 2009).

It is also established in Italy, Syria, Portugal, Croatia, Turkey, the UK, France, the Netherlands and China, although ecological impact here is unknown. Une partie de la mythologie et de la littérature sur le silure glane lui donne des proportions stupéfiantes, ce qui reste à établir scientifiquement, quand Aristote décrivait un poisson beaucoup plus petit, sans qu'il soit possible d'affirmer qu'il s'agissait bien de cette espèce. Wels catfish are distinguishable by an elongated scale-less, slime-covered body, with strong upper body strength and laterally flattened tail. 2008). Several studies have indicated that the temperature threshold for optimum growth may vary between 22 and 26ºC (Mazurkiewicz et al., 2008), or 23-30ºC (Ulikowski et al., 2003) whereas Copp et al.

Ressemblances et différences : reconnais les animaux en un clin d’œil ! 2001). Introduction of S. glanis for aquaculture and enhancement of sport angling is common. The risks to native species are through disease and parasite transmission, competition for benthic habitats and predation. The predicted increase of water temperatures of 2-3ºC by 2050 as a result of climate change is likely to amplify the risk of establishment and breeding success in the UK and other northern countries (Rahel and Olden, 2008; Britton et al., 2010).
