Swordfish (Xiphias gladius) are large, highly migratory. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. They reach a maximum size of 177 in. (455 cm) and 1,400 lb (650kg).
IGFA All tackle world record for a swordfish was a 1,182 lb (536.15 kg) specimen taken caught in Chile 1953.
The swordfish is named after its sharp bill, resembling a sword (Latin gladius), which together with its streamlined physique allows it to cut through the water with great ease and agility.
Contrary to belief the “sword” is not used to spear, but instead may be used to slash at its prey in order to injure the prey animal, to make for an easier catch.
Mainly the swordfish relies on its great speed and agility in the water to catch its prey.
Females grow larger than males, with males over 300 lb (135 kg) being rare. Females mature at 4-5 years of age in northwest Pacific while males mature first at about 3 to 4 years. In the North Pacific, batch spawning occurs in water warmer than 24 °C from March to July and year round in the equatorial Pacific.
Swordfish commonly eat Tuna, Dolphin (mahimahi), Squid, Tinker Mackerals, Flyingfish. Swordfish are thought to have few predators as adults although juveniles are vulnerable to predation by large pelagic fish.Swordfish feed daily, most often at night when they rise to surface and near-surface waters in search of smaller fish. They have been observed moving through schools of fish, thrashing their swords to kill or stun their prey and then quickly turning to consume their catch. In the western North Atlantic, squid is the most popular food item consumed.
While swordfish are cold blooded animals, they have special organs next to their eyes to heat their eyes & also their brain.
wordfish are not schooling fish. They swim alone or in very loose aggregations, separated by as much as 10 meters from a neighboring swordfish. They are frequently found basking at the surface, airing their first dorsal fin. Boaters report this to be a beautiful sight, as is the powerful jumping for which the species is known.
Recreational swordfishing throughout the world, and especially in South Florida, has gained tremendous popularity. With the ban on longlining along parts of the eastern seashore, swordfish populations are showing signs of recovery. The recovery is far from complete and is not a fraction of what it was in the 70’s when recreational swordfish was discovered off the coast of South Florida.
To catch a swordfish off Florida, most anglers drift live or dead baits in the Gulfstream. Boats drift beam to sea, which is why center consoles are so popular for this type of fishing. From Miami’s Government Cut, Haulover Inlet or Port Everglades, the run to the swordfish grounds is less than 20 miles. Given the speed of the Gulfstream though, and fishing the majority of the night, you may end up as far as 40 to 50 miles from your homeport. From talking to longliners who used to fish in our waters, swordfish can be found in various parts of the Gulfstream, but the majority of recreational anglers fish a corridor of water that is 3 to 4 miles wide, but starts in the upper Keys and ends in Palm Beach. The reason that this area is so popular is due to the bottom terrain. In this lane there are a series of rises and falls in the depth contour which provides upwelling and seems to hold bait better than open expanses of flat bottom. Swordfishing can also be done during the day.
