How Long Can Fish Stay Fresh After Catching?

Anglers generally keep fish after catching them for two main reasons which are domestic use or commercial use. Either way, the fish needs to be kept fresh as the meat will spoil within 6-12 hours if it’s not treated properly.

There are various factors that affect how long fish can remain fresh after catching them. So, let’s break down these factors:

Weather conditions – Fish tend to spoil faster when exposed to high degrees of heat or moisture.
Type of Fish – Some fish species can remain fresh longer depending on how oily they are. For example, oily fish species such as sardines can remain fresh for only 3 days while less oily fish species such as trout, tuna, bass, and salmon can remain fresh for up to 5 days.
Treatment – According to the FDA, fish can be stored in a refrigerator for about 2 to 4 days. Wrapping it in airtight packing and freezing it can prolong its life up to 3 months longer. So, if you want to cook the fish at any time, you can just take it out and thaw it.

What Is the Best Way to Keep Trout Fresh After Catching It?

Once you’ve caught a trout that you’re planning to keep and eat, you need to make sure it remains fresh until you get home.

The best way to keep trout fresh is to kill the fish quickly right after you catch it, then place it in a bucket full of ice or an insulated cooler to keep the meat delicious and firm.

Although you can try to keep the trout alive in a bucket of water or a live well, it’s usually better to kill and gut it because the decay process can set in quickly.

You will also need to immediately cut its gills and let it bleed out to get rid of any unpleasant flavors in the blood and preserve only the good flavors in the meat.

Once you have brought your trout catch home, you need to wash it using cold water then clean it thoroughly. After cleaning the fish, wrap aluminum foil, plastic, or waxed paper then put it in the refrigerator.

Freezing the fish will keep it in the best condition for the longest time. You can keep it in an airtight plastic container to block the smell of fish from getting on other items in your freezer. You can also put water in the container so it would freeze and create a solid block of ice around your fish.

Killing trout and gutting them right after catching will help keep them fresh longer.

You can kill trout quickly and humanely using various methods. The easiest and most common method is to insert a knife right behind the trout’s eyes into its brain, remove its gills to let all the blood drain out, then place it in an insulated cooler until you get home to clean it.

How to Clean Trout?

Cleaning your trout thoroughly is crucial as it has a great effect on how the fish will taste. It will also help keep it fresh for an extended period of time.

The longest you can wait to clean your trout after catching it is about 24 hours depending on how you store it.

Now, let’s take a look at the steps you can follow to efficiently clean your trout catch:

Hold the trout with its belly in an upright position then use a sharp knife to make a cut from its anal fins towards its head. Try to keep your blade shallow to avoid damaging the meat.
Cut the head off just before the pectoral fin. This step can be optional as some prefer to cook the trout with the head.
Use pliers to spread the trout’s body open so you can remove all of the entrails then use an old toothbrush to clean out the blood vein that runs along the fish’s spine.
Wash the trout thoroughly from the inside and out using fresh cold water to remove any remains of blood.

To remove the scales, you need to hold the trout firmly by its tail and scrape over its skin several times on both sides of its body using a sharp knife.
