20 Super Nutritious Fish to Power Up Your Diet

11. Arctic Char - The Sustainable Salmon Cousin

Resembling salmon and trout, Arctic Char offers a similar delightful flavour profile – rich yet milder than salmon – and a vibrant pink-orange flesh. It's packed with heart-healthy omega-3 fatty acids, high-quality protein, and essential B vitamins. Crucially, Arctic Char is often raised in sustainable aquaculture systems, making it an environmentally sound choice. Its moderate fat content lends a moist, flaky texture perfect for grilling, baking, or pan-searing. For those seeking the benefits of salmonids with a slightly different taste and strong sustainability credentials, Arctic Char is a fantastic and increasingly available option.

12. Sablefish (Black Cod) - The Buttery Delicacy

Don't let the name fool you; Sablefish, often marketed as Black Cod, isn't related to cod. This deep-sea fish boasts an incredibly rich, buttery flavour and a velvety, flaky texture that melts in your mouth. It's exceptionally high in omega-3 fatty acids, even surpassing salmon in some cases, making it phenomenal for heart and brain health. Sablefish is also a good source of vitamin D and B12. Its high oil content makes it forgiving to cook, perfect for smoking, grilling, or baking (like in the classic Nobu miso-marinated dish). It’s a true delicacy offering profound health benefits.
