Information regarding the wels catfish nuclear and mitochondrial genomes is sparse. Proceedings of the National Academy of Sciences of Belarus., Agrarian Science Series: 2:75-86. Secondly, catfish are opportunistic foragers, able to switch their feeding to the most suitable resource available. It took Ferrari 40 minutes to catch the Wels catfish and he decided to release the fish back into the water so he could be caught again in the future. Use of frozen zooplankton in the intense rearing of European catfish (Silurus glanis L.) larvae. Dokuchaeva, S. I., 2011. In 2005, a behemoth Mekong giant catfish, weighing in at a scale-tipping 646 pounds (293 kilograms) was caught in a remote village in Thailand near the Mekong River. Some example maps demonstrate the extent of introductions. 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. Article from factzoo.com. Contribution of anadromous fish to the diet of European catfish in a large river system. http://www.fao.org/fishery/en. Wels catfish are distinguishable by an elongated scale-less, slime-covered body, with strong upper body strength and laterally flattened tail. Migration to European rivers including the Danube, Dnieper and Volga was via the Caspian, Black and Aral seas. 2003; Carol et al. They can be identified by 6 barbels, 2 long ones on each side of the mouth and 4 shorter ones from the lower jaw. 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). > 10°C, Cold average temp. Results of rearing two-year-old European wels (Silurus glanis L.) in ponds stocked with intensively cultured yearling. 2010). Journal of Biological Research, 15:25-35. http://www.jbr.gr/papers20111/03-Vittas-et-al.pdf, Wisniewolski W, 1989. 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). However, there are reports of breeding in some lakes in southern England at present temperatures (Copp et al., 2009). 60:21-36. It took over an hour for the Thai fishermen to reel in the heavy catfish. S. glanis cultivation has played a minor role in cyprinid pond farming. monkeys, cats, dogs, birds, and other catfish have been found in their stomachs. Évolution de son aire de répartition et prédiction de son extension ([English title not available]). According to Naylor et al. Roczniki Nauk Rolniczych, Seria H, Rybactwo, 102(1):131-167. Journal of Applied Icthyology, 1:27-31, Jamróz, M., Kucharczyk, D., Kujawa, R., Mamcarz, A., 2008. 2007; Carol et al. The Wels catfish is a large fish native to wide areas of central, southern, and eastern Europe. It appears to establish relatively easily after introduction, especially in warmer climates such as around the Mediterranean (Crivelli, 1995). 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.

Sperm cryopreservation of two European predator fish species, the Pikeperch (Sander lucioperca) and the Wels Catfish (Silurus glanis). 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. Fischokologie, 6:7-20, Kottelat M, Freyhof J, 2007. Detailed coverage of invasive species threatening livelihoods and the environment worldwide. It was first introduced to England in 1880, into enclosed recreational lakes of a private Bedfordshire manor estate at Woburn Abbey, for fishing.

The diet of adult fish is known to include sunbleak (Leucaspius delineatus), ruffe (Gymnocephalus cernuus), roach (Rutilus rutilus), dace (Leuciscus leuciscus), common bream (Abramis brama), silver bream (Blicca bjoerkna), rudd (Scardinus erythrophthalmus), bitterling (Rhodeus sericeus), European eel (Anguilla anguilla), red swamp crayfish (Procambarus clarkii) and signal crayfish (Pacifastacus leniusculus). Froese R, Pauly D, 2012. Identification of non-native freshwater fishes established in Europe and assessment of their potential threats to the biological diversity. In fact, the Piraiba is the largest of the catfish species found in the Amazon. 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. 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. River Hampshire Avon assessment of risk posed by S. glanis. Archiwum Rybactwa Polskiego, 11: 295-300, Valadou B, 2007. In: Status Review Report of 5 Species of Foreign Sturgeon : National Marine Fisheries Service.78 pp. 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).

Fish and Fisheries, 10(3):252-282. http://www.blackwell-synergy.com/loi/faf, Copp GH, Garthwaite R, Gozlan RE, 2005. 2012). 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. 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). Gullu, K., Guner, Y., Koru, E., TenekecIoglu, E., Sayg, H., 2008. [English title not available]. The wels catfish S. glanis is part of the family Siluridae, a group of freshwater fish native to Europe, Asia and Africa. It can reportedly weigh up to 350 kg (770 … Since 1975, it has been farmed for its meat in pond cultures in Italy and former Yugoslavia, and also in its native range in Hungary, Poland, Slovakia and Lithuania (and also Belarus -- Dokuchayeva, 2011), where the species is considered an expensive meat delicacy. Sweden and Greece) it is under threat from climate and habitat changes and species introductions (Copp et al., 2009; Britton et al., 2010). Fisheries and Aquaculture Department. The current weight record for a wels catfish is over 300 pounds, but according to the Daily Mirror, Ferrari may have set a record for the largest catfish to be caught with a rod and reel. S. glanis is the largest-bodied European freshwater fish. [ISBN 90-71625-03-6], Hilge, V, 1984. But they have become the largest freshwater predators we have. The addition of wels catfish in recreational catch and release fisheries is likely to have a beneficial revenue effect. Copp et al. Fisheries for non-native species in England: angling or the environment? Paulie’s flathead catfish was frozen for many years before it was presented to the Kansas Department of Wildlife, Parks, and Tourism in 2016 for further examination. 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. Gozlan et al. Voracious invader or benign feline? The eggs are large, about 1-3 mm in diameter (Copp et al., 2009). 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. 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). Alp A, Kara C, Buyukcapar HM, 2004. Voracious invader or benign feline? The feeding selectivity of wels (Silurus glanis L.) in Lake Goreckie.

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). Since 1975, it has been farmed for its meat in pond cultures in Italy and former Yugoslavia, and also in its native range in Hungary, Poland, Slovakia and Lithuania (and also Belarus -- Dokuchayeva, 2011) where it is considered an expensive meat delicacy. Filipiak, J., Sadowski, J., Trzebiatowski, R., 1997.

Handbook of European Freshwater Fishes. UK: Environment Agency, 30 pp. It … It has been introduced but not established in Cyprus, Belgium and Algeria (Froese and Pauly, 2012). Following introduction outside its native range, the wels catfish has become established in Bosnia-Herzegovina, Spain, Denmark and Tunisia with some ecological effects. http://www.fishbase.org. Risk of establishment increases in warmer climates such as the Mediterranean as rapid growth and breeding are enhanced by warmer temperatures of 25-28ºC in contrast to likelihood of more sporadic establishment in Northern climates. 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. Aug 1, 2012 - Catfish - Many species and many shapes and sizes of these whiskered wanderers of the murky muddy waters live all around the world. Nearly all of these catfish are listed as the world record for their species in the International Game Fish Association’s (IGFA) World Records Database. Copp G H, Britton J R, Cucherousset J, García-Berthou E, Kirk R, Peeler E, Stakėnas S, 2009. FishBase. Movement to new areas is generally through introduction for aquaculture and recreational fishing, or sometimes for biological control. 1996; Ulikowski et al. Martino A, Syväranta J, Crivelli A, Cereghino R, Santoul F, 2011. 2008). Egg size is 3 mm and larvae length at hatching is 8.5 mm. S. glanis exhibits cannibalism when food resources are scarce, or (Copp et al., 2009) in angling waters when there is variation in size among members of the species. > 10°C, Cold average temp. ], Copp GH, Moffatt L, Wesley KJ, 2007. Studies on the growth of sheatfish (Silurus glanis L.) in river Tisza. Age at maturity is 3-4 yrs. Researchers determined that the record flathead catfish was at least 22 years old, grew very rapidly, and was most likely a male. 129. Ferrari's sponsor did say that his catch may hold the world record for a fish caught with a Torpedo spinning rod made by an Italian manufacturer. Development of technological regimes of European catfish (Silurus glanis L.) growing in the ponds of Belarus. River Ebro, Spain. For more information on the Invasive Species Act and Regulations visit www.ontario.ca/invasionON. Fisheries Management and Ecology, 11:203-212, Hilge V, 1989. 2010). Concerns about accidental unregulated spread (flooding enabling spread from angling waters to watercourses and rivers) and intentional unregulated releases (for angling) imply that S. glanis introductions need to be investigated, particularly as angling and dispersal are cited as the main introduction routes for introduced fish in the UK ( Copp et al. Females deposit eggs at 30,000 per kg of body weight. 2009). 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. Average temp. 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). The record for the largest flathead catfish belongs to Ken Paulie, who landed his big flathead over 20 years ago. Testing the Alms Welsfutter diet on sheath fish (Silurus glanis) culture in silos. 2003), and also overwintering mortality as S. glanis larvae are unable to survive low temperatures <13ºC (David, 2006; Copp et al.

Preliminary telemetry data on the patterns and habitat use of European catfish (Silurus glanis) in a reservoir of the River Ebro, Spain. About time it had it's picture taken, then. Currently found in Central and Eastern Europe, the wels catfish can grow to extraordinary sizes (over 9 feet) depending on the habitat it is located. 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. In parts of its native range (e.g. On average a wels catfish is 4-5 feet long, and weighs 40-50 lbs.

Invasiveness of non-native fish species may be related to frequent repetitive introductions through anthropogenic pathways. 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). 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. Linolenic acid supplementation in the diet of European catfish (Silurus glanis): effect on growth and fatty acid composition. 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. Copepoda are the most frequent food of smaller larvae. ‘Monster’ albino wels catfish may be largest ever caught. The U.K. Mirror reported that the catch is the world's largest wels catfish to be caught by rod and reel. 2009; Copp et al. Evaluation of selected feeds differing in dietary lipids levels in feeding juveniles of wels catfish, Silurus glanis L. Acta Ichthyologica et Piscatoria, 38(2), 91-96. doi: 10.3750/AIP2008.38.2.02, Muscalu, R., Muscalu, C., Nagy, M., Bura, M., Szelei, Z. T., 2010. 2010), and spawning behaviour was also temperature sensitive -- spawning was delayed for months until water temperatures were within the 18-23ºC range (Wiśniewolski, 1989; Copp et al. S. glanis is a popular fish among anglers because of its large size and relatively frequent capture. Upstream spring migration in April for spawning requires temperatures of 8-10ºC and initiation of spawning occurs at 18-22ºC. Mekong Giant Catfish. (2002), S. glanis has been farmed historically in Austria, Bulgaria, Croatia, Germany, France, Hungary, Greece, Macedonia, Poland, the Czech Republic and Romania. Journal of Applied Ichthyology, 23:654-660, Carol J, Zamora L, García-Berthou E, 2007. (2009) present a table of at least 55 fish species found in the natural diet of S. glanis. Currently, wels catfish are predominantly found in the South East and Midlands areas of the UK.

Native to eastern Europe and western Asia it is now established in several countries to the west and south of its native range. Foraging is an important aspect of growth and Muscalu et al. The record for the largest Goonch ever caught belongs to Jakub Vágner, the host of National Geographic's “Fish Warrior.” Vágner's Goonch was 165 pounds 5 ounces (75 kilograms) and over 5 feet (1.57 meters) long. The wels catfish, the largest freshwater fish found in Europe, measured 8 feet, 8 inches and, based on a measurement formula, weighed an estimated 286 pounds. … Science (Washington), 294(5547):1655-1656, Paschos, I., Nathanailides, C., Perdikaris, C., Tsoumani, M., 2004. For positive economic effects, see the sections on Uses (Invasive Species Compendium) or Production, Economic and Socioeconomic Aspects (Aquaculture Compendium). Public Domain - Released by Yuriy75/via wikipedia - CC0. In 2015, an Italian fisherman named Dino Ferrari was featured in international news for capturing a monster Wels catfish in the Po Delta. 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. (2010) revealed that water temperatures <17ºC marked a cessation in foraging activity and growth, which indicates thermal ecological sensitivity of S. glanis of particular relevance in northern habitats. PLoS ONE, 7(12), e50840. [Unpublished report], Ricciardi A, Steiner WWM, Mack RN, Simberloff D, 2000. More information about modern web browsers can be found at http://browsehappy.com/. There is considerable research on growth of S. glanis in aquaculture (Harka, 1984; Hilge, 1984, 1985; Mareš et al. A review of the environmental biology of European catfish Silurus glanis in its native and introduced ranges. Silurus glanis (wels catfish); adult, in the open water of a former surface mine near Leipzig, Germany. 2002; Varadi et al. Goonch catfish have reportedly been known to eat corpses from funeral pyres on the Kali River, which runs between Nepal and India. It is also established in Italy, Syria, Portugal, Croatia, Turkey, the UK, France, the Netherlands and China, although ecological impact here is unknown. http://www.fishbase.org, Gozlan RE, Flower CJ, Pinder AC, 2003. S. glanis is a robust species regarding transference outside its native range, and exhibits tolerance to low oxygen levels in water. Maximum reported age is 80 yrs (Kottelat and Freyhof, 2007), although life span is commonly 15-30 yrs. 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). Assessing the effects of climate change on aquatic invasive species. It is the largest-bodied European freshwater fish (Copp et al., 2009). Length at first maturity is 39-71 cm. The sexual cycles of the catfish S. glanis, pike E. lucius, perch P. fluviatilis and pike-perch L. lucioperca. Wels catfish are carriers of viral pathogens, namely spring viraemia of carp (SVC) and European sheatfish virus (ESV), which may adversely impact native fish including salmonids and amphibians. Oxford, UK: Fishing News Books, 46-57, Slavík O, Horký P, Bartoš L, Kolárová J, Randák T, 2007. Jorge Masullo de Aguiar currently holds the world record for the largest Lau-Lau (Piraiba), which is a species of catfish that is native to South America. The distribution in this summary table is based on all the information available. The wels catfish's mouth contains lines of numerous small teeth, two long barbels on the upper jaw and four shorter barbels on the lower jaw. The average size of the species is about 1.2–1.6 m (3.9–5.2 ft), and fish more than 2 metres (6.6 ft) are very rare.
