This is a question that many home cooks are likely to ask at some point: How long should I leave fish in a bag before cooking it? The answer is simple, but it may not be what you expect. Fish should be cooked as soon as possible after being stored in a bag, and the best way to do this is by steaming or poaching. If you don’t have time to cook it right away, then fish can be frozen for later use. However, if you have any questions about how long to leave fish in a bag or any other food-related queries, be sure to consult your trusted source—your kitchen manual!

The Problem with Leaving Fish in a Bag

Fish can die quickly if left in a bag, especially if the fish are cold or have not been given enough oxygen. If you plan on leaving your fish in a bag for an extended period of time, it is best to wrap them in ice or place them in a container of water that has been chilled.

How to Store Fish Safely?

If you are storing fresh fish in a bag, it is important to follow these guidelines:

  • Fish should be placed in a clean and dry bag.
  • The fish should be covered by at least two inches of water.
  • The fish should be refrigerated or frozen after being stored in a bag.

The Types of Fish that are Best for Storing

There are a few different types of fish that can be stored in bags, depending on their size and the condition of the fish.

  • Fill a clean bag half way with water and leave the fish in it for no more than two hours. This will help reduce the chances of fish disease.
  • After two hours, change the water and add fresh oxygen if needed.
  • Remove any skin and bones that have floated to the top of the water.
  • Store the bagged fish at room temperature, away from direct sunlight or heat sources.


When it comes to fish, most people would agree that fresh is best. However, many of us find ourselves in situations where we can’t get to a grocery store or our local fishmonger as soon as we want. In these cases, how long do you typically keep fish in the fridge before cooking or eating them? The answer varies depending on the type of fish and the temperature at which it was stored, but generally speaking, most people would say that if you have fresh fish that has been refrigerated within two hours of being caught (or frozen within three months), it can be cooked or eaten right away without any problems.
