Why Does It Matter If the Fish Is Fresh?
Whether you’re shopping at a supermarket or a local fish market, choosing fresh fish is essential for both taste and safety. Poor-quality fish not only compromises the flavor of your dish but can also pose health risks like food poisoning, especially when eaten raw. Identifying freshness isn’t just about smell—it involves evaluating the eyes, gills, skin, smell, and texture. This guide breaks down the key indicators to help beginners confidently select the freshest fish every time.
1. Are the Eyes Clear and Slightly Bulging?
Fresh fish have clear, bright eyes that slightly protrude from the head. Cloudy, sunken eyes indicate age and deterioration. If the eyes appear dull or milky, it’s best to skip that fish. For many buyers, inspecting the eyes alone can filter out the least fresh options before checking anything else.
2. Do the Gills Look Bright Red Without Slime?
Gently open the fish’s mouth to inspect the gills. Fresh gills are vivid red or pink with a moist but not slimy texture. If the gills appear brownish or gray and emit a strong odor, the fish is past its prime. This is especially important if you plan to eat the fish raw, like in ceviche or sushi.
3. Is the Skin Glossy and the Scales Firmly Attached?
Skin appearance is another visual indicator. Scales should be shiny, tightly attached, and hard to peel off easily. Dull skin or missing patches of scales could mean poor handling or a lack of freshness. A fresh fish should reflect light and feel firm to the touch.
4. Is the Flesh Firm and Bouncy When Pressed?
Press the flesh gently with your fingertip. If it springs back quickly without leaving an indentation, that’s a good sign of freshness. If your finger leaves a dent or the texture feels mushy, the fish has likely started deteriorating. This rule especially applies to whole fish and fillets alike.
5. Does It Smell Like the Ocean—Not Fishy?
Fresh fish smells like sea breeze or marine vegetation, not like strong fishy odors. A sour, ammonia-like, or pungent smell is a major red flag. Trust your nose—if the aroma seems off in any way, it’s better to walk away.
6. Check the Tail: Is It Moist and Intact?
While people often overlook the tail, its condition can reveal how well the fish has been stored. A fresh fish will have a supple, moist tail. If the tail looks dry, frayed, or discolored, it’s a sign that the fish has been out for too long or wasn’t properly refrigerated.
7. Has the Fish Been Soaking in Water?
Avoid fish displayed in standing water or melted ice. Prolonged contact with water can make the flesh soggy and accelerate spoilage. Choose fish that are kept dry on ice or in well-ventilated refrigerated sections.
8. Is the Fish Whole or Gutted—And Why It Matters
Fish sold whole often retains freshness longer because internal organs can protect the flesh from air exposure and bacterial growth. However, if the fish is already gutted, make sure it hasn’t dried out around the stomach area. Gutting shortens shelf life, so consume processed fish sooner rather than later.
9. Are You Buying Seasonal Fish?
Fish taste better in their peak season due to optimal fat content and flavor development. For instance, mackerel is best in fall, while halibut peaks in spring. Knowing seasonal fish varieties helps ensure you’re not just getting freshness—but also the best flavor possible for the price.
10. Look for Labels Like “Wild-Caught Today” or Certification Tags
Labels can be your friend. Look for phrases like “fresh catch,” “harvested today,” or certifications such as MSC (Marine Stewardship Council). At large grocery chains, also pay attention to harvest methods, country of origin, and sell-by dates. These details give useful clues about the product’s journey and quality.
A Quick Checklist to Evaluate Freshness
- Eyes: Clear, bulging
- Gills: Bright red, no slime

Spending just one minute with this list before you buy can prevent disappointment—and potentially save your health. The more you practice, the more intuitive it becomes to identify quality fish at a glance.
Final Thought: Learning to Judge Fish by Sight and Smell
Ultimately, developing your own judgment through repeated experience is the best way to master fish selection. Starting with structured tips is helpful, but over time, your senses will become fine-tuned to subtle differences in texture, aroma, and appearance. Think of each visit to the market as a chance to sharpen your skill—because knowing how to pick the right fish pays off every time you cook.
