How to Choose Fresh Fish
Buying quality fish is the first step toward a delicious meal. Whether you’re shopping at a seafood market, grocery store, or local fishmonger, look for these signs of freshness.
1. Look at the Eyes
Whole fish should have:
- Bright, clear eyes
- Slightly bulging appearance
- No cloudiness
Cloudy or sunken eyes usually indicate older fish.
2. Check the Smell
Fresh fish should smell clean and mild, similar to the ocean.
Avoid fish that smells:
- Strongly fishy
- Sour
- Ammonia-like
A strong odor is a sign the fish is no longer fresh.
3. Inspect the Flesh
Fresh fish fillets should be:
- Firm
- Moist
- Glossy
- Free of discoloration
Press gently with your finger. The flesh should spring back immediately.
4. Examine the Gills
If buying a whole fish, the gills should be:
- Bright red
- Moist
- Clean
Brown or gray gills suggest the fish has been sitting for too long.

Frequently Asked Questions
How often should I eat fish?
Many health experts recommend eating fish at least twice a week as part of a balanced diet.
Can I cook frozen fish?
Yes. Frozen fish can be cooked directly from frozen in many recipes, though thawing it overnight in the refrigerator often provides more even cooking and better texture.
Should I leave the skin on?
For fish like salmon and trout, leaving the skin on during cooking helps protect the flesh and can become deliciously crispy when pan-seared.
What oil is best for cooking fish?
Neutral oils with a high smoke point, such as avocado oil or canola oil, work well for high-heat cooking. Olive oil is excellent for baking, roasting, or lower-heat sautéing.
Can I marinate fish?
Yes. Because fish is delicate, most marinades only need 15–30 minutes. Longer marinating times, especially with acidic ingredients like lemon juice or vinegar, can change the texture.
