How Long Does Catfish (Raw) Last?

Fresh catfish fillets should have a mild, slightly sweet smell rather than a strong fishy one, and the flesh should look moist and firm rather than dull or mushy — as a lean fish, catfish doesn't develop the oily rancidity a fattier fish like salmon might, so an ammonia-like or sour smell is the clearer warning sign here.

A slimy texture on the fillet's surface, beyond its normal slight moisture, and flesh that leaves an indentation when pressed rather than springing back are the signs it's spoiled. Because so much catfish reaching US markets comes from an established domestic fish-farming industry, fillets tend to be fairly consistent in size and quality at purchase, which makes an unusual smell or texture at any point during its short 1-2 day fridge window a more reliable red flag than it might be for a more variable wild-caught fish.

Catfish fillets that have a pinkish tinge rather than the expected white-to-off-white color are worth a closer look before cooking, since that coloring can sometimes indicate the fish hasn't been properly bled or processed, a quality issue distinct from the more common freshness checks like smell and texture.

Catfish nuggets, smaller cut pieces sometimes sold specifically for frying, decline slightly faster than a whole fillet given their greater surface-area-to-volume ratio, similar to how any smaller cut of protein tends to spoil a bit faster than a larger, intact piece.
