Wels catfish (Silurus glanis)

Type of waters inhabited: Freshwater

The wels catfish is the largest predator of European freshwater and has found an ideal habitat in the rivers, lakes, and canals of Italy. Introduced to Italy a few decades ago, the wels catfish has successfully acclimatized to slow-flowing environments, such as the Po River, where it quickly gained notoriety among sport fishermen. This fish, belonging to the family of ictalurids and commonly known as catfish, is a nocturnal predator with crepuscular habits, known for its voracity and adaptability.

Habitat

The wels catfish lives in a variety of aquatic environments, preferring calm and deep waters. The ideal places to find it include:

  • Rivers: such as the Po and its tributaries, where the currents are slow.
  • Lakes: large lakes with muddy bottoms, rich in aquatic vegetation.
  • Canals: artificial canals and backwaters that offer natural shelters.

This fish often hides among branches and roots in the muddy bottom during the day, emerging to hunt for food at dusk. Its diet is very varied and includes fish of different species, rodents, amphibians, reptiles, and even aquatic birds. Thanks to its wide mouth and sensitive barbels, the wels catfish can detect prey even in turbid waters.

Fishing Techniques

The techniques for targeting the wels catfish are numerous and constantly evolving. Here are some of the most effective:

  • Live bait fishing: Using live fish as bait can be very effective. This technique can be practiced with bottom or float rigs, allowing the bait to move naturally in the water.
  • Bottom fishing: This technique involves using baits placed on the bottom of the watercourse. It is particularly useful during nighttime when the wels catfish is active.
  • Spinning: By using large lures such as jerkbaits or spinners, anglers can attract the attention of the wels catfish from both shore and boat. This technique is especially effective during twilight hours.
  • Trolling: Trolling with live or dead bait can yield good results. This technique allows for covering large areas of water in search of the wels catfish.
  • Fly fishing: Although less common, using streamers can be effective in calm or turbid waters.

The wels catfish loves to linger near natural or artificial obstacles such as bridges and weirs. It is important to use robust equipment to counteract the strength of this fish during combat.

Challenges and Adventures

Fishing for wels catfish offers unique thrills for sport fishermen. Knowing its habitat and feeding habits can make the difference between a successful fishing day and a disappointing one. The wels catfish is primarily active during nighttime hours, making evening outings particularly interesting. During colder periods of the year, it may also move during the day.

Catching a wels catfish not only represents an exciting challenge but also provides unforgettable moments for every fishing enthusiast. With the right techniques and strategies, every outing can turn into an exciting adventure in Italy's beautiful aquatic environments.
