There, populations appear to have remained relatively stable for decades, with little evidence of excessive predation on other native fish. Other anglers, hoping for the opportunity to catch such a huge fish, did the same in rivers in other countries, and the species proliferated. The method by which that fish was caught is unclear.

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. trap and kill salmon migrating through a hydropower plant. The smaller sized wels catfish will eat annelid worms, gastropods, insects and small crustaceans. In their native ran… Small channels consume invertebrates, but larger ones may eat fish. Though they’re often eaten in Eastern Europe, they’ve never really caught on as a seafood in other parts of the continent.

A study published by researchers at the University of Toulouse, France in 2012, documented individuals of this species in an introduced environment lunging out of the water to feed on pigeonson land. In its native habitat, where the animal is both fished and farmed for food, the wels catfish is not considered a problem species. Bigger specimens of European catfish have been noticed to additionally eat frogs, mice, rats, aquatic birds resembling geese, and maybe cannibalistic. Individuals larger than eight inches eat fish and large invertebrates. 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. Different Catfish species have varied feeding habits. After approximately one year, the fish becomes herbivorous, feeding on filamentous algae, probably ingesting larvae and periphyton accidentally. 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. 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. The diet of the wels catfish mainly includes worms, smaller fish and insects although some of the larger examples may also feed on mammals such as rats and mice. They’ve also adopted new hunting strategies not observed in their native range, such as snatching pigeons from land. 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. 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.

Larger specimens have been observed to also eat frogs, mice, rats, aquatic birds such as ducks and can be cannibalistic. “My concern is for these migrating species that have already decreased before the catfish came here,” says Santoul. Freshwater ecosystems as a whole are the most threatened in the world, with introductions of non-native species recognised as a leading cause, Hogan says. There are various reports of wels catfish … Larger individuals will eat frogs, mice, rats, and aquatic birds. 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 also have “an amazing ability to adapt to novel food sources,” says Santoul, who has documented how the catfish prey on Asian clams, another invasive 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.
