How Long Before Fish Goes Bad After Catching?

Freshly caught fish is a delectable treat that seafood lovers often crave. However, it is essential to consume fish before it goes bad to avoid any health risks. The shelf life of fish after catching can vary depending on several factors such as storage conditions and the type of fish. In this article, we will explore how long fish remains fresh after catching and provide answers to some frequently asked questions regarding fish storage.

The shelf life of fish primarily depends on its freshness at the time of catching. Generally, fish starts to spoil as soon as it is caught, and the deterioration process begins with the enzymatic breakdown of proteins. Factors such as temperature, exposure to air, and the type of fish influence how quickly this process occurs.

Below are some common types of fish and their approximate shelf life after catching:

1. Whitefish (e.g., cod, haddock): 2-3 days
2. Salmon: 3-4 days
3. Tuna: 1-2 days
4. Shellfish (e.g., shrimp, crab): 1-2 days
5. Smaller fish (e.g., sardines, anchovies): 1-2 days

It is important to note that these timeframes are estimates, and the freshness of the fish may vary based on the conditions mentioned earlier. To ensure the longest possible shelf life, it is crucial to handle and store fish properly.
