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. 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 all catfishes, wels have highly developed senses, particularly in detecting prey vibrations. In France’s Garonne River, the catfish will sometimes wait inside a fish tunnel to trap and kill salmon migrating through a hydropower plant.

Major foods are aquatic insects, crayfish, mollusks, crustaceans and fishes. Individuals larger than eight inches eat fish and large invertebrates. 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. 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. Juveniles are benthic feeders, preying on a variety of fish and invertebrates. Like most freshwater bottom feeders, the wels catfish lives on annelid worms, gastropods, insects, crustaceans, and fish. Larger specimens have been observed to also eat frogs, mice, rats, aquatic birds such as ducks and can be cannibalistic. 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. This along with its long play time makes this build fairly suitable for acquiring Wisdom. More often than not, however, large freshwater fish are declining, threatened by invasive species, habitat loss, and overfishing. Sixteen fish were stocked into each of 12 experimental tanks being part of a freshwater recirculation system. One way to fight invasive species? These species, often called megafishes, have declined globally by a staggering 94 percent since 1970, according to a 2019 study. 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.
