Costco's fresh farmed whole catfish is sold by the pound and sourced from domestic aquaculture farms. Whole catfish are presented with the skin on and head intact, making them ideal for traditional preparations such as frying, grilling, baking, or stewing. Farm-raised catfish has a mild, slightly sweet flavor with a firm, white flesh that holds up well to a variety of cooking methods.

Catfish is a lean source of protein and a good source of omega-3 fatty acids, vitamin B12, and selenium. It is lower in mercury compared to many other fish varieties, making it a suitable choice for regular consumption. Whole catfish can be scored and seasoned before cooking, or filleted at home for a boneless preparation.
