Another reason for introductions is as a biocontrol agent for controlling cyprinid fish. Silure glane — Wikipédi . 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. To protect species or infer their invasiveness potential, it is necessary to understand the origin, genetic diversity and migration patterns. Oxford, UK: Fishing News Books, 46-57, Slavík O, Horký P, Bartoš L, Kolárová J, Randák T, 2007. The species is an effective ambush predator of slower moving Cyprinid species (Copp et al., 2009). Filipiak, J., Sadowski, J., Trzebiatowski, R., 1997. 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). 60:21-36. 2000). European catfish S. glanis early feeding with four starters and zooplankton. 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. Fish and Fisheries. Science (Washington), 290(5491), 516-518. doi: 10.1126/science.290.5491.516, Hickley P, Chare S, 2004. Acta Ichthyologica et Piscatoria, 27(1), 41-50. In: De Pauw, N., Jaspers, E., Ackefors, H., Wilkins, N, eds. 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.

[Cefas Science Technical Report No. 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). Consent is usually not granted for open waters, although enclosed waters are permitted (Britton and Pegg, 2007; Copp et al., 2009). … Impact potentiels. 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. Development of technological regimes of European catfish (Silurus glanis L.) growing in the ponds of Belarus. Migration to European rivers including the Danube, Dnieper and Volga was via the Caspian, Black and Aral seas. Spawning is nocturnal. According to Naylor et al.

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). Establishment may be more sporadic in northern countries such as Belgium and the UK where temperatures are less favourable (Elvira, 2001; Britton and Pegg, 2007). 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. S'il avait un temps quasiment disparu des rivières françaises, il a depuis été réintroduit et est notamment élevé pour la pêche, non sans controverse car son caractère vorace peut le rendre nuisible pour les autres espèces. 2011; Syväranta et al.

Homogenization dynamics and introduction routes of invasive freshwater fish in the Iberian Peninsula. The risks to native species are through disease and parasite transmission, competition for benthic habitats and predation. Prokeš, M., Baruš, V., Penáz, M., Hamácková, J., Kouril, J., 1999. 2003), and also overwintering mortality as S. glanis larvae are unable to survive low temperatures <13ºC (David, 2006; Copp et al.

S. glanis is in the lower range of the high risk score of FISK, although these scores are variable and likely to change in relation to the context of environmental factors affecting risk (Copp et al., 2005). Tête aplatie, 6 barbillons très sensibles. Preliminary studies of intensive wels catfish (Silurus glanis L.) and sturgeon (Acipenser sp.) 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. 1996; Ulikowski et al. S. glanis is cited as present in some rivers in the UK, e.g. It is the largest-bodied European freshwater fish (Copp et al., 2009).

Movement to new areas is generally through introduction for aquaculture and recreational fishing, or sometimes for biological control. Dès les années 1980 on s'intéresse au régime alimentaire du silure et à sa place dans le réseau trophique . Le silure glane aime les eaux chaudes, la température de son habitat doit faire au moins 20° C en été. The skin can be used in glue and leather manufacture. Activity peaks during the night, with nocturnal foraging motivated by hunger stimuli. C'est un super prédateur des rivières, opportuniste, adaptable et capable d'apprentissage. 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.

Voracious invader or benign feline? 3 paires de barbillons aux coins de la bouche dont une très longue. Le Silure glane n'est pas une espèce protégée, au contraire, il est considéré comme un parasite, vous n'avez donc pas besoin d'un permis pour le pêcher. Is European catfish a threat to eels in southern France? Some example maps demonstrate the extent of introductions. (2003) reported that more than 50% of successful invasive fish species introduced into the UK exhibit parental care, where fish actively protect and guard their eggs or larvae and defend territories. Le silure peut atteindre 2,60 m pour un poids de 100 kg (Individu de 2,11 m pêché en Meuse). Habitat use follows a daily pattern, and incorporates territorial behaviour. 2002; Ulikowski et al. Fonds des eaux profondes et calmes des fleuves et rivières d'Europe jusqu'au centre de l'Asie. The anatomy and location of fins and body shape of S. glanis indicate that this fish is a demersal species, with a powerful pair of pectoral fins that is positioned behind the gills at the base of the ventral fins, small pelvic fins situated by the anal vent and an elongated anal fin that is over 50% of its body length. River Thames, River Great Ouse, where its presence is yet to be proved (Copp et al., 2007). Contribution of anadromous fish to the diet of European catfish in a large river system.

Native to eastern Europe and western Asia it is now established in several countries to the west and south of its native range. Introduction of S. glanis for aquaculture and enhancement of sport angling is common. Each gram of ova has about 195 eggs prior to spawning. GISD/IASPMR: Invasive Alien Species Pathway Management Resource and DAISIE European Invasive Alien Species Gateway. (2001), aquaculture is the foremost transfer route of exotic fish species globally, which reflects the growth in aquaculture caused by the increasing demand for fish consumption which cannot be provided by wild fish capture alone.
