Is European catfish a threat to eels in southern France? Thème : Le silure glane . ©Dieter Florian/via wikipedia - CC BY-SA 3.0 DE. Most research on the environmental requirements of S. glanis has been focussed on introduced ranges in western Europe rather than northern habitats, as warmer water temperatures cause more serious ecological impacts, for example rapid growth (Boulêtreau et al. Eaux Libres, 38:19-21. Within these habitats the fish prefer benthic woody tree root habitats and stony crevices for refuge and cover. Status Review Report of 5 Species of Foreign Sturgeon.

Their eyes are small and they rely on their barbels and olfactory cavities to sense their prey and environment rather than vision. 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. Ecological Applications, 16(6):2313-2324. http://www.esajournals.org/perlserv/?request=get-abstract&doi=10.1890%2F1051-0761%282006%29016%5B2313%3AHDAIRO%5D2.0.CO%3B2, Copp GH, Britton JR, Cucherousset J, García-Berthou E, Kirk R, Peeler E, Stakenas S, 2009. 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. 2009).

Il fraye en couple puis la femelle pond une grande quantité d'œufs dans un nid qu'elle a préparé et sur lequel le mâle veille jalousement. 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. Another reason for introductions is as a biocontrol agent for controlling cyprinid fish. Preferred habitats are slow flowing lowland rivers, backwaters, shallow channels in floodplains and weed covered lakes. S. glanis has a broad omnivorous diet, including invertebrates and vertebrates such as small rodents. 2001) with some limited but renewed awareness among fish farmers in France and Germany (Linhart et al.

In the UK, the government has developed an environmental risk strategy including risk identification, risk assessment, risk management and risk review and reporting. Le silure glane (Silurus glanis) est une espèce de poissons d'eau douce du genre Silurus, originaire du Paléarctique occidental. 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. 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. Le silure glane. 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). Aquaculture in the Third Millennium. (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). In adults, the gonads are 9-15% of total body weight. 2013, http://www.fao.org/figis/servlet/static?dom=collection&xml=dias.xml, Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.

Males mature earlier than females, with mass maturation at 3-4 yrs, 57-66 cm and 1.3-2.3 kg, in contrast to females that mature at 4 yrs at minimum length 87.05 cm (Alp et al., 2004; Froese and Pauly, 2012). 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. Migration to European rivers including the Danube, Dnieper and Volga was via the Caspian, Black and Aral seas. Upstream spring migration in April for spawning requires temperatures of 8-10ºC and initiation of spawning occurs at 18-22ºC. Copepoda are the most frequent food of smaller larvae. The distribution in this summary table is based on all the information available. Le silure glane est un poisson géant qui fait régner la terreur dans les rivières.

Ann Rees, Environment Agency, Rivers House, Shaftsbury Rd, Sunrise Business Est, Blandford, Dorset DT118ST, UK. This species is in the lower region of the high risk score category of potential pests in ENSAR (European non-native species aquaculture risk assessment) to evaluate the risk of introduction, establishment, dispersal and impacts, although this may be variable according to context (Copp et al., 2009). Pesticides should always be used in a lawful manner, consistent with the product's label. Proceedings of the National Academy of Sciences of Belarus., Agrarian Science Series: 2:75-86. Wels catfish can be distinguished from other European catfish by the 6 long barbels under the lower jaw, the scaleless mucous-coated elongated body and the very small dorsal fin (Britton et al., 2010). Harka, A, 1984. Fisheries Management and Ecology, 14:263-268, Britton, J. R., Davies, G. D., Brazier, M., 2010. 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.

(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. Aquacultura Hungarica, 4: 135-144. 2011; Syväranta et al. 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. Following spawning, S. glanis exhibits a guarders and nesters reproductive strategy with the male protecting the cluster of eggs laid by the female in his nest excavated amongst the substratum and made from plant material. 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).

However the species still accounts for only a small percentage of European freshwater aquaculture. Results of rearing two-year-old European wels (Silurus glanis L.) in ponds stocked with intensively cultured yearling. Ulikowski, D., Borkowska, I., Chybowski, L., 1998. Néanmoins, un courant plus soutenu ne le The eggs are large, about 1-3 mm in diameter (Copp et al., 2009). Larval and juvenile stages of introduced fish are most susceptible to predation due to small size (Gozlan et al. Sperm cryopreservation of two European predator fish species, the Pikeperch (Sander lucioperca) and the Wels Catfish (Silurus glanis). The Import of Live Fish Act 1980 (ILFA) is a legislative framework to control importation of non-native fishes, and the Fish Invasive Screening Kit (FISK) is a scoring system to assess the range of risk of non-native fish introduction ranging from potential pest to harmless, based on the evaluation of life history traits of non-native fish species, e.g. Larval development and growth of the European wels (Silurus glanis) under experimental conditions fed natural and pelleted diets. 2008). 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. Perfectionniste psychologie. Aquatic Invasions, 2:113-116, Copp GH, Vilizzi L, Gozlan RE, 2010. (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. 129.

Weight and linear growth of wels (Silurus glanis L.) up to one month of age in aquarium rearing. 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). Espèces ressemblantes . Maximum reported age is 80 yrs (Kottelat and Freyhof, 2007), although life span is commonly 15-30 yrs. Maximum length is 500 cm (male), but common lengths are 300 cm, and weight 306 kg. It was introduced for angling and aquaculture in Spain, Italy and France. Consent is usually not granted for open waters, although enclosed waters are permitted (Britton and Pegg, 2007; Copp et al., 2009). Copp et al. Acta Ichthyologica et Piscatoria, 27(1), 41-50.

Age and growth of the European catfish (Silurus glanis) in a Turkish Reservoir and comparison with introduced populations. 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. 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.

Sexual maturity is generally 3-4 yrs, between 39-71 cm length. 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. Reproduction is controlled by environmental cues, e.g. S. glanis cultivation has played a minor role in cyprinid pond farming. In parts of its native range (e.g. L’introduction récente et sans aucune autorisation, faut-il le rappeler, du silure glane dans l’ensemble du réseau hydrographique pour satisfaire une poignée de pêcheurs, amateurs du « catch and release », n’a donné lieu à aucune sanction, alors que ce grand prédateur n’est pas inactif dans les cours d’eau.
