The catfish (Silurus glanis) is the largest freshwater fish within the UK and probably also within Europe. Read more about this large and powerful fish.

The Northern location, cooler temperatures and availability of food inhibits the size these giants can grow within the UK. In Europe these warm water fish with plenty of food can reach weights of up to 674lb!

"Catfish are predatory but also scavengers and will eat most baits as well as most small animals and birds." Carl Nicholls, fisheries & angling manager

Appearance: catfish are easily identified with long slender bodies, broad heads, wide mouths and long slender barbels. The Wels catfish has two long barbels on the upper jaw and four shorter barbels on the lower jaw. These barbels are used to hunt and detect prey. The body is dark brown to black in colour with a soft yellow to white belly. The anal fin is long (usually the half the length of the body) and finishes right at the base of the tail fin.

British record: 62lb (British Record Fish Committee January 2015) 100lb+ fish have been recorded but not accepted due to being illegally introduced to the water.

Lateral Line scale count: 33-40 (this is the dark row of scales along the central length of the fishes body).

Lifespan: up to 90 years

How to catch a catfish

Catfish can be large and are very powerful fish. Strong tackle is essential. They prefer to hunt in murky waters and primarily feed during the night. They use their long highly sensitive barbels to sense their surroundings and search out resting fish and other food sources. Smelly dead baits and fishing tactics similar to those used for large pike or zander are very successful. In recent years, the use of large pellets have been used to great effect and seem to be the preferred method now. Use a hook larger than a size 2 and fish a couple of large 25+mm hair rigged pellets.

Where to catch a catfish

Marsworth Reservoir, near Tring has a small population of catfish which were introduced legally by the Rothschild family who controlled the sporting rights on the Tring Reservoir complex for many years.
