How Long is Fish Good in the Fridge

If you’re a seafood lover, you probably know the importance of keeping your fish fresh. But how long is fish good in the fridge? It’s a question that many people often wonder about, and the answer is not always straightforward.

In this blog post, we’ll take a closer look at the factors that affect the shelf life of fish, general guidelines for refrigerating fish, signs of spoiled fish, and tips for reducing food waste.

Whether you’re a home cook or a seafood enthusiast, understanding how long your fish will last in the fridge can help you make the most out of your seafood while keeping your meals safe and delicious.

Factors Affecting the Shelf Life of Fish


Temperature plays a significant role in determining the shelf life of fish. Keeping fish at low temperatures slows down the growth of bacteria and helps to preserve its freshness. The ideal temperature for storing fish in the fridge is between 32°F (0°C) and 39°F (4°C). It is important to note that the temperature in your refrigerator should be set to maintain this range consistently.

Type of fish

Different types of fish have varying shelf lives. Some fish, such as fatty fish like salmon or mackerel, have a shorter shelf life compared to lean fish like cod or sole. This is because fatty fish contain higher levels of unsaturated fats, which can become rancid more quickly. It’s important to consider the specific characteristics of the fish you’re storing to determine its optimal storage time.

Storage conditions

Proper storage conditions are essential for maximizing the shelf life of fish. Here are some key points to keep in mind:

  • Freshness: The fresher the fish, the longer it will last. Purchase fish from reputable sources and ensure that it is handled and stored correctly before reaching your fridge.
  • Packaging: Fish should be tightly wrapped in plastic or stored in airtight containers to prevent exposure to air and minimize the risk of bacterial contamination. This will also help prevent odors from permeating other foods in the refrigerator.
  • Moisture: Fish should be stored in a slightly damp environment to maintain its moisture content. You can place the fish on a tray lined with damp paper towels or cover it with a damp cloth.
  • Separation: To prevent cross-contamination and maintain the quality of other foods, store fish in a separate compartment or in a sealed container on the lowest shelf of the refrigerator. This will minimize the risk of fish juices coming into contact with other items.
  • Use-by dates: If you have purchased pre-packaged fish with a use-by date, make sure to consume it before that date for optimal freshness and safety.

By considering these factors and following proper storage practices, you can ensure that your fish stays fresh and safe to consume for an extended period. Remember to always use your senses of sight and smell to assess the quality of fish before cooking or consuming it. When in doubt, it’s better to err on the side of caution and discard any fish that appears or smells spoiled.

How Long Fish Can Be Safely Stored In The Fridge

The storage time for fish in the refrigerator depends on various factors, including the type of fish, its freshness, and storage conditions. As a general guideline:

  • Fresh lean fish (e.g., cod, sole): Can be stored in the refrigerator for up to 2-3 days.
  • Fresh fatty fish (e.g., salmon, mackerel): Can be stored in the refrigerator for up to 1-2 days.
  • Cooked fish: Can be refrigerated for 3-4 days.

It’s important to note that these time frames are estimates, and the freshness of the fish should always be assessed visually and by smell before consuming it.

Tips For Properly Storing Fish In The Fridge

To maximize the shelf life and maintain the quality of fish in the refrigerator, consider the following tips:

  • Store fish at the appropriate temperature: Set your refrigerator to maintain a temperature between 32°F (0°C) and 39°F (4°C) to slow down bacterial growth.
  • Wrap fish tightly: Wrap fish in plastic wrap or store it in airtight containers to prevent air exposure and reduce the risk of contamination.
  • Use proper packaging materials: If the fish is sold in a vacuum-sealed package, it’s best to keep it in its original packaging until ready to use. Otherwise, use food-grade plastic wrap or bags.
  • Separate fish from other foods: Store fish in a separate compartment or in a sealed container on the lowest shelf to prevent cross-contamination and avoid fish odors permeating other foods.
  • Avoid overcrowding: Do not stack or overcrowd fish in the refrigerator, as this can inhibit proper air circulation and lead to faster spoilage.
  • Don’t wash fish before storing: Washing fish before refrigeration can increase moisture content and promote bacterial growth. It’s best to wash fish just before cooking.

Signs of Spoiled Fish


Spoiled fish may have visible signs of deterioration. Look for:

  • Discoloration: The fish may appear dull or have a yellowish or brownish tint.
  • Fading of vibrant colors: The natural colors of the fish may fade or become dull.
  • Dryness or stickiness: The flesh of the fish may appear dry or sticky to the touch.
  • Deterioration of eyes and gills: The eyes may be cloudy or sunken, and the gills may appear slimy or discolored.


Spoiled fish has a distinct and unpleasant odor. If the fish emits a strong, sour, or ammonia-like smell, it is likely spoiled and should be discarded.


Fresh fish should have a firm texture. Signs of spoilage in terms of texture include:

  • Softness: The flesh may feel mushy or lose its firmness.
  • Sliminess: The fish may feel excessively slimy or slippery.

If you notice any of these signs, it is best to err on the side of caution and avoid consuming the fish, as it may pose a health risk.

Remember to prioritize food safety when storing and consuming fish to ensure a delightful and risk-free dining experience.

Tips for Reducing Food Waste

Plan your meals to use up fish before it goes bad

  • Check the freshness: Before purchasing fish, assess the freshness of the available options. Choose fish with a longer shelf life to give yourself more time to consume it.
  • Meal planning: Incorporate fish into your meal plan for the week. Consider the storage time for each type of fish and plan to consume it within that timeframe.
  • FIFO method: FIFO stands for “First In, First Out.” When storing fish in the refrigerator, place the newest purchases behind the older ones. This way, you are more likely to use the older fish before it spoils.

Creative recipes for using up leftover fish

  • Fish Tacos or Wraps: Flake the leftover fish and use it as a filling for tacos or wraps. Add fresh vegetables, salsa, and a flavorful sauce for a delicious and quick meal.
  • Fish Cakes or Patties: Combine leftover fish with mashed potatoes or breadcrumbs, along with herbs and spices, to make fish cakes or patties. Pan-fry or bake them for a tasty and versatile dish.
  • Fish Chowder or Soup: Use leftover fish to make a comforting chowder or soup. Combine it with vegetables, broth, and seasonings to create a flavorful and hearty meal.
  • Fish Salad: Flake the fish and use it as a topping for salads. Add fresh greens, vegetables, and a tangy dressing for a light and refreshing meal option.
  • Fish Fried Rice: Incorporate leftover fish into a stir-fried rice dish. Sauté the fish with vegetables, rice, and soy sauce for a flavorful and satisfying one-pan meal.

Remember, when using leftover fish, ensure that it is still within its safe consumption period and doesn’t exhibit signs of spoilage. Always follow proper food handling and storage practices to maintain food safety.

By planning your meals and getting creative with recipes, you can reduce food waste and make the most of your fish while enjoying delicious meals.
