Swordfish, also known as broadbills, are a prized catch among anglers and a delicacy in many cuisines. However, not all swordfish are created equal. With the increasing demand for sustainable and responsibly sourced seafood, it’s essential to know how to identify a good swordfish. In this article, we’ll delve into the world of swordfish, exploring the characteristics, features, and certifications that distinguish a high-quality swordfish from a mediocre one.
Understanding Swordfish
Before we dive into the specifics of identifying a good swordfish, let’s take a brief look at the biology and ecology of these magnificent creatures.
Swordfish (Xiphias gladius) are a species of billfish that inhabit the warm and temperate waters of the Atlantic, Pacific, and Indian Oceans. They are apex predators, feeding on a variety of fish, squid, and crustaceans. Swordfish are known for their distinctive “sword-like” bill, which they use to hunt and defend themselves.
Swordfish Life Cycle
Swordfish are a migratory species, with adults traveling long distances to reach their spawning grounds. They are a relatively fast-growing species, with some individuals reaching maturity in as little as 2-3 years. However, the average lifespan of a swordfish is around 5-7 years.
Size and Weight
Swordfish can grow to impressive sizes, with the largest individuals reaching up to 14 feet (4.3 meters) in length and weighing over 1,100 pounds (500 kg). However, the average size of a commercially caught swordfish is around 50-100 pounds (23-45 kg).
Characteristics of a Good Swordfish
So, what makes a swordfish a good catch? Here are some key characteristics to look out for:
Freshness
Freshness is a critical factor in determining the quality of a swordfish. A fresh swordfish should have:
- A pleasant, slightly sweet smell
- Firm, glossy flesh
- Bright, clear eyes
- A slightly firm texture
Color and Appearance
A good swordfish should have a uniform grayish-brown color, with a slightly lighter belly. The flesh should be firm and glossy, with a subtle sheen.
Texture and Firmness
The texture and firmness of a swordfish are essential indicators of its quality. A good swordfish should have:
- Firm, meaty flesh
- A slightly springy texture

What are the key characteristics of a good swordfish?
A good swordfish should have a firm texture and a slightly sweet smell. The flesh should be a deep pink or white color, depending on the type of swordfish. The skin should be smooth and shiny, with no signs of damage or discoloration. The eyes should be bright and clear, and the gills should be a deep red color. The swordfish should also have a good balance of fat and lean meat, which will affect its flavor and texture.
In addition to these physical characteristics, a good swordfish should also be sustainably sourced and handled properly. Look for swordfish that has been caught using eco-friendly methods and has been stored and transported at the right temperature. This will help ensure that the swordfish is not only delicious but also safe to eat.
How can I tell if a swordfish is fresh?
There are several ways to tell if a swordfish is fresh. One of the most important things to check is the smell. Fresh swordfish should have a slightly sweet smell, while old or spoiled swordfish will have a strong, fishy smell. You should also check the eyes, which should be bright and clear. If the eyes are cloudy or sunken, the swordfish may be old or spoiled.
Another way to check the freshness of a swordfish is to look at the flesh. Fresh swordfish should have a firm texture and a deep pink or white color. If the flesh is soft or discolored, the swordfish may be old or spoiled. You can also check the gills, which should be a deep red color. If the gills are pale or discolored, the swordfish may be old or spoiled.
What is the difference between a male and female swordfish?
Male and female swordfish can be difficult to tell apart, but there are a few key differences. Male swordfish tend to be smaller than females and have a more pointed bill. They also tend to have a more vibrant color pattern, with a darker back and lighter belly. Female swordfish, on the other hand, tend to be larger and have a more rounded bill.
Female swordfish also tend to have a higher fat content than males, which can affect the flavor and texture of the meat. However, the difference in flavor and texture between male and female swordfish is relatively small, and both can be delicious if cooked properly. It’s worth noting that swordfish are often sold without being sexed, so it may not be possible to tell whether a particular swordfish is male or female.
How can I store swordfish to keep it fresh?
To keep swordfish fresh, it’s essential to store it properly. Swordfish should be stored in the refrigerator at a temperature of 40°F (4°C) or below. It’s also important to keep the swordfish away from strong-smelling foods, as it can absorb odors easily. You can store swordfish in a sealed container or wrap it tightly in plastic wrap or aluminum foil.
If you don’t plan to use the swordfish within a day or two, you can also freeze it. Swordfish can be frozen for up to six months, but it’s essential to freeze it properly to preserve the quality. Make sure to wrap the swordfish tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. When you’re ready to use the swordfish, simply thaw it in the refrigerator or under cold running water.
Can I eat swordfish raw?
Swordfish can be eaten raw, but it’s essential to handle it properly to minimize the risk of foodborne illness. Swordfish can contain parasites, such as Anisakis, which can cause anisakiasis. To minimize the risk of anisakiasis, it’s essential to freeze the swordfish at a temperature of -4°F (-20°C) for at least seven days. This will kill any parasites that may be present.
Even if the swordfish has been frozen, it’s still essential to handle it properly to minimize the risk of foodborne illness. Make sure to wash your hands thoroughly before and after handling the swordfish, and make sure to cut it on a clean surface. You can eat swordfish raw as sashimi or sushi, but make sure to follow proper food safety guidelines.
How do I cook swordfish to make it tender?
Swordfish can be a bit tricky to cook, as it can become tough and dry if overcooked. To make swordfish tender, it’s essential to cook it properly. One of the best ways to cook swordfish is to grill it or pan-fry it. This will help to lock in the moisture and make the swordfish tender and flavorful.
When cooking swordfish, make sure to cook it to the right temperature. Swordfish should be cooked to an internal temperature of at least 145°F (63°C) to ensure food safety. You can also use a meat thermometer to check the internal temperature. Don’t overcook the swordfish, as this can make it tough and dry. Instead, cook it until it’s just cooked through, then let it rest for a few minutes before serving.
Is swordfish a sustainable seafood choice?
Swordfish can be a sustainable seafood choice, but it depends on the fishing method and location. Some swordfish fisheries are certified as sustainable by organizations such as the Marine Stewardship Council (MSC). These fisheries use eco-friendly fishing methods that minimize bycatch and protect the marine ecosystem.
However, not all swordfish fisheries are sustainable. Some fisheries use fishing methods that can harm the marine ecosystem, such as longlining and gillnetting. These methods can result in bycatch and habitat damage, which can harm the environment. To make a sustainable seafood choice, look for swordfish that has been certified as sustainable by a reputable organization such as the MSC.
