Xiphias gladius

It is huge, elongated and slightly flattened. It is covered with fine scales, and has grayish-white round spots on its bluish-brown body. The upper jaw of its mouth is like a sharp sword, very prominent, and the first dorsal fin with black spots on its back is higher than the body, and the middle part is about twice as high as the body, like a sail, or a fluttering flag, so people call this fish sailfish.

Distributed in tropical and subtropical waters of the Atlantic, Indian and Pacific Oceans, and also in the southern East China Sea and South China Sea. Sailfish are usually found above the warm water layer, densely distributed in the waters near the coast and islands, forming schools of varying numbers.

Inhabits above the warm water layer, very densely distributed in the waters near the coast and islands.

There are two common types of sailfish: the oriental sailfish and the gray sailfish. Also known as flat sail, swordfish, and swordfish. Sailfish are river fish, and are pelagic fish active in tropical and subtropical oceans. They are ferocious by nature and swim fast. When attacking a target, they can reach speeds of 110 miles per hour and can dive to a depth of 800 meters.

The fastest marine animal in the world: Sailfish is considered the fastest fish in a short distance. In a series of speed tests conducted in the fishing village of Longji, Florida, USA, a sailfish swam 91 meters in 3 seconds, equivalent to a speed of 109 kilometers per hour. (From the Guinness World Records)

When a sailfish swims, it retracts its high dorsal fin to reduce resistance; its sword-like snout quickly separates the water to both sides; it uses the method of constantly swinging its caudal peduncle and caudal fin to generate forward thrust, just like the propeller of a ship. In addition, with its streamlined body, developed muscles, and huge swinging force, it can move forward as fast as an arrow from a string, with a maximum speed of 190 kilometers per hour. Even at ordinary times, its speed is 90 to 110 kilometers per hour, making it the swimming champion in the ocean.

Male and female fish are easy to distinguish. Male fish in the mature reproductive period have bright colors, while male fish in the estrus stage have scattered and uneven star-shaped stripes on their bodies; female fish have darker colors and a wide and plump abdomen. Female fish ovulate for 6 to 7 days, with 10 to 20 eggs per day. Then remove the female fish and leave the male fish. The male fish is extremely caring for his offspring. The aerator gently increases oxygen, and do not stop. After about a week, the fry will break out of the membrane one after another.

Sailfish are carnivorous fish that often feed on trevally, squid, and saury. Fishing baits generally use fresh trevally, house trevally, flying fish, squid, squid, saury, etc. Plastic squid, small fish, prawns, and other baits can also be used.

Swordfish meat is tender and plump, and its muscle color is different, including white, light red, bright red, etc. It has extremely high nutritional value and is a high-quality fish ingredient. Swordfish meat is white and tendonous, with delicious meat and high nutritional value. It is suitable for making high-quality sashimi, fried food and refined products.

Swordfish is extremely rich in nutrients such as protein, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), calcium, magnesium and vitamin D, and the fish oil content is also high.
