R., Davies, G. D., Brazier, M., 2010. De nombreuses introductions ont été réalisées au cours de la seconde partie du XIXe siècle dans le cadre … 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. Mareš, J., Wognarová, S., Spurný, P., 2003. Risk identification and assessment of non-native freshwater fishes: concepts and perspectives on protocols for the UK. Water and Environment Journal, 20(4):233-239. http://www.blackwell-synergy.com/loi/wej. Krmiva, 37(3), 129-134. There is a risk that wels catfish may impact on native fauna for a number of reasons. However the species still accounts for only a small percentage of European freshwater aquaculture. S. glanis was introduced to the UK and western Europe in the nineteenth century. 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. Habitat principal. One or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. 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. Gozlan et al. Studies on wels catfish (Silurus glanis) development during cold season as an auxiliary species in sturgeon recirculated aquaculture systems. The sexual cycles of the catfish S. glanis, pike E. lucius, perch P. fluviatilis and pike-perch L. lucioperca. 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.

Copp et al. There are 100 species from 12 genera in the family. Diet varies with age and size, with smaller catfish foraging on invertebrates, while larger catfish >120 cm are able to exploit a broader niche, including fish and wildfowl. 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. 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. Tête aplatie, 6 barbillons très sensibles. Some example maps demonstrate the extent of introductions. Copp G H, Britton J R, Cucherousset J, García-Berthou E, Kirk R, Peeler E, Stakėnas S, 2009.

Effect of stocking density and three various diets on growth and survival of European catfish (Silurus glanis L.) larvae under intensive rearing condition. 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. European catfish S. glanis early feeding with four starters and zooplankton. Fischokologie, 6:7-20, Kottelat M, Freyhof J, 2007. 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).

S. glanis is the largest-bodied European freshwater fish. Thème : Le silure glane . Reviewers' names are available on request. The species sometimes enters brackish water in the Black Sea and Baltic Sea (Froese and Pauly, 2012). 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. Pesticides should always be used in a lawful manner, consistent with the product's label. Life span is normally 15-30 years, with a maximum recorded age of 80 years (Kottelat and Freyhof, 2007). Evaluation of production efficiency of selected feed mixes of intensive culture of European wels (Silurus glanis L.). In an initial invasiveness assessment, Copp et al.

Les premières introductions ont commencé au milieu du 19ème siècle. Acta Ichthyologica et Piscatoria, 27(1), 41-50. 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). http://www.fishbase.org. Preliminary studies of intensive wels catfish (Silurus glanis L.) and sturgeon (Acipenser sp.) (Die westliche Verbreitungsgrenze des Welses, Silurus glanis, an Rhine und Elbe.)

In adults, the gonads are 9-15% of total body weight. Body colour is variable but normally dark greenish-black with creamy yellow sides creating a mottled effect.They are solitary, predatory, opportunistic scavengers that hunt for stragglers (Boujard, 1995; Copp et al., 2009; Britton et al., 2010). Weight and linear growth of wels (Silurus glanis L.) up to one month of age in aquarium rearing. 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. Ameiurus melas (Rafinesque, 1820), le poisson chat : il possède deux nageoires dorsales dont la seconde est adipeuse, et quatre paires de barbillons. Incubation lasts about 50 hours at 24°C.

Age and growth of the European catfish (Silurus glanis) in a Turkish Reservoir and comparison with introduced populations. The culture of the European catfish S. glanis in the Czech Republic and in France. 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). Journal of Applied Ichthyology, 23:654-660, Carol J, Zamora L, García-Berthou E, 2007. Après avoir fécondé la femelle, le mâle reste deux jours avec elle … Habitat et comportement. S. glanis is listed as Least Concern (LC) in the IUCN Red List of Threatened Species (http://www.iucnredlist.org/). Its greater production in Bulgaria has been suggested (Hadjinikolova et al., 2010). The tiny dorsal fin on its upper body, rounded caudal fin and strong upper body assist the swimming motion. 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. Consumption of food sources is related to gape size with the larger catfish >120 cm in length consuming aquatic wildfowl and mammals in comparison to smaller counterparts of <30 cm feeding on invertebrates and molluscs. Rome, Italy: Food and Agriculture Organization of the United Nations. 2002; Muscalu et al. Des légendes évoquent des specimen atteignant les 5 m ou engloutissant des enfants. The risks to native species are through disease and parasite transmission, competition for benthic habitats and predation. 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). Some of the environmental impacts of the species (see the Environmental Impact section) might have economic effects.

Molecular Ecology, 8(11):1964-1966, Linhart O, Stech L, Svarc J, Rodina M, Audebert JP, Grecu J, Billard R, 2002. 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). Congélation possible à réception. 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. Wels catfish is the largest fish of the order Siluriformes and can attain a maximum length of 500 cm, although it more commonly reaches 300 cm. On peut trouver les cousins du silure jusqu'en Asie du Sud-est.

Larval and juvenile stages of introduced fish are most susceptible to predation due to small size (Gozlan et al. The large size suggests high potential for dispersal (Copp et al., 2009), although the limited available information on movement and migration suggests that the species demonstrates considerable site fidelity (Carol et al., 2007). The species is an effective ambush predator of slower moving Cyprinid species (Copp et al., 2009). Hydrobiologia, 671:259-265. http://springerlink.metapress.com/content/1573-5117/, Boeseman M, 1975.

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). Le silure est originaire d’Europe centrale. 2011; Syväranta et al. Currently, wels catfish are predominantly found in the South East and Midlands areas of the UK. Rearing of European catfish (Silurus glanis L.) to marketable size in warm water at the laboratory scale. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Oxford, UK: Fishing News Books, 46-57, Slavík O, Horký P, Bartoš L, Kolárová J, Randák T, 2007. Reproduction is controlled by environmental cues, e.g. Description : Le corps du silure glane est long et puissant ressemblant à celui du poisson chat. (2002), S. glanis has been farmed historically in Austria, Bulgaria, Croatia, Germany, France, Hungary, Greece, Macedonia, Poland, the Czech Republic and Romania. 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). 2009).

Colossal aggregations of giant alien freshwater fish as a potential biogeochemical hotspot. 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). Physiology & Behavior, 58(4):641-645, Boulêtreau, S., Cucherousset, J., Villéger, S., Masson, R., Santoul, F., 2011. 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. Auteur : B.

Maximum reported age is 80 yrs (Kottelat and Freyhof, 2007), although life span is commonly 15-30 yrs. 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.

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. Aquaculture: a biotechnology in progress: volume 1. International Conference: Aquaculture Europe, Amsterdam, Netherlands, 2-5 Jun 1987. However it still accounts for only a small percentage of European freshwater aquaculture compared with the main species, rainbow trout (Oncorhynchus mykiss), brown trout (Salmo trutta) and common carp (Cyprinus carpio) -- total production of S. glanis was 602 tonnes in 1993, increasing to 2000 tonnes in 2002, and has since stabilised at >700 tonnes/year. of coldest month > 0°C and < 18°C, mean warmest month > 10°C, Cf - Warm temperate climate, wet all year, Warm average temp.
