Catfish

Catfish: Nutrition, History and Cooking Guide

Catfish is a broad term for fish of the order Siluriformes, encompassing thousands of species across the world's freshwater systems. The channel catfish (Ictalurus punctatus) and blue catfish (I. furcatus) dominate the North American farmed and wild fishery; the Mekong giant catfish (Pangasianodon gigas) is the largest freshwater fish in the world; and the Pangasius (iridescent shark catfish) from Southeast Asia is one of the most widely farmed fish globally, sold in Europe as pangasius or basa. In the American Deep South, catfish has deep cultural roots: fried catfish with hush puppies and coleslaw is one of the defining dishes of Southern American cuisine, and Friday night catfish fries are a beloved community and church tradition across the Mississippi Delta and surrounding regions. In West Africa and across tropical Asia, various catfish species are central to everyday cooking — smoked, dried, and used fresh in soups and stews.

Nutritional Value of Catfish

Catfish provides 95 kcal and 16.4 g of protein per 100 g, with 2.8 g of fat — lean and high in protein. It provides complete protein, B12, niacin, selenium, phosphorus, and vitamin D in meaningful quantities. It contains omega-3 fatty acids, though at lower levels than marine oily fish.

Health Benefits of Catfish

Catfish is a lean, nutritious freshwater fish with good protein content and useful vitamins and minerals. Its vitamin D content is nutritionally significant. B12 supports neurological health. As a farmed fish, catfish can be very sustainable depending on production method — responsibly farmed catfish from closed pond systems has a relatively low environmental impact. Choose certified farmed catfish or wild-caught channel catfish for the best combination of quality and sustainability.

How to Select and Store Catfish

Catfish fillets should be white to cream, firm, and smell clean without muddiness. Pangasius/basa fillets are widely available frozen in British supermarkets. Refrigerate for up to two days; freeze for up to three months.

How to Cook Catfish

Catfish suits pan-frying, deep-frying, baking, and grilling. For Southern fried catfish: dredge fillets in seasoned cornmeal (or flour) and deep-fry at 180°C for four to five minutes until golden and cooked through. For baked catfish: coat with a spicy crust (paprika, cayenne, garlic powder, black pepper) and bake at 200°C for fifteen minutes. Catfish holds up well to assertive Cajun and Creole seasoning. Basa/pangasius suits the same preparations and is particularly good in curries and Southeast Asian-style preparations with coconut milk and lemongrass.
