Fish dishes are considered a staple in many diets across the globe. They’ve earned a well-deserved place in our cuisine for their taste, variety, and undeniable health benefits. However, if you want to broaden your seafood palate or buy whole fish for a sumptuous meal, the sheer number of options can leave you needing clarification. This guide is here to demystify the vast world of seafood by offering insights into different types of fish.

The Nutritional Importance of Fish

Before diving into the specifics, let’s take a moment to understand why seafood, mainly fish, is essential to our diet. The primary reason is their high-quality protein content, which is easily digestible and contains all the essential amino acids our bodies require. They are also an excellent source of omega-3 fatty acids, which are beneficial for brain health and reducing inflammation.

Popular Types of Fish

Now let’s cast our nets a bit wider and explore some popular types of fish you might encounter at your local fish market or restaurant.


Salmon is a fatty fish highly prized for its rich, buttery taste. There are different types of salmon, like Atlantic, Pacific, and farm-raised, each with subtle differences in taste and texture. Salmon is an excellent omega-3 fatty acids, Vitamin D, and protein source.


Whether raw in sushi or seared as a steak, tuna is another favourite for many seafood lovers. It’s a lean, meaty fish with a distinct taste. Tuna is an excellent source of protein and contains a good amount of Vitamin B12 and selenium.


Snapper is a lean, firm white fish with a mildly sweet flavour, making it versatile for various dishes. Red snapper is the most popular variety, but there are several others, like grey, yellowtail, and mutton snapper. Snapper is an excellent Vitamin B12, potassium, and lean protein source.


Cod is a white fish known for its mild flavour and flaky texture. It’s popular in fish and chips and other battered fish dishes. It’s high in protein and low in fat, making it an excellent choice for health-conscious consumers.

Sustainable Seafood Consumption

Understanding the different types of fish also entails understanding their sustainability. It’s important to note that overfishing is a significant problem affecting many fish species worldwide. Therefore, it’s crucial to make sustainable choices when buying fish. Look for certifications like the Marine Stewardship Council (MSC) logo on seafood products, indicating they come from sustainably managed fisheries.

Cooking Different Types of Fish

Now that you have a grasp on the different types of fish, it’s time to cook them up. Fatty fish like salmon and tuna can be grilled, baked, or pan-fried, as their oils keep them moist. On the other hand, lean fish like snapper and cod can be steamed, poached, or cooked en papillote to prevent them from drying out.

Benefits of Buying Whole Fish

Buying whole fish instead of pre-cut fillets can benefit your cooking experience. For one, it can be more cost-effective, as filleted and deboned fish often have a higher price tag due to the extra processing. Plus, you can utilise every part of the fish, making for a more sustainable approach to cooking. Not to mention, you’ll have the assurance of freshness, as it’s easier to tell if a whole fish is fresh based on its appearance and smell.

Seafood Storage and Safety

Properly storing and handling seafood is crucial to maintaining its quality and ensuring food safety. Fresh fish should be refrigerated as soon as possible and, ideally, consumed within two days. If you’re planning to wait to cook it, freezing is a viable option. Remember to wrap the fish tightly to prevent air exposure. When ready to use, defrost it in the refrigerator to ensure it stays at a safe temperature.

Beyond Fish: Exploring Other Types of Seafood

While this guide has primarily focused on fish, the seafood category includes an array of other delicious options like shellfish (prawns, oysters, mussels), crustaceans (crabs, lobsters), and molluscs (squid, octopus). Each offers a unique set of flavours, textures, and a universe of recipe possibilities.


Prawns are a favourite in many cuisines for their sweet, slightly briny flavour. They’re excellent grilled, sautéed, or added to pasta and stir-fries. Prawns are rich in protein, vitamin B12, and selenium.


Renowned for its luxurious taste and texture, lobster is a treat for any seafood lover. It’s delicious steamed, boiled, or grilled and served with melted butter. Lobsters are high in protein, vitamin B12, and zinc.


Mussels are bivalve molluscs with a slightly sweet, delicate flavour. They’re typically steamed and served in a sauce or broth. Mussels are an excellent source of protein, vitamin B12, and iron.


Exploring the world of seafood is an adventure for your taste buds, offering a fantastic range of flavours, textures, and nutritional benefits. By understanding the various types of seafood, from different fish to shellfish and more, you can diversify your culinary repertoire and make informed choices about sustainability and health.
