Swordfish of ferocious, and often attack large whales and other fish, the reproductive season for 8 to 9 months to fish and cephalopods as food, often swam near and out of the water, not in groups. Succulent and delicious. Fast travel speed, maximum speed of 103.8 km (a fish swimming in second place after the Swordfish). When it's time to chase schools of fish everywhere, wild guesses, long profit "sword" to hurt a lot of fish, and then slowly swallow eat. Moreover, the swordfish will attack the sea, "bully" - killer whales and sharks bite people, and even boats. Why Swordfish attack ships it? Currently there are three kinds of academic explanations: One is that swordfish swimming speed fast, with the same speed rifle bullet fired, they are anxious to avoid travel in time to ship, so often associated with collisions, will benefit "the sword" thorn inside. Another attack that the swordfish with the habits of whales, may be the fault of vessels at sea when the whale, which only attacks. Another is that the activities of vessels at sea disrupted the lives of swordfish, which provoked them to ship impact. However, the Swordfish attack ships will bring great trouble to themselves, their interest long "sword" pierce the vessel later, tend to pull it out. To restore the freedom, unless the broken snout. Swordfish distributed in tropical, subtropical and temperate oceans, the East China Sea, South China Sea and Taiwan are also distributed along the coast, the small number of ornamental fish are rare. "Living torpedo" - swordfish The end of World War II, the British steamer "Barbara" was being made regular voyages across the Atlantic. Suddenly, the duty sailor uttered a desperate scream: "Torpedo! Port found torpedoes!." Then immediately sound an alarm on the ship, the crew panic a heap, all flocking to the deck. Mad camel master helmsman turning the rudder, hard to change the course. Looked from the port, you can clearly see a black oval things very rapidly rushing towards the ship, then _set_ off a Road whitecaps. After a while, just listen to a deafening bang ... .... People on board had been terrified, but strange, ships did not explode. Then it was discovered, ships broke a big hole in bottom seawater surging into the room. And that terrible "torpedo" has left the ship, and rushed toward another direction. Originally, it was a huge swordfish - "live torpedo." Swordfish is meat fish. The stomach was found in a few swordfish tail pomfret, a bigeye fish, twelve horse mackerel and its larvae. Swordfish feed method is very special, as if watching his prey to see it jump in a "dance of death." When it entered the mackerel and fish, the body will be placed flat leaps from the water, after a few hops, the majority of mackerel are 被震 faint. At this point, it at lightning speed in the fish I caught, is soon stabbed to death with a sword dozens of mackerel, and then they devoured meal. British warship "Liebolite" in the sea 600 km southwest of Liverpool on the attack several times by the swordfish. Time, the ship's officers are preparing for morning exercise training, Suddenly he heard a loud noise, all the staff do not know what happened. One view, the original anchor at the stern side of the swordfish with a piercing ship plate, it is break Yu Tao, said at that moment, I do not know who is accurate with a thick rope to entangle its tail, Large swordfish are hanging on the deck. The measure, which is 5.28 m length of the end of swordfish, where "the sword" there is 1.54 meters long and weighs 660 kg. A long time ago, when the ship also are made of wood, the British insurance company listed in respect of the insurance program, "Swordfish attack ships suffered damage insurance" paragraph. In the UK Ken Xige Dayton Museum of Natural History in the history of the city, also on display were attacked and damaged vessels swordfish and swordfish are the ship breaking "sword." Thus, at the time of the dangers of swordfish is very serious. In 1944, somewhere in South Africa there was a large sea swordfish, it fiercely with their "sword" expose a fishing boat, and give the water the boat. Suddenly, even the boat people have been involved with water. Swordfish meat is very delicious, so fishermen never miss the opportunity to capture it. As long as after the Swordfish mostly alone, so little significance in fisheries catch. However, the swordfish has a special habit it is like to mix in the tuna fish and therefore generally have tuna fish place, we can often see swordfish. But the catch swordfish is not an easy task, for it is futile to use a variety of nets, the only tool that can capture its harpoon, which is a very risky business. Swordfish are often wounded suddenly dive into the sea, then suddenly out of the sea, puncture, or overturned boats. So, be sure to catch swordfish and make full preparations.
