Are you so into the mild flavor of catfish? Welcome to our catfish fan club! We are here to share our experience in enjoying this tasty cuisine.
However, catfish will spoil over time, especially when not kept in optimal storage conditions like other fish. So how to tell if catfish is bad, and how can you store it properly?
Don’t worry! We will help you explore the signs of a spoiled catfish. You can also learn some pro tips to extend its lifespan and maintain its quality.
Now, let’s jump into the details!
How to Tell If Catfish Is Bad
There are five signs to help you tell if your catfish is bad: sell-by date, smell, color, texture, and taste. You should perform the test in that order.
Sell-by Date
If you buy catfish from the supermarket, check the sell-by date. It indicates the last day by which the market should sell the fish.
However, the label can only tell you are buying a fresh product. In some cases, some fish go bad before reaching that date. Meanwhile, some are still safe to eat even if they have passed their sell-by date, under specific storage conditions.
Smell
The unpleasant odor is one of the most obvious signs that your catfish has gone bad. While these fish have a mild, ocean-like aroma when fresh, they turn sour once spoiled. In the worst condition, they smell like rotting eggs or ammonia.
Color
Fresh catfish are silver or white on the undersides and turn grayish-blue or black on the back. You will also notice a slight sheen on their skin.
However, the color turns dull gray or brown when they go bad. There can be discolored patches.
Texture
A fresh catfish is firm to the tough with hard scales. If it spoils, the texture will become slimy and mushy. As the decomposition process continues, slime buildup can make the fish slippery.
Besides, the skin of a spoiled catfish is soft and comes loose from the scales and flesh. You can test by depressing its skin with your finger. The lack of elasticity prevents it from returning to its original shape.
Taste
If you are not sure whether your catfish has gone bad, perform the final test: tasting it. Catfish have a mildly sweet flavor with a moist texture. It’s often less flaky than other types of white fish.
On the other hand, the spoiled catfish tastes sour. Believe us; you can immediately feel how terrible it is at the first bite.

Eating spoiled catfish is dangerousHow Long Can Catfish Last?
It depends on where you keep the fish. You have three options as follows:
- At room temperature: 2 hours.
- In the fridge: 2 days.
- In the freezer: 5 to 6 months.
The different lifespan of catfish, when kept in different places, helps you choose the ideal method to store them.
At Room Temperature
If you intend to cook catfish right after buying or catching them, leave them on the countertop for no more than two hours.
Do not keep catfish there for too long because they will spoil quickly. When exposed to air, bacteria can grow rapidly on the surface and inside the fish.
In the Fridge
Fresh catfish can last in the fridge for two days. However, whether your fish can remain good after that time depends on how you refrigerate them. Here are some tips that help:
- Wash the catfish carefully to remove any dirt and debris from the surface.
- Remember to pat the fish with a paper towel before storing them.
- Wrap the fish in aluminum foil or plastic wrap, so air can’t get inside.
- Put the fish in the coldest part of your fridge and away from other foods to avoid cross-contamination.
In the Freezer
Freezing helps your catfish the longest. If you intend to store them for months, consider freezing them. But try to do it correctly, or all you have after months of freezing is the spoiled fish.
Here are some important things to bear in mind when freezing catfish:
- Wash and pat the fish to dry as you do when refrigerating them.
- You can wrap the catfish in their original packing in aluminum foil. Alternatively, put them in a freezer ziplock bag with some water inside. Don’t forget to squeeze all the air in the bag before putting it in the freezer.
- Label the bag with the date and freeze it at 0°F or below.
The lifespan of catfish depends on how you store themOther Ways to Keep Catfish for Longer
Refrigerating and freezing are the two most popular storage methods. However, you can also consider canning and curing catfish to preserve their quality.
Canning
Canning catfish involves cooking them in a sealed container under high pressure. This method will destroy bacteria, keeping the fish in good condition for years.
Often, commercially canned catfish can last for five years. Meanwhile, home canning is good for only one year.
However, you must follow the correct canning techniques. It’s about using the right pressure canner, temperature, and pressure to process the catfish.
Curing
Curing can be salting or smoking. If you smoke fresh fish and vacuum pack them, they can last about three weeks. And if you freeze them after smoking, they can remain edible for three months.
Salting is also an excellent cooking method. Once salted with salt, sugar, and spices, catfish can last three to five days in the fridge.
