Catfish is a fish eaten for its flesh; the figures here describe it raw. It mainly provides protein, with some fat, as well as vitamins and minerals. Per 100g, raw catfish contains 18g of protein, 2.8g of fat, 0.4g of saturated fat and 90µg of iodine.

Protein supports the growth and repair of body tissues, while iodine is needed to make thyroid hormones, which help regulate metabolism. The saturated fat and salt values may be relevant to people monitoring their intake. Cooking changes the water content of fish, and added oil, salt or sauces will affect the nutritional content of the finished dish. Full nutrient figures are provided in the tables below.
