Its body is elongated and often reaches remarkable lengths. Prey is detected by both smell and vibration. Major foods are aquatic insects, crayfish, mollusks, crustaceans and fishes. Wels catfish encircle a small island in the Tarn River, preparing to grab unsuspecting pigeons. On a small island below, in the Tarn River, pigeons wandered about, oblivious to the group of wels catfish moving near the gravel bank. The diet of a mature catfish, especially one of the larger species of the fish, tends to become more species specific as it grows and ages. An analysis of more than 250 catfish stomach contents revealed shad made up more than 80 percent of their diet—“the giants’ feast,” according to the study. Like all catfishes, wels have highly developed senses, particularly in detecting prey vibrations. Individuals larger than eight inches eat fish and large invertebrates. In the same river, wels catfish have also learned to target spawning Allis shad at the river’s surface at nighttime, when the fish are preoccupied in their courtship displays, according to a study published in November 2020. Different Catfish species have varied feeding habits. As its name suggests, this catfish has a flat head. But their hunting skills may give them their most formidable edge. More often than not, however, large freshwater fish are declining, threatened by invasive species, habitat loss, and overfishing. In France’s Garonne River, the catfish will sometimes wait inside a fish tunnel to trap and kill salmon migrating through a hydropower plant. Native Range: Central and Eastern Europe. In 1974, a German angler released several thousand wels fry into Spain’s Ebro River. Suddenly a fish catapulted out of the water and onto land, snatching a pigeon in a flurry of feathers before heaving itself back into the river, bird in mouth. There are also no efforts underway to eradicate the catfish, Santoul says. Their skin is also edible, but it must be removed before cooking. The first time Frédéric Santoul witnessed the voracious feeding habits of Europe’s largest freshwater fish, he was standing on a medieval bridge in Albi, a town in southern France. He’s concerned the predator could wipe out many native Western European fish species, fundamentally altering river ecosystems that are already struggling from the impacts of dams, water pollution, and overfishing. The species, which can grow up to 10 feet long and weigh up to 600 pounds, is native to Eastern Europe, but has since expanded into at least 10 countries throughout Western and Southern Europe. A catfish hunts mainly at night and is not a picky eater, with invertebrates, fish, frogs, rodents and birds in its regular diet. Ecological shifts driven by climate change, including warming temperatures and changes in precipitation patterns, could create even more favourable conditions for the wels catfish to spread, scientists say. Distribution. Blue catfish commonly attain weights of 20 to 40 pounds, and may reach weights well in excess of 100 pounds. The wels catfish is a freshwater fish, also known as sheatfish. But, he adds, there’s one species the catfish does not harm: Us. Wels catfish, which are native to Eastern Europe, can grow up to 10 feet long.

This species is a nest guarder which gives it an advantage over other native fish that do not nest guard young. “If we at the European level we do not coordinate our conservation plans, it might be too late to save them.”. Local Concern: Voracious predatory habits make the wels catfish a serious threat to populations of native vertebrates. A Catfish’s natural diet consists mainly of fish, but is a predator with a considerable appetite and varied palate and will consume amphibians, worms, crayfish, leeches, small swimming mammals like mice, rats or voles, and water birds from chicks to adult ducks. There, populations appear to have remained relatively stable for decades, with little evidence of excessive predation on other native fish. European catfish Diet.

Wels Catfish is defined for a long time, without body scales; A large flat head; And a wide mouth with rows of small teeth like sandpaper – hundreds of them. “Climate change affects species differently, with some alien species potentially having much larger distribution gains compared to natives,” says Rob Britton, a fish ecologist specialising in invasive species at Bournemouth University, in the U.K. Wels catfish Classification. Larger individuals will eat frogs, mice, rats, and aquatic birds. The fry are said to feed on insect larvae, tadpoles, tubifex worms and other invertebrates, before moving on to larger food items such as fish, mussels, crayfish, leeches, worms and even small birds and mammals. Like many invasive species, wels catfish thrive in rivers that have been altered by humans, where high water temperatures and low oxygen levels may have pushed out native species. They’ve also adopted new hunting strategies not observed in their native range, such as snatching pigeons from land. Like most freshwater backside feeders, the wels catfish live on annelid worms, gastropods, bugs, crustaceans, and fish. This stingray could be world's biggest freshwater fish, rivers there stay warmer for longer periods of the year.

The Channel Catfish (Ictalurus punctatus) and Blue Catfish (Ictalurus furcatus) feed mainly at night using taste buds in the sensitive barbells and throughout the skin to locate prey. There is evidence that the wels catfish, which need water temperatures of at least 68 degrees Fahrenheit for their annual spawning, are colonising previously uninhabited rivers in Belgium and the Netherlands as those water bodies warm, Santoul says. A primarily nocturnal, opportunistic carnivore preying mostly on other fishes and crustaceans in nature with amphibians, insects, birds (usually young waterfowl) and, exceptionally, small mammals also taken. It uses its large mouth to swallow prey whole. Take the Flathead catfish as an example.

There are also signs that catfish spawning now occurs several times a year in France, as rivers there stay warmer for longer periods of the year, he says. But in newly inhabited rivers, these aquatic invaders are targeting endangered and commercially important migratory fish, such as Allis shad and Atlantic salmon, whose European populations are already in serious decline, Santoul says. (See the stingray that may be the world’s biggest freshwater fish.). There are other examples of large, invasive fish disrupting freshwater ecosystems: the Nile perch, whose introduction as a game fish into Lake Victoria and other East African lakes in the 1960s resulted in the collapse of at least 200 native cichlid fish species by the 1980s.

Wels catfish, which are native to Eastern Europe, can grow up to 10 feet long. Despite a reputation as a gaping, broad-headed beast that attacks and even kills humans, “they’re harmless and curious with people, and you can swim right up to them in the river,” Santoul says. “The cumulative effects of these factors could lead to a collapse of fish populations in another 10 years,” warns Santoul.
