How to Choose Fresh Fish at the Grocery Store or Fish Market

Choose fish from a cold, clean-smelling display, then check its smell and the cues that fit its form: eyes and gills for whole fish, firmness and edges for fillets, and package condition for frozen fish. Color alone cannot tell you whether fish is fresh. Buy seafood near the end of your shopping trip and keep it cold on the way home.

Start with the display and smell

• Check the temperature: Choose seafood that is refrigerated or resting on a thick bed of fresh ice. If the seafood counter or freezer case smells fishy, NOAA advises shopping elsewhere.
• Consider the seller: NOAA recommends buying from knowledgeable, reputable dealers with a record of proper handling. Ask how the fish was handled if you have questions.
• Smell the fish: It should smell fresh and mild, not fishy, sour, or like ammonia. If you are unsure, NOAA says you can ask the seller to rinse it under cold water and smell it again.

What to check on whole fish

• Eyes: Look for clear, shiny, full eyes. Cloudy or sunken eyes can indicate loss of freshness.
• Gills: Gills should be bright red or pink and free of an unpleasant odor.
• Flesh: It should feel firm. Check smell and display conditions as well; no single visual cue settles the question.

What to check on fillets and steaks

• Firmness: Flesh should feel firm and spring back when gently pressed.
• Cut and edges: Look for a fresh-cut appearance, without dried edges, darkening, or brown or yellow discoloration.
• Smell: The odor should remain mild and fresh, not fishy, sour, or ammonia-like.

Do not judge freshness by color alone

Fish color varies for reasons that are not a simple measure of freshness. The FDA notes that diet, environment, carbon-monoxide color fixation, and other packaging processes can affect color. A vivid hue does not prove that fish is fresh, and a less vivid appearance alone does not prove that it has spoiled.

Previously frozen fish can still be a good choice

“Fresh” does not automatically mean never frozen. Freezing can make a fillet less shiny, and previously frozen fish may lack some classic visual signs, such as vivid bloodlines or especially firm flesh. NOAA and FDA guidance still points shoppers to smell: it should be mild and fresh, not fishy, sour, or rancid. Do not reject an otherwise suitable fillet solely because it has been frozen or looks less shiny.

How to check packaged frozen fish

• Avoid packages that are torn, open, or crushed.
• Fish should be solidly frozen, not bendable.
• A heavy covering of frost or ice crystals may indicate extended storage or thawing and refreezing.

Compare fish by its form, not by a single sign

When choosing between options, use the checks suited to each product and consider whether it has been kept cold. Color is not a reliable ranking shortcut.

Keep fish cold after buying

NOAA Fisheries recommends buying seafood last and bringing a cooler to transport it home. An insulated grocery cooler bag with cold packs can help with the trip, but it does not assess freshness at the counter.

At home, NOAA advises storing seafood in the coldest part of the refrigerator, as close to 32°F as possible. It gives two days after purchase as a general rule of thumb for using fresh fish, while noting that shelf life varies by species. FDA guidance says seafood intended for use within two days should be kept in a clean refrigerator at 40°F or below. These are handling recommendations, not guarantees of freshness or safety.
