How to Remove the Fishy Smell from Saltwater Fish Effectively

Saltwater fish are highly nutritious and rich in essential fatty acids, but they often carry a distinct fishy odor that many people find unpleasant. Compared to freshwater fish, sea fish tend to have a stronger smell due to their higher fat content and the natural compounds in their tissues. If not prepared properly, this odor can linger and reduce the overall flavor of your dish.
Here are a few simple yet effective methods to eliminate the fishy smell from saltwater fish and make your meals more appetizing.

1. Using Salt to Remove the Fishy Smell

After buying the fish, clean it thoroughly—remove the gills, intestines, and scales, then rinse it with clean water. Sprinkle a small handful of coarse salt over the entire fish and gently rub it in. Let it sit for about 15 minutes.

Salt not only helps remove the fishy odor but also tightens the flesh, making the fish firmer and less likely to break apart during cooking. After marinating, rinse the fish again with clean water to remove any excess salt and slime.

👉 Tip: Don’t overuse salt, as it may make the fish too salty and affect the seasoning later when you cook. For large fish, you can combine salt with a little rice wine for an even cleaner taste.

2. Removing Odor with Lemon or Vinegar

Both lemon and vinegar contain natural acids that can neutralize unpleasant smells and break down the mucus on the fish’s surface.

To use vinegar: Place the cleaned fish in a bowl, pour in a moderate amount of vinegar, and rub gently to remove the slimy layer. Rinse thoroughly with water afterward.

If you prefer using lemon: Cut the lemon into small pieces and rub it all over the fish. The lemon’s acidity and essential oils help eliminate odors while adding a refreshing scent. Leave the fish for a few minutes before rinsing and patting dry prior to cooking.

👉 Extra tip: Lemon juice also helps keep the fish’s flesh whiter and firmer when cooked.

3. Using Rice Water (Water from Rinsed Rice)

Washing fish with rice water is a traditional and eco-friendly technique that’s been passed down through generations.

After cleaning the fish, soak it in rice water (the cloudy water from rinsing rice) mixed with a pinch of salt for about 10 minutes. Then rinse again with fresh water and drain.

Rice water contains starch and certain enzymes that help absorb and neutralize odors naturally, leaving the fish cleaner and fresher.

4. Using White Wine

White wine—or even regular cooking wine—is another excellent ingredient for removing fishy odors. It not only eliminates unwanted smells but also enhances the flavor and aroma of the fish when cooked.

After cleaning, rinse the fish with water and marinate it with a small amount of white wine for 5–7 minutes. Then rinse again before cooking.

👉 Bonus tip: You can also add a splash of wine during cooking, especially in steamed or stir-fried fish dishes, to elevate the overall aroma.

5. Using Aromatic Herbs and Spices

During cooking, use strong aromatic ingredients to mask and balance the fishy smell. Popular options include ginger, garlic, shallots, lemongrass, chili, pepper, dill, Vietnamese coriander (rau răm), and spring onions.

These spices not only remove odors but also enrich the flavor, making your dish more fragrant and appetizing. For instance, grilling fish with lemongrass and chili or steaming it with ginger and dill are both great ways to achieve a delicious and fresh taste.

Final Thoughts

Eliminating the fishy smell from saltwater fish doesn’t require fancy ingredients—just a few simple household items and proper preparation. Whether you prefer natural acids like lemon and vinegar or aromatic spices, these easy tricks can help you enjoy the rich flavors of the sea without the unwanted odor.
