Swordfish (Xiphias gladius), also known as broadbills in some countries, are large, highly migratory, predatory fish characterized by a long, flat, pointed bill. They are a popular sport fish of the billfish category, though elusive. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft), and exceptionally up to depths of 2,234 m.[rx] They commonly reach 3 m (10 ft) in length, and the maximum reported is 4.55 m (14 ft 11 in) in length and 650 kg (1,430 lb) in weight.[rx][rx]

Description

It is the exclusive member of the family Xiphiidae. They are formidable predators. It has acute eyesight which helps them to address prey and its flesh is comprised of white muscle providing energy for sudden bursts of activity when chased its prey. Then swordfish uses its bill to impale or stun its victim, lacerate it into pieces, or might swallow it whole. It feeds during the day mainly on squid but also fish and crustaceans infrequently. It undertakes vertical migrations in the ocean and follows the movement of small fish, shrimp, and squid which moves with changing the intensity of light for avoiding predators. It is unable to maintain a higher body temperature than the temperature of surrounding water. But they have uncommon muscle and brown tissue which warms blood flowing to the eyes and brain that helps to enable them to tolerate the extreme cold of ocean depths. They undertake lengthy seasonal migrations, to cold or temperate waters in summer where it feeds and returns back to warm waters for spawning in autumn.

The spawning occurs year-round in warm equatorial waters and it occurs in cooler regions in spring and summer. The finest spawning grounds are found in the Mediterranean sea, Sicily, and south of the Italian Peninsula. Eggs are found from June to September and juveniles occur throughout the Mediterranean from November to March. The fertilization is external. Female releases buoyant eggs in millions into the water which are fertilized by sperm secreted by males. Larvae hatch from fertilized eggs. In the first year of life, larvae grow at an exceptional rate reaching 90 centimeters long. Female reaches maturity at 150 centimeters and male around 100 centimeters.

It is the fast-swimming predator with a flat, long, and sword-like bill used to impale and slash its prey. It has a long and cylindrical blackish-brown body fading gradually to a light brown underside. The body tapers to large anal fins along with a high dorsal fin enabling efficient cruising. The adult is scaleless and has no teeth. Females live longer and grow larger in comparison to males.

Reproduction

Throughout the year, spawning occurs in equatorial water but at higher latitudes during spring and summer. As external fertilization takes place, solitary males and female pairs during spawning. The egg varies from and 29 million in a 2,72,000 g female and 1 million to 16 million in 1,68,000 g female. The spawning occurs in the Atlantic Ocean at depths between 0 and 75 m with temperatures around 23 °C and salinity of 33.8 to 37.4 ppt. But in the Pacific Ocean spawning occurs in water having a temperature of 24°C or more.

Appearance

  • Swordfish has a long, flattened bill that looks like a sword, as their name implies.
  • They have a stout, rounded body and large eyes.
  • Their first dorsal (back) fin is tall and crescent-shaped. Their second dorsal fin is much smaller.
  • Their anal fins (on their belly) are similar in shape to the dorsal fins but are smaller.
  • They have a broad, crescent-shaped tail.
  • Their color is darkest on top, generally black or brown, and fades to a lighter color below.

Biology

  • Atlantic swordfish is one of the fastest predators in the ocean. Their streamlined body allows them to swim at high speeds, up to 50 mph.
  • They grow quickly and reach a maximum size of about 1,165 pounds. However, the average size caught in the fishery is 50 to 200 pounds.
  • Swordfish live about 9 years.
  • Females are able to reproduce between 4 and 5 years of age. Depending on their size, females can produce anywhere from 1 million to 29 million eggs.
  • They spawn multiple times throughout the year in warm tropical and sub-tropical waters.
  • In the western North Atlantic, they spawn south of the Sargasso Sea and in the upper Caribbean from December to March, and off the southeast coast of the United States from April through August.
  • Swordfish feed on a variety of fish and invertebrates such as squid.
  • They capture prey by slashing their bill back and forth, stunning or injuring prey in the process.
  • They have developed unique characteristics, such as a special eye muscle and a heat exchange system that allows them to swim in deep, cold water in search of prey.
  • Swordfish feed at the top of the food chain and are rarely preyed on by other animals. Sharks and larger predatory fishes may sometimes eat juvenile swordfish.

Where They Live

  • Swordfish are found around the world in tropical, temperate, and sometimes cold waters of the Atlantic, Indian, and Pacific Oceans.
  • They are found in the Gulf Stream of the Western North Atlantic, extending north into the Grand Banks of Newfoundland.
  • North Atlantic swordfish annually migrate thousands of miles along the eastern seaboard of the United States and Canada and also in the eastern Atlantic along Africa and Europe.

Fishery Management

  • NOAA Fisheries, through the Atlantic Highly Migratory Species Management Division, manage swordfish in the North Atlantic.
  • Managed under the 2006 Consolidated Atlantic Highly Migratory Species Fishery Management Plan:
    • Permits are required.
      • Pelagic longline and some hand gear permits are limited access permits, which means that the number of available permits restricts the number of vessels fishing for swordfish.
      • There are also commercial open access permits for hand gear, with the exception of buoy gear.
    • Annual catch limits.
    • Minimum size requirements and lending restrictions.
    • Reporting requirements documenting catch, fishing activities, and sales.
    • Required to carry at-sea fisheries observers upon request.
    • Compliance guides are available for all commercial and recreational regulations across Atlantic highly migratory species fisheries.
  • Highly migratory species, such as swordfish, have complicated management that requires international cooperation.
    • A swordfish that is off Massachusetts one week could be caught off the coast of Canada the next. These resources must be managed both in the United States and at the international level.
    • NOAA works with the International Commission for the Conservation of Atlantic Tunas (ICCAT) on the management of international species, like swordfish.
      • NOAA sets regulations for swordfish based on U.S. science, conservation and management, and recommendations from ICCAT.

Harvest

  • Commercial fishery:
    • In 2019, commercial landings of North Atlantic swordfish totaled more than 2.9 million pounds and were valued at more than $8.9 million, according to the NOAA Fisheries commercial fishing landings database. These figures may not match other agency sources of data due to confidential information.
  • Gear types, habitat impacts, and bycatch:
    • Fishermen mainly use pelagic longline gear to harvest swordfish. They may also use rod-and-reel, harpoon, and buoy gear.
    • Pelagic longline gear and handgear have no impact on habitat because they’re used in the water column and don’t come into contact with the ocean floor.
    • Handgear used to catch swordfish is very selective and bycatch is minimal.
    • NOAA Fisheries has taken the following additional measures to prevent bycatch and sustainably manage this fishery. Fishermen are:
      • Required to use large circle hooks and certain types of bait that limit gear interactions with sea turtles. Circle hooks are specifically designed to minimize the damage caused by hooking, giving animals that are captured and released a better chance at survival.
      • Trained and certified to use special techniques to safely de-hook and release incidentally caught turtles.
      • Required to stop fishing and move 1 nautical mile if they encounter a protected species.
      • Required to protect pilot whales and Risso’s dolphins when fishing in the Mid-Atlantic Bight by limiting the length of their lines to 20 nautical miles and posting marine mammal handling/release guidelines on their vessels. In addition, if fishing in the Cape Hatteras Special Research Area, pelagic longliners must contact NOAA Fisheries at least 48 hours prior to a trip and carry observers if requested.
      • Required to use weak hooks in the Gulf of Mexico to reduce incidental catch of bluefin tuna, and are prohibited from using live bait to reduce bycatch of billfish.
      • Restricted from areas in the Gulf of Mexico to reduce bycatch of all species.
      • Required to carry vessel monitoring systems onboard their boats to ensure compliance with regulations.
      • Required to carry at-sea fisheries observers upon request. NOAA Fisheries reviews observer data to monitor protected species interactions and takes appropriate action as necessary.

Recreational fishery:

  • Recreational fishermen have fished for swordfish off the East Coast since the 1920s.
  • Permits are required.
  • Minimum size requirement and catch limits.
  • Certain areas are closed to fishing during certain times of the year.
  • Recreational fishermen must also report their swordfish catch by web, mobile app, or by phone at 888-872-8862. If they release the fish, they must release it without removing it from the water in a manner that ensures it has a good chance of survival.
  • Compliance guides are available for all recreational regulations across Atlantic highly migratory species fisheries.

Health Benefits of Swordfish

Let us discuss the health benefits that Swordfish offers:

  1. Vitamin B complex – Vitamin B complex assists in converting food into energy, production of red blood cells, and maintaining efficient metabolism. The serving size of 3 ounces grants 36% of the daily value of Vitamin B6 and nearly 50% of niacin or Vitamin B12. Moreover, it contains 5.2% of the regular amount of thiamine and riboflavin.
  2. Strengthen bones – A diet rich in calcium strengthens bones and teeth. Consume swordfish steak with sources of calcium such as tofu, cheese, and milk to achieve the desired intake. Additionally, swordfish have a high content of fat-soluble nutrient Vitamin D that makes the body able to absorb calcium. A diet rich in calcium but low in Vitamin D still poses the risk of brittle, misshapen, and thin bones.
  3. Heart health – A 3-ounce serving of swordfish grants 21.7 grams of protein, 7.2 grams of fat, and 148.6 calories (62 are from fat). Saturated fat also known as unhealthy fat is limited to about 1/5 of the total fat content. Saturated fat causes a buildup of plaque in arteries. The other fats are heart-healthy monounsaturated and polyunsaturated fats lowering the chances of heart attack and stroke. It has 648 mg of DHA (docosahexaenoic acid) and 104 mg of EPA (eicosapentaenoic acid).
  4. Muscle health – Swordfish has a high content of potassium which is an essential mineral or electrolyte critical for the proper functioning of nerves and muscles. Its single serving provides 712 mg of potassium. A diet with high potassium food helps to protect against heart attack and stroke.
  5. Rich in protein – Swordfish has a high content of protein offering 33.5 grams per 6 ounce serving. Protein is essential to maintain healthy hair, skin, and muscles, producing enzymes and transporting oxygen. It also has essential amino acids that are essential for the body as they could not be self-produced. It is required to lower inflammation and reducing the chances of arthritis, heart disease, and cancers.
  6. Counteract free radical damage – A single serving of Swordfish contains 92 micrograms that enhance the function of the thyroid gland and counteract free radicals.
  7. Sound sleep – Swordfish are rich in magnesium that lowers sleep disorders. Magnesium provides a soothing effect on muscles and provides sound sleep. It also promotes duration and quality of sleep.
  8. Normalize blood pressure – Swordfish is an excellent source of omega-3 fatty acids with good amounts of omega-6 that lowers inflammation and maintains normal blood pressure. The regulation of blood pressure reduces strain on the cardiovascular system and promotes heart health. It lowers the chances of atherosclerosis, heart attack, and stroke. It contains healthy amounts of omega-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
  9. Treats Premenstrual Syndrome – Pyridoxine helps to cure premenstrual syndrome that occurs in women which are reduced. It results in loss of sex drive and moodiness. Vitamin B6 helps to cure this condition.
  10. Maintains cholesterol level – The high intake of niacin helps to lower LDL cholesterol and increase HDL cholesterol. It also prevents the thickening of artery walls and atherosclerosis. (rx)
  11. Prevent acne – It prevents acne and regulates testosterone levels in the body. Additionally, it is also involved in collagen synthesis. It normalizes the skin oils and promotes skin health. Zinc promotes the count of white blood cells and lowers the risk of infection. Zinc reduces the appearance of scars. (rx)
  12. Treat cramps – The deficiency of potassium causes cramps in muscles that is known as hypokalemia. The high intake of potassium prevents muscle cramps. (rx)
  13. Provides energy – Sugar is a great source of energy. Vitamin B1 oxidizes the usable form of energy. It plays a vital role in the pyruvate dehydrogenase system that assists in sugar oxidation. Vitamin B1 is essential for the functions of the enzyme system that supports various functions. (rx)
  14. Enhance immunity – Vitamin B1 promotes immunity power by promoting antibodies and reinforce the defense system to counteract infections.
  15. Nervous health – Riboflavin cures nervous ailments such as Alzheimer’s disease, numbness, anxiety, multiple sclerosis, and epilepsy. It helps to treat painful symptoms of Carpal Tunnel Syndrome.
  16. Help Growth – Nowadays, a lot of parents are stimulating their children’s growth by giving them additional supplements. However, it will be better if we stimulate it naturally. Such as giving the kids balanced nutrition, one of the ways to do this is by giving them the swordfish. The contents of vitamin D in it can also help children to grow taller. The health benefits of baby banana can also be an alternative for you to help with, especially, children’s growth.
  17. Strengthening Body’s Immune System – Another benefit of Swordfish is to protect and maintain the body’s immune system. The content of calcipotriol in vitamin D that is produced by the pomfret fish can also function as an immune system modulator. This nutrition is well-fitted for those of you who are easy to catch a cold, flu, cough, or even headache.
  18. Decrease the Risk of Breast Cancer – Breast cancer is one of the diseases that are very difficult to cure. Therefore, we need to take some steps in order to avoid this cancer. This can be done in many ways such as consuming the Swordfish. This fish is capable to prevent cancer cells from multiplying in your body.
  19. Help You Stays Young – Rejuvenating skin to make it stays beautiful and elastic is certainly what every woman always hoping for. One of the tips to do this, is, by consuming foods that contain vitamin D, such as Swordfish. By consuming the fish every day, then the vitamin D can help to rejuvenate your skin and makes it look healthier and fresher. Even the vitamin D2 and D3 types are capable to decrease the risk of skin diseases such as psoriasis.
  20. Osteomalacia Medicine – Osteomalacia is a disease that attacks the tissues of the human body. The cause of this is the abnormality function of tissue when it is processing the development of minerals on the bones. This can make the bones weak and very easy to break, which usually happens in adults. The solution to this disease is by consuming sea fish and food that have vitamin D in them as well as exposing yourself to the sunlight.
  21. Prevent Rachitic – If osteomalacia usually attacks the adults, rachitic is a bone disease that usually attacks the children. The main cause of this disease is lacking vitamin D and minerals in the bones, thus disturbing the development of the bones. The disease will make the bones weak and not strong enough. One of the solutions to this is to let the children consume foods with vitamin D in them such as spot fish and exposure to the sunlight as well.
  22. Decrease Dementia Risk – For those of you who can afford to consume fish every day, this may be a way to decrease the risk of developing dementia such as Alzheimer’s. This disease attacks the memory or storage media since it degrades the brain cells that can make the patient suffer severe memory loss. One of the ways to prevent this is by consuming fish for its omega 3 content (DHA and EPA). It can help stimulate your brain tissues and cells. If you happen to notice some symptoms of dementia within your body or people around you, don’t forget to go consume Swordfish immediately.
  23. Decrease Depression – Consuming the Swordfish every day will allow you to decrease the risks of depression.

Easy grilled swordfish recipe that utilizes a delicious Mediterranean marinade with cumin, fresh garlic cloves and more. But you don’t even need to leave it in the marinade too long! Just a few minutes while your grill is heating!

INGREDIENTS

  • 6 to 12 garlic cloves, peeled
  • ⅓ cup extra virgin olive oil
  • 2 tablespoon fresh lemon juice, more for later
  • 1 teaspoon coriander
  • ¾ teaspoon cumin
  • ½ to 1 teaspoon sweet Spanish paprika
  • ¾ teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • 4 swordfish steaks, about 5 to 6 ounces each, from sustainable sources
  • Crushed red pepper, optional

INSTRUCTIONS

  • In a food processor, blend the garlic, lemon juice, olive oil, spices, salt, and pepper for about three minutes or until well-combined forming a thick and smooth marinade.
  • Pat the swordfish steaks dry and place them in a pan (or a dish with sides to it) and apply the marinade generously on both sides and set aside for 15 minutes or so while you heat the grill.
  • Preheat a gas grill on high (be sure to oil the grates before using). When ready, grill the fish steaks on high heat for 5 to 6 minutes on one side, turn over once, and grill on the other side for 3 minutes or so (the fish should flake easily, while maintaining firmness. You will likely see a bit of pink on the inside, but it should cook through by the time it gets to the table).
  • Finish with a splash of fresh lemon juice and a sprinkle of crushed red pepper flakes if you like heat. Enjoy!

Ingredients

  • Garlic: anywhere from 6 to 12 garlic cloves. (I typically go heavier on fresh garlic than most people, opting for 12 garlic cloves. But because we’re adding a bit of lemon juice, the garlic is tamed a bit).
  • Extra virgin olive oil: a good ⅓ cup of quality extra virgin olive oil (you can find the Greek olive oils I use at our online shop here).
  • Lemon juice: about 2 tablespoons of fresh lemon juice
  • Spices: a trio of warm ground spices- 1 teaspoon coriander, ¾ teaspoon cumin, and ½ to 1 teaspoon of sweet paprika. A dash of kosher salt and black pepper in addition

How to make this grilled swordfish recipe (print-friendly recipe below)

  • Make the marinade – In the small bowl of a food processor fitted with a blade, add the garlic cloves, extra virgin olive oil, lemon juice, coriander, cumin, paprika, kosher salt, and black pepper. Run the processor for a few minutes until you arrive at a smooth marinade.
  • Marinate the fish – Pat the swordfish steaks dry and place in a glass dish. Pour the marinade over and be sure to cover the fish with it on both sides. Set aside to marinate while you heat the grill (about 15 minutes or so)
  • Grill on high heat – When ready, grill the fish steaks on high heat for 5 minutes on one side, then turn over once and grill on the other side for 3 minutes or so (you can do this on the gas grill or an indoor griddle). The fish should flake easily, while maintaining firmness. You will likely see a bit of pink on the inside, but by the time it gets to the table, it will have cooked through)
  • Serve – Off the grill, I like to hit the fish up quickly with a splash of fresh lemon juice. Garnish with fresh parsley and red pepper flakes, if you like heat, and serve!

INGREDIENTS

For the Lemon Garlic Mixture:

  • 2 TB salted butter, softened to room temp
  • 1 TB freshly chopped chives
  • 2 TB garlic cloves, minced
  • 1/8 tsp kosher salt
  • 1/4 tsp freshly ground black pepper
  • 1 TB juice from fresh lemon
  • 1TB grated lemon peel
  • For the Fish:
  • 2 TB olive oil
  • 2 (1-inch thick each) swordfish fillets, about 67 oz each
  • kosher salt and freshly ground black pepper

INSTRUCTIONS

  • Preheat the oven to 400F with a rack in the middle position. In a small pan, combine all Lemon Garlic Mixture ingredients and stir to fully combine. Set aside.
  • Use paper towels to pat-dry all excess moisture from the swordfish fillets. Evenly sprinkle both sides of fillets with pinches of kosher salt and freshly ground black pepper. Set aside.
  • In a large, oven-proof pan, heat the olive oil over medium-high heat. Once the oil is hot, add the swordfish fillets to the pan and let cook until browned on one side, about 3 minutes (do not move fish around much.) Carefully flip fish fillets over to the other side, turn the stove off, and immediately transfer the pan into the hot oven.
  • Let fish roast for about 5-6 minutes or just until the top is golden and the center is just cooked through. Take care not to overcook. A minute before fish is done cooking in the oven, cook a small pan of the prepared lemon-garlic mixture over medium-high heat, constantly stirring, just until melted and bubbly. Immediately turn the heat off and pour the mixture over the cooked fish. Be sure to pour on any juices from the swordfish pan as well.
