Overview
Swordfish is found throughout the Mediterranean Sea, the Black Sea, and temperate ocean regions worldwide.
In Italy, it’s mainly caught in the Strait of Messina.
Its name comes from the long, sword-like bony bill that extends from its upper jaw.
This impressive fish can grow up to four metres long. Its back is a steely blue-grey, the sides shimmer silver, and the belly is a clean white.
From a culinary perspective, swordfish is prized for its succulent flesh, rich in protein.
Its meat is also packed with essential fatty acids, making it a popular choice for post-operative diets, and it’s commonly sold in steaks, both fresh and frozen.
Nutritional Qualities of Swordfish
Swordfish is a much-loved delicacy worldwide. Beyond its delicious taste, its flesh is highly nutritious, brimming with protein, vitamins, and vital minerals.
Firstly, swordfish provides a generous helping of high-quality protein. A 100-gram portion offers around 25 grams of protein, which supports muscle repair and growth. The protein is also easily digestible, allowing the body to make the most of it for cellular functions.
Swordfish is an excellent source of omega-3 fatty acids, essential for heart and brain health, with significant amounts present in its flesh. However, it’s worth noting that swordfish can contain higher levels of mercury, so it’s best enjoyed in moderation.
It’s also rich in important vitamins and minerals, including vitamin B12, which supports a healthy nervous system, and vitamin D, crucial for bone health and immune function. Additionally, swordfish provides iron, magnesium, and selenium—nutrients essential for overall wellbeing.
Finally, swordfish is low in saturated fat and calories, making it a great choice for those aiming to maintain a balanced diet and manage their weight.
Seasonality
Swordfish doesn’t have a strict season, as it can be caught year-round in various parts of the world. That said, catches tend to be more plentiful during certain times depending on the region.
For instance, in parts of the Mediterranean, swordfish are more commonly caught in the summer months when the waters warm. Conversely, in some areas of the Atlantic Ocean, fishing peaks in winter and spring as the fish migrate to cooler waters.
Seasonality also depends on local fishing practices and resource management. In some regions, fishing is restricted during certain periods to allow populations to reproduce and replenish.
Overall, swordfish is available throughout the year, thanks in part to its ability to endure long journeys and the widespread use of freezing for preservation. To support sustainable fishing, it’s important to follow local guidelines and choose swordfish sourced responsibly.
How to Prepare Swordfish
This fish is usually sold already sliced and cleaned, so a quick rinse under cold running water is all that’s needed.
Depending on your recipe, you may choose to leave the skin on or remove it.

Buying Tips
Here are some handy pointers for selecting fresh, top-quality swordfish:
- Choose a trusted fishmonger: Buying from a reputable seller ensures freshness and quality.
- Check the appearance: Fresh swordfish should have shiny, moist skin, clear, bulging eyes, and bright red or pink gills. It should smell fresh and slightly briny, without any off-putting odours.
- Know the source: Verify the fish’s origin to ensure it comes from sustainable and responsibly managed fisheries.
- Ask questions: Don’t hesitate to inquire about the catch date, provenance, and cooking advice.
- Store properly: Keep the fish refrigerated or frozen depending on when you plan to cook it, and aim to consume it within a few days of purchase.
Storage
To keep swordfish fresh at home, follow these simple guidelines to maintain food safety and quality.
- Refrigeration: Fresh swordfish can be stored in the fridge at 0-4°C for up to 2-3 days. Keep it in an airtight container or wrapped tightly in cling film to prevent drying out or absorbing other fridge smells.
- Freezing: Fresh swordfish can be frozen for up to six months. Freeze it as soon as possible after purchase, wrapped securely in cling film or freezer bags to avoid dehydration and odour transfer.
- Thawing: Defrost frozen swordfish slowly in the fridge rather than at room temperature or in warm water to preserve freshness and food safety.
- Freshness check: Before cooking, ensure the fish still looks and smells fresh. When in doubt, it’s safer not to eat it.
- Cooked storage: Once cooked, swordfish can be kept in the fridge for 2-3 days, wrapped in cling film or stored in an airtight container.
