While the fresh catfish will catch your eyes with their bright white or pinkish color, freshwater smell, and shiny skin, the bad catfish should also catch your attention (in a bad way) as its signs are noticeable like the sour smell, dull color, and sticky texture.

In general, buying catfish from a place where there are many people purchasing fish daily such as the fish market, reduces the chances of ending up with bad fish, but it never eliminates it.

When you are looking for a good catfish, you should not only rely on the fish smell, as long as the fish is tender with a bright shiny skin it will be good to cook because sometimes the smell of the fish doesn’t seem good for you, at the end they are a raw fish which will always smell bad for some people.

How long do catfish stay good in the fridge? 

Fresh catfish do stay good in the fridge for up to two days, according to the food and drug administration. While some anglers say that a fresh catch of catfish can stay up to three days in the fridge, it is always better to stay on the safe side.

Usually, raw catfish can stay good in the fridge for one to two days, and cooked ones can stay good for three to four days.

If you are planning to cook raw fish after more than 2 days, the freezer is your best option to store the fish for five to six months and you can thaw it whenever you want to cook. 

Note if you use the microwave or cold water to defrost the catfish you need to cook it immediately because it will go bad if you stored it in the fridge or the freezer again.

If you are planning on catching the catfish yourself, make sure you know how to properly kill the catfish after catching it as they have a tendency to stay alive for longer than you think (and they make the weirdest sounds).

How long does it take for catfish to go bad?

A catfish can go bad after two hours if you left it at room temperature, especially because fish skin can grow bacteria quickly in the 40 degrees to 140 degrees temperature range.

Note that the fatty fish have a higher chance of getting spoiled, and they do so more quickly, so if you are going to buy a piece of a catfish make sure to check the sell-by date because sometimes it expires during their storage time, especially with catfish’ short shelf life. 

How to make your catfish last longer?

As we mentioned before the methods to store your catfish, you will notice that the best way to make your catfish last longer is to store it in the freezer, which makes the catfish last for more than 5 months, whether the fish is raw or cooked.

The best ways to store the catfish in the freezer are

  • Method 1: Wrap fish with their original store-packing in heavy-duty foil.
  • Method 2: Put the catfish in a zip lock bag with one inch of water, zip the bag, press to remove the air outside the bag.
