How to Identify Fresh Fish Before Buying It From the Market
Fresh fish can be identified by checking the eyes, flesh, smell, gills, skin and scales, helping shoppers avoid poor quality seafood and make safer choices.

Buying fish can sometimes be confusing, especially when several varieties are displayed on ice at a market. A fish may look attractive from the outside, but appearance alone does not always tell the full story. Knowing a few simple checks can make it much easier to judge whether the fish is fresh.
Fish is widely valued as a source of protein and omega 3 fatty acids, making it a regular part of many diets. But freshness matters just as much as the type of fish being purchased. Poor quality seafood can develop unpleasant smells and changes in texture, so shoppers should take a moment to examine the fish before paying for it.
Check the eyes first
The eyes are among the easiest things to inspect when buying whole fish. Fresh fish generally has clear, bright and slightly prominent eyes. They should look moist rather than dull or cloudy.
If the eyes appear deeply sunken, cloudy or unusually discoloured, the fish may have been stored for a considerable period. A cloudy appearance by itself does not prove that fish is unsafe, but it can be a useful warning sign when combined with other signs of deterioration.
Press the flesh gently
Texture can provide another useful clue. Gently pressing the thickest part of the flesh should leave it firm and resilient. Fresh flesh should spring back relatively quickly after pressure is removed.
If the flesh feels unusually soft, mushy or leaves a noticeable indentation, shoppers should be cautious. A loose texture together with an unpleasant smell or dull appearance can indicate that the fish is no longer in good condition.
Pay attention to the smell
Smell is perhaps one of the quickest ways to notice that something is wrong. Fresh fish normally has a mild, clean smell associated with the sea or the natural environment from which it came.
A strong ammonia like odour, sour smell or distinctly rotten odour is a reason to avoid the fish. Consumers should not rely on cooking to make poor quality seafood acceptable.
Look at the gills
When buying whole fish, checking the gills can offer another indication of freshness. Fresh gills generally appear moist and naturally red or pink.
Gills that have become very dark, brownish, grey or otherwise discoloured may indicate that the fish has been stored for longer. This check becomes more useful when considered alongside the eyes, smell and firmness of the flesh.
Inspect the skin and scales
Fresh fish usually has skin that looks naturally moist and relatively shiny. The scales should remain firmly attached rather than coming away easily with minimal contact.
If the skin looks excessively dull, damaged or discoloured and the scales fall off easily, shoppers should examine the fish carefully before buying it. These changes can occur as fish loses freshness during storage.
Do not judge fish only by its appearance
Fish displayed on ice can look fresh even when it has been stored for some time. Ice helps maintain a low temperature, but it does not restore freshness once the quality of seafood has started to decline.
Shoppers should therefore use several checks rather than depending on a single sign. Looking at the eyes, feeling the firmness, checking the smell and examining the gills and skin together gives a much better overall picture.
It is also sensible to buy seafood from clean and properly refrigerated sellers. Once purchased, fish should be kept cold and handled safely at home. If the fish has an unusually strong odour or clear signs of spoilage, it is better not to take the risk.
A few seconds of careful checking at the market can help shoppers make a more informed choice and avoid paying for seafood that does not meet their expectations.
