Physical Characteristics of Wels Catfish

Wels Catfish are easily recognizable by their long, cylindrical body, flat head, and broad mouth filled with needle-like teeth. They have no scales but are covered in slimy skin. Their coloration can vary from grayish-brown to green or even black, and sometimes they have small spots or blotches on their skin.

Habitat of Wels Catfish

Wels Catfish are found in large rivers and lakes throughout Europe. They prefer slow-moving water with deep holes or bends where they can hide and ambush prey. They are very territorial and will often defend their area against other Wels Catfish.

They are opportunistic predators and will eat just about anything they can catch, including fish, frogs, birds, rodents, and even smaller Wels Catfish. They are most active at night and spend most of their time near the bottom of the water column.

Conservation Status of Wels Catfish

Wels Catfish are not currently listed as endangered, but their populations have been impacted by overfishing and habitat degradation. They are often caught as bycatch in commercial fisheries or targeted by anglers for sport. They are also vulnerable to pollution and changes in water temperature and flow.

Efforts are being made to protect and restore Wels Catfish populations through conservation programs, habitat restoration, and management of fishing pressure. Anglers are encouraged to practice catch and release and to handle Wels Catfish carefully to prevent harm to the fish.
