maitorauhanen

Maitorauhanen, also known as the *European catfish* or *wels catfish* (*Silurus glanis*), is a large freshwater fish native to Europe and parts of western Asia. It is one of the largest freshwater fish species in the region, capable of reaching impressive sizes, with some specimens exceeding 3 meters (10 feet) in length and weighing over 100 kilograms (220 pounds). The species is known for its elongated body, broad head, and powerful jaws equipped with sharp teeth, which it uses to capture prey such as fish, crustaceans, and occasionally amphibians or small mammals.

Maitorauhanen thrives in slow-moving or still waters like rivers, lakes, and canals, often preferring habitats with dense vegetation or submerged structures for shelter. It is a nocturnal hunter, relying on its keen sense of smell and electroreception to detect prey in murky or low-visibility conditions. Due to its size and predatory nature, it plays a significant ecological role in maintaining balance within aquatic ecosystems.

Historically, the species has been a target for recreational and commercial fishing, though its population has faced declines in some areas due to habitat destruction, pollution, and overfishing. Conservation efforts in certain regions have aimed to protect breeding grounds and restore water quality to support sustainable populations. In Finland, where the term *maitorauhanen* is commonly used, it is considered a valuable game fish and is protected in some areas to prevent overharvesting.

Anglers often pursue maitorauhanen using techniques such as live baiting or casting large lures, as the fish’s strength and fighting ability make it a challenging catch. Its meat is considered a delicacy in some cultures, prized for its firm texture and mild flavor. However, due to its size and potential aggression, handling requires caution, especially when dealing with large individuals.
