When it comes to choosing fish high in omega-3 low in mercury, not all species are created equal. Here are seven top picks that strike the perfect balance between nutrition and safety:

1. Wild Alaskan Salmon

1. • Why It’s Great: Rich in omega-3s, wild-caught salmon has lower mercury levels compared to farmed varieties.
   • Substitutions: Farmed Atlantic salmon (in moderation).
2. Sardines
   • Why It’s Great: Small fish like sardines are loaded with omega-3s and very low in mercury because they’re lower on the food chain.
   • Substitutions: Anchovies or herring.
3. Rainbow Trout

1. Why It’s Great: Similar to salmon but often more affordable, rainbow trout is a fantastic source of omega-3s.
2. Substitutions: Arctic char.
3. Mackerel (Atlantic)
   • Why It’s Great: Packed with flavor and nutrients, Atlantic mackerel is an excellent choice. Avoid king mackerel due to higher mercury content.
   • Substitutions: None recommended; stick with Atlantic varieties.
4. Anchovies
   • Why It’s Great: Tiny yet mighty, anchovies add bold flavor and tons of omega-3s without the mercury risk.
   • Substitutions: Sardines or capers (for flavor).
5. Herring

1. Why It’s Great: Often enjoyed pickled or smoked, herring is another small fish rich in omega-3s and low in toxins.
2. Substitutions: Kippers.
3. Oysters
   • Why It’s Great: While technically shellfish, oysters are incredibly nutrient-dense and contain omega-3s along with zinc and iron.

These fish aren’t just healthy—they’re also versatile enough to fit into almost any dish. Whether you prefer grilling, baking, or tossing them into salads, there’s no wrong way to enjoy them.

Step-by-Step Instructions: How to Prepare These Superstar Fish

Now that you’ve got your list of fish high in omega-3 low in mercury, let’s talk about how to cook them. Here’s a simple breakdown for each method:

Grilling

• Preheat your grill to medium-high heat.
• Pat the fish dry with paper towels and season generously with salt, pepper, lemon juice, and herbs like dill or parsley.
• Place skin-side down on the grill and cook for 4–6 minutes per side, depending on thickness.

Tip: Use a fish spatula to flip delicate fillets without breaking them.

Baking

• Preheat your oven to 375°F (190°C).
• Line a baking sheet with parchment paper and place the fish on top. Drizzle with olive oil and season as desired.
• Bake for 10–15 minutes until flaky and opaque.

Tip: Add slices of lemon or sprigs of thyme directly onto the fish for extra flavor.

Pan-Searing

• Heat a nonstick skillet over medium-high heat and add a splash of olive oil.
• Season the fish and cook for 3–4 minutes per side, ensuring a golden crust forms.

Tip: Finish with a squeeze of fresh lime juice before serving.

Raw Options (Ceviche or Sushi)

• For ceviche, chop the fish into small cubes and “cook” it in citrus juice (like lime or lemon) for 15–20 minutes.
• Serve with diced onions, tomatoes, cilantro, and avocado.

Tip: Only use sushi-grade fish from trusted sources for raw preparations.

Assembly: Pulling It All Together

Once your fish is cooked, it’s time to assemble your dish! Here are some ideas for combining flavors and textures:

• Salads: Flake grilled salmon or trout over mixed greens, cherry tomatoes, cucumbers, and a light vinaigrette.
• Tacos: Fill corn tortillas with seared mackerel, shredded cabbage, salsa, and a dollop of Greek yogurt.
• Pasta Dishes: Toss baked sardines or anchovies with whole wheat pasta, garlic, chili flakes, and olive oil for a Mediterranean twist.

Presentation Tip: Garnish with fresh herbs, edible flowers, or a sprinkle of sea salt for a restaurant-worthy finish.

Storage and Make-Ahead Tips

To keep your fish fresh and flavorful:

• Store raw fish in the coldest part of your fridge for up to two days.
• Freeze portions in airtight bags for up to three months.
• Reheat gently using low heat to avoid drying out the fish.

For make-ahead meals, consider pre-cooking batches of fish and storing them in portioned containers. They reheat beautifully in the microwave or oven.

Recipe Variations: Get Creative!

Don’t be afraid to experiment with different cuisines and flavors. Some fun twists include:

• Asian-Inspired Glaze: Brush salmon with soy sauce, honey, ginger, and garlic before baking.
• Spicy Kick: Top grilled mackerel with a spicy harissa paste or sriracha mayo.
• Breakfast Boost: Poach smoked herring and serve it alongside scrambled eggs and toast.

The possibilities are endless!
