History of Swordfish
Swordfish (Xiphias gladius), also known as broadbills in some countries, are large, highly migratory, predatory fish characterized by a long, flat bill. they are a popular sport fish of the billfish category, though elusive. 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).
Swordfish, xiphias gladius (Linnaeus, 1758), aka broadbills, are named for their long “bill” and, although they resemble members of the billfish family istiophoridae, they are actually the sole member of the xiphiidae family.
Xiphias gladius fisheries are active in tropical and temperate waters worldwide. The nations with the highest Xiphias gladius catches in the north atlantic are spain, the USA, Canada, Portugal, and Japan. Brazil, Japan, Spain, Taiwan, and uruguay are the nations that catch the most swordfish in the south atlantic. In 1995, the Atlantic swordfish industry caught 36,645 tons, or 41 % of the world total catch of swordfish.
Distribution and habitat
The swordfish is found in oceanic regions worldwide, including the Atlantic, Pacific, and Indian Oceans. it is found in tropical, temperate, and sometimes cold waters, with a latitudinal range of approximately 60°N to 45°S.
The Xiphias gladius is found throughout the tropical and temperate Atlantic, New zealand, Hawaii and Japan; and in the south pacific north to california, probably passing the winter in mid-ocean. On the eastern sicle (of the Atlantic) it ranges from the vicinity of cape town, south africa, northward in the summer months to the Mediterranean, where it is abundant, and while somewhat less common in British waters, has been taken in the Baltic, In general, it appears on these coasts only during the warmer seasons, but with numerous records for october and november on what is considered the northern part of its range.
Swordfish typically forage in deep water during the day and stay in the mixed layer at night (Abascal et al. 2010). based on records of forage organisms taken by Xiphias gladius, its depth distribution in the northwestern Pacific ranges normally from the surface to a depth of about 550.

Lifecycle of Swordfish
Swordfish Temperament / Behavior
The long bill is very sharp and it helps them to remain left alone from other forms of aquatic life. when they are threatened though they can use it to help them to have some type of defense against the predator.
They take part in jumping and many humans love to see this take place. The bill of the swordfish is longer than other billfishes and unlike other billfishes, swordfishes do not have teeth in their jaws, nor do mature Xiphias gladius have scales.
Swordfish are not schooling fish. They swim alone or in very loose aggregations, separated by as much as ten m (33 ft) from a neighboring swordfish. they are frequently found basking at the surface, airing their first dorsal fin. sometimes there will be numbers of them in an area such as basking at the surface of the water. they just tend to all be in the same area looking for food though.
Fully adult swordfish have few natural predators. Among marine mammals, killer whales sometimes prey on adult swordfish.
How to take care?
Swordfish are found throughout the “seven seas”, and most are caught mistreatment long, trailing lines. Nations and cultures everywhere the planet price this substantial, mild, meaty fish, and, as a result, from time to time they need been over-fished, notably in Asia and round the Mediterranean.
Feeding for Swordfish
Swordfish feed daily, most often at night, when they rise to surface and near-surface waters in search of smaller fish. They use their “sword” to slash larger prey whereas smaller prey are consumed whole. The long bill of the Swordfish permits it to slice at its prey. they are doing the most effective they’ll to injure it so they’re ready to catch it. they’re in no time, moving at accelerates to fifty miles per hour. this permits them to possess a plus over their prey.
They go after a good sort of prey, together with food fish, pelagics and invertebrates. They go after fish like rockfish and therefore the spiny-finned fish. Squid conjointly conjure a giant a part of their diet. they have a tendency to try to to most of their sorting out food at nighttime. they’ll consume massive amounts of food because of their size.
Health and Diseases:
Swordfish can weigh hundreds of pounds and grow to reach several feet in length. These naturally oily fish are common as grilled steaks with marinades or herbs.
Best food for Swordfish:
They feed mostly upon pelagic fishes, and occasionally squids and other cephalopods. At lower depths they feed upon demersal fishes. Adults feed on a wide range of pelagic fish, like mackerel, barracudinas, hake, rockfish, herring, and lanternfishes, however they additionally take demersal fish, squid, and crustaceans.
The sword is seemingly employed in getting prey, as squid and cuttlefishes unremarkably exhibit slashes to the body once taken from swordfish stomachs. massive prey are generally slashed with the sword, whereas tiny are enclosed whole.
