Spearfishing
Spearfishing is a method of fishing that involves impaling the fish with a straight pointed object such as a spear, gig or harpoon. It has been deployed in artisanal fishing throughout the world for millennia. Early civilisations were familiar with the custom of spearing fish from rivers and streams using sharpened sticks. Modern spearfishing usually involves the use of underwater swimming gear and slingshot-like elastic powered spearguns or compressed gas powered pneumatic spearguns, which launch a tethered underwater projectile to strike the target fish. Specialised techniques and equipment have been developed for various types of aquatic environments and target fish. Spearfishing may be done using free-diving, snorkelling or scuba diving techniques, but spearfishing while using scuba equipment is illegal in some countries. The use of mechanically powered spearguns is also outlawed in some countries and jurisdictions such as New Zealand. Spearfishing uses no bait and is ...

Free-diving
Freediving, free-diving, free diving, breath-hold diving, or skin diving is a form of underwater diving that relies on breath-holding until resurfacing rather than the use of breathing apparatus such as scuba gear. Besides the limits of breath-hold, immersion in water and exposure to high ambient pressure also have physiological effects that limit the depths and duration possible in freediving. Examples of freediving activities are traditional fishing techniques, competitive and non-competitive freediving, competitive and non-competitive spearfishing and freediving photography, synchronised swimming, underwater football, underwater rugby, underwater hockey, underwater target shooting and snorkeling. There are also a range of "competitive apnea" disciplines; in which competitors attempt to attain great depths, times, or distances on a single breath. Historically, the term ''free diving'' was also used to refer to scuba diving, due to the freedom of movement compared with surfa ...

Speargun
A speargun is a ranged underwater fishing device designed to launch a tethered spear or harpoon to impale fish or other marine animals and targets. Spearguns are used in sport fishing and underwater target shooting. The two basic types are ''pneumatic'' and ''elastic'' (powered by rubber bands). Spear types come in a number of varieties including threaded, break-away and lined. Floats and buoys are common accessories when targeting larger fish. Components The basic components of a speargun are a spear, a stock or barrel, and a handle or grip containing a trigger mechanism. Spearguns are usually from long, round or roughly rectangular from in diameter/width. Types of spearguns Spearguns are, most often, divided according to propulsion method, with the two common variants being rubber (or band) powered, and air powered (pneumatic). Band-powered spearguns, which are the simplest and cheapest to maintain, with rubber being the predominant material, come in two types: those made ...

Gigging
Gigging is the practice of hunting fish or small game with a gig or similar multi-pronged spear. Commonly harvested wildlife include freshwater suckers, saltwater flounder, and small game, such as frogs. A gig can refer to any long pole which has been tipped with a multi-pronged spear. The gig pole ranges in length from 8 to 14 feet for fish gigs and 5 to 8 feet for frog gigs. A gig typically has three or four barbed tines similar to a trident; however gigs can be made with any number of tines. In the past people would attach illuminated pine knots to the end of gigs at night to give them light. Sucker gigging Suckers are a bottom-feeding fish common throughout many parts of the US. The gigging of suckers for food occurs predominantly in southern Missouri and northern Arkansas, in the region referred to as the Ozarks. Sucker gigging is usually done at night with lights to maximize the visibility of the fast moving fish. Ozarks residents of the past often waded the clear l ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Snorkelling
Snorkeling ( British and Commonwealth English spelling: snorkelling) is the practice of swimming on or through a body of water while equipped with a diving mask, a shaped breathing tube called a snorkel, and usually swimfins. In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler to observe underwater attractions for extended periods with relatively little effort and to breathe while face-down at the surface. Snorkeling is a popular recreational activity, particularly at tropical resort locations. It provides the opportunity to observe underwater life in a natural setting without the complicated equipment and training required for scuba diving. It appeals to all ages because of how little effort is involved and is the basis of the two surface disciplines of the underwater sport of finswimming. Snorkeling is also used by scuba divers when on the surface, in underwater sports such as underwater hockey and underwater rugby, and as part of water-ba ...

The Histories (Polybius)
Polybius’ ''Histories'' ( grc-gre, Ἱστορίαι ''Historíai'') were originally written in 40 volumes, only the first five of which are extant in their entirety. The bulk of the work was passed down through collections of excerpts kept in libraries in the Byzantine Empire. Polybius, a historian from the Greek city of Megalopolis in Arcadia, was taken as a hostage to Rome after the Roman victory in the Third Macedonian War (171–168 BC), and there he began to write an account of the rise of Rome to a great power. Content Polybius' ''Histories'' begin in the year 264 BC and end in 146 BC (Polybius was born around 200 BC and died around 117 BC). He is primarily concerned with the 53 years in which Ancient Rome became a dominant world power. This period, from 220–167 BC, saw Rome subjugate Carthage and gain control over Hellenistic Greece. Books I through V cover the affairs of important states at the time (Ptolemaic Egypt, Hellenistic Greece, Macedon) and deal extensiv ...

Oppian
Oppian ( grc, Ὀππιανός, ; la, Oppianus), also known as Oppian of Anazarbus, of Corycus, or of Cilicia, was a 2nd-century Greco-Roman poet during the reign of the emperors Marcus Aurelius and Commodus, who composed the ''Halieutica'', a five-book didactic epic on fishing. Biography Oppian states that he is from 'the city of Hermes' and the 'city at the promontory of Sarpedon'. This has been supplemented by information from the biographies attached to medieval manuscripts, which state that his birthplace was Caesarea (now known as Anazarbus) or Corycus in Cilicia, or Corycus according to the Suda. All these cities were in the list of Roman provinces, Roman province of Cilicia. He composed a didactic poem in ancient Greek language, Greek hexameter on fishing (, ). It is about 3500 lines and bears a dedication to Marcus Aurelius and his son Commodus, placing it to the time of their joint rule (176-180 AD). A later didactic poem on hunting, the ''Cynegetica'' (, ), was also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retiarius
A ''retiarius'' (plural ''retiarii''; literally, "net-man" in Latin) was a Roman gladiator who fought with equipment styled on that of a fisherman: a weighted net (''rete'' (3rd decl.), hence the name), a three-pointed trident (''fuscina'' or ''tridens''), and a dagger (''pugio''). The ''retiarius'' was lightly armoured, wearing an arm guard ('' manica'') and a shoulder guard (''galerus''). Typically, his clothing consisted only of a loincloth (''subligaculum'') held in place by a wide belt, or of a short tunic with light padding. He wore no head protection or footwear. The ''retiarius'' was routinely pitted against a heavily armed ''secutor''. The net-fighter made up for his lack of protective gear by using his speed and agility to avoid his opponent's attacks and waiting for the opportunity to strike. He first tried to throw his net over his rival. If this succeeded, he attacked with his trident while his adversary was entangled. Another tactic was to ensnare his enemy's weap ...

Gladiator
A gladiator ( la, gladiator, "swordsman", from , "sword") was an armed combatant who entertained audiences in the Roman Republic and Roman Empire in violent confrontations with other gladiators, wild animals, and condemned criminals. Some gladiators were volunteers who risked their lives and their legal and social standing by appearing in the arena. Most were despised as slaves, schooled under harsh conditions, socially marginalized, and segregated even in death. Irrespective of their origin, gladiators offered spectators an example of Rome's martial ethics and, in fighting or dying well, they could inspire admiration and popular acclaim. They were celebrated in high and low art, and their value as entertainers was commemorated in precious and commonplace objects throughout the Roman world. The origin of gladiatorial combat is open to debate. There is evidence of it in funeral rites during the Punic Wars of the 3rd century BC, and thereafter it rapidly became an essential fea ...

Bible
The Bible (from Koine Greek , , 'the books') is a collection of religious texts or scriptures that are held to be sacred in Christianity, Judaism, Samaritanism, and many other religions. The Bible is an anthologya compilation of texts of a variety of forms originally written in Hebrew, Aramaic, and Koine Greek. These texts include instructions, stories, poetry, and prophecies, among other genres. The collection of materials that are accepted as part of the Bible by a particular religious tradition or community is called a biblical canon. Believers in the Bible generally consider it to be a product of divine inspiration, but the way they understand what that means and interpret the text can vary. The religious texts were compiled by different religious communities into various official collections. The earliest contained the first five books of the Bible. It is called the Torah in Hebrew and the Pentateuch (meaning ''five books'') in Greek; the second oldest part was a coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
