Oxford, UK: Fishing News Books, 46-57, Slavík O, Horký P, Bartoš L, Kolárová J, Randák T, 2007. However, there are reports of breeding in some lakes in southern England at present temperatures (Copp et al., 2009). Eggs are protected by mucous and stickiness.

Fontenay-sous-Bois, France: Conseil Supérieur de la Pêche, 92 pp, Varadi, L., Szucs, I., Pekar, F., Blokhin, S., Csavas, I., 2001. Le silure glane est un poisson d'eau douce originaire des pays de l'Est et notamment du Danube. 3 paires de barbillons aux coins de la bouche dont une très longue. Prokeš, M., Baruš, V., Penáz, M., Hamácková, J., Kouril, J., 1999. 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. Within these habitats the fish prefer benthic woody tree root habitats and stony crevices for refuge and cover. Il apprécie les eaux chaudes pour se reproduire. Reviewers' names are available on request. C'est le plus grand poisson d'eau douce d'Eurasie et le troisième plus grand au monde, pouvant atteindre plus de 2,7 m de longueur et 130 kg [1], [2]. Rapid evolution of reproductive isolation in the wild: evidence from introduced salmon. 2002; Ulikowski et al.

In their native range, catfish are under threat from anthropogenic changes including river modifications resulting in the loss of shallow spawning sites (Hamackova et al., 1997; Copp et al., 2005; Copp et al., 2007). Source : Zapping Sauvage. danger : le silure glane (Silurus glanis). Le silure glane est un poisson typique de l’Europe centrale. The species sometimes enters brackish water in the Black Sea and Baltic Sea (Froese and Pauly, 2012). There is intensive daytime use of littoral habitat, resting within dense vegetation (Copp et al., 2009). Animal sauvage France ... Habitat & répartition. Water quality and accelerated winter growth of European catfish using an enclosed recirculating system. The larvae live in the nest until the yolk sac is absorbed. The introduction of S. glanis in angling clubs is likely to increase revenue to local communities and generate business. 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). 2008; Muscalu et al. S. glanis is cited as present in some rivers in the UK, e.g. Introduction of S. glanis for aquaculture and enhancement of sport angling is common. Assessing the effects of climate change on aquatic invasive species. (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. Conservation Biology, 22(3):521-533. http://www.blackwell-synergy.com/loi/cbi, Rees EMA, 2010. Aquatic Living Resources, 15:139-144, Marcel J, 1980. 2001). Despite the great genetic differentiation of S. glanis populations, no consistent pattern of geographical structuring was revealed, in contrast to previous studies of European freshwater fish species. Festival teriaki 2015. Polish Journal of Natural Sciences, 23(4), 850-857. http://versita.com/science/agriculture/pjns/ doi: 10.2478/v10020-008-0008-0, Kim LeeOh, Lee SangMin, 2005. 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. 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. Ethologie du silure Un silure glane. 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. 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. When several references are cited, they may give conflicting information on the status. 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). Status and development tendencies of freshwater aquaculture production in Bulgaria.

Life span is normally 15-30 years, with a maximum recorded age of 80 years (Kottelat and Freyhof, 2007). 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. 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. The sexual cycles of the catfish S. glanis, pike E. lucius, perch P. fluviatilis and pike-perch L. lucioperca. Silure glane Présent toute l’année sur le bassin de Saulx Nom scientifique : Habitat : Le silure fréquente les canaux, les plaines et les grands lacs (zone des … PLoS ONE, 7(12), e50840. Aquaculture of this species is constrained by water temperatures <10ºC during winter months in some regions of Europe including France. There is one clear seasonal peak in spawning per year, between May and July. Options including draining of lakes, application of rotenone, capture of fish by fyke and seine netting, and electrofishing should be all reviewed in control management and risk assessment plans (Britton et al., 2009). This species requires temperatures of 25-28ºC for optimal growth, food assimilation and breeding (Copp et al., 2009). De nombreuses introductions ont été réalisées au cours de la seconde partie du XIXe siècle dans le cadre … Information regarding the wels catfish nuclear and mitochondrial genomes is sparse. Silurus glanis (wels catfish); line caught adult. Toward a global information system for invasive species. Des légendes évoquent des specimen atteignant les 5 m ou engloutissant des enfants. Perfectionniste psychologie. 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. Larval and juvenile stages of introduced fish are most susceptible to predation due to small size (Gozlan et al. Voracious invader or benign feline? Wels catfish are distinguishable by an elongated scale-less, slime-covered body, with strong upper body strength and laterally flattened tail. 1998; Zaykov and Hubenova-Siderova, 1998; Prokés et al., 1999; Grozev et al., 2000; Bogut et al., 2002; Paschos et al., 2004; Kim et al., 2005; Dediu et al., 2010; Alp et al., 2011; Jamróz et al., 2008; Muscalu et al., 2010), and on food conversion of cultured S. glanis (particularly using meal pellets), e.g. Le silure glane possède de nombreuses petites dents. Son système auditif est très perfectionné, lui permettant d'entendre la moindre vibration. There is a risk that wels catfish may impact on native fauna for a number of reasons.

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). Activity peaks during the night, with nocturnal foraging motivated by hunger stimuli. size, growth rate, survival rate, and reproductive success. Larvae and juveniles are benthic feeders of invertebrate zooplankton such as Rotatoria, Copepoda and Cladocera. https://wcd.coe.int/com.instranet.InstraServlet?command=com.instranet.CmdBlobGet&InstranetImage=1338217&SecMode=1&DocId=1464096&Usage=2, FAO, 2012. Il s'alimente assez peu en dessous de 15 degrés, ce qui conditionne sa répartition. (Le silure glane n'est pas un monster.) 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. Aquaculture - a gateway for exotic species. Le silure peut atteindre 2,60 m pour un poids de 100 kg (Individu de 2,11 m pêché en Meuse).
